Monitoring aerosols involves measuring their concentration, size distribution, and chemical composition. Techniques include: - Gravimetric analysis, where air samples are collected on filters and weighed. - Optical methods, using instruments like nephelometers and photometers to measure light scattering and absorption by particles. - Chemical analysis, employing methods like mass spectrometry and chromatography to identify specific compounds in aerosols. - Remote sensing, using satellites and ground-based sensors to monitor aerosol distribution on a larger scale.
