ERA - CalTOX

CalTOX is a risk assessment model that calculates the emissions of a chemical, the concentration of a chemical in soil, and the risk of an adverse health effect due to a chemical. It consists of two parts:

CalTOX is a spreadsheet model. Different model versions of CalTOX have been used for different purposes and in various publications.

CalTOX Version 4.0 (Beta)
This is the beta test version of the CalTOX 4.0 model and has not been fully tested. There are many different brands of PCs and multiple versions of Windows and Excel currently in use, and it was not possible to test CalTOX on the full spectrum of machine/software/printer combinations with which it could be used. Problems may occur in the execution of macros and in the display and printing of the spreadsheet information. There could be errors in the mathematical algorithms that we have not yet identified. This program should be considered a research tool and not be assumed to be endorsed for use in regulatory decision making.

Because the CalTOX model was funded and originally distributed free of charge by the State of California, it is in the public domain and is still distributed at no cost or fee. Because this software is distributed without fee the THERE IS NO TECHNICAL SUPPORT FOR CalTOX.

Human Toxicity Potential The Human Toxicity Potential is a characterization factor used to compare different toxic releases in Life-Cycle Assessment and the evaluation of the Toxics Release Inventory. CalTOX Version 2.3 was used to calculate the potential dose.
