Study: Increased soot linked to nearly 10K early deaths

摘要

Reversing a long-term trend, overall ambient air levels of fine particulate matter edged up almost 6% in someparts of the United States between 2016 and 2018, two Carnegie Mellon University researchers conclude in a newly published paper.The study links the increase in particulate matter, also known as soot, to 9,700 additional premature deaths lastyear and $89 billion in associated economic damage.The health implications are "significant," Karen Clay, a Carnegie Mellon economist who led the study, said in anews release. "The number of deaths and the damages highlight the importance of air pollution as an importantand timely policy issue."
