摘要: If oil sands process-affected water (OSPW) is to be returned the environment, a desire that it not adversely affect aquatic life. We investigated whether relevant model fish (rainbow trout, Oncorhynchus mykiss) could detect OSPW using its olfactory sense (smell) and exposure would result in behavioral changes. also ozonation of OSPW, which lowers concentration organic compounds attributed with toxicity (naphthenic acids), ameliorate any observed adverse effects. found regardless ozonation, evoked tissue responses similar those expected natural odorants, suggesting smell OSPW. In 30 min exposures, food odorant pheromone were reduced degree by again ozonation. However, within minutes cessation. contrast, longer (7 d) remained impaired, but ...
