Detergents and water temperature as factors in methyl parathion removal from denim fabrics

ConclusionsBased on the results of this investigation, contaminated denim fabrics should not be laundered in 30°C (85°F) temperature; hotter temperatures are more effective. Although detergents could not be statistically separated, heavy duty liquid detergents appeared to excel in providing higher levels of pesticide removal in water temperatures of 49°C and 60°C. To determine the optimal conditions for pesticide removal by laundering, additional investigations need to be made into the relationships between detergent, pesticide formulation, water temperature, and effects of multiple washings.
