Control Evaluation

Local air pollutants (LAPs), such as carbon monoxide, hydrocarbon, sulfur oxide, nitrogen oxide, ozone, and particulate matter, as well as greenhouse gas (GHG) emissions from the transport sector are rapidly increasing in the People’s Republic of China. Various measures to control LAPs have been implemented in the country, along with the adoption of strategies to mitigate GHG emissions. The connection between LAP and GHG emission control and reduction offers an opportunity to address both problems simultaneously. This paper presents a methodology that measures the benefits of co-control evaluation on mitigating LAP and GHG emissions. It highlights the methodology’s potential to help maximize measures and strategies that have significant co-control effects.

Abstract. Measurements of gaseous elemental Hg (GEM), other air pollutants including SO2, NOx, O3, PM2.5, CO, and meteorological conditions were carried out at Chongming Island in East China from March 1 in 2014 to December 31 in 2016. During the sampling period, GEM concentrations significantly decreased from 2.68 ± 1.07 ng m−3 in 2014 to 1.60 ± 0.56 ng m−3 in 2016. Monthly mean GEM concentrations showed a significant decrease with a rate of −0.60 ng m−3 yr−1 (R2 = 0.6389, p

Abstract Background: Previous research has suggested an association between maternal exposure to ambient air pollutants and the risk of congenital heart defects (CHDs). However, the effect of individual prenatal exposure to indoor air pollutants on CHD occurrence has not been reported.Methods: We carried out a hospital-based case-control study to investigate the association between personal air pollution exposure during pregnancy and the risk of CHDs in offspring. A total of 32 cases and 74 controls were included in this study from two hospitals in East China. We investigated maternal and residential environmental characteristics using a questionnaire and obtained personal indoor air samples to assess particulate matter (PM) and volatile organic compounds (VOCs) from 22–30 gestational weeks; formaldehyde, benzene, toluene, xylene, total VOCs (TVOCs), PM10, and PM2.5 were assessed. Logistic regression was performed to assess associations and interactions among individual indoor air pollutants and CHDs after adjusting for confounders. The potential residential environmental factors affecting the risks of indoor air pollutants on CHDs were also assessed.Results: Median TVOC (0.430 vs. 0.005 mg/m3, P < 0.001), PM2.5 (12.00 vs. 8.00 µg/m3, P=0.037) and PM10 (13.50 vs. 8.00 µg/m3, P=0.028) exposure levels in cases were significantly higher than those in controls. In a regression model adjusted for confounders, exposure to high levels of indoor TVOCs, PM2.5 and PM10 during pregnancy was associated with risks for CHDs and the occurrence of some major CHD subtypes in offspring. These risk effects were enhanced among pregnant woman living in a newly renovated house or near heavy-traffic roads but were mitigated by household usage of smoke ventilators when cooking. We observed a positive interaction of maternal exposure to TVOCs and PM2.5 in regard to the risk for CHDs.Conclusions: Maternal exposure to indoor VOCs and PMs may increase the risk of giving birth to foetuses with CHDs.
