Ozone depletion is resulting into increase in ultraviolet radiation level in the world. Exposure to UV radiation has been found to have negative effects on aquatic and terrestrial organisms. Adverse effect of natural solar and artificial ultraviolet-B and UV-A radiations was observed in crustacean species Daphnia magna in presence of retene and riboflavin. Daphnia magna exposed to artificial ultraviolet-B with retene causes maximum physiological changes and mortality, indicating that enhanced solar UV-B exposure could be lethal to aquatic fauna. Artificial UV-B had a stronger damaging effect than solar radiation and become highly toxic in presence of retene. Riboflavin is slightly phototoxic in presence of solar and artificial UV radiation. Results on mortality rate indicated highest mortality in retene + ultraviolet-B exposed group followed by riboflavin + artificial ultraviolet - B radiation. A dose and intensity dependent change in mortality rate was observed. Retene and riboflavin photoproducts with ultraviolet radiation generate reactive oxygen species leading to cell injury and mortality thus are threat to aquatic biodiversity.

Depletion of the ozone layer leads to increased ultraviolet radiation, which affects the growth and functioning of plants and leads to their various physiological, biochemical, morphological and ultrastructural changes. When studying the effect of ultraviolet radiation on seed sowing qualities and biometric indicators of morphological organs of plants of various cultures, scientists did not come to a consensus on the optimal parameters of its effects. For seeds of each plant variety, there is an optimal amount of energy absorbed, resulting in a maximum effect. Ecologically significant low ultraviolet radiation changes the metabolism of reactive oxygen species and plant antioxidant systems by increasing enzyme regulation. The relevance of studies in this direction is obvious, as it allows you to stimulate the germination of seeds with physical influences, increasing their laboratory and field germination. The authors obtained and published new data on comparison of sown, crop and antioxidant properties of seeds and seedlings, seed viability, microzelenium biomass formation and change of total antioxidant activity of vegetable crops after thermodehydration. As a continuation of these studies, the purpose of this work was to study the effect of ultraviolet radiation on the biochemical properties of plants. The total antioxidant activity of sugar beet and nougat sprouts in the experiment increased under the influence of stress ultraviolet radiation. Compared to control samples (germination according to GOST in the dark), under the influence of ultraviolet radiation, antioxidant activity increases by 11.4-17.4% otn. Ultraviolet radiation is damaging factors of plant growth and development, which is manifested at different stages of ontogenesis. Thus, sowing properties are reduced (germination of sugar beet seeds is less than control by 18%, in nougat seeds by 12%), above-ground biomass at the end of the germination period is less by 49.0% in sugar beet and by 16.5% in Abyssinian nougat. Resistance to the damaging effects of ultraviolet radiation depends on the genetic nature of the plant: in the experiment, the sprouts of the Abyssinian nuga turned out to be more resistant.

Relevance. One of the main components of the spectrum of sunlight is ultraviolet rays – invisible to the human eye short-wave radiation. The influence of these rays on plant life was considered insignificant until recently, but recent studies have shown the fallacy of such conclusions. Ultraviolet has a beneficial effect not only on the human body and animals, but also on plants, including – crops. The destruction of the ozone layer is currently continuing under the influence of anthropogenic factors. In this regard, the study of the effect of ultraviolet radiation on living organisms, including plants, is very relevant from both theoretical and practical points of view. The epidermis of plant leaves and seed shells are permeable to medium-and long-wave UV radiation, so of particular interest is the ultraviolet radiation of the Sun and artificial sources of ultraviolet radiation in the range of 400...180 nm.Purpose of work: to assess the nature of the impact of ultraviolet radiation in the time mode on watermelon seeds using cytogenetic analysis.Methods. The material for research was the seeds of the watermelon variety "Astrakhan". The studies were conducted in 2017-2018.Results. The results of studies have shown that long-term exposure to ultraviolet radiation can affect the physiological processes and anatomical structure of plants, as well as have serious genetic changes: aneuploidy, cytotomy, pyknosis and various chromosomal aberrations that lead to mutations or death of plants. However, plants acquire useful mutations with short-term exposure-0.5-2 hours, which can be used later in selection.

