This paper deals with the acute and chronic toxic effect of Cu2+,Zn2+ r on survival rates,growth of the Neomysis awatschensis including the values of 24,48,72 and 96 h LC50,and safe concentration(SC) in seawate.
包括了Cu2+、Zn2+对黑褐新糠虾在24、48、72和96 h的半致死浓度(LC50),安全浓度(SC)和在生长、成活、繁殖等方面的影响。
The results showed the 48 h,72 h and 96 h LC50(median lethal concentration) values for trichlorfon against fingerling of Carassai.
根据试验期间死亡鱼数及死亡时间,用直线内插法计算各时间点的半致死浓度LC50并根据死亡鱼数研究pH值和温度对敌百虫毒性的影响。
It was found that the 24,48,72 h and 96 h median lethal concentration(LC50) values(95% confidence interval) of the phenol to the juveniles were 97(87-109),83(73-95),75(69-83)mg/L and 71(64-80)mg/L,respective.
结果表明:苯酚对中华鲟稚鱼24、48、72 h和96h的半致死浓度(LC50)及95%可信区间分别为97(87~109)、83(73~95)、75(69~83)mg/L和71(64~80)mg/L;Cu2+对中华鲟稚鱼的24、48、72 h和96 h的LC50及95%可信区间分别为0。
The study showed that tadpoles of Bufo Melanosticus,a specie widely distributed in South China,are highly sensitive to waste battery leaching and that the median lethal concentration decreases with the increase of time.
选用我国南方自然界中广泛分布的黑眶蟾蜍(Bufomelanosticus)的蝌蚪,通过研究废旧电池浸出物对蟾蜍蝌蚪致死率的影响,表明蝌蚪对废旧电池渗出液十分敏感;半致死浓度随着时间的增加而降低。
The grades were designed by equal space between logarithm, and the median lethal concentration was computed by Linear Regression.
浓度梯度按等对数间距设置,半致死浓度采用直线内插法进行计算。
