摘要
在水温18-20℃下,采用静水和半静水式生物毒性试验法,研究了聚乙烯醇、环氧丙烷、丙烯酸和异戊二烯对体质量(0.19±0.01)g的凡纳滨对虾幼虾和体质量(4.48±1.03)g的褐牙鲆幼鱼的急性毒性。结果表明,4种化学品对凡纳滨对虾幼虾的24h半致死质量浓度分别为3823.90、119.90、376.90、28.36mg/L,48h半致死质量浓度分别为3368.70、92.28、280.70、26.60mg/L,72h半致死质量浓度分别为3085.30、68.58、193.00、25.33 mg/L,96h半致死质量浓度分别为2971.10、60.90、122.60、25.33mg/L,安全质量浓度分别为297.10、6.09、12.26、2.53mg/L,毒性依次为:异戊二烯(中毒)〉环氧丙烷(中毒)〉丙烯酸(低毒)〉聚乙烯醇(低毒)。环氧丙烷、丙烯酸和异戊二烯对褐牙鲆幼鱼的24h半致死质量浓度分别为139.90、243.80、26.41mg/L,48h半致死质量浓度分别为137.20、236.00、26.41mg/L,72h半致死质量浓度分别为132.90、229.00、26.41mg/L,96h半致死质量浓度分别为130.60、225.40、26.41mg/L,安全质量浓度分别为13.06、22.54、2.64mg/L,毒性依次为:异戊二烯(中毒)〉环氧丙烷(低毒)〉丙烯酸(低毒)。本试验结果可为4种化学品对海洋生物生态毒理学研究及应用提供参考。
Acute toxicity of polyvinyl alcohol, propylene oxide, acrylic acid and isoprene to juvenile Pacific white leg shrimp Litopenaeus vannamei with body weight of (0.19±0.01) g and bastard halibut Paralich- thys olivaceus with body weight of (4.48±1.03) g was studied at water temperature of 18--20 ~C by static and semi-static bioassay. It was found that LCs0 of polyvinyl alcohol, propylene oxide, acrylic acid and iso- prene to juvenile Pacific white leg shrimp was 3823.90, 119.90, 376.90 and 28.36 mg/L for 24 h, respec- tively, 3368.70, 92.28, 280.70 and 26.60 mg/L for 48 h, 3085.30, 68.58, 193.00 and 25.33 mg/L for 72h, and 2971.10, 60.90, 122.60 and 25.33 mg/L for 96 h, with safe concentration of 297. 10, 6.09, 12.26, and 2.53 rag/L, indicating the toxicity descendant order of isoprene (moderate toxicity): propylene oxide (moderate toxicity):〉 acrylic acid (low toxicity):〉 polyvinyl alcohol (low toxicity). The LCs0 of propylene oxide, acrylic acid and isoprene to bastard halibut juveniles was shown to be 139.90, 243.80 and 26.41 mg/L for 24 h, respectively, 137.20, 236.00 and 26.41 mg/L for 48 h, 132.90, 229.00 and 26.41 mg/L for 72 h, and 130.60, 225.40 and 26.41 mg/L for 96 h, with safe concentration of 13.06, 22.54 and 2.64 mg/L respectively, indicating the toxicity descendant order of isoprene (moderate toxicity):〉 propylene oxide (low toxicity) acrylic acid (low toxicity). The findings may provide the reference to ec- ological toxicology research of polyvinyl alcohol, propylene oxide, acrylic acid and isoprene to marine or- ganisms.
