Critical load exceedance and damage to fish populations
(NIVA-rapport;2900, Research report, 1993)To examine the relationship between the critical load exceedance and the damage to fish, the data for fish damage and water chemistry for 1000 lakes in Norway was used to derive the probability of damage to fish populations ... -
Dynamic Modelling of Surface Waters: Impact of emission reduction - possibilities and limitations (ICP Waters report 70/2002)
(NIVA-rapport;4598, Research report, 2002-12)Dynamic models provide an extension to critical loads by predicting the timescale of chemical recovery to emission reductions. They can also be used to determine the deposition levels required to achieve a prescribed target ... -
Effects of year-to-year variations in climate on trends in acidification (ICP Waters report 57/2001)
(NIVA-rapport;4328, Research report, 2001-01)Climatic variations potentially mask long-term trends in acidification of surface waters. High inputs of seasalts due to severe storms can cause temporary decreases in ANC. Temperature and moisture may affect nitrate ... -
