The objective of the Balthazar project was to assess the potential sources of nutrient loading from all types of large animal farms in the Kaliningrad and Leningrad regions and to perform risk assessment of nutrient leaching from the livestock farms into Baltic Sea.

This dataset consists of information and status of the main pollution sources within the Baltic Sea catchment area (the Pollution Hot Spots). The HELCOM pollution Hot Spots were idenitified in 1992 by the HELCOM Joint Comprehensive Action Programme (more information is available on www.helcom.fi). The current status of active and cleaned hot spots is available https://helcom.fi/action-areas/industrial-municipal-releases/helcom-hot-spots/.
