ASTM D5673 Mercury Test in Water Validation Method Development Test
The ASTM D5673 standard provides a validated method for quantifying mercury (Hg) in water samples. This procedure is essential for environmental testing laboratories, especially those involved in water quality monitoring and compliance with stringent regulatory standards such as the USEPA’s 1624 and 1660.
Mercury contamination in aquatic environments poses significant risks to human health and ecosystems due to its bioaccumulation potential. This method is pivotal for ensuring accurate quantification of mercury species, which can vary widely depending on environmental conditions. The test measures both inorganic (Hg²⁺) and organic forms of mercury, covering a concentration range from 0.5 ng/L up to 10 μg/L.
The testing process involves several critical steps: sample collection, digestion, and the subsequent analysis using cold-vapor atomic absorption spectrophotometry (CV-AAS). This method ensures precise quantification by minimizing interferences typical in other analytical techniques like ICP-MS. Sample preparation is crucial; it includes filtration, dilution, and sometimes pre-concentration to ensure accurate results.
The ASTM D5673 standard specifies strict procedural controls to validate the method's accuracy and precision. Laboratories must perform blank checks, replicate samples, and conduct recovery studies to demonstrate method robustness. This ensures that reported values are reliable and can be trusted for regulatory compliance and research applications.
