...Marie E. DeLorenzox; Meagan Leatherbury; Jeannette A. Weiner; Alan J. Lewitus; Michael H. Fulton Algal species vary considerably in sensitivity to the commonly used herbicide atrazine, and it is hypothesized that several factors may contribute to species-specific sensitivity. In this study four...

... elevated expression of nitroreductase and O -acetyltransferase. They were shown to be highly sensitive to mutagenic nitro-compounds (e.g. 1-nitropyrene and 1,8-dinitropyrene) and, after metabolic activation by rat liver S9-mix, also to mutagenic amino-compounds (2-aminoanthracene). Furthermore, strains of...
