Abstract:
The world’s oceans are a global reservoir of persistent organic pollutants to which humans and other animals are exposed. Although it is well known that these pollutants are potentially hazardous to human and environmental health, their impacts remain incompletely understood. We examined how persistent organic pollutants interact with the drug efflux transporter P-glycoprotein (P-gp), an evolutionarily conserved defense protein that is essential for protection against environmental toxicants. We identified specific congeners of organochlorine pesticides, polychlorinated biphenyls, and polybrominated diphenyl ethers that inhibit mouse and human P-gp, and determined their environmental levels in yellowfin tuna from the Gulf of Mexico. In addition, we solved the cocrystal structure of P-gp bound to one of these inhibitory pollutants, PBDE (polybrominated diphenyl ether)–100, providing the first view of pollutant binding to a drug transporter. The results demonstrate the potential for specific binding and inhibition of mammalian P-gp by ubiquitous congeners of persistent organic pollutants present in fish and other foods, and argue for further consideration of transporter inhibition in the assessment of the risk of exposure to these chemicals.

Abstract:
In 1994 and 1995, we investigated the relationship between stream morphology and water chemistry and levels of organochlorines (HCB, PCB, and DDT) in young-of-the-year brown trout (Salmo trutta) from 25 streams in southern Sweden. Contrary to earlier findings for lakes, we found a positive relationship between trophic status (total phosphorus) and uptake of persistent pollutants in stream biota (trout). This difference between benthic, stream environments and pelagic, lake environments may be related to processes affecting pollutant uptake, i.e., pollutant ``spiralling'' or the shift from heterotrophy to autotrophy in streams. Land use in the catchment area of the streams also affected pollutant levels in trout, with higher levels in agricultural landscapes and lower levels in forested areas. Size of catchment area, however, did not influence uptake of pollutants in trout. The results indicate that eutrophication of streams by agricultural activities and excessive nutrient loading may increase uptake of persistent pollutants in stream biota.

