Sci Total Environ. 1991 Jan 01;101(1):101-9. doi: 10.1016/0048-9697(91)90108-q.

This paper describes the use of an interactive simulation system (SONCHES) as a model and databank system. The basic model is a physiologically based toxicokinetic model (partition coefficient concept). This model takes circulation times into consideration and includes a...
