CAS number: 64742-88-7
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).
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).
Biodegradation in water, screening test:
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 Section 13).
Biodegradation in water and sediment,
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 using quantitative structure
property relationships for representative hydrocarbon structures that
comprise the hydrocarbon blocks used to assess the environmental risk of
this substance with the PETRORISK model (see Product Library tab in
PETRORISK spreadsheet attached in IUCLID section 13).
Biodegradation in soil:
