To What Extent is the Adriatic Sea Actually Burdened with Men-induced and Natural Inflow of Substances

Kopneni izvori zagađenja su polivalentni. Putem otpadnih voda atropogenog porijekla te rijekama i površinksim spiranjem unose se tokom godine goleme količine tvari u more. Među tim tvarima sedimenti su svakako najdominantniji. U radu se daje procjena unosa voda i sedimenata od strane antropogenih i prirodnih izvora na slivnom području Jadranskog mora te njihovo značenje za okoliš. Jadran spada u niskoenergetske sedimentacijske okoliše sa slabim transportom sedimenata, a kako isti imaju veliku moć vezivanja zagađivala na sebe, širenje zagađenja na veće udaljenosti je znatno umanjeno. Riječni unos sedimenata u more za redove veličina nadmašuje antropogeni unos. U radu je dat osvrt na demografsku naseljenost litorala istočne i zapadne obale Jadrana te značenje glavnih naselja u pogledu utjecaja na okoliš.Land-based sources of pollution are polyvalent. Effluents of human origin, as well as by rivers and surface ablution, huge quantities of substances are carried into the sea every year. The most dominant among them are sediments. This paper presents an assessment of inflow of waters and sediments from man-created and natural resources in the river basin of the Adriatic sea, and the impact they have on the environment. The Adriatic sea belongs to the low-energy sediment environments with the low-scale transport of sediments. Since they have a large capacity for binding the pollutants, spreading of pollution to wider areas is thereby significantly decreased. Inflow of sediments by rivers comparatively exceeds men-included inflow. The paper also includes a demographic survey of population densitiy of littorals on the east and west coast of the Adriatic sea, and the impact that the major towns have on the environment
