Description of key information
Two 96 hr tests on Mysidopsis bahia yielded LC50s for benzyl butyl phthalate of >0.74 mg/L and 0.9 ppm.
Key value for chemical safety assessment
Additional information
Two 96 hr acute toxicity studies of benzyl butyl phthalate on the saltwater shrimp Mysidopsis bahia are available. Both are acceptable for use as key studies for this endpoint.
EG&G Bionomics (1979) report a 96 hr LC50 of 0.9 ppm. This test followed the guideline "The Committee on Methods for Toxicity Tests with Aquatic Organisms 1975. Methods for acute toxicity tests with fish, macro-invertebrates, and amphibians. U.S. Environmental Protection Agency, Ecological Research Series, EPA-600/3-75-009. 61 p".
Suprenant (1988) report an unbounded 96 hr LC50: >0.74 mg/L (the highest test concentration resulted in less than 50% mortality). This test followed an EPA/OTS guideline.
A number of other studies are available which cover a variety of aquatic invertebrate species and are used as supprting studies. LC50 values of >0.96 - 9.63 mg/L are reported.
