TL;DR: The complex and nonlinear response of chemical compositions and sources of PM2.5 to air pollution control measures are highlighted, suggesting the importance of regional-joint control.

TL;DR: Wang et al. as discussed by the authors analyzed the temporal variation in VOC emission characteristics at a typical oil and gas field, which exhibited different VOC levels, compositions and origins compared with those in urban and industrial areas.

TL;DR: Results of PSCF and CWT indicated that the long-distance transport form north of Wuhan as far as northern and eastern of China was higher than that from the southern China while the contribution of local areas wasHigher than those from theLong-range transport.

TL;DR: Compound-specific health risk results showed that acrolein and 1,3-butadiene had the highest non-carcinogenic risk and carcinogenic risk respectively, which are conductive to the formulation of countermeasures to reduce human exposure to ambient VOCs at petrochemical industrial parks in China.

TL;DR: The observation data and model simulations found that 50% of the pollution episodes were associated with the long-range transport of air pollutants from upstream CEC source regions, which then converged in the downstream Hubei receptor region, however, local pollution was dominant for the remaining episodes because of stagnant meteorological conditions.
