| Abstract: | The results of examining the concentrations of 16 major polycyclic aromatic hydrocarbons are given. The examined samples were taken in the territory of Leningrad province and in the eastern Gulf of Finland in different seasons. Two seasonal natural profiles of polycyclic aromatic hydrocarbons were constructed, conventionally, for the spring and the autumn. The dominating effect on the formation of the profile of polycyclic aromatic hydrocarbons is exerted by pyrogenous pollution sources in winter and petrogenic pollution sources in summer. |
