In Tongliang, China, a coal-fired power plant was the major pollution source until its shutdown in 2004. We enrolled two cohorts of nonsmoking women and their newborns before and after the shutdown to examine the relationship between prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) and fetal and child growth and development. PAHs were used to measure exposure to air pollution generated...
Stable carbon isotope ratios were determined for the OC and EC fractions of PM 2.5 collected from 14 Chinese cities in January and June/July of 2003. The period-averaged isotope values (δ 13 C) varied from −26.90‰ to −23.08‰ for OC and −26.63‰ to −23.27‰ for EC. A strong correlation (R 2 =0.70, p<0.0001) between δ 13 C OC and δ 13 C EC was...
