Proportion of classified water bodies in different RBDs affected by pollution pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)
See the EEA ETC/ICM technical report for more details and the methodology used for assessing pressures (EEA ETC/ICM, 2012a).
A water body is considered to be affected by pollution pressures if it is reported with the aggregated pressure type 'Point sources' and/or 'Diffuse sources' and/or any of the corresponding disaggregated pressure types (e.g. urban wastewater, industry emissions or agriculture diffuse pollution). Swedish surface water bodies are defined as not affected by diffuse pollution pressures if the only reported diffuse pollution pressure is airborne mercury contamination.
