Riverine inputs of nutrients, selected heavy metals and organic micropollutants to Norwegian coastal waters from 10 main and 145 tributary rivers have been monitored during 1995. The inputs from rivers not monitored as well as direct discharges to marine waters along the coast from Sweden to Russia have been estimated. According to the results, total annual nutrient load to coastal waters from landbased sources, is approximately 4000 tonnes of phosphorus and 105.200 tonnes of nitrogen. About 43 per cent of the phosphorus and 60 per cent of the nitrogen are inputs from the monitored rivers and tributaries. Most inputs of heavy metals are low, especially the riverine inputs of Cd, Pb and Hg. A few values of Cd and Pb are below the detection limits of the specific analysis, and about 50 % of the Hg-analyses except for the "Skagrrak- rivers", where more than 60 % of the Hg-values were above the detection limit. Most values of the different congeners of PCB were below the detection limit. The pesticide lindane is detected in most analyses in small amounts. Total load of this compound is estimated to about 107 kg. The largest yields from heavy metals comprise copper and zinc, with input estimates of 347 and 967 tonnes, respectively. Retention in the fjords is not included in the above mentioned values, which in several cases would reduce the actual load to open marine waters considerably. Statens forurensningstilsyn (SFT)

Riverine inputs of nutrients, selected heavy metals and organic micropollutants to Norwegian coastal waters from lO main and 145 tributary rivers have been monitored during 1994. The inputs from rivers not monitored as well as direct discharges to marine waters along the coast from Sweden to Russia have heen estimated. According to the results, total annual nutrient load to coastal waters from landbased sources, is approximately 4100 tonnes of phosphorus and 98100 tonnes of nitrogen. About 30 per cent of the phosphorus and 60 per cent of the nitrogen are inputs from the monitored rivers and tributaries. Most inputs of heavy metals are low , especially the riverine inputs of Cd, Ph and Hg. A few values of Cd and Pb are below the detection limits of the specific analysis, and about 50 % of the Hg-analyses except for the "Skagerrak-rivers" , where more than 60 % of the Hg-values were above the detection limit. Most values of the different congeners of PCB were below the detection limit. The pesticide lindane is detected in most analyses in small amounts. Total load of this compound is estimated to about 89 kg. The largest yields from heavy metals comprise copper and zinc, with input estimates of 237 and 905 tonnes, respectively. Retention in the fjords is not included in the ahove mentioned values, which in several cases would reduce the actual load to open marine waters considerably. Statens forurensningstilsyn (SFT)

Riverine inputs of nutrients, selected heavy metals and organic micropollutants to Norwegian coastal waters from 10 main and 145 tributary rivers have been monitored during 1993. The inputs from rivers not monitored as well as direct discharges to marine waters along the coast from Sweden to Russia have been estimated. According to the results, total annual nutrient load to coastal waters from landbased sources, is approximately 3680 tons of phosphorus and 93800 tons of nitrogen. About 34 per cent of the phosphorus and 55 per cent of the nitrogen are inputs from the monitored rivers and tributaries. Most inputs of heavy metals are low, especially the riverine inputs of Cd, Pb, and Hg. A few values of Cd and Pb are below the detection limits of the specific analysis. This is also the case for Hg except for the "Skagerrak-rivers", where 79% of the Hg-values were above the detection limit. Most values of different congeners of PCB were below the limit. The pesticide lindane is detected in most analyses in small amounts. Total load of this compound is estimated to about 87 kg. The largest yields from heavy metals comprise copper and zinc, with input estimates of 273 and 905 tons, respectively. retention in the fjords is not included in the above mentioned values, which in several cases would reduce the actual load to open marine waters considerably.

This report contains data from the 1991 monitoring of 155 Norwegian rivers and tributaries in accordance with requirements of the Paris Commission (PARCOM): i.e.riverborne inputs of selected substances (nutrients,heavy metals, PCBs and lindane) to Norwegian coastal waters. Runoff from about 75 per cent of the main land areas, and 94 per cent og the Skagerrak region, has been monitored. Discharges from areas not covered by the river monitoring stations, are estimated by use of specific activity- and runoff coeffisients. The Norwegian State Pollution Control Authority(SFT)

Riverine inputs to Norwegian coastal waters from 10 main and 145 tributary rivers have been monitored during 1991. The loading from rivers not monitored as well as direct discharges to marine waters along the coast from Sweden to Russia have been estimated. According to the results, total annual nutrient load to coastal waters from landbased sources, is approximately 3590 tons of phosphours and 8860 tons of nitrogen. About 40 per cent of the phosphorus and 60 per cent of the nitrogen are inputs from the monitored rivers and tributaties. Discharges of heavy metals and micropollutants are also included in the investigation. Most inputs of these substances are low, especially the riverine inputs of Cd, Pb and Hg. Most values of these substances are below the detection limits of the specific analysis, which also in the case for the differen congeners of PCBs. The herbicide lindane is detected in most analyses in small amounts. Total load of this compound is estimated to about 260 kg. The largest yields from heavy metals comprise copper and zinc, with input estimates of 356 and 1040 tons, respectively. Retention in the fjords is not included in the above mentioned values, which in several cases would reduce the actual to open marine waters considerably.
