Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model （GAM） was used to evaluate the specific influences of air pollutants （PM10, SO2, and NO2） on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10μg/m3 increase in concentration of PMlo at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 lag/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.

Globally, air pollution is a significant cause of death, illness and social discomfort. The problem is particularly severe in Nigeria, the country with the highest number of premature deaths due to ambient particulate matter pollution in Sub Saharan region. It is especially worrying in Lagos, the country’s commercial capital and one of the world’s fastest growing megacities. Despite growing concerns about its deadly impacts, there is currently no reliable monetary estimate of the effects of ambient air pollution, nor a comprehensive control plan in Lagos. Using available ground-level monitored data and the most recent valuation techniques, this paper estimates that in 2018 alone, ambient fine particulate matter (PM2.5) caused about 11,200 premature deaths, and generated a health cost of US$2.1 billion in Lagos. This is equivalent to about 2.1 percent of Lagos’ GDP in the same year. These results call for an urgent plan of action to improve air quality in the city, with primary focus on the main pollution sources: road transport, industrial emissions, and power generation.

The paper analyzed the concentrations of trace metals in fine and respirable particulates (fine-PM1 and PM2.5;respirable-PM10) to determine baseline concentrations in the ambient air and the factors impacting its distribution such as land use and time of year when levels may be concerning to public health. Measurements of particulates along with meteorological parameters were made at four sites over the heavily populated west coast of Trinidad (10䓠'N, 61䓒'W) during March ’15-May ’16, representing rural, urban, mixed background and industrial land uses. The study found mean levels of trace metals to be highest at the industrial and urban stations. Public health exceedances (referenced to the Canadian AAQ public health standards (Ontario-MoE, 2012)) were measured for beryllium, cadmium, chromium, iron, manganese and nickel (in PM10). Iron, manganese and nickel, most associated with particulates at the industrial station, were in frequent exceedance. Beryllium—concentrated in coarse PM (PM2.5-10) with only a single measured exceedance at the mixed background station likely poses minimal threat to the health of the nearby population. Cadmium—concentrated in fine PM which peaked once only at the rural station was likely due to an irregular event within a narrow timeframe during the time of sampling. Iron and manganese were frequently above the Canadian public health threshold, but predominated in the coarse PM fraction, suggesting localised sources. Nickel, concentrated in the fine PM fraction, was frequently in exceedance particularly at the industrial station