Abstract:
Abstract Persistent organic pollutants (POPs), especially dioxin-like chemicals, have been shown to have adverse effects on skeleton and these effects are likely to be mediated via the aryl hydrocarbon receptor (AHR). In spite of the extensive research, the characteristics of developmental effects of POPs are poorly known and the role of AHR in POP bone toxicity and skeletal development in general. In this project changes in bone morphology and strength as well as tissue matrix mechanics are studied by applying state of the art biomedical engineering methods. This allows understanding of the effects of dioxins exposure and AHR activity on the development and maturation of extracellular matrix in musculoskeletal tissues from a completely new perspective, and thereby improving the health risk assessment of POPs. In the present study skeletal properties of rats exposed maternally to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), Northern Contaminant Mixture (NCM) and Aroclor1254 (A1254) were studied for cross-sectional morphometric and biomechanical properties, and data were analysed with benchmark dose modelling. In addition, extracellular matrix properties were analysed using nanoindentation. Similar measurements were performed for adult wild-type and AHR-null mice after TCDD exposure. The same animals were also analysed for microstructural changes using micro-computed tomography and their bone cell activity was estimated from serum markers and gene expression. Analyses show decreased bone length and cross-sectional properties with consequently decreased bone strength. On the other hand, an increased trabecular BMD in response to NCM and A1254 was observed. In addition, bone matrix properties indicated delayed maturation or early senescence after maternal or adult exposure, respectively. The AHR is mainly responsible for bone toxicity of dioxin-like compounds and plays a role in bone development. This is likely due to disturbed bone remodeling as indicated by altered serum markers and gene expression. Overall these results indicate that POPs decrease bone strength, but the interpretation is difficult as there is more trabecular bone within cortical bone with compromised quality and increased porosity
Tiivistelmä Altistumisen pysyville orgaanisille ympäristökemikaaleille on todettu heikentävän luustoa. Dioksiinien ja dioksiininkaltaisten yhdisteiden vaikutusten on havaittu välittyvän aryylihiilivetyreseptorin (AHR) välityksellä. Huolimatta pitkään kestäneestä tutkimuksesta POP-yhdisteiden sikiönkehityksen aikaisen altistuksen vaikutukset ja etenkin niiden mekanismit ovat edelleen huonosti tunnettuja, samoin kuin AHR:n osuus POP-yhdisteiden luutoksisuudessa ja luuston kehityksessä ylipäätään. Tässä työssä tutkittiin luuston rakenteellisia ja mekaanisia ominaisuuksia niin perinteisillä kuin uusimmilla biolääketieteen tekniikan menetelmillä. Tutkimuksen tavoitteena on saada uutta tietoa POP-altistuksen ja AHR-aktiivisuuden vaikutuksista luuston kehitykseen ja luukudoksen ikääntymisprosesseihin, mikä edesauttaa kyseisten yhdisteiden riskinarviointia. Tutkimuksissa altistettiin kantavia rottaemoja 2,3,7,8-tetraklooridibenzo-p-dioksiinille (TCDD), pohjoiselle saasteseokselle ja kaupalliselle Arokloori 1254 PCB-seokselle. Sikiönkehityksen aikana altistuneiden jälkeläisten luuston poikkileikkausen morfologia ja biomekaaniset ominaisuudet mitattiin ja tulokset mallinnettiin vertailuannoksen määrittämiseksi. Lisäksi TCDD-altistettujen rottien luustomatriisin ominaisuuksia selvitettiin nanoindentaatiomenetelmällä. Samaa menetelmää käytettiin myös aikuisiässä TCDD:lle altistettujen villityypin hiirten ja AHR-poistogeenisiten hiirten tutkimiseen. Näiden hiirten luuston hienorakennetta mitattiin myös korkean resoluution mikro-tietokonetomografialla ja niiden luusolujen aktiivisuutta tutkittiin seerumin biomarkkerien ja luun muodostumiseen osallistuvien geenien ekspressiotasojen avulla. Sikiönkehityksen aikainen altistuminen pohjoiselle saasteseokselle ja Arokloori 1254:lle hidasti luiden pituuskasvua. Lisäksi luiden poikkileikkauspinta-alat olivat pienentyneet ja mekaaniset ominaisuudet heikentyneet. Toisaalta hohkaluun määrä oli lisääntynyt altistumisen seurauksena. Myös sikiönkehityksen aikainen altistuminen TCDD:lle hidasti luukudoksen kypsymistä ja johti aikuisiällä luukudoksen ennenaikaiseen vanhenemiseen. AHR:llä oli päärooli ainakin aikuisiän vaikutusten ilmenemiselle ja reseptorilla vaikutti olevan rooli luuston kehityksessä ylipäätään. Seerumin biomarkkereiden ja geeniekspression muutosten perusteella nämä vaikutukset johtuvat todennäköisesti luuston uusiutumisen häiriöistä. Yhteenvetona voidaan todeta, että POP-yhdisteet heikentävät luustoa, mutta tämän ilmiön diagnosoiminen on hankalaa, koska huonolaatuisen kuoriluun sisällä hohkaluun määrä on lisääntynyt

Abstract:
Water samples taken from nine English freshwater lakes from a mix of urban, rural, and remote locations on 13 occasions between April 2008 and February 2012 were analysed for selected non-dioxin like-PCBs, tri- through hexa-PBDEs, and the three main HBCD diastereomers (\(\alpha\)-, \(\beta\)-, and \(\gamma\)-HBCD). Concentrations of PCBs and HBCDs declined over the sampling period with half-lives of 3.8 and 5.1 years, respectively. In addition, concentrations of PCBs, HBCDs, tri- through deca-BDEs, and 32 selected NBFRs were measured in radiometrically-dated sediment core slices taken in summer 2011/2 from seven of the same English lakes. Temporal trends in contamination with “legacy” POPs generally accord with historical trends in UK manufacture and use, with PCB contamination at all lakes increasing from ~1950, peaking generally between the late-1960s and mid-1980s, before declining steadily thereafter. In contrast, at most sites, BDE-209 displayed generally smooth increases following its initial emergence, and showed no obvious levelling off trend. Contamination with some NBFRs displayed significantly increasing trends. Spatial variation in POPs contamination of the lakes studied was evident; with regression analysis suggesting concentrations are higher in lakes with surface areas that are small relative to their catchment area, and that are closer to areas of high population density. The estimated PCB burden in the British environment is 521 tons, with TBPH (281 tons) and BDE-209 (147 tons) following not far behind. Estimated UK burdens of the remaining target compounds were significantly lower.

