Cited data on anthropogenic pollution of the estuaries in south Primorye (northwestern coast of the Japan Sea) are briefly reviewed and analyzed. The estuaries are ranked by concentration of pollutants in the sewage disposed to the rivers and by integrated abiotic index calculated as the sum of toxicity in the bottom sediments and concentration of petrohydrocarbons in water and grounds. By these parameters, the oligohaline estuaries of big rivers as the Razdolnaya and Artemovka have the highest level of pollution, the mesohaline estuaries as the Tesnaya, Gladkaya, and Kievka have the intermediate rank of anthropogenic impact, and the polyhaline estuaries of small rivers as the Sukhodol, Shkotovka, Barabashevka, and Ryazanovka are low polluted. The estuarine ecosystems are generally well-adapted to high variability of environmental factors, and therefore are highly resistant to anthropogenic pollution. There is concluded that, despite of considerable pollution in some cases, dynamics of the estuaries dwellers abundance is determined mainly by natural factors, first of all by the volume of freshwater discharge, the estuarine ecosystems in Primorye function normally, and the state of their biological resources is sufficient. Thus, fishery, aquaculture, and recreations have at present good prospects in the estuaries and adjacent marine and river waters, in parallel with other economic activity, as hydraulic constructions, certainly under condition of all requirements of the nature protection legislation and with ecological monitoring. For these water bodies, technological and economic development can successively coexist with traditional nature management and wildlife preserving.

Plastic and, particularly, microplastic (MP) pollution is a growing research theme, dedicated largely to marine systems. Occurring at the land–sea interface, estuarine habitats such as mangroves are at risk of plastic pollution. This study compared MP pollution (level, morphotype, polymer composition, size and colour) across four South African estuaries, in relation to the built and natural environment. Mouth status, surrounding human population densities and land-use practices influenced the level and type of MP pollution. Systems that were most at risk were predominantly open estuaries surrounded by high population densities and diverse land use types. Microplastic levels and the diversity of types detected increased with increasing levels of anthropogenic disturbance. Overall, microfibres dominated in estuarine water (69%) and mangrove sediment (51%). Polyethylene (43%) and polypropylene (23%) were the dominant polymers overall. Weathered fishing gear, weathered packaging items and run-off from urban/industrial centres are probable sources of MP pollution. Increased run-off and river input during the wet/rainy season may explain the markedly higher MP loads in estuarine waters relative to the dry season. By contrast, MP deposition in mangrove sediment was higher during the dry season. Sediment MP abundance was significantly positively correlated with both pneumatophore density and sediment size (500–2000 µm). This study highlights the role of mangroves as MP sinks, which may limit movement of MPs into adjacent environments. However, under conditions such as flooding and extreme wave action, mangroves may shift from sinks to sources of plastic pollution.

Abstract Estuaries are profoundly rich, diverse, and complex ecosystems, and crucial to the overall health of Earth's oceans. Estuarine ecological complexity is matched by tremendous human cultural diversity. In the United States, millions of people live in estuarine environments from the Gulf of Mexico to the Arctic—many of whom directly depend on the productivity of marine resources in both commercial and subsistence fishing activities. Yet, estuaries are also among Earth's most threatened landscapes against the backdrop of global warming, sea-level rise, agricultural and industrial pollution, habitat loss, overfishing, and so on. This represents a looming disaster for our oceans at a global scale. The Estuarine Ecological Knowledge Network (EEKN) is based on the idea that fishing communities living within major estuaries are the key to ensuring the health of global oceans. Coastal fishing communities have vast accumulations of ecological knowledge about the functioning of estuarine ecosystems and interact with those ecosystems in intimate ways on a daily basis. This network is designed to connect coastal communities in monitoring the health of estuarine ecosystems and in using traditional ecological knowledge to develop strategies for enhancing ecosystem health and resilience.

