Application of a model to estimate total concentrations of dioxins and DL-PCBs in pork production in Chile

This research presents a model to estimate the total concentration or C Total of dioxins (PCDD), furans (PCDF) and dioxin-like polychlorinated biphenyls (DL-PCBs) in pork. The model was applied considering the categories of raw materials that make up two reference diets for pig production in Chile....
