Transport of chlorinated paraffins (CPs) from baking oven doors into the food.

Chlorinated paraffins (CPs) have been repeatedly detected in the kitchen environment. Especially baking ovens were contaminated with high CP amounts on the insides of the doors. To investigate if CPs could be transferred into baked food, we spiked self-synthesized single chain C-CP and C-CP standards onto the inside door of an unused, CP-free baking oven.
