Summary

Researchers characterized particulate matter generated by burning common plastic types, finding that it contains environmentally persistent free radicals and reactive oxygen and chlorine species at levels with significant implications for air quality and human health near open plastic burning sites.

Burning plastic waste releases massive amounts of atmospheric particulate matter (PM), but its chemical composition and health-related properties are largely unelucidated. Here we characterize chemical composition of PM generated from burning common types of plastics and quantify reactive oxyg...
