Perchlorate in tea, as an emerging contaminant, poses a potential risk for food safety, human health and foreign trade, which has raised increasing concerns over the contamination of tea with perchlorate. In this paper, pollution sources, status and the main causes of pollution in tea of perchlorate were described. The analytical techniques of perchloratein tea samples were also summarized. These data would provide references for studies of environmental transport behaviors, agri-food safety, human health risk and relevant standards of security in China.
