The PubMed search identified well over 300 papers for drugs and chemicals. The list was reduced to approximately 60-70 in the general field of toxicology, and again reduced to 30+ papers with authors who have an SOT affiliation. Subsequently, a short list of 9 papers was selected, including the RSI paper on application of PBPK models in estimating human brain tissue manganese concentrations.
A copy of the paper is available here: Ramoju-2017-The application of PBPK models in estimating human brain tissue manganese concentrations.
