Ways to Measure Insecticides
Methods for measuring insecticides can be found in EPA 40 CFR 141.24 or via the listing: Analytical Methods Approved for Drinking Water Compliance Monitoring of Organic Contaminants, as well as the National Environmental Methods Index . Methods used for the analysis of insecticides normally encompass a multitude of organic analytes which can be analyzed using the same method (e.g., EPA Method 1699, used for the determination of selected organochlorine, organo-phosphorus, triazine, and pyrethroid insecticides in multi-media environmental samples by HRGC/HRMS). Insecticides may be concentrated from water and pulses of insecticides from applications or spills may be captured by using semi-permeable membrane devices .
