Environmental Compartments

Pesticides are agents of global change, since they can be transported to environmental compartments, cause adverse effects on non-target species. The most worldwide used pesticide is glyphosate. Some studies have already shown adverse effects on aquatic species caused by glyphosate, which is triggering global discussions about its legislation and use. Brazil has up to date no prospect of reducing or banning the use of the three most used pesticides in the country, glyphosate, 2,4 D and atrazine. The knowledge on adverse effects of pesticides and other chemical contaminants in tropical species is still scarce, maybe because many do not have defined protocols for ecotoxicological test conditions. The purposes of the each chapter of this study were: (1) to investigate the global glyphosate concentrations in surface freshwaters, to compare the countries laws and to carry out environmental risk assessments; (2) to investigate the Brazilian concentrations of glyphosate, 2,4D and atrazine in surface freshwater, and to assess the potential environmental risks they represent; (3) to describe the steps and the challenges for culturing the tropical test species Chironomus xanthus as well as to discuss its current use in ecotoxicology. Information on glyphosate concentrations in surface freshwater is scarce and known values very irregular among the countries investigated, with 95% of the studied systems showing concentrations that represent a risk to aquatic species. Most countries evaluated did not have restrictive legislation for the glyphosate presence in water resources, resulting in the non-protection of aquatic organisms. There was an increase in the annual sales of 2,4D, atrazine and glyphosate between 2009 and 2018 in Brazil. Although most environment concentrations were below the limit allowed by Brazilian legislation, the observed concentrations represented a medium to high risk for ecosystems in 65%, 72% and 94% of the Brazilian states for 2,4 D, atrazine and glyphosate, respectively. The ecotoxicological effect of pesticides, as well as of other contaminants in freshwater sediments are very often performed with benthic macroinvertebrates. Chironomus xanthus has been increasingly used for the past of years. Therefore, conditions for Chironomus xanthus establishment, maintenance and operation in the laboratory are necessary, due to the absence of protocols for this species.

The Impact

The textile industry occupies a significant hold on the global economy. This substantial industry often generates a large volume of effluents exceeding the permissible limit of discharge in the different regions of the world. Therefore, textile effluents act as pollutants altering the natural composition of various components of the environment. This paper discusses the impact of textile-based pollutants on agriculture including plants, soil, water and fisheries. The observed result is significant because textile effluents exert a widespread negative impact on the respective respondents, though plants show few positive effects. Prior treatment of textile wastewater is necessary before applying it to the soil, as there is a possibility of affecting the plant ecosystem via soil media. Plants are benefitted in terms of germination and growth, due to irrigation by textile effluents with proper dilution. The physical and biochemical properties of water streams along with aquatic organisms are impacted by these specific discharges, leading to even severe deterioration of particular living creatures. Pollutants released from various steps of textile processing have adverse effects on the environment, disturbing the food chain, ecosystem, and overall ecological balance.

Bendiocarb is a broad-spectrum insecticide recommended for malaria control by the World Health Organization (WHO). Still, bendiocarb poses a toxic risk to populations of nontargeted aquatic organisms. Thus, our study was aimed to evaluate the sub-lethal effects of bendiocarb exposure on zebrafish (Danio rerio) embryos by assessing of physiological, developmental, and biochemical parameters. Bendiocarb-induced adverse effects on embryonic development, larval growth, heart rate, changes in phase II detoxifying enzyme glutathione-S-transferase (GST) activity, oxidative stress-related enzyme activities (superoxide dismutase (SOD), catalase (CAT)), and the damage-linked biomarker lipid peroxidation (LPO) in early life stage zebrafish were investigated. Our results highlight that the selected nonlethal concentrations (96 h median lethal concentration in this study was 32.52 mg/L−1) of bendiocarb inflicted adverse effects resulting in embryo deformities (96 h EC50 = 2.30 mg L−1), reduced body- and notochord length (above 0.75 and 0.39 mg L−1 bendiocarb concentrations at 96 hpf, respectively), oxidative stress, and altered heart rate (above 0.4 mg L−1 at 48 hpf) in the studied model system.

