This study investigates the characteristics of visibility, PM_2.5 concentration, and its components, as well as their effects on extinction, and oxidative potential (OPv) through observational data and the WRF-Chem model within the context of these emission reduction strategies. Analysis of data collected during the spring and summer of 2019 revealed that PM_2.5 concentrations were significantly higher in spring (48 µg/m³) compared to summer (35 µg/m³), primarily due to emissions related to heating and unfavorable meteorological conditions. While average visibility showed slight variation between the seasons (21.53 km in spring versus 20.99 km in summer), OPv was markedly elevated in summer. The chemical composition of PM_2.5 was found to exert a more substantial influence on visibility and OPv than mass concentration alone. Visibility appeared to be strongly influenced by relative humidity (RH), mainly when RH ≤ 60%. Conversely, PM_2.5 concentrations significantly affected visibility within the range of 40% ≤ RH &lt; 60%. Nitrate contributed the most to the extinction coefficient (37%), followed by organic carbon (24%) and sulfate (15%). The contribution rates of various chemical components to atmospheric extinction were significantly altered depending on visibility levels. Secondary components were identified as the principal source of atmospheric extinction, comprising 41% of total extinction, and were also the predominant contributors to OPv. The findings of this study lay the groundwork for the development of more effective air quality management strategies in Beijing.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"18 8","pages":"2343 - 2356"},"PeriodicalIF":2.9,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dieldrin, chlordane, heptachlor, and chlorpyrifos, which are effective termiticides, have been banned because of their high toxicity. Neonicotinoids, pyrethroids, phenyl pyrazoles, and triazoles have been used as alternatives to termiticides in indoor environments. However, despite numerous studies showing that farm-applied pesticides contaminate house dust, the health risks to humans from indoor termiticides remain unclear. We collected house dust and indoor air samples from 37 and 7 houses, respectively, to investigate the indoor termiticide contamination levels. The minimum margin of exposure to fipronil was 173, indicating that fipronil posed the highest risk among the targeted 28 compounds in indoor environment. The mean concentrations of alternative termiticides in house dust and air samples ranged from 1,126 ng g^− 1 (cyproconazole) to 5,356 ng g^− 1 (MGK-264) in thirty-seven houses and 0.08 ng m^− 3 (acetamiprid) to 34 ng m^− 3 (MGK-264) in seven houses, respectively. These results are comparable to the pesticide concentrations in houses close to farms where pesticides were applied, and are higher than atmospheric pesticide concentrations in oceans. Therefore, houses sprayed with termiticides may be as contaminated as agricultural environments where farmers apply substantial quantities of pesticides. The main route of exposure was air inhalation for fipronil, and both air inhalation and house dust ingestion for triazoles and potentiators. Establishment of regulations and development of decontamination methods are needed for indoor contamination of termiticides. Floor cleaning may be effective to remove termiticides that are ingested mainly through the house dust pathway.</p>\u0000 </div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"18 8","pages":"2333 - 2341"},"PeriodicalIF":2.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a set of low-cost sensors, the present study investigated the in-cabin PM exposure of dumper, shovel and drill machine operators and compared it with the cabin outside PM concentration in a large opencast mine where a large number of HEMMs are deployed. The results revealed that the drill operators were exposed to the highest in-cabin PM concentration (PM₁ = 190.98 ± 30.3 µg m⁻³, PM_2.5 = 281 ± 52.85 µg m⁻³, PM₁₀ = 1475.23 ± 915.42 µg m⁻³) followed by the exposures of shovel (PM₁ = 45.62 ± 24.28 µg m⁻³, PM_2.5 = 97.85 ± 51.10 µg m⁻³, PM₁₀ = 354.38 ± 219.69 µg m⁻³) and dumper operators (PM₁ = 42.08 ± 18.25 µg m⁻³, PM_2.5 = 90.38 ± 44.55 µg m⁻³, PM₁₀ = 331.05 ± 225.65 µg m⁻³). The exposure in the evening shift was 10% higher than exposure during the morning shift. The in-cabin PM concentrations while the dumper travelled on main haul road were ~ 2 times of the corresponding values when it travelled on the internal haul road. In addition to the outside concentration, the in-cabin PM levels are influenced by cabin ventilation (AC vs. non-AC), structural leakage, and door/window operation. AC cabins could reduce the PM exposure up to 40% (10% for non-AC cabins) than ambient mine environments. GLM explained 65–89% of PM concentration variability, with HEMM type and meteorological parameters as significant predictors. The health risk assessment indicates that all operators are exposed to non-carcinogenic health risks, as the Risk Quotient (RQ) values for each exceed the threshold of 1 (RQ &gt; 1). Notably, the drill operator is subjected to the highest non-carcinogenic risk, with an RQ value of 8. While, the Excess Lifetime Cancer Risk (ELCR) assessment for PM_2.5 exposure reveals potential carcinogenic risks among operators in two age groups. For the 18-year age group, the ELCR values range from 6.15 × 10⁻⁴ to 1.92 × 10⁻³, whereas for the 21 years and above age group, the values range from 5.13 × 10⁻⁴ to 1.60 × 10⁻³, indicating elevated cancer risk among 18 + age group of operators.