SynopsisA current intensive mapping scheme for Forth seaweeds shows the normal attenuation gradient of species going upstream in the estuary with the existence of two areas of species depletion in the firth, around Kirkcaldy and Edinburgh. Ordination of species presence data suggests the continuation of estuarine influence into the firth and the possibility of slight differences in composition of the flora between the north and south banks in the mid and inner firth. Impoverishment of the flora around Edinburgh since the 19th century can be ascribed to increased pollution, but possibly also, to a lesser degree, to shore reclamation. Following abatement of sewage pollution, differences in the recovery of the algal flora on different shores may be related to the nature of the pollution-induced animal community. Recent work on the upper estuarine flora of the many small, highly-stratified sub-estuaries of the Forth system has revealed a marked shore zonation pattern of smaller mat-forming species.

Utilizing data primarily from the U.S. Department of Commerce, both estuaries and watersheds for 78 U.S. systems are analyzed. Watersheds are classified according to total population and discrete subpopulations. The Vollenweider approach, which compares hydraulic loading to nutrient loading of lakes, is adapted to estuaries. By considering total population as a surrogate of point source nutrients, agricultural workers as a surrogate of non-point source toxics and nutrients and chemical + metal workers as a surrogate of point source toxics, we can estimate potential anthropogenic impacts on watersheds. When these surrogates are plotted against hydraulic loading, managers have a tool to identify estuaries most likely to be under greatest anthropogenic presaure. The estuaries with highest susceptibility from total population, as well as the estuaries with the the highest susceptibility to toxic stress, are identified. On a Vollenweider diagram, the phosphorous loadings of freshwater bodies are plotted as a function of hydraulic loading. The permissible-excessive phosphorous loadings have been both theoretically and empirically determined. We have replotted the freshwater data and added 33 U.S. estuary P loadings that were previously unavailable. Estuaries plot on the Vollenweider diagram as a continuum of fresh waterbodies, both in terms of hydraulic loading and phosphorus loading. Most estuaries appear to have permissible P loadings. Analysis of nutrient loading (normalized to hydraulic loading) versus water quality parameters like chlorophyll a indicates that estuaries are more efficient users of nutrients than are freshwater bodies, and that they reach a “nutrient saturation point”. Perhaps this is due to grazing or turbidity. It appears that, in general, the OECD eutrophication modeling approach is applicable to estuarine systems as well as lakes and impoundments.

The WPI is an important tool to summarize a large number of water quality data into simple terms which is one of the most effective ways to interrelate information on water quality trends. The information generated can help to guide policy makers on effective restoration, conservation and management of water resources. In this technique the weightage for various water quality parameters is assigned to be inversely proportional to the recommended standards for the corresponding parameters. Estuaries represent productive aquatic habitats and are characterized by dynamic biogeochemical processes. Water quality loss in estuaries is, therefore, one of the worst forms of water pollution. For the analysis of water parameters, the water samples were collected and preserved in pre-rinsed plastic bottles at monthly intervals during June 2011–May 2013 for the period of two years from the Dumas vicinity of Tapi estuary. Temperature and pH were analyzed in situ and other parameters were analyzed as per standard references. The WPI in the studied area in the first year ranged between 1.2334 to 7.8266 whereas it varied from 1.797 to 6.439 in second year of the study. The higher value of WPI was observed during the month of December and January in the first year and in the month of December in the second year indicating high polluted nature of the estuary. The overall study revealed the polluted nature of the water ranging from mild to severe during different months in the studied area. It was observed that estuarine environment was polluted by the impact of anthropogenic as well as industrial activities. This study is important as understanding the ecological status of the estuarine habitats is imperative for successful environmental management and sustainable development.

Abstract Global climate change effects will vary geographically, and effects on estuaries should be independently considered. This review of the impacts of climate change on the ecotoxicology of chemical contaminants aims to summarize responses that are specific to estuarine species. Estuarine organisms are uniquely adapted to large fluctuations in temperature, salinity, oxygen, and pH, and yet future changes in climate may make them more susceptible to chemical contaminants. Recent research has highlighted the interactive effects of chemical and nonchemical stressors on chemical uptake, metabolism, and organism survival. Assessments have revealed that the nature of the interaction between climate variables and chemical pollution will depend on estuarine species and life stage, duration and timing of exposure, prior stressor exposure, and contaminant class. A need for further research to elucidate mechanisms of toxicity under different abiotic conditions and to incorporate climate change factors into toxicity testing was identified. These efforts will improve environmental risk assessment of chemical contaminants and management capabilities under changing climate conditions.

