Dangerous compounds in the dredged material from the sea - Assessment of the current approach to the evaluation of contaminations based on the data from the Polish coastal zone (the Baltic Sea).

It has been shown that the current approach to the assessment of contamination in the sediments obtained during the dredging works in the Baltic countries indicates the presence of "non-contaminated" dredged material. The concentration limits of heavy metals, Polycyclic Aromatic Hydrocarbons (PAHs), Polychlorinated Biphenyls (PCBs) have been exceeded only in 1% of the samples obtained during the dredging works (2005-2015) within the Polish coastal zone. After 2008, no contaminated sediments have been found.

Managing dredged material in the coastal zone of the Baltic Sea.

This article deals with the legal and practical recommendations for the management of dredged material in the riparian countries of the Baltic Sea. The recommendations are contained in three conventions: LC, 2000. London Convention (1972), Convention on the Protection of the Marine Environment of the Baltic Sea area (Helsinki Convention) (1992), the OSPAR Convention (1972).
