Hazardous Herbicides are threatening life – humans, animals and the environment by contaminating the air, water and soil. These chemicals have various toxic effects (neurotoxicity (toxic to the nervous system) cytotoxicity (toxic to cells), reproductive toxicity, endocrine toxicity, carcinogenicity (can induce cancer), genotoxicity (toxic to genetic material DNA) and respiratory toxicity). They are a grave threat to the biosphere. They can drift away from the point of application easily to water resources through leaching or runoff water. They are a major threat to all ruminants and to other life forms through biomagnification, i.e., traveling along the food chain. Pesticide poisonings, intentional and accidental, involving herbicides are happening all over India, leading to deaths and debilitating chronic effects on the victims.
