Assessment of risk to aquatic organisms using risk quotients based on measured environmental concentrations (MEC) and predicted no-effect concentrations (PNEC) ranged from no significant risk (for algae, daphnia and fish) to low potential for adverse effects (for algae and fish).]]> Tue 27 Jul 2021 10:43:43 SAST ]]> Occurrence, distribution and ecological risk assessment of organophosphorus flame retardants and plasticizers in sediment samples along the Vaal River catchment, South Africa. http://tutvital.tut.ac.za:8080/vital/access/manager/Repository/tut:6760 1) while TBOEP, TPhP, and TBP posed medium risk (0.1 < HQ < 1) with the remainder posing negligible risk (HQ < 0.01).
