“…Along with this we have determined pH of the above pesticide formulations in expired and unexpired condition. pH of the above compounds was reported in the research article “Toxicity effect of expired pesticides to freshwater fish, Labeo rohita ” [27]. Due to pH alteration there may be formation of unknown compounds which were not studied and there is a requirement for detailed investigation of those degraded products.…”

In order to investigate the effect of expired pesticides on the yield and growth rate of green algae Pseudokirchneriella subcapitata, a study was conducted as per the Organisation for Economic Cooperation and Development (OECD) guideline number 201. Fifteen expired pesticide formulations, most commonly used in Indian agriculture, were tested in comparison with their unexpired counterparts. The expired pesticide formulations studied belonged to various class and functional groups: organophosphate, pyrethroid-based insecticides; azole-based fungicides; acetamide, propionate, acetic acid-based herbicides; fungicides mixtures containing two actives—azole and dithiocarbamate. The toxicity endpoints of yield (EyC50: 0–72 h) and growth rate (ErC50: 0–72 h) of Pseudokirchneriella subcapitata for each pesticide formulation (both expired and unexpired pesticides) were determined statistically using TOXSTAT 3.5 version software. The results pointed out that some expired pesticide formulations exhibited higher toxicity to tested algal species, as compared to the corresponding unexpired pesticides. These data thus stress the need for greater care to dispose expired pesticides to water bodies, to avoid the effects on aquatic ecospecies tested.

“…Based on current European regulations, pesticide concentration in drinking water should not exceed 0.1 mg L −1 for a single pesticide (Council Directive 98/83/EC). However, in natural ecosystems the level of pesticides may be as much as 100 times higher (Satyavani et al 2011).…”

A pesticide is a chemical substance used for the disposal of pests, such as insects, weeds, invertebrates, or rodents. Pesticides interfere with the normal metabolism of the target species; however, some of them may inadvertently affect organisms other than those targeted. Increased quantities of pesticides in water disturb various ecological processes and may increase the mortality rate of various native species of flora and fauna. One of the groups of organisms that are at the greatest risk from the adverse effects of pesticides is the bivalves. This study was designed to assess the behavioural reaction of bivalves to widespread pesticides. As a representative example, the Polish native Unio tumidus (Philipsson 1788) was used. The study investigated different groups of toxic pesticides, such as herbicides (lenacil), insecticides (thiacloprid, DDT and dichlorvos), and fungicides (tebuconazole), in concentrations of 10 mg L −1 . The results showed various behavioural reactions of bivalves to the pesticides. The most evident were activity time and shell opening rate. Moreover, as a result of DDVP contamination, effects were recorded in terms of shell opening level as well as rapid onset of death. Among the five analysed plant protection products, the most toxic was DDVP. Its presence caused adductor muscle paralysis in all analysed individuals. The least toxic pesticides were DDT and thiacloprid. A strong reaction to lenacil was observed especially in the shell opening rate. Tebuconazole caused significant reductions in activity. Despite the fact that the impact of pesticides on ecosystems is under regular observation, with the use of a wide range of scientific techniques, the use of bivalves was shown to have considerable potential for water quality monitoring.

“…The most common movement of agrochemical from land to water bodies has been long established to be by runoff or drainage while the deposits left behind after using agrochemicals to control weeds, pests, and diseases are another cause of environmental contamination by agrochemicals (Carter andheather, 1995, Singh andMandal, 2013;Larson et al, 2010;Armstrong, et al, 2013). The presence of agrochemicals in natural water within acceptable concentration range could still pose dangerous effects as this could alter the water pH and then lead to acute toxicity of different organisms, especial shes in the water (Satyavani, et al, 2011;kock-Schulmeyer, et al, 2013).…”

The large number of agrochemical pollutants that are today found in our environment, including in the air, soil, and water, and that are primarily caused by human activity, has caused many issues for the residents. Environmentally susceptible places for agrochemicals include water bodies near agricultural fields, groundwater near the surface, habitats for other animals, and endangered species. It is possible for drinking water to get contaminated and skin exposure to rise when agricultural chemicals are employed in close proximity to residential areas. The study investigated the possibility of water pollution and the vulnerability of rural farmers to agrochemical toxicity. Ewekoro and Ikenne Local Government Area were randomly selected for the study. Geographical Positioning System (GPS) device was used to take the coordinates of farms where agrochemicals are applied and the residential buildings in close proximity to farm fields. Descriptive statistics, digital elevation model and near tool analysis (ArcGIS), atomic absorption spectrophotometer and human health risk analysis were tools employed for analysis in the study. The findings showed that the water bodies were highly contaminated with heavy metals with consequences of the residents to suffer carcinogenic and non-carcinogenic adverse effects. The study recommends advocacy campaign on safe use of agrochemicals, appropriate water use to reduce risk to human health and increase biodiversity sustainability while building of local water purifying facilities in the rural communities for safe water consumption is encouraged.
