Abstract: 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.

Key words: non-hydrocarbon, paraffins, pollutant, superficial sediment, Longfeng wetland
