No relevant data on SCCPs is currently availble. Exposure of wheat, oilseed rape and mungbean seedlings during emergence and growth up to 28 days to Cereclor 52 (52% chlorinated) at nominal concentrations up to 5000 mg/kg dry weight of soil had no significant adverse effects. Therefore, the NOEC for these three species is >= 5000 mg/kg dry weight (a measured concentration of about 5800 mg/kg dry weight soil).
No relevant data on SCCPs is currently
In GLP studies conducted according to OECD
Guideline 208, the toxicity of Cereclor S52 (a C14-17 chlorinated
paraffin; 52% chlorination) at up to nominal concentrations of 5000
mg/kg dry wt soil to seedlings of wheat (Triticum aestivum), oilseed
rape (Brassica napus) and mungbean (Phaseolus aureus) was studied during
emergence and growth up to 28 days. A small amount of 14C-labelled
n-pentadecane (51% chlorinated) was mixed with test substance at the
lowest, middle and highest concentrations tested to facilitate analysis
in soil and plant tissue (Thompson et al. 2001d). No significant effects
were seen on seedling emergence at 14 days and growth up to 28 days with
any of the three species in this study, and all seedlings appeared
normal, demonstrating that the chlorinated paraffin was not toxic to
these species under the conditions of the study. The NOEC for these
three species is >= 5000 mg/kg dry wt soil (the highest tested nominal
concentration; a measured concentration of 5800 mg/kg dry wt soil).
conducted according to the updated OECD Guideline 208 are designed to
assess the potential effects of substances on seedling emergence and
growth. Therefore, it is specific to a part of the plant's life-cycle
and does not cover chronic effects or effects on reproduction. However,
it is assumed to cover a sensitive stage in the life-cycle of a plant
and therefore data obtained from this study can be used to estimate
In view of
the similarities in structure and physiochemical properties [between
SCCPs and MCCPs], it can reasonably be predicted that SCCPs would also be
of low toxicity to these seedlings.
