👉 The main fumes emitted from various industrial processes and combustion sources typically include volatile organic compounds (VOCs) such as benzene, toluene, and xylene, which are common solvents used in manufacturing and degreasing. Additionally, particulate matter like carbon monoxide (CO), nitrogen oxides (NOx), and fine particulates (PM2.5 and PM10) can be significant, especially from burning fuels or high-temperature processes. These fumes pose health risks due to their potential to cause respiratory issues, neurological effects, and long-term chronic conditions, making air quality monitoring and control crucial in industrial settings.
