摘要:

通过对中国近岸常见底栖双壳类毛蚶（Scapharca subcrenata）、紫贻贝（Mytilus edulis）急性和慢性毒性试验，运用Log-logistic模型及Weibull毒性效应阈值模型计算对苯二酚对2种受试生物的半致死效应浓度（LC₅₀）、非检测效应浓度（NDEC)及无观测效应浓度（NOEC）；分析慢性毒性试验对受试生物体质量、体长及消化腺超氧化物歧化酶（SOD）活性的影响。结果显示，对苯二酚对毛蚶、紫贻贝的LC₅₀分别为34.10和66.50 mg/L，NDEC分别为0.36和0.50 mg/L，NOEC分别为0.40和0.60 mg/L。慢性试验周期内受试生物体质量、体长的组内与组间差异不显著（P>0.1）；SOD酶活性仅在个别时间段对照组和处理组间存在显著差异（P<0.05）。

Abstract:

Typical chinese coastal benthic bivalve Scapharca subcrenata and Mytilus edulis were selected to carry out acute and chronic toxicity tests of hydroquinone. Log logistic and Weibull model were applied to determined the lethal concentration 50(LC₅₀), no detected effect concentration (NDEC) and no observed effect concentration(NOEC). Toxic effects of hydroquinone on the body mass, body length and digestive gland superoxide dismutase (SOD) of the 2 tested organism were detected and analyzed. The results showed that LC₅₀ of hydroquinone to Scapharcasubcrenata ,and Mytilusedulis were 34.10 and 66.50 mg/L, NDEC 0.36 and 0.50 mg/L, NOEC 0.40 and 0.60 mg/L, respectively. Result of the chronic toxicity tests showed that differences between groups and within groups of body mass and body length were not significant(P>0.1), activity of superoxide dismutase showed significant difference between grouops in certain period(P＜0.05).
