Endpoint:
toxicity to bees: acute oral
Data waiving:
exposure considerations
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING:
According to the TNsG on Data Requirements for Active Substances and Biocidal Products, and REACH Guidance, an acute oral toxicity test in honeybees is required for insecticides, acaricides and substances in products to control other arthropods which are used outside. There will be no direct exposure of honeybees to chlorine dioxide. Therefore, an acute oral toxicity test in honeybees is not required.

Description of key information

Chlorine dioxide reacts rapidly in aqueous solution degrading to chlorite and chlorate as dominant species under environmental conditions. In the absence of oxidisable substances, and in the presence of pH > 9, chlorine dioxide dissolves in water and decomposes with the slow formation of chlorite and chlorate ions.

Key value for chemical safety assessment

Additional information

According to the TNsG on Data Requirements for Active Substances and Biocidal Products, and REACH Guidance, an acute oral toxicity test in honeybees is required for insecticides, acaricides and substances in products to control other arthropods which are used outside.

There will be no direct exposure of honeybees to chlorine dioxide. Therefore, an acute oral toxicity test in honeybees is not required. Chlorine dioxide react easily and rapidly generating chlorite and chlorate as dominant species. In the absence of oxidisable substances, and in the presence of pH > 9, chlorine dioxide dissolves in water and decomposes with the slow formation of chlorite and chlorate ions. No key studies valid were found in chlorite and chlorate for evaluated the toxicity to terrestrial arthropods.
