How does lead pollute the air? Mainly through the cars emissions that use gasoline with tetra-ethyl lead and the emissions of particulate matter resulting from the extraction, transport, manipulation and storage of lead minerals.
Environmental Effects: Lead can also be deposited on leaves of plants, presenting a hazard to grazing animals. Sources: In the past, motor vehicles were the biggest source of lead. But since leaded gasoline has been phased out, lead emissions have decreased by about 98 percent. Today, metal processing is the biggest source of atmospheric lead. The highest air concentrations are found in the vicinity of ferrous and nonferrous smelters and battery manufacturers. Copyright Â© 2017 cleanairtrust.org.
