A complex combination of hydrocarbons obtained by subjecting a petroleum naphtha to a sweetening process to convert mercaptans or to remove acidic impurities. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C5, predominantly C5, and boiling in the range of approximately minus 10°C to 35°C (14°F to 95°F).
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterized for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model.
In general, the narcosis-based PNEC appears to be protective when compared to measured soil toxicity data. In the case of higher molecular weight alkanes, the narcosis prediction may in fact be too conservative since no chronic acute effects are observed at concentrations that are almost three orders of magnitude higher. Based on this preliminary analysis, PNEC values for assessing the environmental risk to the soil compartment using the hydrocarbon block method are appropriate.
