where IUR (μg/m3)−1is inhalation unit risk, and EC (μg/m3) is the exposure concentration. When CR is lower than 10–6, risk can be ignored. The acceptable risk range is 10–6to 10–4, and when it is higher than 10–4, the potential cancer risks exist seriously. Results and...
Sixteen parent PAHs and twelve nitro-PAHs were measured in PM2.5 samples collected over one year (2013–2014) at nine urban sites in China. During the sampling period, concentrations of individual nitro-PAHs were one or two orders of magnitude lower than their parent PAHs. Typical seasonal vari...

They compared the performance with ground PM observations from a chemistry-transport model (CTM) simulations. The results indicated that the index of agreements (IOA) was increased from 0.36 to 0.78 and, with the 3-D CTM simulations, from 0.62 to 0.79 with the LSTM-based model. Ayturan et ...

Their seasonal ratios (OC/EC) depended on the sampling periods, varying in a wide range of 3.5–17.9 at the sites, meaning that the concentration of OC was occasionally ~18 times higher than EC at K-puszta in summer. For example, at the Košetice rural site in the Czech Republic, ...