Annotation:

Estuarine environments are suggested to be the final receivers of human pollution and are impacted by surrounding urbanization and compounds carried by the river waters that flow from the continent. Polycyclic aromatic hydrocarbons (PAHs) are among the contaminants that can reach estuaries and can directly affect marine conservation, being considered highly deleterious to organisms living in these environments. This research investigated the meiofauna of three estuaries exposed to different levels of urbanization and consequently different levels of PAH concentrations, in order to assess how these compounds and environmental factors affect the distribution, structure and diversity of these interstitial invertebrates. A total of 15 major meiofauna groups were identified, with Nematoda being the dominant taxon (74.64%), followed by Copepoda (9.55%) and Polychaeta (8.56%). It was possible to observe significant differences in all diversity indices studied in the estuaries. With the exception of average density, the diversity indices (richness, Shannon index and evenness) were higher in the reference estuary, Goiana estuarine system (GES). On the other hand, the Timbó estuarine system (TES) had the lowest Shannon index value and richness, while the Capibaribe estuarine system (CES) had the lowest evenness value. The latter two estuaries (TES and CES) presented intermediate and high levels of urbanization, respectively. The ecological quality assessment (EcoQ) in the studied estuaries was classified from Poor to Moderate and the estuary with the lowest demographic density in its surroundings, GES, showed a better ecological quality (Moderate EcoQ). A significant distance-based multivariate linear modelling regression (DistLM) was observed between the environmental variables and the density of the meiobenthic community, where PAHs and pH were the main contributors to organism variation. The sediments were characterized by predominance of very fine sand and silt-clay in the most polluted environments, while the control site environment (GES) was dominated by medium grains. The highest concentrations of PAHs were found in the most urbanized estuaries, and directly affected the structure of the interstitial benthic community. The metrics used in the present study proved to be adequate for assessing the environmental quality of the investigated estuaries.

Annotation:

Bramble Bay, an estuary with a long history of contamination, appears to have crossed multiple tipping points into a state of unstable biomass dominated by opportunistic species. In early 1996 mass mortality events began to affect the bay’s macrobenthic community within a few days of modest rainfall (30 mm) over the catchments. The numbers of wading birds and fish using the beach at such times greatly declined. Between mortality events the macrobenthos staged partial recoveries. However, 10 years later the beach had not attained the diversity of species it supported prior to 1996. Also, the riverine estuaries that drain the catchments had been severely affected. Monitoring in 1998 – 2000 showed that the abundance of riverine macrobenthos in six drainage systems was < 15% of that in 1972 – 1973 when these drainage systems were extensively surveyed and < 2.5% of that after extreme flooding in 1974. Remarkably, the variance of total abundance within estuaries had been reduced by 90 - 99%. Nearly all of the once-dominant peracarids had gone. Chemical tests could not explain this. Nor are other simplistic explanations credible, such as floods or changes in the rate of sedimentation, because only some components of the macrobenthos have been adversely affected. Most deposit feeders have been severely reduced, however, deposit-feeding annelids as well as suspension feeding molluscs and crustaceans have continued to thrive amongst the sediments.

Annotation:

