Bollman, M., W. Buane, S. Smith, K. DeWhitt, AND L. Kapustka. REPORT ON ALGAL TOXICITY TESTS ON SELECTED OFFICE OF TOXIC SUBSTANCES (OTS) CHEMICALS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-90/041 (NTIS PB90212606).

Description:

Algal (Selenastrum capricornutum) assays were performed on 11 chemicals selected from a larger list of candidate chemicals provided by the EPA's Office of Toxic Substances (OTS). imited chemical analysis of those chemicals that could be tested readily at ERL-C was performed in support of the bioassays. f the 11 chemicals tested, two (tetraethyl ammonium chloride and butyl mercaptan) were judged non-toxic to the algae by virtue of the calculated EC50 exceeding 1000 mg/L. hree chemicals were extremely toxic (EC50 < 10 mg/L; methyl vinyl ketone, octylamine, and phthalic anhydride); three were highly toxic (EC50> l0mg/L but lOO mg/L but <1000 mg/L; glyoxal, sodium dodecylbenzenesulfonate, and glycidol). his work contributes to the toxicity data base assembled on these chemicals. reviously, algal toxicity information was lacking for these compounds.
