Abstract

It is proposed to use data on the hydrocarbon content in phytoplankton contained in a studied water sample to calculate the biogenic background of hydrocarbons, without which the assessment of the degree of oil pollution of aquatic ecosystems would be incorrect. Algae were grown in sterile flasks to accumulate the biomass required for analysis. The amount of hydrocarbons isolated from lipid fractions of different algal species by thin layer chromatography varied from 0.004 to 0.007 mg per 1 mg of phytoplankton. The lipid content varied from 4.5 to 6.2% in different phytoplankton species; the concentration of hydrocarbons was 8–11% of the total lipid weight. Depending on the phytoplankton species, the composition of paraffin hydrocarbons was dominated by C₁₇, C₂₁, C₂₅, C₂₉, and C₃₁ odd n-alkanes.

亚速海和黑海浮游植物中大量物种的脂质部分中的碳氢化合物组成

摘要

建议使用所研究的水样中所含浮游植物碳氢化合物含量的数据来计算碳氢化合物的生物背景，否则，对水生生态系统的油污染程度的评估将是不正确的。藻类在无菌烧瓶中生长，以积累分析所需的生物量。通过薄层色谱法从不同藻类的脂质馏分中分离出的碳氢化合物的量范围为每1 mg浮游植物0.004至0.007 mg。不同浮游植物种类的脂质含量从4.5％到6.2％不等。碳氢化合物的浓度为脂质总重量的8-11％。根据浮游植物的种类，石蜡烃的组成主要由C ₁₇，C ₂₁，C _25决定。，C ₂₉和C ₃₁奇数正构烷烃。
