EPA Method 8081 Instrumentation Guide

EPA Method 8081 is a widely used analytical method for the determination of organochlorine pesticides (OCPs) in environmental samples, including soil, water, and waste. Using Gas Chromatography with Electron Capture Detection (GC-ECD), this method ensures high sensitivity for detecting trace levels of pesticides that persist in the environment. It is essential for regulatory compliance, hazardous waste assessments, and environmental monitoring.