Climate change studies are of considerable interest in agriculture and environmental science. The objective of this research was to investigate the changes in photosynthetic pigments and other physiological and biochemical traits of durum wheat exposed to ultraviolet A, B and C radiation, elevated CO2 and water stress. The results showed that carotenoids, anthocyanins, flavonoids and proline content increased significantly by decreasing ultraviolet wavelength compared to control. Elevated CO2 increased only height and specific leaf area. Water stress induced a significant increase in carotenoids, anthocyanins, flavonoids, proline and protein content. Interaction of UV-C and water stress in ambient CO2 increased UV screen pigments and proline content, while under elevated CO2 these increments were alleviated. Interaction among UV-C radiation, elevated CO2 and water stress demonstrated a significant decrease in Fv/Fm, chlorophyll, protein, carbohydrates and specific leaf area compared to control. The results of this experiment illustrate that increased UV radiation and water stress induces an increase of screen pigments and elevated CO2 prevents accumulation of these pigments.

Damaging effects of ultraviolet radiation on the aquatic biota, related to anthropogenic modifications in the ozone layer, have been extensively described. However, most of the research has focused on marine environments, and information about the effects of ultraviolet radiation on saline prairie lakes of Canada is lacking. To test the deleterious effects of ultraviolet-B (UV-B) radiation on the planktonic community, two exposure experiments were performed in Redberry Lake, Saskatchewan. The responses of primary productivity, phytoplankton chlorophyll a and size, bacterial changes, and the electron transport system to natural UV-B fluxes reaching the surface of the lake were studied. No clear effects of UV-B on phytoplankton carbon assimilation and chlorophyll a were observed. However, significant responses were found for the two phytoplankton size fractions studied (0.7-2 and >2 µm), which were more related to the experimental conditions than to UV-B effects. Bacteria presented a clear decrease in cell number under the highest UV-B doses, whereas the opposite was observed for the electron transport system activity.

Nuclear sphingomyelin and phosphatidylcholine metabolism is involved in the response to ultraviolet radiation treatment in different ways related to the physiological state of cells. To evaluate the effects of low levels of radiation from the stratosphere on thyroid cells, proliferating and quiescent FRTL-5 cells were flown in a stratospheric balloon (BIRBA mission). After recovery, the activity of neutral sphingomyelinase, phosphatidylcholine-specific phospholipase C, sphingomyelin synthase, and reverse sphingomyelin synthase was assayed in purified nuclei and the nuclei-free fraction. In proliferating FRTL-5, space radiation stimulate nuclear neutral sphingomyelinase and reverse sphingomyelin synthase activity, whereas phosphatidylcholine-specific phospholipase C and sphingomyelin synthase were inhibited, thus inducing sphingomyelin degradation and phosphatidylcholine synthesis. This effect was lower in quiescent cells. The possible role of nuclear lipid metabolism in the thyroid damage induced by space radiations is discussed.

Abstract Over the past few decades, anthropogenic activities contributed to the depletion of the ozone layer, which increased the levels of solar ultraviolet-B (UV-B) radiation reaching the Earth`s surface. Generally, UV-B is harmful to all living organisms. It damages the cell`s Deoxyribonucleic acid (DNA), proteins, and lipids, and as a consequence, it affects the bio-membranes negatively. In this review, we summarize the major effects of UV-B in the plant`s main molecules and physiological reactions, in addition to the possible defence mechanisms against UV-B including accumulating UV-B absorbing pigments to alleviate the harmful impact of UV-B.

The effects of UV-B radiation were studied in sunflower plants (Helianthus annuus L. cv. Catissol-01) growning in greenhouse under natural photoperiod conditions. The plants received approximately 0.60Wm-2 (control) or 4.0Wm-2 (+UV-B) of UV-B radiation for 7h d-1, centered around solar noon from 15 days after sowing. Compared to the control, plants exposed to high UV-B radiation for 12 or 21 days did not show any difference in shoot dry matter, specific leaf weight or UV-B absorbing compounds. Enhanced UV-B radiation caused a significant inhibition of photosynthesis (A) only in the first sampling and this was accompained by reduction in stomatal conductance (g s) and transpiration rate. The inhibition in A can not be fully explained by reduction in g s since intercellular CO2 concentration was not affected by UV-B radiation. In both samplings, the total chlorophyll content was not affected by enhanced UV-B radiation whereas in the first sampling, the chlorophyll a and the ratio of chlorophyll a/b were reduced. Enhanced UV-B radiation increased the minimal fluorescence yield, but did not alter the ratio of variable to maximal fluorescence yield of dark adapted leaves. Overall, this study suggests that the present level of solar UV-B radiation affects sunflower plants performance even though the shoot dry biomass may not be affected.

