In environmental analysis, chromatography is used to?

• A. Measuring rainfall and humidity.
• B. Monitoring pollutants in air, water, and soil.
• C. Analyzing food additives in packaging.
• D. Determining mineral content in soil.

Answer: (B)

Chromatography shines in environmental analysis because it can separate and identify the diverse chemicals present in air, water, and soil, even when they occur at very low levels. By separating pollutants from the complex environmental matrix, analysts can accurately quantify them using detectors, often applying gas chromatography for volatile compounds or liquid chromatography for nonvolatile ones, sometimes coupled with mass spectrometry for precise identification. This capability is essential for monitoring contaminants such as pesticides, solvents, hydrocarbons, and industrial chemicals to assess pollution and regulatory compliance. Other options describe measurements that aren’t chemical separations or are focused on different fields, and mineral content in soil is typically measured by elemental techniques rather than chromatography.
