In order to check the EG-sorption/desorption test for new chemicals which is in preparation, an international ringtest was carried out. This report deals with our results. The sorption/desorption test was carried out for the chemicals atrazine and lindane, in three different soil types. The proposed test seems to be valuable in order to get some information about sorption/desorption behaviour of new chemicals in soil. Several improvements for the proposed test are suggested.
