EN 1483 Mercury Determination in Surface Water
The European standard EN 1483 outlines a procedure for determining mercury concentrations in surface water. This method is crucial for environmental monitoring and compliance with regulatory standards, particularly in sectors such as water treatment, industrial discharge management, and waste management.
Mercury contamination in surface waters poses significant risks to human health and aquatic ecosystems. The determination of mercury levels helps in assessing the efficacy of pollution control measures and ensuring that surface waters meet safe drinking water quality standards. This service is essential for compliance with international regulations such as the European Union’s Water Framework Directive.
The method described in EN 1483 uses cold vapor atomic absorption spectrophotometry (CV-AAS) to measure mercury concentrations in surface water samples. The process involves several critical steps, including sample preparation and digestion, which ensure accurate detection of trace levels of mercury. Proper specimen handling is paramount; any contamination or improper handling can lead to inaccurate results.
The standard specifies that the sample should be filtered and digested with concentrated nitric acid before analysis. This step ensures that all mercury compounds are dissolved and available for detection. The digestion process must be conducted under controlled conditions to avoid loss of volatile forms of mercury. Once the digestion is complete, the solution is diluted according to the standard’s instructions.
The CV-AAS technique used in this service provides high sensitivity and specificity. It operates by converting gaseous elemental mercury into atomic vapor which is then excited with light from a hollow cathode lamp. The intensity of the emitted light is measured to determine the concentration of mercury present in the sample. This method is particularly effective for detecting low levels of mercury, making it ideal for environmental monitoring.
Ensuring accurate and reliable results is paramount when performing this type of analysis. Rigorous quality control measures are implemented at every stage of the process. These include regular calibration checks, use of certified reference materials, and participation in proficiency testing programs. Our laboratory adheres to strict ISO/IEC 17025 accreditation standards to ensure that all test results meet international quality assurance criteria.
Understanding the application context is essential for interpreting the results correctly. For instance, industrial discharges often introduce mercury into surface waters through effluents from chemical plants or mining operations. Proper determination of mercury levels allows for targeted mitigation strategies and ensures compliance with environmental regulations. Similarly, water treatment facilities need accurate mercury measurements to validate their processes.
Sample preparation is a critical aspect of this service. The type of sample (e.g., river water, lake water) can influence the method used. For instance, samples from areas near industrial sources may require more aggressive digestion techniques to ensure complete dissolution of all mercury compounds. Our team of experts ensures that each sample is prepared in accordance with EN 1483 guidelines.
