Anthropogenic soil exposure can be considered negligible. There will
only be some soil contamination due to atmospheric deposition of CS2
on the soil in the immediate vicinity of industry. CS2
has no affinity for soil and its evaporation half life in soil is short.
In addition CS2 has a log Kow
value of 2.7 and is readily degradable (either biotically or
abiotically). Measured concentrations of CS2
in soil are therefore scarce and show low concentrations. The highest
reported value was <1 µg/kg soil. If this value is compared with the
PNEC for aquatic organisms (20 µg/L, see section 5.1) the PEC/PNEC ratio
< 0.05. Therefore further testing with soil organims is not a
requirement (See the guidance documents).
The 5-day EC50 for effects of CS2 on
soil micro-organisms (measured in different soils in close flasks to
prevent evaporation) was found to be 0.21 mg/kg and the 14 -d EC50 was
2.1 mg/kg. Plants exposed to CS2 in air
showed a NOEC for wheat of 633 mg/m3,
and 6.2 mg/m3 for Bush beans. These
effect levels are much higher than the highest measured environmental
concentrations in air (highest values ± 10 µg/m3,
see section 5), so we do not expect effects on plants due to the
exposure to environmental concentrations.
