“…For SO 2 , the significant positive association (risk increase = 2.3%, 95% CI: 0.1-4.7%) per 10 µg/m 3 was limited to the single pollutant model, with no evidence of independent associations, particularly after co-pollutant adjustments with PM 10 and O 3 . Our result is similar to the one of an earlier study [7] but is at least three times higher than pooled estimates from LMIC studies [31], two times higher than single and multiple-pollutant meta-analysis estimates for North America and Europe [33], and five times higher than a respective estimate for all-cause mortality [6].…”

“…In addition, 10 µg/m 3 increases in NO 2 and O 3 were associated with an elevated risk of 0.72% (95% CI 0.59-0.85%) and 0.43% (95% CI 0.34-0.52%) in daily all-cause mortality, respectively [5]. Another meta-analysis found a positive association between SO 2 and all-cause mortality with an estimated additional risk of 0.59% (95% CI: 0.46-0.71%), for a 10 µg/m 3 increment in 24-h concentration [6].…”

Background: The health effect of air pollution is rarely quantified in Africa, and this is evident in global systematic reviews and multi-city studies which only includes South Africa. Methods: A time-series analysis was conducted on daily mortality (cardiovascular (CVD) and respiratory diseases (RD)) and air pollution from 2006–2015 for the city of Cape Town. We fitted single- and multi-pollutant models to test the independent effects of particulate matter (PM10), nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone (O3) from co-pollutants. Results: daily average concentrations per interquartile range (IQR) increase of 16.4 µg/m3 PM10, 10.7 µg/m3 NO2, 6 µg/m3 SO2 and 15.6 µg/m3 O3 lag 0–1 were positively associated with CVD, with an increased risk of 2.4% (95% CI: 0.9–3.9%), 2.2 (95% CI: 0.4–4.1%), 1.4% (95% CI: 0–2.8%) and 2.5% (95% CI: 0.2–4.8%), respectively. For RD, only NO2 showed a significant positive association with a 4.5% (95% CI: 1.4–7.6%) increase per IQR. In multi-pollutant models, associations of NO2 with RD remained unchanged when adjusted for PM10 and SO2 but was weakened for O3. In CVD, O3 estimates were insensitive to other pollutants showing an increased risk. Interestingly, CVD and RD lag structures of PM10, showed significant acute effect with evidence of mortality displacement. Conclusion: The findings suggest that air pollution is associated with mortality, and exposure to PM10 advances the death of frail population.

“…Indeed, novel evidence linking air pollution to morbidity and mortality supported the need for an update of the WHO AQGs, as presented in the session by Michal Krzyzanowski. The new AQGs [ 1 ], released on 22 September 2021, reviewed and integrated the available evidence on the health effects of particulate matter (PM) [ 13 , 14 ], ozone (O 3 ) [ 14 – 16 ], nitrogen dioxide (NO 2 ) [ 14 – 16 ], sulfur dioxide (SO 2 ) [ 16 , 17 ] and carbon monoxide [ 18 ] following the WHO handbook for guideline development [ 19 ], which warrants transparency and robustness. As introduced earlier, according to one of the resulting meta-analyses assessing the body of evidence on long-term exposure to NO 2 , an increased risk of death was associated with NO 2 concentrations as low as 10 μg·m −3 , supporting the reduction of the 2005 WHO-endorsed limit values by over 70% [ 15 ] ( table 1 ).…”

ERS International Congress 2021: highlights from the Epidemiology and Environment Assembly

et al. 2022

View full text Add to dashboard Cite

In this article, early career members of the Epidemiology and Environment Assembly of the European Respiratory Society (ERS) summarise a selection of four sessions from the Society's 2021 virtual congress. The topics covered focus on chronic respiratory disease epidemiology, the health effects of tobacco and nicotine, and the respiratory health impact of environmental exposures and climate change. While the burden of chronic respiratory diseases such as COPD is expected to increase in the next decades, research on modifiable risk factors remains key. The tobacco and nicotine research presented here focuses on recent evolutions in cigarette alternatives, including vaping and the use of heated tobacco products, and changes in behaviours related to the coronavirus disease 2019 pandemic. The 2021 World Health Organization air quality guidelines were also a major topic of the congress. Despite their benefits, challenges remain in driving and implementing environmental health policies to take into account the respiratory effects observed at very low air pollution concentrations, as well as the impact of climate change on environmental exposures.

“…Moreover, there is no major industrial area, in both HT and LT areas, which removes the industrial source for SO 2 . SO 2 has been associated with eye irritation, breathing problems, chest pains, heart disease, and respiratory mortality [48]. Inhalation of highly soluble SO 2 will be metabolized into sulfites, which can interrupt DNA synthesis and activate chromosomal abnormality [3].…”

This study aimed to investigate the association between traffic-related air pollution (TRAP) exposure and histone H3 modification among school children in high-traffic (HT) and low-traffic (LT) areas in Malaysia. Respondents’ background information and personal exposure to traffic sources were obtained from questionnaires distributed to randomly selected school children. Real-time monitoring instruments were used for 6-h measurements of PM10, PM2.5, PM1, NO2, SO2, O3, CO, and total volatile organic compounds (TVOC). Meanwhile, 24-h measurements of PM2.5-bound black carbon (BC) were performed using air sampling pumps. The salivary histone H3 level was captured using an enzyme-linked immunosorbent assay (ELISA). HT schools had significantly higher PM10, PM2.5, PM1, BC, NO2, SO2, O3, CO, and TVOC than LT schools, all at p < 0.001. Children in the HT area were more likely to get higher histone H3 levels (z= -5.13). There were positive weak correlations between histone H3 level and concentrations of NO2 (r = 0.37), CO (r = 0.36), PM1 (r = 0.35), PM2.5 (r = 0.34), SO2 (r = 0.34), PM10 (r = 0.33), O3 (r = 0.33), TVOC (r = 0.25), and BC (r = 0.19). Overall, this study proposes the possible role of histone H3 modification in interpreting the effects of TRAP exposure via non-genotoxic mechanisms.
