Abstract Effective abatement of air-pollution-induced health damages requires comprehensive understanding on the changing roles individual sources and cross-regional transport. Here, we estimate premature mortality attributable to specific source categories, precursor species, regions within mainland China. We find that marginal national deaths, dominated by PM2.5 exposure, have declined from 151,842 per 10% growth emissions in 2013 111,271 2020, would further 54,293 2035 following a carbon peaking neutrality pathway. The impacts certain species-category combinations grown including NOX industrial combustion off-road traffic. proportions cross-provincial burden remained stable around 50%. Provinces with net exporting deaths were intensively located north China while those importing south. Our findings highlight need for location-precursor/sector-specific strategy emission controls China’s public regulatory framework.

Linalool, a high-reactivity volatile chemical product (VCP) commonly found in cleaning products and disinfectants, is increasingly recognized as an emerging contaminant, especially indoor air. Understanding the gas-phase oxidation mechanism of linalool crucial for assessing its impact on atmospheric chemistry human health. Using quantum calculations computational toxicology simulations, we investigated transformation toxicity evolution under low high NO/HO2· levels, representing outdoor environments. Our findings reveal that can undergo novel mechanisms involving concerted peroxy (RO2·) alkoxy radical (RO·) modulated autoxidation, particularly emphasizing importance cyclization reactions indoors. This expands widely known RO2·-dominated H-shift-driven autoxidation proposes generalized leads to formation low-volatility secondary organic aerosol (SOA) precursors. Toxicological analysis shows over half (TPs) exhibited higher carcinogenicity respiratory compared linalool. We also propose time-dependent toxic effects TPs assess their long-term toxicity. results indicate strong emission coupled with slow consumption rates lead significant health risks environment. The highlight complex air concerns regarding persistent during cleaning, which involves use or other VCPs.

Pollutants in human milk are critical for evaluating maternal internal exposure and infant external exposure. However, most studies have focused on a limited range of pollutants. Here, 15 pooled samples (prepared from 467 individual samples) three areas the Yangtze River Delta (YRD) China were analyzed by gas chromatography quadrupole time-of-flight mass spectrometry. In total, 171 compounds nine types preliminarily identified. Among these, 16 compounds, including 2,5-di-tert-butylhydroquinone 2-tert-butyl-1,4-benzoquinone, detected first time. Partial least-squares discriminant analysis identified ten area-specific pollutants, 2-naphthylamine, 9-fluorenone, 2-isopropylthianthrone, benzo[a]pyrene, among Shanghai (n = 3), Jiangsu Province 6), Zhejiang 6). Risk index (RI) values calculated indicated that legacy polycyclic aromatic hydrocarbons (PAHs) contributed only 20% total RIs PAHs derivatives, indicating more attention should be paid to with various functional groups. Nine priority pollutants YRD The important 4-tert-amylphenol, caffeine, 2,6-di-tert-butyl-p-benzoquinone, which associated apoptosis, oxidative stress, other health hazards. results improve our ability assess risks posed milk.

Black carbon or elemental (EC) in the atmosphere plays an ambiguous role acute respiratory toxic effects. Here, we evaluate contribution of EC to short-term toxicity (including cytotoxicity and oxidative stress potency) fine particulate matter (PM2.5) on human tract using vitro airway organoids cell lines. The potency per unit mass, including char soot, is more than 2 orders magnitude lower that polycyclic aromatic hydrocarbons (PAHs), which are coemitted from incomplete combustion. contributes approximately 1 order less PM2.5 PAHs, despite its positive associations with PM2.5-induced (p < 0.0001). Furthermore, PAHs contribute 71.9 ± 12.2% 61.9 32.8% overall emitted typical burning solid liquid fuels, respectively, while significantly correlates content (r = 0.94, p 0.002). Hence, not a cause inducing toxicity, likely attributed PAHs. These findings provide causal evidence for understanding health risks associated exposure further benefit establishing efficient air pollution control policies.
