The 14 day LC50 value to earthworms was determined to be >1000 mg/kg.
An OECD 207 study (Earthworm, Acute Toxicity Test) was conducted on a
structural analogue read-across substance (Gel All MD) to assess the
acute toxicity of the substance to earthworms. The read-across substance
(Gel All MD) is a close structural analogue of Gel All DX and comparison
of the substances have shown them to be highly similar in
phyisco-chemical properties and (eco)toxicological profile. It is
therefore considered that the results from the read-across substance are
valid for the assessment of Gel All DX.
6 replicate vessels, each containing 10 worms, were prepared at a
concentration of 1000 mg/kg using an artificial soil. The exposure
duration was 14 days.
A concurrent control (without exposure the test material) was also run.
A positive control using Chloroacetamide was also run.
There were no significant mortalities or other adverse reactions to
exposure in 60 earthworms exposed to a concentration of 1000 mg/kg for a
period of 14 days. There were no significant differences between the
worm weights of the control and 1000 mg/kg group on Days 0 and 14.
The 14 day LC50 value has been determined to be >1000 mg/kg.
The results from the positive control (Chloroacetamide) gave a 14 -day
LC50 of 15 mg/kg, which was within the normal range for this compound.
