Organochlorine Pesticide Residues in Cotton
topic
Organochlorine pesticide analysis extracts cotton textile specimens with acetone-petroleum ether mixtures, cleans extracts through Florisil columns, and quantifies chlorinated insecticide residues including DDT, endrin, dieldrin, and toxaphene by GC-ECD or GC-MS against certified reference standards at sub-milligram per kilogram detection limits.
Role
Addresses legacy organochlorine pesticide contamination in cotton grown in regions where banned persistent insecticides remain in agricultural soils, ensuring imported cotton textiles from Central Asia, Africa, and South Asia do not carry skin-bioavailable organochlorine residues above OEKO-TEX and national regulatory thresholds.
