Main concerns for the Baltic Sea
{"Image DocumentName": "Main concerns for the Baltic Sea", "Image ImageDescription": "Eutrophication. Pollution by hazardous substances. Maritime activities. The Baltic Sea is the largest body of brackish water in the world. Salinity is much lower than the ocean s and only a small number of marine and freshwater species have been able to adapt to its brackish water, which makes the food web particularly vulnerable to external pressures. Additionally its water exchange is slow - a water residence time is years, which means that the pollution remains in the marine environment for a long time. Large parts are normally ice-covered during the winter, which in addition to shallowness and narrowness, make a navigation in the Baltic Sea difficult. The four main concerns for the environment of the Baltic Sea are eutrophication, pollution by hazardous substances, impact of maritime activities and loss of biological diversity. Loss of biological diversity.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
