Description of key information
glutaraldehyde revealed very low acute toxicity to earthworm indicated by a LC50 value of 170 mg a.i./kg dry weight soil. The result converted to wet weight by dividing with a factor of 1.13 (EUSES manual) results in a LC50 of 150 mg a.i./kg ww.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 170 mg/kg soil dw
Additional information
The acute toxicity of glutaraldehyde 50% to earthworms was studied with Eisenia
foetida according to OECD Guideline 207 (BASF AG
01/0411/67/1). Adult earthworms (with visible clitella) were
exposed for 14 days to glutaraldehyde-treated artificial soil. The
nominal test concentrations were 0, 62.5, 125, 250, 500 and 1000 mg/kg
dry weight soil. The animals were checked after 7 and 14 days for
mortality, behaviour and body weight. Test substance-related
mortality was observed at the two highest tested concentrations of 500
(15%) and 1000 mg/kg soil (25%); at 250 mg/kg soil, no mortality was
observed. The LC50 was 170 mg a.i./kg soil.
In conclusion, glutaraldehyde revealed very low acute toxicity to
earthworm. Nevertheless, for a substance being considered as „readily
biodegradable“, it can be assumed that it will be biodegraded within the
STP process and as a consequence a transfer to the soil compartment is
not expected. In addition, the substance is not bioaccumulative.
Therefore, toxicity to soil macroorganisms is unlikely.
