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) chronically exposed (for 28 d) through the diet. Chemical analyses were used to measure liver accumulation of the 2 compounds in exposed trout. Hepatic RNA‐sequencing and qRT-PCR were used to measure gene transcription levels in exposed fish.

Results were published in a scientific article that can be found here: https://doi.org/10.1002/etc.4676
