Determination of Pesticides in Water by GC-MS: EN ISO 14403 Testing Services

EN ISO 14403 is an international standard that outlines the requirements for determining pesticides in water using Gas Chromatography-Mass Spectrometry (GC-MS) testing. This standard is widely adopted by laboratories worldwide and is recognized as a benchmark for ensuring the accuracy and reliability of pesticide detection in water samples.

Legal and Regulatory Framework

The determination of pesticides in water is regulated by various national and international laws, including:

  • European Union Directives: The EUs Water Framework Directive (2000/60/EC) and Drinking Water Directive (98/83/EC) set strict limits for pesticide residues in surface and groundwater.

  • World Health Organization (WHO): WHO guidelines provide recommendations for pesticide residue levels in drinking water, taking into account their toxicological properties and potential health risks.

  • United States Environmental Protection Agency (EPA): The EPA regulates pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and sets Maximum Contaminant Levels (MCLs) for pesticide residues in drinking water.

    • International and National Standards

    EN ISO 14403 is based on the International Organization for Standardization (ISO) standard, which provides a framework for laboratories to follow when conducting GC-MS testing. This standard is adapted by national standards bodies, such as:

  • British Standard (BS): BS EN ISO 14403

  • American Society for Testing and Materials (ASTM): ASTM D7365

  • Turkish Standards Institution (TSE): TSE EN ISO 14403

    • Standard Development Organizations

    The development of standards, including EN ISO 14403, involves collaboration between national and international organizations. Key players include:

  • International Organization for Standardization (ISO)

  • European Committee for Standardization (CEN)

  • National Standards Bodies: Such as DIN (Germany), AFNOR (France), and BSI (UK)

    • How Standards Evolve

    Standards, including EN ISO 14403, are subject to revision and update as new technologies and methodologies emerge. This ensures that testing methods remain relevant, accurate, and reliable.