Abstract:
Persistent organic pollutants (POPs) are substances that degrade slowly, are distributed wotldwide, bioaccumulate and are harmful to both animals and humans. The release of POPs to the environment was the preamble to human background contamination. In the mid-20th century it became clear to scientists and policy makers that even the mothers´ milk was contaminated by POPs. This led to national and global monitoring programs to assess the extent of contamination and subsequently to ban several POPs via the Stockholm Convention. The concentrations of dioxin, polychlorinated dibenzodioxins (PCDD), -furans (PCDF) and dioxin like polychlorinated biphenyls (DL-PCB) is analysed in a retrospektive time trend study. The findings show a faster decrease of dioxin concentrations 2002-2011, compared to the whole series, 1972-2011. The transfer of polybrominated diphenyl ethers from mother to child via the milk is investigated and a relationship between both the PBDE molecule’s size and time post partum of the sampling and the ability to transfer to the milk is found. A literature review concerning the POPs in human milk finds, in addition to accounting for POP concentrations; that some substances are investigated more thoroughly than others; DDT and PCB compared to Aldrine and Toxaphene and that certain geographical areas are more well-studied than others, e.g. Europe compared to Africa. The study also shows a strong over all need for better reporting protocols. To understand the current and emerging POPs present in mothers´ milk screening of a larger than normal sample of mothers´ milk can give new insights. The development of a method designed to tackle the problems of large fat rich sample and still to be as benign as possible to the analytes was undertaken. The method is subsequently applied to a both Swedish and Chinese pooled sample to show the differences in POP exposure between countries.

At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript. Paper 4: Manuscript.

Abstract:
Abstract Persistent organic pollutants (POPs) are ubiquitous and bioaccumulative man-made chemicals, resistant to chemical, biological and photolytic degradation and widely distributed to sediments, wildlife, and human. Many of these chemicals have adverse effects on a variety of targets, including the endocrine system, organogenesis and reproduction. Due to these effects and wide distribution, many of them are either banned or strictly controlled. However, because of persistency, they continue to interact with organisms globally. Despite the existing knowledge of the adverse effects of POPs, the effects of many chemicals on bone tissue are still poorly known. In the present study, we investigated the adverse effects of three common POPs, including tributyltin (TBT), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and perfluorooctanoic acid (PFOA) on the skeletal system. In vitro models were used to study the effects of PFOA in mouse and in human, and the co-effects of TBT and TCDD on differentiating osteoblasts and osteoclasts of mice. An in vivo model for mice was used to study the developmental effects of maternal PFOA-exposure on pups among with morphometrical and biomechanical property analyses. Mass-spectrometry was used to study the presence of PFOA in bones both in mice and in human, the latter acquired from the bone bank held in the Oulu University Hospital, Finland. The bones were also analyzed with cone beam computer tomography and microcomputer tomography. The results show that PFOA exposure in utero and during lactation leads to the accumulation of PFOA in bone, traceable even 17 months after exposure. PFOA exposure decreased the mineral density of the tibias and increased the medullary area. Nearly all of the human samples contained PFAS, including PFOA. PFOA also disturbed the differentiation of osteoblasts and with lower doses, increased bone resorption of osteoclasts both in mouse and human, the phenomenon being slightly stronger in mice. Co-exposure to TBT and TCDD led to decreased differentiation of osteoblasts and osteoclast, and the co-effect was partially synergistic in osteoblasts. These results show disruption of bone development, bone cell differentiation, and PFAS accumulation in bone. Further studies are recommended to evaluate the co-effects of different POPs and the possible effects of long-term accumulation of POPs in bone and other tissues
Tiivistelmä Pysyvät orgaaniset ympäristömyrkyt (POP-yhdisteet) ovat kemikaaleja, jotka ovat levinneet ihmisen toiminnan seurauksena laajalle ympäristöön, sen eliöihin ja ihmisiin. Monilla POP-yhdisteillä on haitallisia vaikutuksia esimerkiksi hormonaaliseen toimintaan, elinten muodostukseen ja hedelmällisyyteen. Toksisten vaikutusten ja niiden yleisyyden vuoksi monien POP-yhdisteiden käyttö on joko rajattua tai kielletty kokonaan. Laajan levinneisyytensä ja hitaan puoliintumisaikansa takia POP-yhdisteet ovat kuitenkin edelleen vuorovaikutuksessa ympäristön ja sen eliöiden kanssa. POP-yhdisteiden luustovaikutuksista tiedetään edelleen vähän. Tässä väitöskirjassa tutkittiin kolmen yleisen POP-yhdisteen, tributyylitinan (TBT), 2,3,7,8-tetraklooridibentso-p-dioksiinin (TCDD) ja perfluoro-oktaanihapon (PFOA), vaikutuksia luustoon. PFOA:n vaikutuksia hiiren ja ihmisen luustoon sekä TBT:n ja TCDD:n yhteisvaikutuksia hiiren erilaistuvien osteoblastien ja osteoklastien suhteen selvitettiin in vitro -malleilla. In vivo -mallilla tutkittiin hiiriemon PFOA-altistuksen vaikutusta syntyvien poikasten luuston kehitykseen ja remodelaatioon analysoimalla poikkileikekuvia sekä luiden biomekaanisia ominaisuuksia. Lisäksi luiden PFOA-pitoisuudet mitattiin massaspektrometrilla. Tutkimusta laajennettiin ihmiseen analysoimalla Oulun yliopistollisen sairaalan luupankkinäytteitä. Ihmisnäytteet analysoitiin myös kartiokeila-TT:n ja mikro-TT:n avulla. Tulosten mukaan PFOA kertyy luuhun; hiiriltä voitiin mitata PFOA-pitoisuuksia jopa 17 kuukautta altistumisen jälkeen. Lisäksi PFOA-altistus pienensi luun mineraalitiheyttä ja kasvatti luuydinontelon tilavuutta. Lähes kaikki ihmisluunäytteet sisälsivät PFOA:ta ja muita PFAS-yhdisteitä. Solukokeiden perusteella PFOA-altistus häiritsee osteoblastien erilaistumista ja pienillä pitoisuuksilla lisää osteoklastien luunhajotusta sekä hiirellä että ihmisellä. TBT:n ja TCDD:n yhteisaltistus vaikuttaa puolestaan vähentävän sekä osteoblastien että osteoklastien erilaistumista ja toimintaa; osteoblastien osalta yhteisvaikutus oli osaksi synergistinen. Väitöskirja antaa lisätietoa POP-yhdisteiden vaikutuksista luun kehitykseen ja luusolujen erilaistumiseen sekä PFAS-yhdisteiden kertymisestä luuhun. Väitöksessä myös suositellaan lisätutkimuksia yhdisteiden yhteisvaikutuksista sekä pitkän aikavälin ympäristökemikaalikertymän vaikutuksista luussa ja muissa kudoksissa

