Heavy Metal
Analysis
by ICP-OES
Heavy metal analysis using Inductively Coupled Plasma (ICP) testing is a sophisticated method for detecting and quantifying trace levels of heavy metals in various samples such as water, soil, food, air and industrial materials. ICP testing involves introducing a sample into an inductively coupled plasma, where it is atomized and ionized. The resulting ions are then analyzed using mass spectrometry or optical emission spectroscopy to identify and measure the concentrations. The precision and sensitivity of ICP testing make it a preferred choice for detecting heavy metals at very low concentrations, which is crucial for assessing potential health risks and environmental impacts.Heavy Metals analysis typically includes five main elements due to them being of significant toxicological concern compared to the other elements. These five are Mercury, Lead, Chromium, Cadmium, and Arsenic. Slightly less common, but regularly analysed are Copper, Nickel and Zinc.
Analysis of these metals is required due to acute and chronic toxicity which can occur from very low concentrations levels. Mechanisms are debated for each individual element’s toxicity but there is a general conclusion that the toxicity of heavy metals is due to the fact they displace original metals from their natural binding sites, causing the cells to malfunction which eventually leads to toxicity.
For instance in drinking water the presence of heavy metals can pose serious health hazards and in industrial operations heavy metal analysis helps in quality control and ensuring that materials meet safety and regulatory standards. Additionally, ICP testing supports research and environmental monitoring by providing accurate data on contamination levels, which is essential for developing effective remediation strategies and maintaining compliance with environmental regulations.
