Air Pollution Sources
- Natural sources of air pollution include volcanic eruptions, wildfires, dust storms, and pollen.
- Anthropogenic sources of air pollution are responsible for the majority of air pollution and include:
- Fossil fuel combustion from vehicles, industrial activities, and power generation.
- Industrial processes such as mining, smelting, and cement production.
- Agricultural activities including livestock, fertilizer use, and pesticide application.
- Waste management practices like landfills and incineration.
Air Quality Monitoring Techniques
Active Monitoring
- Active monitoring involves sampling and analyzing air pollutants to determine their concentration.
- Sampling methods used in active monitoring include filter-based sampling, sorbent-based sampling, and impactor-based sampling.
- Analytical techniques used in active monitoring include chromatography, spectroscopy, and gravimetry.
Passive Monitoring
- Passive monitoring involves using devices that absorb or collect air pollutants over time to determine their concentration.
- Diffusive sampling methods used in passive monitoring include badges and tubes.
- Bioindicator organisms like lichens, mosses, and plants can also be used to monitor air pollution through passive monitoring.
Remote Sensing
- Remote sensing involves using sensors and satellites to monitor air pollution from a distance.
- Satellite imagery can be used to measure aerosol optical depth and particulate matter concentrations.
- Lidar (Light Detection and Ranging) technology can be used to create vertical profiles of aerosols and measure aerosol backscatter coefficients.
