The largest anthropogenic source of CO in the United States is vehicle emissions ii. Health Impacts of Sulfur Dioxide Emissions. Airpollution in the form of sulfur dioxide can have detrimental effects on human health. Such effects include breathing problems, particularly in asthmatics, whereas short-term exposure canleadto chest tightness and coughing and wheezing. Sourcesof NOx Pollution.
