main pollutant in rainwater

The main pollutant in rainwater is typically particulate matter, such as dust, dirt, and soot, that is picked up from the atmosphere. However, rainwater can also contain other pollutants, such as chemicals and heavy metals, that have been released into the air through human activities, such as industrial processes and transportation. These pollutants can have harmful effects on human health and the environment if they are not properly managed and controlled.
