Two 96 hr tests on Mysidopsis bahia yielded LC50s for benzyl butyl phthalate of >0.74 mg/L and 0.9 ppm.
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.
