Face masks contribute greatly to the protection of human health in the epidemic of corona virus disease 2019(COVID-19).However,the extensive use of masks has brought new challenges to the environment and human health,such as vast plastic and plastic particle waste[1,2].As some chemicals can be involved in raw materials of the masks,such as semi-volatile organic com-pounds(SVOCs),the face masks could be a potential source of chemical exposure to humans,posing risks to human health.How-ever,there are still no mandatory standards or regulation docu-ments that impose restriction on the SVOCs in the face masks.In addition,there is still a knowledge gap on the occurrence and risks of the chemical exposure from the face masks.
