Identification and ranking of the risky organic contaminants in the source water of the Danjiangkou reservoir

《环境科学与工程前沿(英文)》 2014年 第8卷 第1期   页码 42-53 doi: 10.1007/s11783-013-0499-y

摘要: The Danjiangkou reservoir was selected to provide the source water for the middle routes of the South to North Water Transfer Project, which has provoked many environmental concerns. To date, investigations of water contamination of the source water of the Danjiangkou reservoir with organic micro-pollutants have been limited. This study was conducted to identify and rank organic contaminants that pose risks in the Danjiangkou reservoir. To this end, the Chemical Hazard Evaluation and Management Strategies (CHEMS-1) approach was adapted to integrate the deconvolution technology of qualitative identifying contaminants for site-specific environmental matrices. The samples were screened for the presence of 1093 contaminants using deconvolution technologies and the hazard values of the identified contaminants were calculated using the adapted CHEMS-1 approach according to their hazardous properties and occurrence in source water. The results showed that 46 contaminants from 1093 targets were present in Danjiangkou water, 23 of which appeared at frequencies higher than 50%, and 15 of which were identified as priorities. Over half (53%) of the high-ranked contaminants were polycyclic aromatic hydrocarbons (PAHs), with chrysene ranked highest on the list. Health risk assessment of the top-ranked PAHs was conducted and revealed that cancer risks of PAHs detected in the source water of Danjiangkou to different populations ranged from 10 to 10 , indicating a low cancer risk to consumers. The results of this study indicated that the adapted CHEMS-1 approach was feasible for site-specific screening of organic contaminants to identify and rank potential priority pollutants.

摘要:

混凝土控制拆除是水电工程续建、扩建、再建项目施工中的重点与难点问题之一。通过系统分析混 凝土控制拆除的技术要求,总结了混凝土控制拆除施工常用方法的优点、适用条件和实施要点,建立了混凝 土控制拆除施工方法选择标准体系。同时,将该体系应用于南水北调中线丹江口大坝加高工程的施工实践 中,各项控制拆除工作实施效果良好。建立的混凝土控制拆除施工方法选择标准体系和丹江口大坝加高工 程中的典型实例可供类似工程借鉴参考。
