Mercury in the environment can originate from both natural and human-generated sources, including volcanic activity, wildfires, combustion processes, industrial emissions, and the use of elemental mercury in chemical applications. Due to mercury’s ability to persist and, in certain forms such as methylmercury, bioaccumulate in the environment, accurate measurement at very low concentrations is important for environmental monitoring and risk assessment.

Traditional mercury air sampling methods, including NIOSH 6009, may present challenges when evaluating low-level mercury concentrations due to potential background mercury present in commonly used sorbent media. These challenges can impact data quality, particularly for applications such as soil gas monitoring where low flow rates and limited sample volumes require highly sensitive analytical techniques.

Eurofins Environment Testing provides ultra-low concentration mercury and dimethyl mercury analysis for air, soil gas, and emission source samples. Our advanced analytical capabilities support accurate detection and measurement of mercury species in complex environmental settings, helping clients generate reliable data for investigations, monitoring programs, and regulatory requirements.
