The study was conducted to determine the acute toxicity of test substances (meta-Diisopropanolbenzene) to earthworm according to the guidelines of SEPAHJ/T 153 -2004, “the guidelines for the testing of chemicals”; and with the reference toProcedure 207 of the ‘Guidelines for Testing of Chemicals’ of the OECD: "Earthworm, Acute Toxicity Tests” (1984) etc.
During this test, the artificial soils was used with the moisture content of the test medium controlled in range of 32% to 36% with pH from 6.0 to 6.2. The test conditions were maintained as follows: temperature of 20oC to 22oC, humidity of 80% to 85% and continuous light with intensity of 400 lux to 800 lux.
Based on the result of range-finding test and the Limit Test, the14d LC50 of the test substance in the artificial soil was determined to be greater than 1000 mg/kg dry weight soil. The No-Observed-Effect Concentration (14d-NOEC) was greater than 1000 mg/kg dry weight soil. According to the toxicity catalogue of new chemicals, the test substance (meta-Diisopropanolbenzene) is low toxic to earthworms (Eisenia foetida).
