Chlorinated Paraffins in Car Tires Recycled to Rubber Granulates and Playground Tiles.

ABSTRACT: Chlorinated paraffins (CPs) are used in various products to improve their physicochemical characteristics. Due to recycling, CPs may end up in "new" recycled products. In this study we investigated CPs present in end-of-life car tires that are recycled to rubber granulates used on artificial soccer fields, and playground tiles. The ∑CP(C₁₀-C₃₀) concentrations ranged from 1.5 to 67 μg/g in car tires, 13-67 μg/g in rubber granulates, and 16-74 μg/g in playground tiles. MCCPs were the dominant CP group with an average contribution of 72%. LCCPs up to C₃₀, were detected for the first time in car tires, rubber granulates, and playground tiles. The CPs application in tires is unclear, the low CP concentrations found in this study (<0.007%) could possibly indicate
