Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2003 in different regions of Europe
Eastern Europe: Bulgaria (33), Estonia (43), Hungary (89), Lithuania (59), Latvia (51), Poland (89), Slovenia (21). Nordic countries: Finland (26), Sweden (90). Background concentrations of orthophosphate in rivers (about 10 micro g P/l) are shown to aid the assessment of the significance of the phosphorus concentrations. The time series comprise consistent data sets with no data gaps. The arithmetic mean of the station annual average concentrations was used in the regional aggregations.
