The Influence of Wildfire Smoke on Ambient PM_2.5 Chemical Species Concentrations in the Contiguous US

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 3, 2025

Wildfires significantly contribute to ambient air pollution, yet our understanding of how wildfire smoke influences specific chemicals and their resulting concentration in remains incomplete. We combine 15 years daily species-specific PM2.5 concentrations from 700 pollution monitors with satellite-derived PM2.5, use a panel regression estimate smoke's contribution the 27 different chemical species PM2.5. Wildfire drives detectable increases 25 out largest observed for organic carbon, elemental potassium. find that originating wildfires burned structures had higher copper, lead, zinc, nickel relative fires did not burn structures. is responsible an increasing share multiple species, some which are particularly harmful health. Using risk assessment approach, we wildfire-induced enhancement carcinogenic could cause population cancer risk, but these very small other environmental risks. demonstrate combining ground-monitored data can be used measure influence on exposures at large scales.

Wildfire risk management in the era of climate change

PNAS Nexus, Journal Year: 2024, Volume and Issue: 3(5)

Published: April 30, 2024

The August 8, 2023R Lahaina fire refocused attention on wildfires, public alerts, and emergency management. Wildfire risk is the rise, precipitated through a combination of climate change, increased development in wildland-urban interface (WUI), decades unmitigated biomass accumulation forests, long history emphasis suppression over hazard mitigation. Stemming tide wildfire death destruction will involve bringing together diverse scientific disciplines into policy. Renewed needed alerts community evacuations. Land management strategies need to account for impact change mitigation forest ecosystems. Here, we propose long-term strategy consisting integrating wider-scope land policies strategies, discuss new technologies possible breakthroughs.

The fastest-growing and most destructive fires in the US (2001 to 2020)

Science, Journal Year: 2024, Volume and Issue: 386(6720), P. 425 - 431

Published: Oct. 24, 2024

The most destructive and deadly wildfires in US history were also fast. Using satellite data, we analyzed the daily growth rates of more than 60,000 fires from 2001 to 2020 across contiguous US. Nearly half ecoregions experienced fast that grew 1620 hectares 1 day. These accounted for 78% structures destroyed 61% suppression costs ($18.9 billion). From 2020, average peak rate these doubled (+249% relative 2001) Western 3 million within 4 kilometers a fire during this period Given recent devastating wildfires, understanding is crucial improving firefighting strategies community preparedness.

Quantifying wildfire risk to the built environment in rural rangelands of the US Interior West

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1924)

Published: April 1, 2025

Fire increasingly conflicts with the built environment. The wildland–urban interface (WUI) describes areas where vegetation near environment increases wildfire hazard. In United States, attention concentrates on WUI in forested areas, but human populations are extending into rangelands. combination of expansion and woody plant encroachment might present novel challenges to management, especially given rural nature rangelands US, which extends response time emergency services. We use publicly available data describe abundance, distribution, type overall risk Most US Interior West (54%) occurs rangeland: majority is rangeland 4.3% that—over 1 million km 2 —is WUI. rural: 59% further than 10 from town tribal even more remote. Rangeland approximately twice as likely be degraded by non-WUI rangeland, suggesting that conventional fire suppression tactics for fuels insufficient or unsafe. Greater awareness help leverage community-level adaptive capacity against protecting lives property beyond urban/peri-urban zones.
