The air pollution is currently the biggest health risk and monitoring the air we breathe is more important than ever. Pollution with particulate matter PM2.5 and PM10 can cause serious environmental problems (change in cloud formation, contribution to global warming, the change in the radiation balance of the Earth and reduced visibility) and affects human health (cardiovascular disease, pregnant women, the elderly, diabetic and those with lung disease). Occupational exposure to particulate matter is associated with respiratory health in the work environments. This paper aims to determine the pollution with PM2.5 and PM10 in an industrial working environment.
