Use of Pesticides leads to Environmental degradation
Abstract: Pesticides are extensively used for agriculture but residues can reach aquaticecosystems, frequently. They are transferred from pytoplankton to fish and human, ultimately. Pyrethroid insecticides are utilized in place of organochlorine,organophosphorus and carbonate to control different forms of pests and raise yield. Pyrethroid intoxication causes cellular damage and increases freeradicals, which leads to lipid peroxidation and, ultimately, oxidative stress.To reduce damage to environment and biologicalsystems by pesticides should be played attention …
