The distribution of hexachloroeyclohexanes （HCHs） and dichlorodiphenyltrichloroethanes （DDTs） in the surface sea- water and sediment of Jincheng Bay mariculture area were investigated in the present study. The concentration of total HCHs and DDTs ranged from 2.98 to 14.87ngL-l and were〈0.032ngL-1, respectively, in surface seawater, and ranged from 5.52 to 9.43 and from 4.11 to 6.72 ng g-l, respectively, in surface sediment. It was deduced from the composition profile of HCH isomers and DDT congeners that HCH residues derived from a mixture of technical-grade HCH and lindane whereas the DDT residues derived from technical-grade DDT and dicofol. Moreover, both HCH and DDT residues may mainly originate from historical inputs. The hazard quotient of α-HCH, β-HCH, γ-HCH and δ-HCH to marine species was 0.030, 0.157, 3.008 and 0.008, respectively. It was estimated that the overall probability of adverse biological effect from HCHs was less than 5%, indicating that its risk to seawater column spe- cies was low. The threshold effect concentration exceeding frequency of γ-HCH, p,p＇-DDD, p,p＇-DDE and p,p＇-DDT in sediment ranged from 8.3% to 100%, and the relative concentration of the HCH and DDT mixture exceeded their probable effect level in sediment. These findings indicated that the risk to marine benthos was high and potentially detrimental to the safety of aquatic prod- ucts, e.g., sea cucumber and benthic shellfish.

以受精1 h以内的日本对虾受精卵为实验对象,采用静水试验方法,研究了Zn、Hg、Cu、Pb、As、Cd和Cr 7种重金属对日本对虾胚胎发育的影响。结果表明,在实验浓度范围内,7种重金属中Hg、Cu对日本对虾胚胎发育毒性最大,其次是Zn、As、Cd,Pb和Cr无明显影响。Hg、Cu、Cd、As、Zn对日本对虾胚胎LC50值分别为:0.0177 mg·L-1、0.1070 mg·L-1、1.6057 mg·L-1、3.3682 mg·L-1、8.2644 mg·L-1,致死效应最低可观测效用浓度(LOEC)分别为0.0037 mg·L-1、0.0166 mg·L-1、0.1302 mg·L-1、1.1572 mg·L-1、2.1522 mg·L-1;抑制发育LOEC分别为0.0062 mg·L-1、0.0176 mg·L-1、0.4002 mg·L-1、1.9497 mg·L-1、0.0617 mg·L-1。随着Hg、Cu浓度的升高,胚胎孵化率不断下降,无节幼体死亡率不断上升,在Hg0.0256 mg·L-1浓度组中,胚胎48 h死亡率达到100%。以上结果说明,Hg、Cu等重金属的存在会延缓日本对虾胚胎的发育速度,随着重金属浓度的增加,滞育现象愈加明显,在Cu 0.32 mg·L-1浓度组中,未见无节幼体孵出。

高效氟吡甲禾灵(haloxyfop-P-methyl,HPME)是我国农业上大量使用的一种除草剂,因对入侵植物互花米草有明显的杀害作用,被推荐用于互花米草的化学防治.为了预防HPME在施用过程中带来的生态风险,本文在开展HPME对海洋生物的毒性测试与搜集现有毒性数据的基础上,推导了HPME的生态安全阈值.首先,选取8门13科本地海洋生物进行急性毒性试验,并通过查找现有毒性数据库与文献获得HPME对3门5科7种淡水生物的毒性数据.随后,采用物种敏感性分布(species sensitivity distribution,SSD)模型与物种敏感性排序法(species sensitivity rank,SSR)分别推导HPME的水质基准.结果表明:①HPME对安氏伪镖水蚤的96 h半数致死浓度(median lethal concentration,LC50)值最小,为0.107 mg/L;对牡蛎的96 h-LC50值最大,为47.111 mg/L.②采用SSD模型,基于13种海水生物以及7种淡水生物+13种海水生物两组急性毒性数据推导出HPME的水质基准分别为37.05和44.75μg/L.③利用SSR法基于两组数据推导出HPME的水质基准分别为39.43和41.65μg/L.该文构建了HPME的水生生物毒性数据库,推导了HPME的水质基准值,可为我国互花米草治理过程中HPME的安全使用限量提供科学依据.