To evaluate the effectiveness of the four orange alert emergency measures in mitigating severe air pollution, this study employed the WRF-CMAQ air quality model to conduct numerical simulations. These simulations were based on the differences in industrial pollutant emissions under emergency measures. The analysis focused on air pollutant concentrations, including PM_2.5 and other pollutants, along with meteorological conditions, weather patterns, and air mass transport during the orange alert periods. Additionally, the study examined how emission reduction measures in Tangshan’s industrial affected PM_2.5 and other pollutant concentrations, and it assessed the effectiveness of the orange alert emission reductions. The results showed that the average PM_2.5 concentration was 0.74–5.01 times higher than that after the alert.

These pollutants and greenhouse gas were collected and measured through on-road experiments using a specifically designed portable emission measurement system (PEMS) on two testing routes. The results indicated significant variations in emission factors across vehicle and fuel types. Gasoline vehicles exhibited higher CO and CO₂ emission factors than their diesel and CNG counterparts.

Among all vehicle categories, light-duty gasoline trucks (LDGTs) and medium-duty gasoline passenger vehicles (MDGVs) had the highest CO emissions (10.3 g km^− 1 and 8.0 g km^− 1, respectively). Heavy-duty diesel passenger vehicles (HDDVs) emitted the most NO_x (10.1 g km^− 1) and CO₂ (1109.4 g km^− 1).

The limited availability and distribution of ground-based measurements hinder long-term studies on the impacts of air pollution in Bangladesh. Therefore, in this study, global estimates of monthly PM2.5 developed by Washington University were used to analyze the spatiotemporal distribution and variability of PM2.5, trends, health risk (HR), control zones, and potential source contribution function (PSCF) in Bangladesh from 2001 to 2020. The 20-year average spatial distribution shows PM_2.5 hotspots across Bangladesh, particularly in the urban areas of Dhaka, Mymensingh, Chittagong, Barisal, Khulna, Rajshahi, and Rangpur, with higher pollution in the winter than in other seasons. In winter, PM_2.5 ranged from 55.12 to 159.42 µg/m³ across 64 cities in Bangladesh, which is 11 to 32 times higher than the World Health Organization Air Quality Standards (WHOAQS; annual mean: ≤ 5 µg/m³) and 4 to 11 times higher than the Bangladesh National Ambient Air Quality Standards (BNAAQS; annual mean: ≤ 15 µg/m³). Moreover, PM₂.₅ levels significantly increased in 63 cities across Bangladesh, with rates ranging from 0.54 to 1.38 µg/m³/year between 2000 and 2020. PM₂.₅ components in Bangladesh show an increasing trend for Sea Salt (SS), Organic Carbon (OC), Sulfate (SO₄), Black Carbon (BC), and Nitrate, except for Dust, which exhibits a negligible decreasing trend.

The HR assessment showed that the percentage of extremely high-risk areas in Bangladesh rose significantly from 14.57 to 39.29% between 2001 and 2020. Finally, PSCF analysis shows that air quality in Bangladesh is mainly affected by external sources of PM_2.5 originating from the Indo-Gangetic Plain (IGB), India, Nepal, Bay of Bengal, Sri Lanka, Gulf of Mannar, Arabian Sea, and Laccadive Sea, with the strongest impact in the winter, followed by spring, autumn, and summer.

A systematic review of 212 studies from 2015 to 2024 was conducted, focusing on solid fuel combustion for cooking and its health effects. Bibliometric analysis revealed prominent research themes, including environmental monitoring, toxicology, maternal and child health, and public health impacts of air pollution. Statistical analysis, including forest plots, funnel plots, and heterogeneity tests, was performed to assess the effect sizes and variability across studies. Health analysis was conducted using MS Excel and R software. The results showed significant associations between pollutant exposure and various health outcomes. PM_2.5 and PM₁₀ were strongly linked to cardiovascular diseases, chronic obstructive pulmonary disease, and lung cancer. CO exposure was associated with adverse outcomes, while NO₂ and SO₂ had modest but harmful impacts. Children exposed to PM_2.5 had an increased risk of acute respiratory infections. Mental health effects, such as cognitive decline, depression, anxiety, and stress, were also associated with pollutant exposure. The prevalence of diseases increased with age, peaking in the 55–65 age group. Switching from solid fuels to cleaner alternatives such as LPG and electric cooking can significantly reduce indoor air pollution, and associated health risks when used safely, although proper handling and safety measures are essential to mitigate potential hazards linked to LPG use.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"18 7","pages":"2077 - 2095"},"PeriodicalIF":2.9,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
