Results and discussion

Applicant's summary and conclusion

Executive summary:

Based on intrinsic properties of Benzotriazole, Tolyltriazole and their conjugated sodium salts binding to organic soil compounds is assumed. However, polar interactions based on the ionic form of salts and the strong dipole moments in the uncharged molecules are supposed to be more relevant for the retention in soil.

Hence, long-term exposure to soil-dwelling organisms that feed on soil particles are considered as most relevant and consequently a test on reproduction with earthworms has been proposed.
