Toxicological screening of PM2.5 from wildfires involving different biomass fuels

Environmental Pollution, Год журнала: 2025, Номер unknown, С. 125887 - 125887

Опубликована: Фев. 1, 2025

Wildfires are becoming increasingly frequent and severe, particularly in Southern Europe. In addition to their immediate environmental socioeconomic impacts, wildfires release significant amounts of particulate matter (PM), which poses serious health ecological risks. Gaseous (CO CO2) PM2.5 samples were collected directly from smoke plumes, the modified combustion efficiency (MCE) was calculated characterise conditions. This study aims assess cytotoxicity, mutagenicity ecotoxicity during Portugal, with a focus on how varying biomass types conditions impact these effects. Ecotoxicity assessments using Aliivibrio fischeri showed that ranged toxic extremely toxic, mixed vegetation burns (eucalyptus, acacia, ferns) exhibiting highest toxicity levels. Cytotoxicity tests human lung epithelial cells (A549) demonstrated dose-dependent decrease metabolic activity no membrane damage, while assays identified direct-acting mutagens smouldering acacia debris combustion, specifically inducing frameshift mutations Salmonella typhimurium strain TA98. Root growth inhibition toxicity, some samples, instead, promoting probably due nutrient content. Peroxidase responses indicated that, at higher concentrations, enzyme function could be reduced if defence mechanisms overwhelmed or stimulated high These findings highlight complex toxicological profiles wildfire PM, emphasising need for further research.

Rising wildfire risks in Europe fuelled by global warming

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 3, 2025

Recent extreme wildfires worldwide have raised concerns about the accelerating impacts of climate change. Assessing socioeconomic is challenging due to uncertainties in risk drivers and observational records. Here, we implement a high-resolution data modelling framework quantify fire season length, population exposure weather, wildfire economic damage Europe for range global warming scenarios. Climate change expected lengthen across Europe, particularly southern regions already prone fire-conducive weather. While south faces extended periods high danger, central northern will be increasingly exposed adverse weather conditions. Present direct damages €2.4 billion per year could nearly double with 3°C or more. Mediterranean bear highest burden, annual maximum reaching 5–10% their regional economy. Our findings advocate stringent mitigation, fire-resistant ecosystems, resilient communities near fire-prone areas.

Global health burden from acute exposure to fine particles emitted by fires

Acute exposure to emissions from fires presents a significant and immediate threat human health. Inhalation of wildfire smoke other pollutants can lead various health issues, including respiratory cardiovascular problems. Our study uses the SILAM chemical transport model, integrated with IS4FIRES fire information system, assess population fire-related PM2.5, along burden all-cause, respiratory, deaths. results show that while population-weighted all-source PM2.5 has declined in Europe high-income North America, fire-PM2.5 increased significantly Eastern Central Europe, Tropical Latin sub-Saharan Africa. Extreme events have tripled globally since 1990s, more than half global experiencing minimum perpetual occurrence (least 1% fire-PM_2.5 for 50 instances 3 consecutive days calendar year) 2010–2018. contributed 99,000 (95% CI − 55,000–149,000) all-cause deaths annually 2010-18, disease burdens, particularly findings highlight escalating risks emissions, emphasizing urgent need mitigation strategies as becomes growing contributor air pollution-related mortality.

Wildfire events in the US are becoming more frequent and intensive due to climate change. Fire smoke can significantly contribute ambient PM2.5 (PM2.5, particles smaller than 2.5 µm diameter) levels alter its chemical composition. An emerging body of literature has linked COPD mortality episodic wildfire exposure, but studies on effect long-term fire exposure is lacking. We aimed evaluate how affect among elderly people explore spatial variability this effect. investigated all aged 65-100 years contiguous United States using Medicare National Death Index data from 2008 2016. identified three subregions based risk indicate differences exposure. used time-varying Cox Proportional Hazards Models mortality. found that strongly associated with increase 1 µg/m3 was a 9.2 % (95 CI: 8.8 %-9.7 %). Specifically, A may deaths by 40.4 %, 9.6 3.9 low, moderate, high areas, respectively. Our study reveals contributes people. Notably, those living regions relatively lower appear vulnerable. Therefore, prevention should be emphasized areas not typically active.

Strong reduction in near-surface turbulence due to aerosols in South and East Asia

Опубликована: Апрель 30, 2025

Abstract Absorbing and scattering aerosols influence the vertical temperature profile can lead to a shallower boundary layer potentially enhanced surface air pollution. Using regional chemistry-climate model validated against >1000 quality monitoring stations, we show that absorbing black carbon (BC) reduce near-surface turbulence height through aerosol-radiation interactions (ARI). While ARI due total PM 2.5 concentrations 25,000–27,000 annual excess deaths in each of Northern India Eastern China, BC have modest impact on because its ability for self-lofting precipitation affecting wet scavenging. However, over India, strongly increase number days with combined high relative humidity, which is dangerous human health. These results highlight multitude indirect impacts from individual aerosol species need be considered achieve efficient mitigation
