Atomic Absorption Spectroscopy (AAS) is widely used in environmental monitoring to detect and measure metals in water, soil, and air. Here’s how it works simply:
- Water Testing:
AAS measures toxic metals like lead, mercury, cadmium, and arsenic in drinking water, rivers, lakes, and industrial effluents to ensure they are within safe limits. - Soil Analysis:
Soil samples from farms, industrial sites, or contaminated areas are tested for metals like copper, zinc, and nickel. This helps assess soil health and contamination levels. - Air and Dust Monitoring:
Metals in air particulate matter or dust can be analyzed using AAS after collecting and preparing the samples. This is important near factories, mines, or traffic-heavy areas. - Regulatory Compliance:
Industries use AAS to monitor waste discharge and emissions to meet environmental laws and prevent pollution. - Research and Risk Assessment:
Scientists use AAS data to study how metals move through the environment and their effects on humans, animals, and plants.
In short, AAS helps detect harmful metals, prevent pollution, and protect human health and the environment.
