摘要
研究了菜籽油甲基醚(RME)对肢纲动物(水蚤Daphnia magna Straus)和鱼类胚胎及幼鱼(圆虾虎鱼Neogobius melanostomus)的影响。结果表明，随着水体RME含量的增加，水蚤种群的存活率、繁殖力、丰度和生物量下降，圆虾虎鱼胚和鱼苗的存活率下降，鱼苗的线性生长率和重量生长率下降。RME在1、25 ~ 100、0 mg/L的浓度范围内对圆虾虎鱼胚胎和鱼苗均无致畸作用。根据实验数据，没有观察到RME的效应和最低观察到的效应浓度。
Assessment of the toxic effect of rapeseed oil methyl ether on cladocerans and fish
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.
