摘    要: 黄河三角洲沉积物中游离(气态和液体)烃含量为0.01~0.14 mg/g.它们富集在黏土粒级之中.沉积物中石油成因的烃类主要来自三角洲地区,热解成因的烃类主要来自黄河流域.黄河流域工业和民用煤不完全燃烧时所产生的多环芳烃应是黄河三角洲沉积物中热解成因烃类的重要来源.在遭受原油污染地区,原油可快速地被微生物降解.

关 键 词:沉积物  烃类  多环芳烃  生物降解

Abstract:The free (gaseous and liquid) hydrocarbons content in the sediment of the Yellow River delta ranges from 0.01 to 0.14 mg/g. They are enriched in the clay fraction of sediments. The petrogenic hydrocarbons come mainly from the delta area, while the pyrogenic hydrocarbons come mainly from the Yellow River drainage area. The polycyclic aromatic hydrocarbons produced from incomplete combustion of industrial and civil coals in the drainage area are the main sources of the pyrogenic hydrocarbons in the sediments of the Yellow River delta. The crude oil can be quickly biodegradaded in the oil polluted area.
