Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

A complete long-term dataset for the toxicity of 1H-Benzotriazole to soil organisms is available. In the study with soil macroorganisms E. andrei was exposed for four weeks to concentrations between 2.5 and 160 mg/kg soil dw. In the test no effects on mortality of individuals were observed. For reproduction an EC10 of 19.1 mg/kg soil dw was calculated. The toxicity to terrestrial plants was investigated in an OECD 208 guideline study with six different species. As most sensitive species turnip (Brassica rapa) EC50 28.5 mg/kg soil dw and tomato (Solanum lycopersicum) EC10 1.69 mg/kg soil dw for the endpoint growth (shoot fresh mass) were identified. In the study with soil microorganisms a short-term EC50 of 15.4 mg/kg soil dw and a long-term EC10 of 8.1 mg/kg soil dw were found.
All findings are in a similar range showing a comparable behaviour of 1H-Benzotriazole to the different trophic levels in soil like in the water compartment. For the CSA of the soil compartment the identified value for the growth inhibition of tomatos was selected as point of departure for the calculation of the PNECsoil.