The UK contains 5000 unlined historical landfills in the coastal zone currently at risk of erosion within the next 50 years. These rely on natural attenuation in surrounding sediment to reduce the contaminant load to the environment. This thesis investigates the extent and magnitude of sediment metal contamination from historical estuarine landfills. An intensive investigation of Newlands historical landfill, Essex, indicated elevated metal concentrations in surface and sub-surface sediments. Surface sediment concentrations were similar to other industrially impacted estuaries, whilst peak metal concentrations at c. 50 cm depth were indicative of industrial activity in the mid-20th Century. Below this depth, sediments were enriched with Pb (EF > 2) and Zn (EF = 1.5) indicative of an historic leachate plume that extends c. 15 m from the landfill site boundary. These sediments present a secondary source of diffuse pollution and a site contamination load of c. 1200 kg Pb. In-situ XRF was demonstrated as a rapid contamination screening tool for Fe, Pb, Sr and Zn enabling a broad-scale investigation of historical landfills across SE England. Sediment cores from eight sites containing both hazardous and inert waste were screened. Concentrations and EFs of Pb and Zn at depth were significantly higher in hazardous sites compared to inert sites. Spatial distributions of Pb and Zn were comparable to Newlands historical landfill. This indicates that diffuse pollution from historical landfill sites with similar chemical and physical attributes to Newlands is likely to present a regional, if not national problem, with UK historical landfills presenting contaminated sediments, comprising a significant, previously unidentified and unquantified diffuse pollution source in the coastal zone.

Annotation:

It is essential that estuarine modelling and surveying are carried out simultaneously because not only does the latter provide data required by the former but also the former is verified with data from the latter. This study integrates both research subjects from the panoramic point of view, aiming at improving modelling accuracy and reliability and increasing survey efficiency. Partially stratified estuaries are the most difficult types of estuaries to be modelled, in particular, the velocity field in such an estuary. A review of two commonly used methods to determine the velocity field, i. e., theoretical method and empirical method, revealed their inadequacies in real applications. Thus, a new approach using Kriging technique was originated and was tested on a finite element model of water quality. The model was formulated using a Galerkinfinite element method and was programmed in Fortran. Comparison between the simulation results and the field measurements for a salinity intrusion showed a high simulation accuracy. It is believed that the model in combination with the new approach would be a useful tool for estuarine modelling. The generalized Kriging method ensured that the new approach would be appropriate in practice. It was also applied to the investigation of sampling stations in the partially mixed estuary of the River Tees. It is essential to know how many sampling stations should be used and how they should be positioned. Two procedures were designed for solving the survey problems. They were the procedure of overall variance and the procedure of re-estimation. These procedures were capable of quantifing the relative significance of each sampling station and detecting redundant sampling stations. The 1975 survey was investigated, and useful conclusions were obtained.

Annotation:

The influence of sedimentary variables on the structure and function of infaunal estuarine and marine communities is well studied but less is known of the influence of biota on sediment properties. Feeding and burrowing activity, locomotion, the production of faecal pellets and biological secretions (bioturbation) have important implications for sediment structure, chemistry, transport characteristics and the flux of nutrients and contaminants. Although spatial and temporal patterns in bioturbation have been studied to some extent, little attention has been given to the effects of pollution. The present study examines the effects of an intertidal petrochemical discharge into the Humber estuary (UK), from BP chemicals (Saltend) Ltd on the structure and function of the communities. Field and laboratory techniques were used to determine the effects of community change on bioturbation potential. In addition, a laboratory flume was constructed to measure sediment erosion potential with field measurements being taken using a Cohesive Strength Meter (CSM). The physico-chemical properties of the sediment, changes to the infaunal community structure, bioturbation potential and the interaction of these variables were used to explain differences between the erosion potential of sediments subject to varying levels of contamination. The main study was carried out on the Saltend mudflats near Hull, with sites at various distances from the outfall being used. A further set of control sites on the adjacent, and largely unaffected, mudflat at Paull were also used. In terms of the sediment properties, sites closest to the outfall showed the greatest degree of anoxia and the highest chlorophyll-a and carbohydrate concentrations, with all three parameters being seasonally influenced. No consistent spatial or temporal patterns were found for any of the other parameters (water and organic content, particle size). Whilst the infaunal communities were characteristic of estuarine areas, macrobenthic community response followed the Pearson & Rosenberg (1978) model for organic discharges with high abundance and low species diversity being associated with the more polluted sediments. Close to the discharge, there was an impoverished community consisting predominantly of highly abundant oligochate worms. With increasing distance from the outfall, species diversity and biomass increased with Hediste diversicolor becoming increasingly dominant and the appearance of Corophium volutator, Streblospio shrubsolii and Macoma balthica. Bioturbation potential was significantly reduced (in terms of depth and burrow volume and density) by increasing effiuent concentrations and with proximity to the discharge. The diversity of both feeding and sediment modification guilds was also reduced as a result of the discharge. Both field and laboratory studies indicated a stabilising effect of this type of pollution. Using the CSM, critical shear stress values were found to be significantly lower from unpolluted sites, indicating higher erosion potential, than those from sites close to the discharge. As a result of this, the total mass of sediment eroded from unpolluted sites was significantly higher than that from polluted areas. A similar trend was observed in the laboratory with sediments treated with an effluent concentration of 32% being considerably more stable than untreated sediments. Flume studies also indicated the stabilising effect of pollution with suspended particulate matter (SPM) concentrations and mass of sediment being transported as bedload being significantly higher for unpolluted sediments. These differences in erosion potential were attributed to the direct effects of the effiuent on the physico-chemical properties of the sediment, the effects of the effiuent and sediment type on macrofaunal community structure and function and the differences in bioturbation potential between sites. The implications of these findings in the wider context of coastal management are discussed.

