Gas Chromatography (GC) is widely used in environmental analysis to detect and measure pollutants and chemicals in air, water, and soil. Here are the common applications:
1. Air Quality Monitoring
- Detects volatile organic compounds (VOCs) in the atmosphere.
- Measures industrial emissions, car exhaust, and indoor air pollutants.
- Helps monitor airborne toxic chemicals like benzene, toluene, and formaldehyde.
2. Water and Wastewater Analysis
- Detects pesticides, herbicides, and organic pollutants in drinking water or rivers.
- Monitors industrial effluents for hazardous compounds.
- Measures chlorinated solvents and other volatile contaminants.
3. Soil and Sediment Testing
- Identifies pesticide residues and hydrocarbons in soil.
- Monitors contaminated sites to assess cleanup efficiency.
4. Detection of Persistent Organic Pollutants (POPs)
- Detects PCBs (polychlorinated biphenyls), dioxins, and DDT residues.
- Helps track long-lasting pollutants in the environment.
5. Food and Environmental Safety
- Detects residual solvents or contaminants in food and beverages.
- Monitors environmental exposure of harmful chemicals to humans and wildlife.
In short:
GC is used in environmental analysis to detect, quantify, and monitor pollutants in air, water, soil, and food, helping to ensure environmental safety and compliance with regulations.
