Additional information

In a guideline (PARCOM) and GLP study, the 10 -day LC50 of a substance that matches the description "Poly(oxy-1,2,-ethanediyl), α-butyl, ω-hydroxyl", in the sediment amphipod Corophium volutator was determined to be 6597 mg/kg dry sediment (95% CL 4767 - 8420 mg/kg). There is no data available on the chronic toxicity of sediment dwelling species.
