Only one acute toxicity study is available on terrestrial organisms.

Earthworm

A study was performed to assess the acute toxicity of the test material to the earthworm (Eisenia foetida) in an artificial soil. The method followed that described on the OECD Guidelines for testing of Chemicals (1984) No 207, and EEC Comminssion Directive 87/302/EEC.

Following a preliminary range-finding study, 60 earthworms were exposed (6 replicates of 10 worms) to a single concentration of 1000 mg/kg of soil for a period of 14 days. The number of mortalities were determined after 7 and 14 days exposure. A positive control study using chloroacetamide, conducted approximately every 6 months, is reported for reference purposes.

The LC50(14 d) for the test material to earthworms (Eisenia foetida) based on nominal test concentrations was greater than 1000 mg/kg. The NOEC was given as 1000 mg/kg.
