Active coastal marine environmental exploitation has given rise to another problem: marine litter. The period of time allowing to evaluate the change in the degree of the shore pollution with litter is that from 1999 till 2014. Litter can be classified both by qualitative and quantitative character. Regarding qualitative character litter is divided into organic substance (garbage, wood) and non-organic substance (glass, plastics, rubber, metal). As to the size there are three categories: small, middle, large. As to small litter it is still predominating in the litter structure of the shoreline pollution but its average amount has been decreased significantly. As to the litter distribution, it is mostly concentrated within the beach zone. It is thus natural to assume the land-based origin of the litter, such as litter brought by holiday-makers or introduced by nearby enterprises.展开更多
