Description:

This illustration explains how air pollution comes from natural, area, stationary, and mobile sources. It shows major contributors like factories, vehicles, cities, wildfires, and volcanoes. The image highlights primary pollutants (like CO, SO₂, NO, and PM) released directly into the air, and secondary pollutants (like NO₂, H₂SO₄, and HNO₃) formed through chemical reactions in the atmosphere. It’s a valuable tool for understanding air pollution, perfect for environmental studies, climate discussions, and policy planning. Great for educators, researchers, and decision-makers focused on sustainability.
