Riverine inputs of nutrients and selected hazardous substances

Dataset description:

The dataset contains annually reported data on water flow, input of nutrients and selected hazardous substances to the Baltic Sea from monitored rivers and unmonitored areas within its catchment area. The data, obtained through national monitoring programmes, is reported by all Contracting Parties to the Helsinki Convention to the HELCOM Pollution Load Compilation (PLC-water) database. The data includes transboundary inputs from territories of countries located within the Baltic Sea catchment but not being Contracting parties to the Helsinki Convention, as measured on the borders of downstream countries. The data is quality assured and approved by Contracting Parties to HELCOM in accordance with the HELCOM Guidelines for the annual and periodical compilation and reporting of waterborne pollution inputs to the Baltic Sea (HELCOM PLC-Water Guideline).


Dataset content:

The dataset contains he following information: :

1. Source name. Name of river catchment or an unmonitored area.

2. Source code. Pollution Load Compilation (PLC) code of monitored river or an unmonitored area.

3. Country code. Code of country in the Baltic Sea drainage area. The following country codes are possible: DK; EE; FI; DE; LV; LT; PL; RU; SE; BY; UA; CZ; SL.

4. Sub-basin code. Code of the Baltic Sea sub-basin used in HELCOM assessment of inputs of nutrients and hazardous substances. The following sub-basin codes are possible: ARC; BAP; BOB; BOS; GUF; GUR; KAT; SOU; WEB.

5. Parameter. Parameters reported by the contracting parties to the Helsinki Convention to assess riverine inputs of nutrients and selected hazardous substances. : AOX; BOD5; BOD7; Cd; COD-Cr; COD-Mn; Cr; Cu; FLOW; Hg; Ni; NNH4; NNO2; NNO23; NNO3; NTOT; Oil; Pb; PPO4; PTOT; SPM; TOC; Zn. (tonnes/year or flow in m3/s).

6. Year of observation.

Country codes used in the dataset correspond to: BY - BELARUS, CZ - CZECH REPUBLIC, DK - DENMARK; EE - ESTONIA; FI - FINLAND; DE - GERMANY; LV - LATVIA; LT - LITHUANIA; PL - POLAND; RU - RUSSIA; SK - SLOVAKIA; SE - SWEDEN; UA - UKRAINE.

The Baltic Sea sub-basin codes used in the dataset are: ARC - ARCHIPELAGO SEA; BAP - BALTIC PROPER; BOB - BOTHNIAN BAY; BOS - BOTHNIAN SEA; GUF - GULF OF FINLAND; GUR - GULF OF RIGA; KAT - KATTEGAT; SOU - SOUND; WEB - WESTERN BALTIC.


Visualization:

The dataset can be retrieved from the HELCOM PLC-Water database and visualized utilizing an online user interface. The following filters are available to generate the dataset:

1. Source of input: monitored river, unmonitored area. Multiple selection possible

2. Country: BELARUS, CZECH REPUBLIC, DENMARK; ESTONIA; FINLAND; GERMANY; LATVIA; LITHUANIA; POLAND; RUSSIA; SLOVAKIA; SWEDEN; UKRAINE. Multiple selection possible.

3. Baltic Sea sub-basin: ARCHIPELAGO SEA; BALTIC PROPER; BOTHNIAN BAY; BOTHNIAN SEA; GULF OF FINLAND; GULF OF RIGA; KATTEGAT; SOUND; WESTERN BALTIC. Multiple selection possible.

4. Year (the first and the last years of the time series): 1995-20…

5. Parameter: AOX; BOD5; BOD7; Cd; COD-Cr; COD-Mn; Cr; Cu; FLOW; Hg; Ni; NNH4; NNO2; NNO23; NNO3; NTOT; Oil; Pb; PPO4; PTOT; SPM; TOC; Zn [tonnes/y, flow in m3/s]. Only one parameter can be selected.
