Adverse Health Effects

Ambient air pollution is a leading environmental risk factor and its broad spectrum of adverse health effects includes a decrease in lung function. Socioeconomic status (SES) is known to be associated with both air pollution exposure and respiratory function. This study assesses the role of SES either as confounder or effect modifier of the association between ambient air pollution and lung function. Cross-sectional data from three European multicenter adult cohorts were pooled to assess factors associated with lung function, including annual means of home outdoor NO2. Pre-bronchodilator lung function was measured according to the ATS-criteria. Multiple mixed linear models with random intercepts for study areas were used. Three different factors (education, occupation and neighborhood unemployment rate) were considered to represent SES. NO2 exposure was negatively associated with lung function. Occupation and neighborhood unemployment rates were not associated with lung function. However, the inclusion of the SES-variable education improved the models and the air pollution-lung function associations got slightly stronger. NO2 associations with lung function were not substantially modified by SES-variables. In this multicenter European study we could show that SES plays a role as a confounder in the association of ambient NO2 exposure with lung function.

Abstract Background There is an increasing range of adverse health effects associated with air pollution at very low concentrations. Few studies have assessed respiratory parameters among filling station attendants. Objectives This study assessed air pollutants; particulate matter (PM10) and total volatile organic compounds (TVOC) concentrations at filling stations as well as determined forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR) levels among filling station attendants. Methods A cross-sectional study was conducted to assess PM10 and TVOC concentrations at 20 systematically selected filling stations in Ibadan North Local Government Area, Ibadan for 2 months using a Thermo Scientific pDR 1500 PM10 monitor and SF2000-TVOC meter. FEV1 and PEFR levels were measured in order to assess the effect of exposure to PM10 and TVOC on lung function of 100 filling station attendants using a PIKO-1 Electronic peakflow/FEV1 meter. Results Total mean PM10 concentrations (μg/m3) in the morning (43.7±16.5) and afternoon (27.8±7.9) were significantly lower (p<0.01) than the World Health Organization (WHO) guideline limit (50 μg/m3). Total mean TVOC concentrations (ppm) in the morning (12.0±3.4) and afternoon (5.6±2.4) were however significantly higher (p<0.01) than the Occupational Safety and Health Administration (OSHA) guideline limit (3 ppm). Mean FEV1 for filling station attendants was 1.63±0.39 and PEFR was 171.7±45.9. Conclusion Filling stations are hotspots for the emission of VOCs and PM10. However, filling station attendants in this study are at risk of exposure to high concentrations of VOCs but not PM10. FEV1 and PEFR values among filling station attendants were very low which could possibly be attributed to extended exposure to air pollutants. Regular medical examinations should also be conducted on filling station attendants in order to aid early detection of deviations in their health status.

Ambient air pollution increases the risk of respiratory mortality, but evidence for impacts on lung function and chronic obstructive pulmonary disease (COPD) is less well established. The aim was to evaluate whether ambient air pollution is associated with lung function and COPD, and explore potential vulnerability factors.We used UK Biobank data on 303 887 individuals aged 40–69 years, with complete covariate data and valid lung function measures. Cross-sectional analyses examined associations of land use regression-based estimates of particulate matter (particles with a 50% cut-off aerodynamic diameter of 2.5 and 10 µm: PM2.5 and PM10, respectively; and coarse particles with diameter between 2.5 μm and 10 μm: PMcoarse) and nitrogen dioxide (NO2) concentrations with forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio and COPD (FEV1/FVC <lower limit of normal). Effect modification was investigated for sex, age, obesity, smoking status, household income, asthma status and occupations previously linked to COPD.Higher exposures to each pollutant were significantly associated with lower lung function. A 5 µg·m−3 increase in PM2.5 concentration was associated with lower FEV1 (−83.13 mL, 95% CI −92.50– −73.75 mL) and FVC (−62.62 mL, 95% CI −73.91– −51.32 mL). COPD prevalence was associated with higher concentrations of PM2.5 (OR 1.52, 95% CI 1.42–1.62, per 5 µg·m−3), PM10 (OR 1.08, 95% CI 1.00–1.16, per 5 µg·m−3) and NO2 (OR 1.12, 95% CI 1.10–1.14, per 10 µg·m−3), but not with PMcoarse. Stronger lung function associations were seen for males, individuals from lower income households, and “at-risk” occupations, and higher COPD associations were seen for obese, lower income, and non-asthmatic participants.Ambient air pollution was associated with lower lung function and increased COPD prevalence in this large study.

