Cigarette combustion emits environmental tobacco smoke (ETS) that contains various pollutants, including volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons, and particulate matter with particles &lt; 2.5 μm in aerodynamic diameter (PM_2.5). Therefore, to assess the risk of passive smoking, it is necessary to determine the exposure levels to ETS compounds caused by passive smoking. However, it is difficult to assess exposure to ETS compounds by excluding the effects of other sources of pollution. In this study, we assessed the individual exposure levels to ETS compounds using a nicotine passive sampler and PM_2.5 sensor in 258 non-smokers. Median nicotine and PM_2.5 concentrations were 0.065 and 7.5 µg m^− 3, respectively. The median nicotine concentration was nearly identical to that found in non-smoking areas (0.05 µg m^− 3). The median PM_2.5 concentrations were below the standard value for indoor PM_2.5 concentrations (12 µg m^− 3). These results indicated that the effect of passive smoking was rather modest. Nicotine concentrations in individuals exposed to passive smoking indoors were significantly higher than in those not exposed to passive smoking. Nicotine exposure from domestic passive smoking was twice that from non-domestic passive smoking. There was no significant difference in PM_2.5 exposure between passive smoking in domestic and non-domestic settings. Moreover, it was suggested that passive smoking was equivalent to the act of smoking 2.4 × 10^− 3 cigarettes per day.</p></div>","PeriodicalId":49109,"journal":{"name":"Air Quality Atmosphere and Health","volume":"17 12","pages":"2767 - 2773"},"PeriodicalIF":2.9,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11869-024-01591-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141775613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using data from the China Health and Retirement Longitudinal Study (CHARLS), which included 8,700 people who were first assessed in 2011 and followed through 2018, this study aimed to investigate this association. The cognitive function examination measured three dimensions: memory, executive function, and orientation, from which a global cognitive function score was calculated. The study defined atmospheric ozone improvement as the decrease in average ozone concentration between the three-year periods preceding and succeeding 2011. Linear mixed models were used to investigate the effect of atmospheric ozone and hypertension status on cognitive function changes. Subsequent subgroup and interaction analyses were performed to evaluate potential effect changes on the aforementioned connection. Using non-hypertensive participants with improved atmospheric ozone as a reference, and after adjusting for potential variables, the multivariable-adjusted beta values for global function from those with hypertension and improved atmospheric ozone, non-hypertensive and unimproved atmospheric ozone, and hypertensive and unimproved atmospheric ozone were − 0.012 (95% CI: -0.021, -0.002), -0.014 (95% CI: -0.022, -0.006), and − 0.027 (95% CI: -0.036, -0.018), respectively (P for trend &lt; 0.001).Subgroup analysis revealed that the combined effects of hypertension and atmospheric ozone exposure status on cognition were more significant in older patients, females, non-exercisers, and people without depressive symptoms at baseline. Notably, none of the interactions between the subgroups were significant (all P-interaction &gt; 0.05).

The combination of the two chambers enables the production of stable and representative aerosols, allowing for long-term exposure studies on preclinical models (i.e., healthy, and wild type mice) under controlled conditions. This work describes the coupling methodology, the operational conditions of the FORTH and CESAM chambers and the integration of the animal exposure devices to this dual chamber set-up. The protocols applied for the continuous production (here up to 72 h) of both fresh and aged BB emissions and several other pollutants are described. The range of aerosol concentrations, compositions, and properties achieved in these experiments are summarized. The aged BB aerosol had up to twice the oxidative potential (OP) of the fresh BB emissions. The study revealed significant changes in aerosol composition during the photochemical processing of the BB emissions, with the oxygen to carbon (O:C) ratio of aged BB increasing by 33% compared to the fresh. Notable volatile organic compounds (VOC) emissions, such as formaldehyde and acetonitrile, and their levels were also highlighted.

The target study area, Salda Lake, which is a special environmental protection area with Turkey's and the world's geoheritage and unique natural values, has become one of the tourist attraction areas in recent years. However, quantitative data on airborne trace metals in the region remain poorly described. This study focuses on the spatial distribution of atmospheric heavy metals through lichen monitoring for the first time around Salda Lake. The concentration of airborne metals accumulated in <i>Xanthoria parietina</i> lichen thalli samples collected from 14 sites were evaluated by multi-element analysis with Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The spatial distribution of toxic metals in the region was presented as separate pollution maps. Analysis data showed that Ni, Fe, Al, Cu and Zn accumulation levels in lichen thalli were significantly higher than reference. Visitor entrance, camping areas and the road line in the west and south of the lake were among the sample areas where metal contamination was evident. Due to the prevalence of chromium mineral deposits in the region, the high level of Cr content is also quite remarkable. It was concluded that Al, Cr, Cu, Fe, Mn, Ni, Pb and Zn in the air are high enough to threaten human health and their levels vary depending on wind direction, human activities and traffic density.

This pioneering study is the first to quantitatively assess the morbidity risks associated with exposure to these pollutants in Karachi, a megacity in Pakistan, utilizing a robust cross-sectional design. We collected 400 air quality samples over four distinct seasons, correlating these with health data from over 12,000 hospital admissions for respiratory issues.

Specifically, sulfur dioxide (SO₂) exposure was linked to increased shortness of breath in males, while exposure to nitric acid was more likely to cause COPD in males than in females. Additionally, nitrogen oxides (HNO₃) were primarily associated with asthma in males. These associations were particularly pronounced in the 0–50 age group, suggesting a demographic at greater risk. These findings not only corroborate the global body of research on the health implications of urban air pollution but also provide critical new insights into the severe impacts within Karachi.

Five factors, including indoor temperature, indoor humidity, room ventilation, dormitory toilet, and cooking conditions, were identified as objects of the study. A typical student dormitory, consisting of a toilet, a storage room and a main room, was chosen to conduct orthogonal experiments. Results are as follows: The average NH₃ concentration in dormitories was 0.59 mg/m³. 48% of the concentration levels exceeded the limits (0.20 mg/m³) specified in the <i>Standards for indoor air quality</i> (GB/T18883-2022).
