👉 The primary fumes emitted from many industrial processes and chemical reactions include volatile organic compounds (VOCs) such as benzene, toluene, and formaldehyde, which can cause respiratory issues and other health problems. Additionally, particulate matter like dust and aerosols, often containing heavy metals or other toxic substances, can be released. These fumes pose significant environmental and health risks, necessitating proper ventilation and safety measures in workplaces where such emissions occur.
