An important consequence of acidification is the mobilization of Al from the edaphic to the aquatic environment. Elevated Al levels in acidic waters may be toxic to fish. Eggs, larvae, and postlarvae of white suckers (Catostomus commersoni) and brook trout (Salvelinus fontinalis) were exposed in laboratory bioassays to pH levels 4.2 to 5.6 and inorganic Al concentrations of 0 to 0.5 mg l−1. Aluminum toxicity varied with both pH and life history stage. At low pH levels (4.2 to 4.8), the presence… 

Aluminum Bioaccumulation and Toxicity to Daphnia magna in Soft Water at Low pH

Aluminum may be either harmful or beneficial to Daphnia magna (Straus) depending on pH and on the Al concentration in the water, and Mortality in the presence of Al and also at low pH was associated with a net loss of Na and Cl from the daphnids.

Influence of pH on aluminum toxicity in pumpkinseed sunfish (Lepomis gibbosus rafinesque).

Increased aluminum levels have recently been correlated yrith fish mortality in acidified lakes. The toxic response to Al in freshwater is variable and depends on pH moderated chemical speciation of

In situ toxicity tests of fishes in acid waters

Toxicity of waters within the North Branch of the Moose River to various life stages of lake trout (Salvelinus namaycush), brook trout (Salvelinus fontinalis), creek chub (Semotilus atromaculatus),

Sensitivity of Endemic Snake River Cutthroat Trout to Acidity and Elevated Aluminum

It is found that the native western cutthroat trout Oncorhynchus clarki is sensitive to even brief reductions in pH, and the most sensitive indicators of stress were loss of ions and reduced swimming in alevins, reduct...

Water quality modulation of aluminum toxicity to rainbow trout (Oncorhynchus mykiss) : biological and physiological approaches

approved: Lawrence R. Curtis Aluminum chemistry and toxicity are significantly affected by water quality. Due to concerns about aluminum mobilization from terrestrial to aquatic environments via acid

Some effects on the growth of brown trout from exposure to aluminium at different pH levels

When growth rates are correlated with the different aluminium species, calculated using thermodynamic equilibrium constants given in the literature, it appears that the Al(OH)2 + species is the most toxic, with a small contribution also coming from polymeric complexes.

Aluminium impact on respiration of lotic mayflies at low pH

Three species of stream-living mayfly nymphs were exposed to total inorganic (labile) monomeric aluminium levels of 0, 0.5, and 2.0 mg L−1 at pH 4.0 and 4.8 for 10 days, showing significant increases in respiration with raised Al concentrations.



Aluminum Toxicity to Brook Trout (Salvelinus Fontinalis) in Acidified Waters

Aluminum was identified as a primary toxicant present in acidic, snow-melt runoff and lakes in the Adirondack Mountain region of New York. Covariance analysis of water quality data from fifty three

Toxicity of Aluminum Hydroxide Complexes in Neutral and Basic Media to Rainbow Trout

Abstract Toxic effects of aqueous aluminum complexes in neutral and basic media to rainbow trout fingerlings were investigated under constantly flowing, controlled conditions of concentration, pH,

Acidification of the La Cloche Mountain Lakes, Ontario, and Resulting Fish Mortalities

The loss of populations of lake trout, herring, white suckers, and other fishes in Lumsden Lake was attributed to increasing levels of acidity within the lake, and an absence of fishes was also observed in nearby lakes.

Effect of aluminium speciation on fish in dilute acidified waters

Acidification of lakes and streams is a serious water quality problem in high elevation granitic ecosystems in the northeastern US1–3. An important consequence of acidification is the mobilisation of

Effects of sulfuric water pollutants on fertilization, embryonic development and larvae of the herring, Clupea harengus

Although the present study needs deepening through further and more detailed experiments, it can be said that the pollutants under consideration represent a danger to herring eggs and larvae at least up to a dilution of 1:32000.

The effects of dissolved zinc on the gills of the stickleback Gasterosteus aculeatus (L.)

Many acutely poisoned fish recovered in zinc-free hard water, regeneration of epithelia being accompanied by a temporary appearance of chloride cells on the secondary lamellae as well as the formation of membrane-bounded vesicles and dense accumulations of metabolites.

Effect of Lime Neutralized Iron Hydroxide Suspensions on Survival, Growth, and Reproduction of the Fathead Minnow (Pimephales promelas)

A comparison of data on survival, growth, and hatchability indicates that the safe level of suspended iron for fathead minnows presumably lies between the control and 1.5 mg Fe/liter.

Aluminum Leaching Response to Acid Precipitation: Effects on High-Elevation Watersheds in the Northeast

Combined results from areas of silicate bedrock in the United States and Europe suggest that aluminum represents an important biogeochemical linkage between terrestrial and aquatic environments exposed to acid precipitation.

Acidic Precipitation in South-Central Ontario: Recent Observations

High acid loadings are likely to lead to acidification of many lakes and streams in the forseeable future, and although it is not yet possible to estimate the time required for this to happen, there is already some evidence of declining buffering capacity in a few lakes.
