Executive Summary Regional Overview “Case studies of river and direct inputs of contaminants to the marine and coastal environment with focus on the anthropogenic and natural changes in the selected areas of the NOWPAP region” had been prepared by the decision of 7th and 8th POMRAC FPMs approved by the 15th IGM. The goal of this activity was to reveal the relationships between inputs of contaminants from the land-based sources and environmental changes in the adjacent coastal areas. The previous results of NOWPAP activities have shown that such relationships, especially in quantitative terms, could be found only for the selected areas where extensive data sets are available. Therefore, each NOWPAP member state proposed such case study area: Jiaozhou Bay in China, Dokai Bay in Japan, Masan Bay in Korea and Peter the Great Bay in Russia. Experts from the NOWPAP countries have presented data on these areas according to the format proposed by POMRAC Secretariat. These data as well as other published information on the selected areas, were compiled, analyzed and presented in this report. The goal of this report is to look at the environmental status and trends within some typical and/or important coastal localities of NOWPAP countries, and to correlate this information with the changes of river and direct inputs of contaminants to the sea from the adjacent watersheds. The structure of the report comprises brief description of geographical features of selected areas: major rivers, coasts, geomorphology, climate, landscape and land-use features, as well as reasons of the study areas choice. Socio-economic factors relevant to the scale of the anthropogenic pressure on the coastal environment within selected areas are also described: population and popu- lation density, GDP and types of economic activities, wastewater generation and wastewater treat- ment efficiency, etc. The efforts have been made to obtain data on the changes of anthropogenic pressure during the last 30-50 years.