Abstract:
The bioaccumulation of persistent organic pollutants (POPs) is of particular environmental concern in top predators, which accumulate high concentrations of POPs that can cause adverse effects. Previous small scale studies found high concentrations of POPs in adult great skuas, Stercorarius skua, a top predator in the marine environment. This thesis investigates the factors affecting concentrations and patterns of POPs (contribution of individual POPs to the ΣPOPs) in the great skua across its breeding range in the north-east Atlantic. Clear differences between colonies in both concentration and pattern of POPs in adult plasma were not indicative of being caused by long range transport of POPs in the atmosphere. Variation in diet between colonies is the mostly likely explanation for these colony differences, with great skuas from some colonies having a greater proportion of fish in their diet whilst others eat more seabird prey. Although seabirds are often used in studies of POPs in the environment, the effect of migratory behaviour has not previously been studied in detail. By using a combination of global location sensor (GLS) loggers and feather stable isotopes from winter grown feathers, the wintering areas of individuals from three breeding populations of great skuas were identified. Great skuas spend the winter in three distinct areas across the North Atlantic, with birds from the same breeding colonies wintering in different areas. In two of the three breeding populations, wintering area explained a significant proportion of variation in organochlorines (OCs) concentrations and pattern. However in the colony with the highest concentrations of OCs, no effect of wintering area was found, possibly as a result of these great skuas feeding at a higher trophic level during the breeding season than other populations. Temporally, concentrations of OCs were higher in 1980 than 2008 in eggs, whilst newer contaminants polybrominated diphenyl ethers (PBDEs) and perfluorinated chemicals (PFASs) show the opposite trend. In conclusion, concentrations of POPs in the great skua were influenced primarily by breeding season diet with wintering area and sex also having small but significant effects on POPs. Wintering area explained the most variation in the pattern of POPs in great skuas. The POP concentrations found in this study exceeded those which have been found to cause adverse effects on the immune system and reproduction in other species of seabird.

