摘要
采用急性实验的常规方法—死亡概率法,用甲醛及几种抗生素对刺参幼参的急性毒性试验,结果表明:甲醛、氯霉素、环丙沙星、盐酸土霉素对刺参幼参24h半致死浓度(LC50)分别为:15.4×10-6、146.9×10-6、173.6×10-6、263.4×10-6;48h半致死浓度(LC50)分别为:13.6×10-6、107×10-6、144.4××10-6、244.7×10-6;安全浓度(SC)分别为:3.18×10-6、17.03×10-6、29.97×10-6、63.35×10-6。
Acute toxicity of formaldehyde and some antibiotics to juvenile sea cucumber(Apostichopus japonicus) was determined by death probability. The results showed that the 24 h LC_(50) of formaldehyde, chloramphenicol, ciprofloxacin and oxytetracycline hydrochlorid was 15.4×10^(-6), 146.9×10^(-6), 173.6×10^(-6), and 263.4×10^(-6), respectively. The value of 48 h LC_(50) of formaldehyde, chloramphenicol, ciprofloxacin and oxytetracycline hydrochlorid was 13.6×10^(-6), 107×10^(-6), 144.4×10^(-6), and 244.7×10^(-6), respectively. The safe-concentration (SC) of formaldehyde, chloramphenicol, ciprofloxacin and oxytetracycline hydrochlorid was 3.18×10^(-6), 17.03×10^(-6), 29.97×10^(-6), and 63.35×10^(-6), respectively.
