{"title":"Wildfire Significance within the San Francisco Bay Area’s Air Quality","authors":"S. Hashimoto","doi":"10.5070/bs326157103","DOIUrl":"https://doi.org/10.5070/bs326157103","url":null,"abstract":"Due to the increase in frequency and severity of wildfires in the San Francisco Bay Area, wildfire smoke has become a significant public health hazard linked with lung morbidity and increased mortality in exposed populations. Wildfire smoke consists of many types of particles, each with its own set of adverse effects. This study focuses on particulate matter smaller than 2.5 microns, or PM 2.5, one of the main contributors to adverse health effects, especially to the pulmonary and cardiovascular systems. In particular, we examine trends in 21 years of publicly available data from the Environmental Protection Agency on PM 2.5 air pollution by county by comparing PM 2.5 levels in the wildfire season months (May through October) to the rest of the year. Upon initial review, our findings may seem counterintuitive; on the three examined features of the dataset (mean, median, and maximum), the non-wildfire season generally yielded higher concentrations of mean and maximum PM 2.5 than the wildfire season. However, over time, the gap between the seasons has shrunk, which we propose is partially due to the PM 2.5 maximums driven by recent wildfires. Although the historic gap of PM 2.5 levels between wildfire and non-wildfire should be explored, the acute maximums offer a compelling climate and public health threat to the San Francisco Bay Area region as a whole. Given the severe public health consequences of exposure to PM 2.5 and wildfire smoke, we urge policy makers to take additional preventative and mitigative action during and in preparation for annual wildfire seasons.

The western United States has seen consistent and rapid increases in wildfire activity since the 1980s, characterized by a rise in the frequency, severity, size, and total burned area associated with wildfires. California recognizes emerging wildfires as one of the significant threats to be expected under climate change;1 aggregate fire indices have risen by 20% following temperature increases and precipitation decreases in autumn over the last four decades.2 California wildfires from the last five years (Carr, Camp, Lightning Complex, and Dixie) highlight the necessity of wildfire prevention and mitigation. Wildfire smoke, in particular, has been a public health risk for vulnerable populations and is projected to become increasingly severe amidst high emissions climate change scenarios.3 Smoke ","PeriodicalId":8753,"journal":{"name":"Berkeley Scientific Journal","volume":"139 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86621174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
