Under valid conditions, the phytotoxicity of the test substance (meta-Diisopropanolbenzene) on seed of commercially important terrestrial plants was conducted according to the following guidelines: “The guidelines for the testing of chemicals” (HJ/T 153-2004); Ecological Effects Test Guidelines, OPPTS 850.4200, Seed Germination/Root Elongation Toxicity Test. EPA 712-C-96-154, April 1996 etc.
In the test, ten plant species of Lycopersicon esculentum (tomato), Cucumis sativus (cucumber), Lactuca sativa (lettuce), etc. were exposed to a series of concentrations of the test substance. A blank control without the test substance was run at the same time. During the whole test period, the pH values of the freshly prepared control and Test Media were between 6.8 and 7.4, and the temperature in the germination facility was maintained in the range of 24oC to 25oC. At the end of the test, more than 65 percent of the control seeds germinated and the roots developed were longer than. So the study met the acceptability criteria prescribed by the protocol. Therefore the test was considered valid.
The results showed that under valid test conditions, the LOEC and the NOEC are greater than 1000 mg/L (nominal concentration). The EC50 for either germination or root elongation is greater than 1000 mg/L (nominal concentration).
