EN 27268 Nickel Content Testing in Drinking Water
The European Standard EN 27268: Nickel content of drinking water – Determination by atomic absorption spectrometry (AAS) is a crucial tool for ensuring the safety and quality of drinking water. This standard provides precise methodologies to measure nickel levels in potable water, which is essential for meeting regulatory requirements and protecting public health.
Nickel is an element that can be introduced into drinking water through various sources such as industrial processes, plumbing systems, and natural occurrences in water supplies. Excessive amounts of nickel in drinking water can pose significant health risks, including gastrointestinal irritation, liver and kidney damage, and even carcinogenic effects.
EN 27268 specifies the use of atomic absorption spectrometry (AAS), a highly sensitive analytical technique that quantifies trace metals like nickel with high precision. The standard outlines detailed procedures for sample preparation, calibration, instrumental settings, and data analysis to ensure accurate and reproducible results.
The testing process begins with proper sampling techniques to collect representative water samples from various sources within the distribution network. These samples are then prepared according to the prescribed methods in EN 27268 to minimize potential interferences and ensure accurate measurement of nickel content.
Once the sample is ready, it undergoes instrumental analysis using an atomic absorption spectrometer (AAS). The AAS instrument measures the absorption of light by free atoms in a flame or graphite furnace. This method provides high sensitivity and selectivity, making it ideal for detecting trace amounts of nickel in water.
The standard also includes detailed instructions on calibration standards and reference materials to ensure accurate results. Calibration is performed using known concentrations of nickel solutions, which are used to generate a calibration curve. This curve allows the conversion of measured absorbance values into actual nickel concentrations in the samples.
Acceptance criteria for nickel content in drinking water according to EN 27268 vary depending on the intended use and distribution system characteristics. For general potable water, the maximum allowable concentration is typically set at 100 μg/L (micrograms per liter) as specified by other international standards such as WHO Guidelines for Drinking-water Quality.
In addition to ensuring compliance with regulatory limits, nickel content testing plays a vital role in identifying potential sources of contamination and assessing the effectiveness of water treatment processes. Regular monitoring helps utilities maintain consistent water quality and address any issues promptly.
The importance of nickel content testing extends beyond mere compliance; it contributes significantly to public health and environmental protection. By adhering to standards like EN 27268, laboratories play a critical role in safeguarding the integrity of drinking water supplies across Europe and ensuring that consumers receive safe and high-quality potable water.
Accurate nickel content testing is particularly important for utilities with extensive distribution networks or those sourcing water from multiple sources. Continuous monitoring allows operators to detect any changes in nickel levels due to new construction, maintenance activities, or changes in raw water quality. Such information enables proactive management of water treatment processes and helps prevent potential health hazards associated with elevated nickel concentrations.
In summary, EN 27268 provides a robust framework for nickel content testing in drinking water, ensuring precision, reliability, and regulatory compliance. By following this standard, laboratories can contribute to maintaining the highest standards of public health and environmental safety.
