Abstract
The effect of rapeseed oil methyl ether (RME) on cladocerans (water flea Daphnia magna Straus) and fish embryos and prolarvae (round goby Neogobius melanostomus (Pallas)) is investigated. It has been determined that, with the increase of RME content in the water, the decrease in the survival rate, fecundity, abundance, and biomass of Daphnia population is observed, as well as the decrease in the survival rate of round goby embryos and fry and in the linear and weight growth rate of the fry. RME did not produce any teratogenic effect on the round goby embryos and fry in the investigated range of concentrations 1,25–100,0 mg/L. Based on the experimental data, no observed effect and lowest observed effect concentrations of RME have been identified.
