Soil dwelling arthropods are not likely to be exposed to Renewable hydrocarbons, C15-C18, branched alkanes as these compounds are readily biodegradable. Moreover, high concentrations of Renewable hydrocarbons, C15-C18, branched alkanes are necessary to obtain toxic effects in terrestrial arthropods.
Taverner et al. (1999) investigated the effects of two paraffin mixtures, C15 Ampol CPD (100% C15 alkanes) and C23 Ampol DC Tron NR (70% paraffins, 28% naphthenics, 2% aromatics), on the lepidopteran pestEpiphyas postvittana. Hydrocarbons were directly applied on the organisms and 24h-LC50 varied from 0.47 ml/L (i.e. approximately 375 mg/L) for the larval stage Instar III to more than 50 ml/L (i.e. 37.5 g/L) for the adults. The 14-day NOEC for instar III was found to be 0.1 ml/L (i.e. approximately 80 mg/L). These presented results support the fact that no further studies are deemed necessary to conduct.
Furthermore, according to Chapter R.7c (Endpoint specific guidance) of ECHA Guidance on information requirements and chemical safety assessment, in the case of readily biodegradable substances which are not directly applied to soil it is generally assumed that the substance will not enter the terrestrial environment and as such there is no need for testing of soil dwelling arthropods. According to the data provided in the dossier, Renewable hydrocarbons, C15-C18, branched alkanes are readily biodegradable. Therefore, no further testing on soil dwelling arthropods is required.
