Wildfires increasing air pollution in Northwest<\/p>\n\n\n\n

BOTHELL, Washington \u2014 A growing number of wildfires has increased particulate air pollution over the last several decades in the Northwest, researchers at the University of Washington Bothell report.<\/p>\n\n\n\n

足彩app哪个是正规的 increase is in contrast to the downward trend seen in the rest of the country, which has gotten consistently cleaner due to regulations under the U.S. Clean Air Act.<\/p>\n\n\n\n

足彩app哪个是正规的 findings are reported in the paper \u201cUS particulate matter air quality improves except in wildfire-prone areas.\u201d It was published Monday in the journal Proceedings of the National Academy of Sciences of the United States of America. 足彩app哪个是正规的 authors are Crystal McClure, a University of Washington doctoral student in Atmospheric Science, and Dan Jaffe, University of Washington Bothell professor in Environmental Chemistry.<\/p>\n\n\n\n

An increase in fires and smoke in the Northwest has been predicted in the future due to climate change. But the McClure and Jaffe study demonstrates that these effects are here today. \u201cThis is another nail in the coffin that climate change is real and is happening now,\u201d Jaffe said. \u201cIn the future, we will be dealing with more and more smoke in the western United States as a result of climate change.\u201d<\/p>\n\n\n\n

Northwest wildfires have been on the rise since the mid-1980s and are a major source of PM2.5, which poses a significant health hazard. On many days these fires generate air pollution levels that are unhealthy and well above the Environmental Protection Agency (EPA) daily standard for PM2.5. This fine particulate matter, with particle diameters less than 2.5 microns, is hard to detect. A micron is one-millionth of a meter. A human hair is 50-75 microns in diameter.<\/p>\n\n\n\n

足彩app哪个是正规的 analysis focused on the 98th percentile of days, which equates to the seven highest days each year. 足彩app哪个是正规的 researchers found that these seven highest days are getting worse.<\/p>\n\n\n\n

足彩app哪个是正规的 researchers analyzed data from a national network known as IMPROVE, the Interagency Monitoring of Protected Visual Environments. This network has tracked particulate concentrations for more than 30 years at over 160 sites around the country.<\/p>\n\n\n\n

Funding for the research was provided by the National Science Foundation Grant 1447832 and National Oceanic and Atmospheric Administration Grant NA170OAR431001.<\/p>\n\n\n\n