The increased concentration of carbon dioxide (CO2) and other greenhouse effect gases has led to global warming, which has resulted in climate change, increased levels of ultraviolet (UV) radiation and changes in the hydrological cycle, affecting the growth, development, production and quality of fruit crops, which undoubtedly will be difficult to predict and generalize because the physiological processes of plants are multidimensional. This review outlines how the effects of high/low solar radiation, temperature, water stress from droughts, flooding and rising levels of CO2 in the atmosphere affect fruit crops and their growth and physiology.

Intumescences are a physiological disorder characterized by hypertrophy and possibly hyperplasia of plant tissue cells. Ultimately, this disorder results in the death of the affected cells. Previous observations and research suggest that the quality and quantity of light to which plants are exposed may be a factor in development of the disorder. The purpose of this study was to assess the preventive effect of ultraviolet-B (UVB) radiation on intumescence development in ornamental sweetpotato (Ipomoea batatas). Two sweetpotato cultivars, Sidekick Black and Ace of Spades, were grown under light treatments consisting of 1) normal greenhouse production conditions; 2) supplemental UVB lighting; 3) supplemental UVB lighting with Mylar® sleeves over the lamps to block UVB radiation; and 4) control lighting with full spectrum lamps. Treatments were administered for 2 weeks, and the experiment was repeated twice. ‘Ace of Spades’ was highly susceptible to intumescence development, whereas ‘Sidekick Black’ was much less susceptible to the disorder. For ‘Ace of Spades’, the addition of UVB radiation significantly reduced the number of leaves affected with intumescences when compared with plants grown under the other light treatments; this UVB effect was not apparent for ‘Sidekick Black’. Furthermore, there was no evidence for reduced plant growth under UVB light in either cultivar, but side effects from the radiation included leaf discoloration and deformities. This study indicates a cultivar-specific effect of UVB light in preventing intumescence development on ornamental sweetpotato, therefore suggesting a potential genetic component in intumescence susceptibility. These results provide further insight in better understanding intumescence development and how to prevent the disorder.

The capacity of human skin to increase it's pigmentation in response to sunlight is an important protective mechanism employed by the body against the potential harmful effects of excess ultraviolet radiation These include the development of skin cancer and premature aging of the skin. Intense scientific research, particularly over the past two decades, has led to a greater understanding of the biology of the pigment producing cells in the skin, melanocytes, and their secretory product, melanin. Melanocyte function in the skin depends on a delicate and complex interaction with the surrounding skin cells, systemic hormones and external stimuli, especially ultraviolet radiation from the sun.

The "DNA Damage Hypothesis" pertaining to the evolution of sex was tested using Hydra littoralis. DNA damage was produced by irradiating whole live hydra with ultraviolet light. A curve of uv light dosage vs. survival was constructed. Estimations of threshold fluence and LD50 were made from the survival curve. In four separate experiments, using various combinations of environmental temperatures, uv doses, and number of doses, frequencies of asexual and sexual reproduction were observed and compared. The hydra that received uv treatments did not show an increase in the consequent amount of sexual reproduction, and actually showed a decrease. An increase in the amount of sexual reproduction following DNA damage is predicted by the DNA damage hypothesis, therefore these results do not support this theory. The data was also used to make contradictory observations regarding the "stress hypothesis" for the occurrence of sexual reproduction in hydra.

Ultraviolet (UV) radiation damages both eukaryotic and prokaryotic cells by causing the formation of free radicals which damage cell membranes and DNA. Antioxidant vitamins have been shown to protect cells from UV-induced damage by scavenging free radicals. The protection of skin and its normal flora is necessary for the health of individuals in resisting diseases caused by microorganisms and delaying the long-term damage caused by UV radiation.This research investigated the effects of the antioxidants vitamin A and ascorbic acid, as well as UV-irradiation on both prokaryotic (Staphylococcus epidermidis) cells and eukaryotic (human fibroblast skin) cells. This information is important in determining the effects of vitamin treatment on skin and its normal flora.Results indicate that ascorbic acid is rapidly (within six hours) degraded after being dissolved in water or medium. Treatment of cells with ascorbic acid must take into account this rapid degradation. S.epidermidis cells were protected from UV-induced damage by treatment with ascorbic acid but were more sensitive to UV-irradiation when treated with vitamin A. Human fibroblast cells treated with ascorbic acid did not exhibit morphological changes when compared to untreated cells.

