Identification and evaluation of chlorinated nonane paraffins in the environment: A persistent organic pollutant candidate for the Stockholm Convention?
Short-chain chlorinated paraffins (SCCPs), with 10-13 carbon atoms, are persistent organic pollutants under the Stockholm Convention because they are persistent, toxic, and bioaccumulative. However, little information is available on CPs with < 10 carbon atoms. C-9-CPs were identified and quantif...
