Border river catchments between Russia and Finland Rivers included in the sampling programme and parties carrying out sampling . The rivers Vuoksi, Hiitolanjoki, Rakkolanjoki, Urpalanjoki and Lake Nuijamaa (the Saimaa canal) . Southeast Finland Centre for Economic Development, Transport and the Environment (KAS-ely) and the Russian party (Neva - Ladoga Water Authority) take samples from the same rivers in their own side of the border between the countries, on the same days . Additionally Finland is monitoring water quality in the rivers Jänisjoki, Tohmajoki and Kiteenjoki, and from Russia to Finland falling Koitajoki. Measured variables . Measured parameters correspond to the ECE Transboundary Water Agreement Monitoring recommendations . Monthly measured: secchi depth, temperature, O2, oxygen saturation, pH, conductivity, suspended solids, turbidity, color, CODMn, BOD7, Tot-N, Tot-P, Fe, Mn, and Na . In addition 4 times a year: Zn, Ni, Pb, Cu, Cr, Cd, and Hg Tot-P and Tot-N loads from Finland to Russia in 2008-10 Tot-P Tot-N 200 12000 180 10000 160 140 8000 120 100 Tons 6000 Tons 80 60 4000 40 2000 20 0 0 Vuoksi Small rivers Vuoksi Small rivers Knuuttila 2013 Tot-P load from Russia into the Gulf of Finland in 2008-10 Tot-P (2008-2010), tons Lake Ladoga 1100 (+10 % flow) The River Narva 386 (2/3 of the total) The Luga 1465 (Russia official) Unmonitored area 130 (estimate based on 19 rivers; PRIMER) Rivers disch. into the Neva 600 (estimate based on 6 rivers; e.g. PRIMER) City of St. Petersburg 528 (Vodokanal, treated) City of St. Petersburg 298 (Vodokanal, untreated) Other direct sources 80 (Sosnovyi Bor, Vyborg and Viborgskaya Ppm) Load from Finland -56 (the River Vuoksi catchment) Total 4531 (official 5993, corrected 6323; Slide 6.)
