龙凤湿地不同区域正在遭受不同程度的污染. 湿地中的水体流动性差, 一些链烷烃及非烃类污染物在表层沉积物中富集、沉积, 其中的部分有机污染物难以降解. 通过实验分析检测了链烷烃及非烃类污染物在龙凤湿地不同区块的含量和性质, 确定了污染物在环境中的迁移转化规律, 为有效控制龙凤湿地的污染提供了前提和依据.
The Longfeng wetland is being contaminated to different extents. Many paraffins and non-hydrocarbons contaminants are enriched and aggraded due to low liquidity of wetland water. In addition, some organic pollutants are difficult to be degraded in the anaerobic environment. The rules of migration and transformation in Longfeng wetland environment are confirmed by determining the content and properties of paraffins and nonhydrocarbons pollutants. The presented study provides the precondition and a basis for effective control of Longfeng wetland contamination.