New Information

Pharmaceutically active compounds are only partially removed from wastewaters and hence may be major contaminants of freshwaters. Direct and indirect effects on aquatic organisms are reported at dilute concentrations. This study was focused on the possible effects of environmentally relevant concentrations (~1 µg L−1) of two psychoactive compounds on the behavior of freshwater crayfish. Experimental animals exposed to venlafaxine did not show any behavioral alteration. Crayfish exposed to the benzodiazepine oxazepam exhibited a significant alteration in the distance moved and activity, and the effects were different when individuals were ready for reproduction. Results suggested that even the low concentration of selected psychoactive pharmaceuticals could alter the behavioral patterns of crayfish, as reported for other pharmaceuticals. These results provide new information about the possible adverse effects of pharmaceuticals at dilute concentrations. From previous knowledge and our results, it is obvious that different compounds have different effects and the effects are even specific for different taxa. Detailed studies are therefore needed to assess the possible ecological consequences of particular substances, as well as for their mixtures.

Pharmaceutical drugs frequently found in treated effluents, lakes and rivers, can exhibit adverse effects on aquatic organisms. The present study focuses on the application of advanced oxidation processes as ozonation (O3), sonolysis (US), and their combined application (US+O3) for the degradation of diclofenac in wastewater. Under the applied conditions, all three systems proved to be able to induce diclofenac oxidation, leading to 22% of mineralization for O3and 36% for US process after 40 min of treatment. The synergy observed in the combined schemes, mainly due to the effects of US in enhancing the O3decomposition, led to a higher mineralization (about 40%) for 40-minute treatment and to a significantly higher mineralization level for shorter treatment duration.

The Difference

AbstractConcerns have been raised that microplastics (MP) can impact aquatic organisms by compromising their nutrition. However, little is understood about the mechanisms of the adverse effects of MP in suspension-feeders that routinely ingest particles of low nutritional value, such as mineral particles. We compared effects of non-edible particles (MP and kaolin) mixed with microalgae on the swimming and filtering behavior of a planktonic filtrator Daphnia magna; incubations with only algae served as controls. The following questions were addressed: (1) Are there differences in swimming movements between the daphnids exposed to MP and those exposed to kaolin? and (2) Whether occurrence of biofilm on the particle surface affects daphnid swimming and how these effects differ between the kaolin- and MP-exposed animals? We found that both kaolin and MP altered swimming, yet in opposite way, with a decrease of filtration-related movements in kaolin and their increase in MP. The difference was amplified in biofilm coated particles, indicating that daphnids spend more energy when swimming in suspension with MP, and even more when the MP have biofilm. The increased swimming activity of filtrators exposed to plastic litter decaying to microparticles may translate into changes in energy balance and growth.

The exponential growth of nanotechnology has led to the production of large quantities of nanomaterials for numerous industrial, technological, agricultural, environmental, food and many other applications. However, this huge production has raised growing concerns about the adverse effects that the release of these nanomaterials may have on the environment and on living organisms. Regarding the effects of QDs on aquatic organisms, existing data is scarce and often contradictory. Thus, more information is needed to understand the mechanisms associated with the potential toxicity of these nanomaterials in the aquatic environment. The toxicity of QDs (ZnS and CdS) was evaluated in the freshwater fish Danio rerio. The fishes were exposed for seven days to different concentrations of QDs (10, 100 and 1000 µg/L) individually and combined. Oxidative stress enzymes (catalase, superoxide dismutase and glutathione S-transferase), lipid peroxidation, HSP70 and total ubiquitin were assessed. In general, results suggest low to moderate toxicity as shown by the increase in catalase activity and lipid peroxidation levels. The QDs (ZnS and CdS) appear to cause more adverse effects singly than when tested combined. However, LPO results suggest that exposure to CdS singly caused more oxidative stress in zebrafish than ZnS or when the two QDs were tested combined. Levels of Zn and Cd measured in fish tissues indicate that both elements were bioaccumulated by fish and the concentrations increased in tissues according to the concentrations tested. The increase in HSP70 measured in fish exposed to 100 µg ZnS-QDs/L may be associated with high levels of Zn determined in fish tissues. No significant changes were detected for total ubiquitin. More experiments should be performed to fully understand the effects of QDs exposure to aquatic biota.