BackgroundLong-term exposure to ambient air pollution leads to respiratory morbidity and mortality; however, the evidence of the effect on lung function and chronic obstructive pulmonary disease (COPD) in older adult populations is inconsistent.ObjectiveTo address this knowledge gap, we investigated the associations between particulate matter (PM), nitrogen dioxide (NO2) exposure and lung function, as well as COPD prevalence, in older Chinese adults.MethodsWe used data from the WHO Study on global AGEing and adult health (SAGE) China Wave 1, which includes 11, 693 participants from 64 townships in China. A cross-sectional analysis explored the association between satellite-based air pollution exposure estimates (PM with an aerodynamic diameter of ≤10 µm [PM10], ≤2.5 µm [PM2.5] and NO2) and forced expiratory volume in one second (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio and COPD (defined as post-bronchodilator FEV1/FVC <70%). Data on lung function changes were further stratified by COPD status.ResultsHigher exposure to each pollutant was associated with lower lung function. An IQR (26.1 µg/m3) increase in PM2.5 was associated with lower FEV1 (−71.88 mL, 95% CI –92.13 to –51.64) and FEV1/FVC (−2.81, 95% CI −3.37 to –2.25). For NO2, an IQR increment of 26.8 µg/m3 was associated with decreases in FEV1 (−60.12 mL, 95% CI –84.00 to –36.23) and FVC (−32.33 mL, 95% CI –56.35 to –8.32). A 31.2 µg/m3 IQR increase in PM10 was linked to reduced FEV1 (−8.86 mL, 95% CI −5.40 to 23.11) and FEV1/FVC (−1.85, 95% CI −2.24 to –1.46). These associations were stronger for participants with COPD. Also, COPD prevalence was linked to higher levels of PM2.5 (POR 1.35, 95% CI 1.26 to 1.43), PM10 (POR 1.24, 95% CI 1.18 to 1.29) and NO2 (POR 1.04, 95% CI 0.98 to 1.11).ConclusionAmbient air pollution was associated with lower lung function, especially in individuals with COPD, and increased COPD prevalence in older Chinese adults.

Background: There is increasing concern of ambient air pollution as a global threat to humans. The most prominent effect of air pollution is on lung function. The air pollution causes decline in lung function amongst high exposure populations. There are some most vulnerable groups who are chronically exposed to ambient air pollution like traffic policemen, roadside hawkers, Banjara community in India, E-Rickshaw drivers etc. Methods: A cross sectional study was conducted in East Delhi, India. Spirometry was done for roadside hawkers having high exposure to ambient Air pollution and   working daily for 6-8 hours for the last more than 3 years. The low exposure group was taken from personnel working inside offices. The spirometry parameters of both the groups were compared. Student ‘T’ test was applied for statistical analysis with the help of SPSS software. Results: Comparison of FVC, FEV1 and FEV1/FVC ratio among two groups revealed lower values for the high exposure group which was statistically significant. Among high exposure group the mixed pattern of ventilation defect was observed. Among low exposure group normal pattern of lung function was observed. Conclusion: Roadside hawkers are a vulnerable group to ambient air pollution resulting in their lower values of lung function parameters with resultant mixed ventilator defect and consequently high risk for development of respiratory diseases in the future.

Particulate Matter Exposure

Air pollution has a great impact on health, representing one of the leading causes of death worldwide. Previous experimental and epidemiological studies suggested the role of pollutants as risk factors for cardiovascular diseases. For this reason, international guidelines included specific statements regarding the contribution of particulate matter exposure to increase the risk of these events. In this review, we summarise the main evidence concerning the mechanisms involved in the processes linking air pollutants to the development of cardiovascular diseases.
