This Technical Manual describes the algorithms, methodologies, data sources, and input and output options and capabilities of the SHEDS-Dietary model v1. ORD, in conjunction with OPP, developed this Agency state-of-the-science model to probabilistically estimate dietary exposures to inform regulatory risk assessments as well as address science questions for research purposes. ORD’s SHEDS-Dietary modeling research focused on enhancing the science of probabilistic dietary exposure assessments. OPP collaboration on SHEDS-Dietary model development has considered criteria for regulatory use: peer reviewed / transparent (algorithms); publicly available (free or nominal cost); and consistent with EPA/OPP policies and guidelines.
