AOAC 999.10 Determination of Arsenic in Water: Eurolabs Laboratory Testing Service
The determination of arsenic in water is a critical parameter for ensuring the safety and quality of drinking water supplies. The AOAC 999.10 method, also known as the Arsenic in Water by Hydride Generation Atomic Absorption Spectrometry method, is a widely accepted standard for detecting arsenic levels in water samples.
The AOAC International (Association of Official Analytical Chemists) is a non-profit organization that develops and publishes standards for analytical methods, including AOAC 999.10. This standard is based on the principles of atomic absorption spectrometry (AAS), which measures the absorption of light by atoms of an element in a sample.
Legal and Regulatory Framework
The determination of arsenic in water is regulated by various national and international agencies, including:
These regulations establish maximum allowable concentrations of arsenic in drinking water, which vary by country and region.
