Chemical Contamination in Agriculture: The Lasting Ecological and Health Effects of Pesticides

Abstract Pesticides are the natural or chemically synthesized compounds used in farming practices to protect crops from pests, weeds, and other insects. The increased use of pesticides in today’s agricultural practices poses serious risks to environmental ecosystems and has increased the negative health effects on humans. Pesticides endanger higher trophic levels and result in adverse health conditions such as cancer, acute and chronic poisoning, neurological disorders, and endocrine disruption by building up in the food chain. Industrial pesticides cause soil and air pollution and put the survival of various birds, insects, and other aquatic organisms in danger by reducing their food supplies, species diversity, and impairing reproduction resulting in the population decline of animals and plants. This emphasizes the importance of striking a balance between environmental and health sustainability and agricultural productivity. This review critically examines the adverse effects of chemical pesticides on water, plants, natural systems, and human health.
