    Effects of brominated emerging flame retardants in juvenile rainbow trout

    In this study, the chronic effects of two emerging brominated flame retardants, 1,2-bis(2,4,6-tribromophenoxy)ethane(BTBPE) and 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB) were evaluated in diet exposed juvenile rainbow trout(Oncorhynchus mykiss). FIsh uptake was measured after 28-d of...

    Chronic effects of TBOEP in Daphnia magna

    In this study, Daphnia magna transcriptomic response was measured by microarray to evaluate sublethal effects of TBOEP as part of a multi-level biological approach including specific gene transcription measured by qRT-PCR, enzyme activity, and life-history endpoints (i.e., survival, growth, and...

    Benzotriazole UV-stabilizers effects in juvenile rainbow trout

    The objectives of the present study were to evaluate the chronixc effects of 2 BZT‐UVs alone and in a mixture, 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐bis(1‐methyl‐1‐phenylethyl)phenol (UV‐234) and 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐di‐tert‐pentylphenol (UV‐328), in juvenile rainbow trout (Oncorhynchus mykiss)...

    Chronic toxicity of flame retardants in aquatic organisms

    The toxicity and modes of action of prioritized flame retardants were evaluated in aquatic organisms. The effects of the organophosphorous-containing flame retardant tris (2-butoxyethyl) phosphate (TBOEP) were measured in Daphnia magna after chronic (21-d) and multigenerational exposure (3...

    Toxicity of benzotriazoles in aquatic organisms

    Acute and chronic toxicity and modes of action of benzotriazoles (BZTs) and benzotriazoles UV-stabilizers (BZT-UVs) were evaluated in freshwater invertebrates, algae, and fish. Gene transcription, life history (viability, growth, reproduction), and protein activities were measured after short and...
