A method of predicting the contact migration behaviour of chemical substances, e.g. approximating dermal or oral transfer of pesticides.

摘要

The invention provides a method for estimating the dermal transfer efficiency of a chemical substance comprising a step of determining a calculated value for the dermal transfer efficiency for the time elapsed after use of the chemical substance, based on a formula wherein the temporal change in the dermal transfer efficiency is expressed as a function dependent on the -0.5 power of the time, or on a computer program incorporating the formula, and a step of establishing the calculated value determined in the previous step as the estimated dermal transfer efficiency.
