Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

Thus, it is important to identify and quantify the most important human-produced sources of VOC emissions to effectively mitigate air pollution and improve human health, the authors said. Even so, lotions, paints and other products contribute about as much to air pollution as does the transportation sector.
