ISO 17993 Determination of Mercury in Water by Cold Vapor Atomic Absorption Spectroscopy (CVAAS) Laboratory Testing Service: A Comprehensive Guide

Standard-Related Information

The determination of mercury in water is a critical analytical task that requires precise measurement techniques to ensure the safety of human health and the environment. The International Organization for Standardization (ISO) has developed ISO 17993, which provides guidelines for the determination of mercury in water by Cold Vapor Atomic Absorption Spectroscopy (CVAAS). This standard is essential for laboratories conducting this testing service.

ISO 17993:

  • Published in 2004

  • Revised in 2019

  • Scope: Specifies a method for the determination of mercury in water using CVAAS.

  • Normative references:

    • ISO 10260 (1992)

    ISO 11885 (2017)

    ASTM D4916-09 (2015)

    EN 14803 (2009)

    Legal and Regulatory Framework

    The legal and regulatory framework surrounding mercury analysis in water is complex and varies by country. Some key regulations include:

  • The European Unions Water Framework Directive (2000/60/EC) sets limits for mercury in surface waters.

  • The United States Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 2 μg/L for mercury in drinking water.

  • The World Health Organization (WHO) recommends a provisional tolerable weekly intake (PTWI) of 0.1 μg/kg body weight per week.

    • Standard Development Organizations

    Standard development organizations play a crucial role in creating and maintaining standards like ISO 17993. Some key organizations include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

  • Turkish Standards Institution (TSE)

    • Evolution of Standards

    Standards evolve over time to reflect new technologies, methods, and regulations. ISO 17993 was revised in 2019 to incorporate new analytical techniques and improve the precision and accuracy of mercury determination.
