Binding grid cells - Norway An evaluation
(NIVA-rapport;3942, Research report, 1998)The quality of the critical load data for so-called "binding grid cells" in Norway has been checked. These are the following EMEP-grids (150km x 150 km): 16,20 16,21 16,30 17,19 17,20 and 18,21. Critical loads have been ... -
Critical load of acidity to surface waters in South-central Ontario Canada I. Application of the Steady State Water Chemistry (SSWC) model
(NIVA-rapport;4427, Research report, 2001)The Steady-State Water Chemistry Model was applied to lakes in 5 regions in Ontario, Canada. Critical loads and exceedances calculated for the regions indicate that the portion of the lakes with exceedances dropped from ... -
Critical Loads, Target Load Functions and Dynamic Modelling for Surface Waters and ICP Waters Sites (ICP Waters report 83/2006)
(NIVA-rapport;5166, Research report, 2006-08)Critical load functions (CLF) for ICP Water sites estimated with the FAB model and based on recent data (2000-02) do not differ greatly from those based on earlier data (1992-94/5). The ICP Waters sites in Europe are largely ... -
Overskridelser av tålegrenser for forsuring og nitrogen for Norge – oppdatering med perioden 2007–2011
(NIVA-rapport;6448, Research report, 2012)Rapporten viser overskridelser av tålegrenser for forsuring av vann og jord, samt overgjødslingseffekter på vegetasjon, med avsetningsverdier for perioden 2007–2011. Disse avsetningsverdiene gir noe reduksjon i areal med ... -
Overskridelser av tålegrenser for overflatevann og skader på fiskebestander. (Critical load exceedances for surface waters and damage to fish polpulations)
(NIVA-rapport;3565, Research report, 1996)Tålegrensekart for tilførsler av sterke syrer til Norge og skader på fiskebestander er utarbeidet basert på underruter av enheten 0.5 grader lengde og 1.0 grader bredde. Den arealmessige utbredelsen av fiskeskader og ... -
Regional Lake Surveys in Finland - Norway - Sweden - Northern Kola - Russian Karelia - Scotland - Wales 1995 Coordination and Design
(NIVA-rapport;3420, Research report, 1996)The three Nordic countries Finland, Norway and Sweden decided to carry out a joint Nordic Lake Survey in the fall of 1995. A working group, supported financially by the Nordic Council of Ministers (NMR), prepared a common ... -
Target loads for acidification of Norwegian surface waters
(NIVA-rapport;5099, Research report, 2005)Target load is a logical extension of the critical load concept and incorporates the time delays in the chemical recovery from acidification. Calculations based on data from the Norwegian monitoring lakes and the dynamic ...
