摘要
目的研究浙江沿海棒锥螺中的有机氯农药类化合物含量及其区域分布特征。方法以定点方式从浙江省内10个县(区)采集了棒锥螺,通过建立的海产品有机氯的GC-MS检测技术与统计学分析方法研究浙江沿海棒锥螺中OCPs含量及区域分布特征。结果浙江沿海棒锥螺体内中总有机氯含量的浓度范围为8.6 ng/g(湿重,象山)至26.1 ng/g(湿重,瑞安)。从∑OCPs区域分布特征来看,棒锥螺中总有机氯农药平均含量(ng/g)随区域呈现出不同的分布水平。瑞安的棒锥螺中有机氯含量最高,奉化、嵊泗、普陀和椒江的棒锥螺中有机氯农药的含量次之,岱山、象山和三门的棒锥螺中有机氯含量最低。10个采样点棒锥螺中各种的有机氯含量与13种有机氯农药总含量的区域分布特征基本一致。结论浙江省内不同县区的棒锥螺中总有机氯农药平均含量随区域呈现出不同的分布水平。通过棒锥螺体内有机氯农药的含量来表征海洋环境污染状况是一种较好的研究途径。
Objective To study the contents and distribution characteristics of organochlorine pesticides（OCPs） in turritella bacillum in coastal region of Zhejiang.Methods Turritella bacillum were collected from 10 counties（regions） of Zhejiang to detect the OCPs contents by GC-MS,and analyze the regional distribution characteristics by statistical method.Results The mean wet weight-based concentrations of total organochlorine pesticides（OCPs） in turritella bacillum ranged from 8.6 ng/g（wet weight,Xiangshan） to 26.1 ng/g（wet weight,Ruian）.Significant discrepancy in total concentrations of organochlorine pesticides（OCPs） residues was apparent among different areas in Zhejiang.The wet weight-based concentration of organochlorine pesticides（OCPs） was highest in Ruian,lower in Fenghua,Shengsi,Putuo,Jiaojiang,and lowest in Daishan,Xiangshan,Sanmeng.Regional distribution characteristics of total concentrations of organochlorine pesticides（OCPs） were resembling with the respective organochlorine pesticides（OCPs） in turritella bacillum in the coastal region of Zhejiang.Conclusion The average contents of total OCPs in turritella bacillum exhibited various distribution levels among different regions.It is an ideal way to characterize the marine environment pollution situation through OCPs contents detection in turritella bacillum.
