Abstract

The pesticide risk due to spray drift, runoff or drainage has significant pressure on aquatic life
resources, which increases the possibility of toxic exposure and effects on aquatic ecosystems.
Thus, the purpose of this paper is to present an outline of adverse effects or toxicity of pesticide
active ingredients and degradates to aquatic life. Researchers have evaluated comprehensive
global insecticides contamination data for agricultural surface waters and found with hints of
insecticide concentration in samples, wherein potential reasons for these findings are failures of
current risk assessment procedures or farmers' non-adherence to pesticide application
prescriptions. What is more, due to the high toxicity of insecticides for aquatic organisms, these
short-term spurts lead to substantial and long-lasting adverse effects on aquatic communities. In
addition, insecticide concentrations in waters is supposedly well regulated, even then insecticides
are threatening global freshwater biodiversity and scientists fear for the loss of world's
freshwater ecosystems. Aquatic life contaminations may result from treatment as well as from
conditions such as improper use of pesticides, residues from preceding treatments in the soil and
cross-contamination. Aquatic organisms may die as a result of pesticide contamination, or they
may simply grow poorly, become more susceptible to disease, or become unsuitable for human
consumption. Insecticides can adversely impact aquatic macroarthropods which play many
important functional roles in wetland ecosystems including as predators of aquatic herbivores,
and trophic levels effect on aquatic community composition. For remedying, those who apply
chemicals to crops near aquaculture facilities should be aware of the potential risks of
contaminating those facilities. Identifying insecticides that pose low risk to aquatic
macroarthropods, amphibians and fishes might help to meet increased demands for food while
mitigating against potential negative effects on ecosystem functions. The researchers might
increase awareness and rise regulation of chemicals harmful to aquatic life, and manufacturers
should effort the best for making insecticides and herbicides safer for peoples.
