EPA 200.9 Determination of Mercury by Cold Vapor Atomic Absorption
Comprehensive Guide to EPA 200.9 Determination of Mercury by Cold Vapor Atomic Absorption Testing Services
EPA 200.9 is a standardized laboratory test for determining mercury levels in water, soil, and other environmental samples using cold vapor atomic absorption spectroscopy (CV-AAS). This method is widely accepted as the most reliable and accurate technique for detecting trace amounts of mercury.
Relevant Standards:
Legal and Regulatory Framework:
The United States Environmental Protection Agency (EPA) has set a maximum contaminant level (MCL) for mercury in drinking water at 2.0 micrograms per liter (μg/L). Similarly, the European Unions Drinking Water Directive sets an MCL of 1.0 μg/L. These regulations require laboratories to conduct accurate and reliable testing for mercury levels.
Standard Development Organizations:
ISO, ASTM, EN, and TSE are international and national standard development organizations responsible for creating and maintaining standards for laboratory testing.
Evolution of Standards:
Standards evolve over time as new technologies and methods emerge. The EPA 200.9 method is regularly updated to reflect the latest advancements in CV-AAS technology.
