Detecting and Quantifying Chlorinated Paraffins in The Great Lakes’ Top Predator Fish
The Great Lakes system is the largest source of surface freshwater worldwide. However, the Great Lakes have been exposed to numerous sources of contamination over the past century due to agricultural, industrial, and waste disposal activities. A major class of pollutants that have affected the Great Lakes are halogenated organic compounds, which exhibit persistent, bioaccumulative, and toxic (PBT) properties. An example of this class are chlorinated paraffins (CPs), which are technical mixtures of polychlorinated n-alkanes with different chain lengths and chlorination degrees. CPs are among the most widely produced industrial chemicals today. This is because they have various applications in the industry as plasticizers, lubricants, flame retardants, and metal working fluids. In recent years, CPs have garnered increased attention due to their PBT properties and long-range transport, which have led to their detection in various environmental matrices. However, industrial CPs are synthesized through a nonselective radical reaction, resulting in the formation of thousands of structural and stereoisomers. The separation and identification of these isomers using conventional chromatography techniques is extremely challenging due to the coelution of the isomers. In this study, we develop a method for the separation and quantification of CPs in the Great Lakes’ top predator fish using 2-dimension gas chromatography (GCxGC) which has enhanced separation power and peak capacity