Alpine zooplankton are exposed to a variety of stressors in their natural environment including ultraviolet radiation. Physiological coping mechanisms such as the accumulation of photoprotective compounds provide these zooplankton protection from many of these stressors. Elevated levels of carotenoid compounds such as astaxanthin have been shown to help zooplankton survive longer when exposed to ultraviolet radiation presumably due to the strong antioxidant properties of carotenoid compounds. This antioxidant capacity is important because it may ameliorate natural and anthropogenic stressor-induced oxidative stress. While previous researchers have shown carotenoid compounds impart increased resistance to ultraviolet radiation in populations of zooplankton, little work has focused on the toxicological implications of PAH induced phototoxicity on zooplankton containing high levels of carotenoid compounds. This thesis discusses research studying the role that carotenoid compounds play in reducing PAH induced phototoxicity. By sampling different lakes at elevations ranging from 9,500' to 12,700' in the front range of the Colorado Rocky Mountains, copepod populations containing different levels of carotenoid compounds were obtained. These populations were then challenged with fluoranthene and ultraviolet radiation. Results discussed include differences in survival and levels of lipid peroxidation among populations exhibiting different levels of carotenoid compounds, and the toxicological and ecological implications of these results.

Resumo:

A new fabric transmission measuring system (FTMS) utilising a solar UV simulator and a broad band radiometer, has been designed and developed for fast assessment of the protection levels of clothing fabrics against the biological damage caused by sunlight. The radiometer has a spectral response similar to the erythema action spectrum for human skin. The advantages of the FTMS are simplicity, reliability, low cost and, most importantly, time-efficiency. It has a capacity to process sixty-five clothing samples in about twenty-five minutes. The FTMS was calibrated against a spectroradiometer. The error of the results obtained by the FTMS is estimated within ±8%. The FTMS was employed to study the effects of the parameters and conditions of clothing fabrics on the result of the erythema effective transmittance, i.e. the transmittance of irradiance weighted with the erythema action spectrum for human skin. It was observed that weave structure of clothing fabrics could change the transmittance by up to 11.2 times even though all other factors such as the colour and the dryness condition were maintained at constant. The variations of transmittance with various colours were up to about 200% for polyester(65%)/cotton(35%) samples, and 600% for cotton samples in the studies. A variation as high as about 20 times in transmittance was recorded by stretching lycra clothing fabrics. Wetness of clothing fabrics could change the erythema effective transmittance in either directions, i.e. increase and decrease, depending on the types of clothing fabrics. An increase of transmittance of about 3.1 times and a decrease of about 70% due to the wetness conditions were observed. A model was proposed to correlate the UV transmittance and the characteristics of clothing fabrics. The model was preliminarily tested and a correlation coefficient of 0.902 for the UV transmittance measured with the FTMS and the UV transmittance calculated by the model was obtained. The UV transmission through clothing fabrics is not only determined by the uncovered area of clothing fabrics, but also by the UVR scattering of clothing fabrics. Taking into account of the effects of UVR scattering by clothing fabrics would improve the results.

Resumo:

Ultraviolet radiation causes an alteration in DNA by modifying neighboring thymine bases resulting in the formation of a dimer. These dimers block the processes of transcription and translation and ultimately no protein is synthesized and the cell dies. However, DNA repair mechanisms correct this damage by excising the dimer from the DNA strand and inserting replacement bases which are joined to the original strand by DNA ligase. This allows transcription to resume and ultimately protein synthesis to take place.This research focused on determining the DNA damage and subsequent repair levels in a connective tissue disorder, namely Marfan syndrome. This information is important in understanding the clinical expression and management of life threatening conditions in Marfan syndrome individuals.Preliminary results indicate that at 20-25J/m2 UV dose (254nm) Marfan syndrome skin cells show a mean reduced survival value of 12% compared to normal human skin cells. Gel electrophoresis indicates a reduced DNA repair level 24h post UV irradiation for Marfan syndrome skin cells compared to normal human skin cells. These results suggest Marfan syndrome skin cells have reduced survival and DNA repair levels compared to normal human skin cells.

Resumo:

Irradiated Shade is an ongoing project that develops a means of uncovering, representing, and designing for the unseen dangers of ultraviolet radiation within conditions of apparent shade—a growing yet under-explored threat to cities, buildings, and bodies. The project leverages its position in the US-Mexico borderlands, a vital testing ground in which physiological effects of solar radiation are rendered upon vulnerable populations. This paper will discuss: the design context, considerations for ultraviolet (UV) radiation as a complex design problem, the limits of existing design tools to address conditions of UV at a building scale, and the development of custom architectural design tools to improve the ability to visualize and combat UV exposure. The paper introduces an algorithmic drawing technique capable of mapping the built environment from the perspective of UVB scatter, producing spherically-projected sky dome maps indicating the risk of UVB exposure in a particular location to sensitize designers to this hidden danger.
