Hydrographic features are intensifying the effects of anthropogenic activity on the Baltic Sea. The main problem is eutrophication, which favors oxygen depletion and hydrogen sulphide formation in stagnant deep waters. Harmful substances under investigation in the Baltic Monitoring Program include chlorinated hydrocarbons (DDT, HCH, PCB), heavy metals (Hg, Pb, Cd) and petroleum hydrocarbons. The environmental situation seems to have improved in recent years because of protection measures recommended by HELCOM and the economic collapse of the countries fomerly behind the Iron Curtain.
