A complex combination of hydrocarbons obtained from the distillation of crude oil or natural gasoline. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C9 through C12 and boiling in the range of approximately 140°C to 220°C (284°F to 428°F).
Substance is a hydrocarbon UVCB. Test
results for biodegradation in water are used for classification. For the
purpose of risk assessment, this endpoint is characterized using
quantitative structure property relationships for representative
hydrocarbon structures that comprise the hydrocarbon blocks. The
environmental risk of this substance is assessed using the PETRORISK
model (see Product Library in PETRORISK spreadsheet attached to IUCLID
readily to inherently biodegradable. In the supporting OECD 301 study,
naphtha solvents were readily biodegraded in 28 days but not within the
10 day window. The mean of three samples was 61% theoretical biological
oxygen demand on Day 28 (Shell, 1997). In
a valid OECD 301F supporting study Kerosine Mid-Blend was not considered
readily biodegradable in 28 days, with less than 60% degradation on day
28 (58.6%). However, according to EPA guidance for biodegradability, it
is considered inherently biodegradable since significant degradation
occurred (Mobil, 1999). On
the basis of this and from the known properties of hydrocarbons in the
range C9 to C16, in their environmental classification report CONCAWE
considered that kerosines are not readily biodegradable, but as they can
be degraded by micro-organisms, they are regarded as being inherently
biodegradable (CONCAWE, 2001).
