Abstract

The article gives the results of studies of the concentration and composition of aliphatic hydrocarbons in suspension in surface water and in the surface layer of bottom sediments in April and September 2019 in Kerch Strait compared with other regions of the Black Sea. Notwithstanding the high concentrations of aliphatic hydrocarbons (especially, in the water of the strait itself, i.e., 110–160 µg/L and in sand sediments, i.e., 16–63 µg/g), the composition of alkanes was not of petroleum type because of the rapid transformation of petroleum hydrocarbons. The pollution of water and sediments in the strait manifested itself in a higher concentration of hydrocarbons in the composition of lipids and C_org, in the presence of naphthene-aromatic compounds in alkane composition, and in the predominance of phytane over pristine.

刻赤海峡水和底泥中的碳氢化合物

摘要

文章提供了与黑海其他地区相比，2019年4月和9月在刻赤海峡的地表水和底部沉积物表层悬浮液中脂肪烃浓度和组成的研究结果。尽管脂肪烃的浓度很高（特别是在海峡本身的水中，即110-160 µg / L，在沙子沉积物中，即16-63 µg / g），但烷烃的成分并非石油类因为石油烃的快速转化。海峡两岸的水和沉积物污染表现为脂质和C _org的碳氢化合物浓度较高。，烷烃成分中存在环烷烃-芳族化合物，并且植烷高于原始原料的情况。