Abstract:
Els Contaminants Organic Persistents (COPs), tals com PCB, PCDD/FS i PAHs, són un grup de compostos químics regulats per a la seva reducció o ja prohibits a causa de la seva persistència, potencial per a ser transportat llargues distàncies i la capacitat de bioacumular en xarxes tròfiques. El transport atmosfèric i la posterior deposició s'han descrit com els processos claus pels quals impacten àrees oceàniques remotes. Així mateix, en la interfície atmòsfera-oceà, que correspon al 70% de la superfície de la Terra, tenen lloc molts processos vitals que determinen el paper dels oceans com a dipòsit i reservori de COPs. La interpretació d'aquests processos no és senzilla a causa de la manca de mesures en àrees remotes de l'oceà i el desconeixement dels mecanismes dominants a diferents escales espacials i temporals.
Aquesta tesi doctoral està centrada en la modelització dels processos de transferència de COPs entre l'atmòsfera i els oceans a escales regionals i globals. Per primera vegada, dades derivades de satèl·lits s'han acoblat amb models multimèdia de contaminants i de caixes de nivell I-III, donant lloc a estimacions d'acord amb un factor de dos amb les measures en molts dels casos. Així mateix, s'ha mostrat la variabilitat dels processos de deposició i la importància de considerar processos biogeoquímics a gran escala quan s'avalua la dinàmica dels COPs. Estimacions globals del procés de deposició atmosfèrica dominant, i fluxes d'enfonsament i subducció també s'han dut a terme. S'ha vist que la difusió aire-aigua és la ruta predominant de introducció de contaminants a oceans per a COPs predominantment en la fase gas. En canvi, la deposició seca i humida és dominant per certes regions i per a contaminants que tendeixen a sorbir-se fortament a aerosols. D'altra banda, la metodologia desenvolupada s'ha implementat per a estimar els bescanvis atmosfera-oceà de carboni orgànic total. Sorprenentment aquestes estimacions apunten a fluxes elevats que podrien ajudar a tancar els balanços globals de carboni.
El destí dels contaminants a curta escala i un cop han entrat a la columna d'aigua s'ha investigat mitjançant un model dinàmic 0-D i un model acoblat hidrodinàmic-contaminant 1-D. S'ha recalcat el paper dels sediments en el reciclatge de contaminants i dels fluxes atmosfèrics. Així mateix s'ha vist que la influència dels sediments és especialment important per a aigües poc profundes (< 20 m) i la profunditat a la qual difonen en la columna d'aigua s'explica amb la interacció entre fluxes turbulents i d'enfonsament. Així doncs, en aquesta tesi i per primera vegada s'ha dut a terme un analisi exhaustiu de la turbulència vertical en la dinàmica dels COPs

Persistent organic pollutants (POPs), such as PCB, PCDD/FS and PAHs, are a group of chemicals targeted for reduction, or already banned, because of their persistence, potential for long-range transport and their ability to bioaccumulate in food-webs. Atmospheric transport and subsequent deposition has been described as the major process by which they impact remote oceanic areas. Additionally in the air-water interface, which accounts about the 70% of the Earth surface, take place many vital processes that determine the role of the oceans as a sink and as a reservoir of POPs. However the interpretation of these processes encounters difficulties because of the lack of measurements in the remote oceanic areas, and the lack of understanding of the dominant mechanisms at different spatial and temporal scales.
This PhD-thesis focuses on the modelling of the transfer processes of POPs between the atmosphere and the oceans at regional and global scales. Satellite derived data has been coupled with multimedia box-contaminant models of level I-III for the first time, yielding estimations in agreement within a factor of two with measurements, in most cases. Moreover, it is shown the noteworthy variability of atmospheric depositional fluxes and the importance of considering large biogeochemical processes in the oceans when evaluating the dynamics of POPs. Global estimations of the dominant atmospheric depositional, sinking and subduction fluxes have been also performed. It is seen that diffusive air-water exchange is the predominant route of introduction of contaminants to the oceans for POPs predominantly in the gaseous phase. However, dry and wet deposition become dominant in certain ocean regions and for compounds that sorb strongly to aerosols. Furthermore the developed methodology has also been implemented to estimate the atmosphere-ocean exchanges of total organic carbon. Surprisingly, these estimations point to high fluxes which could help to close the carbon budgets in the global carbon models.
The fate of contaminants on the short-time scale and once they enter the water column has been investigated by means of a 0-D dynamic model and a 1-D dynamic coupled contaminant-hydrodynamic model. It is stressed the role of sediments recycling contaminants and the atmospheric based fluxes. The influence of sediments is especially important for shallow water columns (< 20 m). The extent to which they diffuse in the water column is explained by the interplay between sinking and turbulent fluxes. In this thesis and for the first time a novel and comprehensive analysis of the vertical turbulence to the dynamics of POPs has been performed.
All these results have been published in scientific literature, are in press for publication or under review.

