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. Oxygen consumption rate of the nymphs was measured, using a closed-cylinder technique and micro-Winkler titration. The animals showed significant increases in respiration with raised Al concentrations. The mayfly species Ephemera danica, which is restricted to the less heavily acidified region of South Sweden, was most affected… 

Aluminum accumulation in a lotic mayfly at low pH--a laboratory study.

The response of macroinvertebrates to experimental episodes of low pH with different forms of aluminium, during a natural spate

Abstract24 h experimental episodes were created in a soft-water stream in upland Wales, by the simultaneous addition at separate points of sulphuric acid, aluminium sulphate and citric acid. In an

Aluminium impact on freshwater invertebrates at low pH: A review

Addition of Al to streams has in some cases increased drift and death of mainly some "surface-dependent" species, but also some strictly benthic animals, while other studies do not record any change in neither drift, mortality nor biomass.

Acid-stress effects on stream biology

The mechanisms for the changes in individual, population and community levels include elevated hydrogen, aluminium and cadmium concentrations that affect ion balance and respiration in fish and invertebrates, but also various behavior patterns, and development stages, which are exemplified by increased occurrence of those green algae that indicate an increase in nutrients.

The effect of aluminum in soft water at low pH on oxygen consumption by the dragonfly Libellula julia Uhler

When subjected to a series of elevated Al and H+ concentrations spanning environmentally relevant levels, the dragonfly Libellula julia respired at a rate lower than the controls. This trend was

Toxicity and Accumulation of Al in the Acid Water of Small Lakes and Watercourses in Finnish Lapland

On the basis of a study of the hydrochemical regime and the status of benthic acidophobic species in the acidified watercourses and small lakes of Finnish Lapland, humic compounds are demonstrated to

It is suggested that freshly neutralized Al, i.e., Al in transition from ionic species in acidic waters to polymers or precipitating hydroxides after a rapid increase to pH ≥ 6.8, impaired oxygen consumption by D. magna in a repeatable, dose-dependent fashion.

Aluminum is Harmful to Benthic Invertebrates in Acidified Waters, but at What Threshold(s)?

Throughout many years of research into acidification effects, the contributing impact of increased levels of aluminum (Al), related to low pH, has been discussed and studied, especially for fish, but

The effects of stream acidity on benthic invertebrate communities in the south‐eastern United States

Results indicate that direct effects of pH and Al (affecting survival) were more important than indirect effects of food availability in determining changes in invertebrate community structure between the study sites.

Aluminum toxicity to fish in acidic waters

The simultaneous increase in Al concentration with elevated acidity must be considered to accurately assess the potential effect of acidification of surface waters on survival of fish populations.

Interference of aluminium and pH on the Na-influx in an aquatic insectCorixa punctata (IIIig.)

Some investigations concerning the impact of acid precipitation on aquatic biota, assess possible toxic effects of aluminium in relation to low pH. But those studies mainly refer to the survival of

Effect of calcium and aluminum concentrations on the survival of brown trout (Salmo trutta) at low pH

The results of experiments to determine the survival times of yolk sac fry of brown trout (Salmo trutta) in a range of pHs, calcium and aluminium solutions are described, and the relevance of the results to the field situation is discussed.

Effect of low pH on sodium regulation in two species of Daphnia

The net loss of sodium in soft water was due to both an increase in sodium outflux and a decrease in sodium influx, while in hard water the effect was primarily on sodium out flux.

Aluminium chemistry and acidification processes in a shallow podzol on the Swedish westcoast

Processes pertinent to soil acidification with special emphasis on the solution chemistry of A1, were studied in three adjacent small catchments on the Swedish westcoast, with mixed coniferous forest

Aquatic Invertebrates from the Smoking Hills, N.W.T.: Effect of pH and Metals on Mortality

Water from an acidic pond was markedly more toxic to crustaceans than water from an alkaline pond when both were adjusted to pH 4.2, and Elevated concentrations of aluminum may account for this additional toxicity of the...

Experimental Acidification of a Stream in the Hubbard Brook Experimental Forest, New Hampshire

Incident precipitation in the northeastern United States averages about pH 4 as a result of increased pollution from sulfuric and nitric acids. To determine the effect of this increased acidity on

Quantitative aspects of oxygen uptake by Gammarus (Crustacea, Amphipoda): a critical review

The review deals with quantitative, analytical aspects of oxygen uptake related to body size, temperature, oxygen content of water, salinity, water velocity, substratum and activity of Cammarus, and a theoretical model relates oxygen uptake to growth and life-span of individuals.

Physical, chemical, and biological consequences of episodic aluminum additions to a stream1

AlCl/sub 3/ was added to a second-order stream to simulate episodic increases in Al concentration during acidic snowmelt. Significant decreases in pH and DOC and accumulation of foam at the surface