Water quality impairment due to anthropogenic activities affects fishery resources. Surface water bodies in the Niger Delta Region of Nigeria are being adversely impacted by the effects of pollution and the destruction of its fishery resources. This study was carried out to assess the impacts of anthropogenic activities on the fish compositions and diversity of Okerenkoko Estuarine, Delta State, Nigeria. Okerenkoko Estuarine (62.79 Km) was spatially stratified into five stations (Z1, Z2, Z3, Z4 and Z5) based on nearness to major anthropogenic activities. Temporal stratification covered June to December. Fish samples were collected for 7 months from each station at the study area with prior arrangement with the fishers. Fishing gears used were Mid – Water Drift Gill Net of mesh sizes 101 mm and 127 mm; Bottom Set Gill Net (50 – 100 m) of mesh size 76 mm, 101 mm and 127 mm; Hook and line (2 – 6 m) of hook sizes No. 5, No. 7, No. 8, No. 9, No. 12 and No. 15; Long Line (300 – 1000 m) of hook sizes No. 7, No. 8. Parameters determined were Numbers of Species, Abundance (%), Simpson and Shannon by using standard procedures. Data were analysed by using Excel (Window 10) and Palaeontological Statistics (Past Version 3.6). A total number of 1261 of fishes and 45 species belonging to 14 families were identified. Highest 383 (30.4 %) and least 152 (12.1 %) number of fishes were obtained in Z5 and Z4, respectively. The most abundant fish species recorded was Sardinella aurita 192 (15.2 %), while the least was Sphyraena afra 1 (0.1 %), respectively. Temporally, the highest 331 (26.2 %) and least 45 (3.6 %) fish species Occurred in December and September. Simpson index ranged from 0.69 to 0.89 in Z1 and Z3, Shannon (1.97, 2.98) occurred in Z4 and Z2, respectively. Fish biodiversity richness (0.69) of Okerenkoko Estuarine could be threatened.

DIPLANOAGAP: Distribution of Plastics in the North Atlantic Garbage Patch Ponta Delgada (Portugal) – Malaga (Spain) 17.08. – 12.09.2019 The expedition POS 536 is part of a multi-disciplinary research initiative of GEOMAR investigating the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus will be on the vertical transfer of plastic debris from the surface and near-surface waters to the deep sea and on the processes that mediate this transport. The obtained data will help to develop quantitative models that provide information about the level of plastic pollution in the different compartments of the open ocean (surface, water column, seafloor). Furthermore, the effects of plastic debris on marine organisms in the open ocean will be assessed. The cruise will provide data about the: (1) abundance of plastic debris with a minimum size of 100 μm as well as the composition of polymer types in the water column at different depths from the sea surface to the seafloor including the sediment, (2) abundance and composition of plastic debris in organic aggregates (“marine snow”), (3) in pelagic and benthic organisms (invertebrates and fish) and in fecal pellets, (4) abundance and the identity of biofoulers (bacteria, protozoans and metazoans) on the surface of plastic debris from different water depths, (5) identification of chemical compounds (“additives”) in the plastic debris and in water samples.
