Short chain chlorinated paraffins (SCCPs),as a class of emerging organic pollutants, have been listed in the candidates of potential persistent organic pollutants (POPs) under the Stockholm Convention(SC)in 2006, and the POPs review committees considered SCCPs to fulfill the criteria of Annex A of the SC in 2017. Due to their broad industrial production and application in China, SCCPs have been found in high levels in different environmental matrixes. In this paper, the sources, releases, analytical methods, the current pollution situation in various environmental matrixes and the toxicity of SCCPs are reviewed. Meanwhile, the problems in present studies and the future research demands are also summarized in this paper.
