Humans have impacted Earth's atmosphere for more than 700 years, far longer than the Industrial Revolution and much longer than initially believed, according to a new study.
While waste disposed of in nature remains at the same place, air pollution does not stop at national borders. The wind can carry exhaust fumes or...
The research findings were published on Monday, April 12, in the Proceedings of the National Academy of Science. The researchers examined airborne microplastics, which have been far less studied than plastic in oceans and rivers. Researchers said human pollution has led to a global plastic cycle similar to natural processes such as the carbon cycle with plastic moving through the atmosphere, oceans and land. The result is the “plastification” of the planet, said one scientist. Lead author Janice Brahney, assistant professor of natural resources at Utah State University, and Natalie Mahow...

Published Monday, April 12, in the journal Proceedings of the National Academy of Sciences, the study also found that sea spray and agricultural runoff generated 10 and five percent of atmospheric microplastics, respectively. Meanwhile, in hotspots for microplastic sources and accumulation, microplastics lingered in the air for up to 6.5 days. Lead author Janice Brahney, an assistant professor from the department of watershed sciences at Utah State University, said she and her colleagues wanted to determine how microplastics were moving through the environment, as well as how far.
