Role of Pesticides in Water Pollution

Manish Srivastava*, Bharti Malin, Anamika Srivastava, Anjali Yadav, Anjali Banger

Pesticides are some kind of chemicals which are used all over the world for controlling pests, weeds and diseases within crops and also for health care of animals and humans. These can be categorized as insecticides, rodenticides, herbicides, fungicides, nematocides, plant growth regulators and molluscicides. However, pesticides have proven beneficiary in crop yield and in reducing vector borne diseases, but they also poses various negative impacts on our environment. The irrelevant and uncontrolled uses of pesticides have caused serious threats to human health and ecosystems or whole environment. These can cause serious negative effects, even if used at a low amount. Water resources are being contaminated by the use of the pesticides. Water pollution is at rise due to persistent organic chemicals present in pesticides. Rainfall, drainage, microbial activity, application rate, soil temperature as well as mobility, solubility and half-life of pesticides are some of the factors which are responsible for the movement of pesticides residues to water. By using planned and safe dose, these risks can be minimized. We should protect our resources from contamination for their sustainable use in future; we should not only use these synthetic chemicals very carefully but also should be concerned about their metabolites and transformation products.
