How are Toxicants Measured in Environmental Matrices?
The measurement of toxicants in environmental matrices involves sampling and analytical techniques. Some common methods include:
Air Sampling: Techniques like high-volume air sampling and passive sampling are used to measure airborne pollutants. Water Sampling: Grab sampling and composite sampling are typical methods for assessing contaminants in water bodies. Soil Sampling: Systematic grid sampling and random sampling help evaluate soil contamination. Biological Monitoring: This involves analyzing biological tissues to assess exposure levels in organisms.
Advanced analytical techniques such as chromatography and spectroscopy are employed to detect and quantify toxicants.
