Abstract: | The results of studying the hydrocarbon composition of organogenic bottom sediments of oil-polluted lakes and lakes of similar types remote from centers of anthropogenic activity are given. To correctly assess the oil pollution of organogenic materials one has to take into account the presence of native hydrocarbons in their composition and to choose the main criterion of oil pollution based on the presence of specific oil components not characteristic of aquatic ecosystems in their natural state. The most promising among such components are alkylbenzenes С15–С25, which slowly degrade under the conditions typical of northern aquatic ecosystems and can be retained for a long time by organogenic matrix. |
