摘要
本文反映铜、锌两种重金属和甲胺磷农药对大鳞副泥鳅(Paramisgurnusdabryanus)胚胎发育和仔鱼成活的影响。得到了三种药物对大鳞副泥鳅胚胎的24hLC50及对仔鱼的24h、48hLC50和安全浓度。结果表明:三种药物均能不同程度的影响大鳞副泥鳅的胚胎发育和仔鱼成活;三者的毒性强度是铜大于锌、铜锌远大于甲胺磷;但仔鱼比胚胎对药物更敏感。
This paper reported the effects of copper, zinc and methamidophos on the embryo development and larva survival of loach paramisgurnus dabryanus. The 24h LC50 of the embryos and 24h, 48h, LC50, and safe concentration (Sc) of the larvae have been obtained. The results show that both the embryos and larvae could be influenced in some degrees by three toxicants toxic intensity of copper is higher than zinc, and both of them are much higher than methamidophos. In comparison with embryo, the larva is more sensitive for the those toxicants.
