One of the simplest natural resources is photosynthesis, which produces carbon dioxide. The resulting emissions undergo many types of physical and chemical transformations and contribute to a wide range of health and environmental impacts. . According to the World Health Organization, air pollution is a major environmental health hazard and is estimated to cause about two million premature deaths. around the world annually. including deterioration of air quality, toxic stress on human health and ecosystems, formation of photooxidants (smog), depletion of the spherical ozone layer (O3), climate change, deterioration of air resources, noise. 1.2 Objectives. A comparison between the values of PM2.5 measured from Air U devices in terms of: • The height of the point above sea level. • The distance and proximity to the main streets. • It is close to industrial areas.