Abstract:
The present research explores the levels and patterns of accumulation of a wide range of persistent organic pollutants (POPs) in the human population. It assesses two major families of POPs, namely organochlorine compounds (OCs) and polybrominated diphenyl ethers (PBDEs), and focuses on the population of Catalonia, a Mediterranean country in South-West Europe with active agricultural and industrial sectors. The research described in this study is based on a public health survey conducted by the Government of Catalonia in 2002, which included a health exam and a blood testing for 919 individuals. Gas chromatography and mass spectrometry techniques have been used to determine the concentrations of these pollutants in the serum samples. This research has customised a methodology to better detect organochlorine compounds in human serum samples. It has also contrasted the POP concentrations with a set of socio-demographic factors, with a special focus on age, sex and body mass index (BMI). And nally, it provides complementary assessments on POPs in other locations of Catalonia, including the Flix township that hosts a chemical factory; and on mercury, which is a non-organic persistent pollutant, in the infant population of the Menorca island. In essence, this research navigates in a diversity of pollutants, research methodologies and geographic conditions to explore the linkages between environmental pollution and human health.
Aquest estudi avalua els nivells i els patrons d'acumulació d'un ampli ventall de contaminants orgànics persistents (COPs) en la població humana. Comprèn dues classes de COPs, específicament els compos- tos organoclorats (OCs) i els polibromodifenil eters (PBDEs), i se centra en la població de Catalunya, un país mediterrani del sud-oest d'Europa amb uns sectors agrícola i industrial actius. La recerca descrita en aquest estudi es basa en una enquesta de salut pública duta a terme per la Generalitat de Catalunya el 2002, que va incloure en examen de salut i l'extracció d'una mostra de sang per a 919 persones. Les concentracions d'aquests contaminants en les mostres de s erum es van determinat mitjan cant t ecniques de cromatogra a de gasos i espectrometria de masses. En aquesta recerca s'ha dissenyat una metodologia específica per tal de millorar la detecció dels compostos organoclorats en mostres de sèrum humà. A més, les concentracions de COPs s'han contrastat amb una sèrie de factors sòcio-demogràfics, amb una especial atenció al sexe, l'edat i l' índex de massa corporal (IMC). Finalment, l'estudi proporciona avaluacions complementàries sobre els COPs en altres llocs de Catalunya, incloent el municipi de Flix, que acull una fàabrica de productes químics; i sobre el mercuri, un contaminant persistent inorgànic, a la població infantil de l'illa de Menorca. En resum, aquesta recerca combina una diversitat de contaminants, mètodes analítics i àrees geogrà ques per tal d'explorar l'associació entre la contaminació medioambiental i la salut humana.

Abstract:
The problem of the negative impact of persistent organic pollutants (POPs) on public health and the environment is a global one. Nowadays, the solution of the POPs problem is one of the priority environmental tasks of the international community. Relevance of the problem of implementation of obligations of the Republic of Belarus on persistent organic pollutants lies in the fact that a certain amount of these substances still remains in the territory of our country. According to adopted and implemented programs on reduction and complete cessation of use of these substances, all stocks of polychlorinated biphenyls (PCBs) and obsolete pesticides in Belarus have to be destroyed by the end of the current decade.

Abstract:
Access to essential infrastructure services such as water, sanitation, and garbage collection can considerably affect children's environment and may play a significant role in shaping early childhood developmental and health outcomes. Using data from the Multiple Indicator Cluster Surveys (MICS) and the Demographic and Health Surveys (DHS) for 18 countries in Latin America and the Caribbean (LAC), we show a significant positive association between access to water and sanitation and early childhood development, as well as reduced instances of stunting. In addition, we identify a negative association between access to improved garbage collection services and the rates of stunting and underweight among children under five. Our findings are robust after using alternative measures for access and controlling for individual, maternal, and household factors, alongside considerations of household wealth and caregiver's stimulation activities. Similarly, the economic relevance of the relationship is highlighted by the substantial gap relative to the size of the vulnerable groups, persisting even after adjusting for confounding variables. Our results also suggest that households may be able to lessen the potential impact of pollutants through mitigation measures such as treating water to make it safe for consumption, using handwashing cleansers, and storing household trash in lidded containers. The current findings underscore the importance of investing in basic infrastructure services as a critical component of comprehensive strategies to enhance early childhood development and health in low- and middle-income countries. We emphasize the importance of considering the quality and type of infrastructure services alongside their availability. Future research should incorporate more complete and detailed data to improve understanding of the causal relationship between water, sanitation, and garbage collection and early childhood development, as well as the mechanisms underlying the observed associations.
