EN 1483 Mercury Content Testing in Drinking Water
The European Standard EN 1483 specifies the methods for determining the mercury content in drinking water. This service ensures that the levels of mercury do not exceed the limits set by regulatory bodies to protect public health and environment.
Mercury is a toxic heavy metal known to have adverse effects on human health, particularly on the nervous system. In high concentrations, it can cause severe damage leading to chronic poisoning with symptoms such as memory loss, tremors, and cognitive decline. Given these risks, accurate testing of mercury content in drinking water is critical.
The standard covers both total and speciated mercury measurements. Total mercury includes all forms present in the sample, while speciation separates methylmercury from inorganic mercury species like mercuric chloride or mercurous chloride. Methylmercury is particularly toxic due to its bioaccumulation potential and high affinity for binding sites in tissues.
The testing process involves several steps:
- Sampling: Samples are collected using appropriate containers made of materials that do not leach mercury or other contaminants into the sample.
- Sample preparation: Depending on the type of analysis, samples may be filtered, digested, and diluted as necessary to ensure accurate readings.
- Instrumentation: The test typically employs atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS), both recognized for their high sensitivity and accuracy.
The results are reported according to the standard's guidelines, providing a quantitative measure of mercury content. Compliance with this testing ensures adherence to international standards such as ISO 17025 for laboratory accreditation.
| Test Method | Description |
|---|---|
| Atomic Absorption Spectroscopy (AAS) | An older technique still used for its simplicity and cost-effectiveness. It measures the absorption of light by free atoms in a sample vaporized into a flame. |
| Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | A more modern, highly sensitive method that ionizes the sample and uses mass spectrometry to identify and quantify the mercury isotopes present. |
The acceptance criteria for this testing are stringent, ensuring public health safety. The limit of detection (LOD) is set at 0.1 μg/L, which is below the World Health Organization's guideline value of 13 μg/L. Samples exceeding these limits require immediate attention and potential remediation actions.
Our laboratory adheres to EN 1483 by employing experienced staff, state-of-the-art equipment, and rigorous quality control measures. This ensures that our clients receive reliable results that meet regulatory requirements.
