Feasibility of Monitoring Pesticide Breakthrough from Charcoal Columns

Abstract

Eel cholinesterase test tickets and procedures were tested and modified to be sensitive to Baygon, carbaryl, diazinon, Dursban, and malathion for the rapid detection of these pesticides in water. Detection limits for all the pesticides in water were below 10 ppm using the enzyme test tickets and pretreatment with bromine. The tickets were stable during storage at 4 C or 40 C for at least 8 months. Bimolecular rate constants were determined for the inhibition of cholinesterase in solution.
