“…It could have been possible an URTI outbreak occurred at the time of this survey, but this was unlikely as there was no report of such an outbreak by health authorities in our surveyed area in the six-month period of our survey. The prevalence of respiratory symptoms determined in this survey is similar to that obtained in other surveys in rural areas of Kenya (Feikin et al, 2011), and in industrialized countries where air pollution is high (Kumar et al, 2007;Ranzi et al, 2014).…”

Background: Household air pollution is a leading risk factor for respiratory morbidity and mortality in developing countries where biomass fuel is mainly used for cooking. Materials and Method: A household cross-sectional survey was conducted in a predominantly rural area of Ghana in 2007 to determine the prevalence of respiratory symptoms and their associated risk factors. Household cooking practices were also assessed as part of the survey. Results: Household heads of twelve thousand, three hundred and thirty-three households were interviewed. Fifty-seven percent (7006/12333) of these households had at least one child less than five years of age. The prevalence of symptoms of acute lower respiratory infections (ALRI) was 13.7% (n= 957, 95% CI 12.8 -15.5%). A majority (77.8%, 95% CI, 77.7 -78.5%) of households used wood as their primary fuel. Majority of respondents who used wood as their primary fuel obtained them by gathering wood from their neighborhood (95.6%, 9177/9595) and used a 3-stone local stove for cooking (94.9%, 9101/9595). In a randomly selected subset of respondents, females were the persons who mostly gathered firewood from the fields (90.8%, 296/326) and did the cooking (94.8%, 384/406) for the household. Conclusion: Symptoms of ALRI reported by caregivers is high in the Kintampo area of Ghana where biomass fuel use is also high. There is the need to initiate interventions that use improved cook stoves and to test the health benefits of such interventions.

“…Thus, the estimation of indoor PM 10 , SO 2 , and NO 2 levels is with great difficulty. In the past decade, a number of studies have investigated the indoor-outdoor (I/O) ratio of PM 10 , SO 2 , and NO 2 levels (McCormack et al 2008;Pekey et al 2010;Mi et al 2006;Kumar et al 2007; Wichmann et al Klinmalee et al 2009). The differences between these outdoor values and the true exposures are an inherent and unavoidable type of measurement error.…”

People living in the urban area and the surrounding suburban area have disparities in exposure and health risks due to different levels of ambient air pollutants. The main objective of this study is to investigate the concentrations, seasonal variations, and related health risks of ambient air pollutants (PM 10 , NO 2 , and SO 2 ) in urban and suburban areas of Ningbo, China. The results showed that the average PM 10 , NO 2 , and SO 2 concentrations in the urban area were 85.2, 49.3, and 37.4 lg/m 3 , which were 1.13, 1.25, and 1.41 times the values of the suburban area during the period of March 2009 to February 2010. For the potential health risk analysis, the residents have been divided into four age categories namely, infants, children (1 year), children (8-10 years), and adults. The analysis took into account age-specific breathing rates, body weights for different age categories. The results showed that the potential health risks to respiratory disease for all age categories living in urban area were higher than those in suburban area.

DOI: https://doi.org/10.1525/elementa.259 RESEARCH ARTICLEA decade of changes in nitrogen oxides over regions of oil and natural gas activity in the United States ). In the high-production phase (2010-15), we find an increasing NO x trend in 5 of the 7 study basins (0.4 to 4.5% yr ). Over the most intensive oil-producing shale plays (Bakken, Eagle Ford, Permian and Niobrara-Codell), we observe a rapid growth (1-4.5% yr -1 ), which correlates well (r 2 = 0.6-0.9) with their annual oil production rates and/or drilling rigs. In contrast, trends across the mainly gas-producing regions (Haynesville, Barnett, and Marcellus-Utica) show decreases (-0.4 to -1.7% yr ) may be an indication of a small regional increase. Our study shows the important decadal effect that shale oil and natural gas operations has had on the tropospheric NO 2 levels, and the potential consequences for regional air quality.
