The Effects of Pesticide Exposure on Waterbodies and Remediation

Pesticides and fertilizers are used carelessly in agricultural intensive crop production in order to develop high yield varieties.This protects the crop against pests, which in turn serves to improve the crop's quality and quantity.Several pathways, including runoff, spray drift, and leaching, allow pesticides to pollute the aquatic environment, endangering both aquatic life and human health.Whether they are invertebrates, fish, or primary producers, this exposure may have an impact on all levels of the biological hierarchy.Pesticides reduce oxygen, particulate organic carbon, and dissolved organic carbon levels in aquatic plants by reducing primary production and increasing respiration rates .Atrazine raises calcium levels in aquatic environments.Reduced precipitation of calcium carbonate (CaCO3) occurs when crystal development is inhibited or the pH decreases.Pesticides including organochlorine and atrazine raise levels of ammonium (NH4+), nitrate (NO3-), and sulphate (SO4).There are numerous techniques to remove pesticides.Aquatic contamination may be biologicalbioaugmentation, natural attenuation, and biostimulation, chemical -denitrification, reverse osmosis, electrodialysis, and catalytic denitrification.In order to manage the amount of harmful chemicals in water bodies, it is necessary to include monitoring measures for runoff events in the spraying process.One such approach is the suspended matter sampler, which may be used to measure particle-associated pesticides.
