EN 16619 Pesticides and POPs in Surface Water Test
The European Standard EN 16619 specifies methods for determining pesticides, including persistent organic pollutants (POPs), in surface water. This testing is crucial for ensuring compliance with environmental regulations and safeguarding public health. The standard provides a robust framework for the analysis of both known and emerging contaminants.
Under this standard, surface water samples are collected from various sources such as rivers, lakes, canals, and other bodies of water. Samples must be representative of the water body being tested to ensure accurate results. Typically, these samples undergo rigorous preprocessing steps including filtration, extraction, and derivatization where necessary.
The analytical techniques used in EN 16619 include gas chromatography-mass spectrometry (GC-MS), liquid chromatography-tandem mass spectrometry (LC-MS/MS), and other advanced spectroscopic methods. These instruments are selected based on the specific compounds being targeted, their volatility, polarity, and stability.
For pesticides, GC-MS is often used due to its high sensitivity and ability to differentiate between closely related compounds. For POPs like dioxins and furans, LC-MS/MS provides better selectivity and lower detection limits. The standard also includes detailed acceptance criteria for the detection of both target and non-target compounds.
The testing process is divided into several stages: sample collection, storage, transport to the laboratory, extraction or derivatization if necessary, instrumental analysis, data processing, and finally reporting results according to EN 16619 guidelines. Each step must be meticulously documented to ensure reproducibility and traceability.
Quality assurance and quality control (QA/QC) play a pivotal role in maintaining the integrity of these tests. Internal audits, proficiency testing programs, and regular calibration checks are integral parts of our quality management system. This ensures that all results meet the stringent requirements set forth by EN 16619.
