Concentrations of heavy metals in PM2.5 and health risk assessment around Chinese New Year in Dalian, China

Twelve samples of heavy metals were analyzed by using a 1108A-1 mid-current particle sampler in Dalian, Liaoning Province, for 31 days before and after the spring festival 2019. The results showed that the concentrations of heavy metals were decreased by more than 25% during the spring festival, whi...
