IJERPH, Vol. 17, Pages 1287: Levels and Determinants of Fine Particulate Matter and Carbon Monoxide in Kitchens Using Biomass and Non-Biomass Fuel for Cooking International Journal of Environmental Research and Public Health doi: 10.3390/ijerph17041287 Authors: Zafar Fatmi Georgia Ntani David Coggon To assist interpretation of a study in rural Pakistan on the use of biomass for cooking and the risk of coronary heart disease, we continuously monitored airborne concentrations of fine particulate matter (PM2.5) and carbon monoxide (CO) for up to 48 h in the kitchens of households randomly selected from the parent study. Satisfactory data on PM2.5 and CO respectively were obtained for 16 and 17 households using biomass, and 19 and 17 using natural gas. Linear regression analysis indicated that in comparison with kitchens using natural gas, daily average PM2.5 concentrations were substantially higher in kitchens that used biomass in either a chimney stove (mean difference 611, 95% CI: 359, 863 µg/m3) or traditional three-stone stove (mean difference 389, 95% CI: 231, 548 µg/m3). Daily average concentrations of CO were significantly increased when biomass was used in a traditional stove (mean difference from natural gas 3.7, 95% CI: 0.8, 6.7 ppm), but not when it was used in a chimney stove (mean difference −0.8, 95% CI: −4.8, 3.2 ppm). Any impact of smoking by household members was smaller than that of using biomass, and not clea...

CONCLUSIONS: More neonatal surgeries (491 vs. 74 patients) were performed than those in the past (1984-1999). The surgical outcomes were much better than before. Our surgical outcomes revealed that the Republic of Korea has been transformed from a country receiving help to a country that helps other low socioeconomic status countries.

Conclusions: The present study provided robust epidemiologic evidence of associations between day-to-day NO2 and mortality from total natural causes and main cardiorespiratory diseases that might be independent of other criteria air pollutants.

CONCLUSIONS: This nationwide study demonstrated associations of daily SO2 concentrations with increased total and cardiorespiratory mortality, but the associations might not be independent from NO2. PMID: 29715611 [PubMed - as supplied by publisher]

What is the issue? "Air pollution is contributing to about 40,000 early deaths a year in the UK," BBC News reports. The figures are the conclusion of a report assessing the impact of air pollution on public health in the UK. The report, published by the Royal College of Physicians and the Royal College of Paediatrics and Child Health, discusses the lifelong impact of air pollution. It presents a number of recommendations to the public, businesses and governments to make changes and reduce air pollution. The expert panel states: "Real change will only occur when everyone accepts this responsibility, and ...
