“…Baker and Christensen 1991). It has been proposed a range in ANC limit for the survival of young brown trout in acidified Scottish streams, depending on the concentration of toxic inorganic Al (McCartney et al 2003). This is consistent with that found in the present study.…”

A regional data set on water chemistry from 1995 was used to set critical values for the survival of brown trout in Norwegian lakes (n = 790) in relation to pH, inorganic Al and acid neutralizing capacity (ANC). ANC was estimated both traditionally (ANC trad ) and modified by treating one-third of the dissolved organic matter as part of the strong acid anions (ANC mod ). The threshold value to avoid fish damage (ANC limit ) was compared with that found in a similar study from 1986. Brown trout populations were categorized as unaffected, damaged or extinct on the basis of questionnaires. In 1995, threshold values to avoid fish damage on the basis of ANC trad and ANC mod were 67 and 48 leq l -1 , respectively, compared with 20 and 8 leq l -1 , respectively, in 1986. The higher ANC limit found for the data from 1995 is probably caused by a lower pH and a higher inorganic Al concentration at a given ANC value in 1995 than in the 1980s. ANC limit was highly related to organic carbon concentrations in the study lakes, being estimated at 33, 73 and [100 leq l -1 for three different TOC categories (\2 mg C l -1 , 2-5 mg C l -1 and [5 mg C l -1 ). These differences in ANC limit are due to lower pH and higher concentrations of inorganic Al in humic lakes than in clear water lakes at the same level of ANC. It is suggested that the change in ANC limit for fish in acidified lakes is linked to increased concentrations of TOC in recent years.

“…The basis for relating changes in water chemistry to effects on fish populations was established from a UK wide survey of biological and chemical records (Juggins et al, 2001;McCartney et al, 2003) and a study of 1000 Norwegian lakes (Lien et al, 1996). These studies suggested that an ANC of zero represented a 50% probability of damage to a brown trout population and an ANC of 20 reflected 95% protection of the brown trout from damage (Lien et al, 1996).…”

“…This problem of surface water acidification is linked to the emission of acidic oxides of sulphur (S) and nitrogen (N) mainly from the burning of fossil fuels as well as reduced forms of N from agricultural production (NEGTAP, 2001). The main concern over increased acidity lies in its impact on aquatic biology; it has been found, to affect fish adversely (Lien et al, 1996;Juggins,2001;McCartney et al, 2003), invertebrates (Raddum and Skjelkvale, 2001;Raddum and Fjellheim, 2003) and phytoplankton (Findlay, 2003). Further, impacts on bird populations have also been inferred (Ormerod and Tyler, 1989).…”

The MAGIC (Model of Acidification of Groundwaters in Catchments) model has been calibrated to three acid sensitive regions in the UK: Galloway, the South Pennines and Wales. These calibrations use the best available data for surface water, soil and deposition, from several UK data bases and regional sampling programmes. The model is capable of reproducing observed base cation and acid anion concentrations as reflected by a close match between observed and simulated acid neutralising capacity (ANC). Predictions to 2016 under currently agreed emission reductions, the Gothenburg Protocol, show that ANC greater than zero will be achieved at 100%, 86% and 100% of sites in Galloway, the Pennines and Wales, respectively. This indicates the potential for biological recovery and a return to good status although chemical conditions remain some way from simulated pre-acidification conditions. In the longer term, beyond 2036 (20 years after compliance with the Gothenburg protocol), the model indicates that increased N leakage to surface waters may cause deterioration in the chemical status.

“…The negative effect of aluminium on fish has been described (Lydersen et al 1990;Gensemer and Playle 1999;McCartney et al 2003;Monette and McCormick 2008). Aluminium toxicity depends on water pH, and on the concentration of calcium and organic substances (Freda 1991;Wauer and Teien 2010).…”

ABSTRACT:Contamination of Pansky Pond, in March 2013, with 119 mg/l aluminium, and 87 mg/l iron by acidic (pH 3.17) inflow from a nearby quarry caused fish die-off, while exhibiting symptoms of suffocation. Transformation of soluble forms of aluminium and iron into insoluble forms occurred on fish gill where the content of aluminium and iron was 100-fold and 12-fold, respectively, that found in control fish in an unaffected pond. In addition to insoluble aluminium and iron, gills showed presence of iron bacteria. Histopathology was characterised by expression of reactive processes and regressive alterations resulting in gill tissue necrosis. Impairment of the excretory function of gills was reflected in significantly (P < 0.01) higher concentrations of ammonia in the blood plasma of exposed fish compared to the control. Damage to parenchymatous tissues (kidney, liver, spleen) of the exposed fish was manifested as dystrophic alterations, higher aluminium and iron content, and enhanced activity of transaminases in blood plasma compared to the control.
