Sedimentary hydrocarbons have been studied quantitatively and qualitatively in 11 coastal stations located in the Gulf of Fos (French Mediterranean coast). Hydrocarbon levels ranged from 10 to 260 mg kg(-1) sed. dry weight. A new parameter "NAR" (Natural n-alkane ratio) is proposed to evaluate the contribution of terrestrial inputs of hydrocarbons in the sediments. The origins of hydrocarbons are multiple: terrestrial inputs, biogenic, pyrolytic (industry emissions mainly steel and iron industries, ship and road traffic). Generally, the main source of contamination is not petroleum. Several ratios between parent polycyclic aromatic hydrocarbons show that the sources of hydrocarbons in the sediments are generally much more pyrolytic than petrogenic.
对位于福斯湾（法国地中海沿岸）的11个沿海站点的沉积碳氢化合物进行了定量和定性研究。碳氢化合物含量范围为10至260毫克/千克沉积物干重。提出了一个新参数“NAR”（天然正构烷烃比率）来评估沉积物中碳氢化合物陆地输入的贡献。碳氢化合物的来源多种多样：陆地输入、生物成因、热解（主要是钢铁工业、船舶和道路交通的工业排放）。一般来说，主要的污染源不是石油。母体多环芳烃之间的几个比率表明，沉积物中碳氢化合物的来源通常热解成因比石油成因多得多。
