Test organisms were collected from tundra ponds at the Smoking Hills, N.W.T. One of the ponds was alkaline (pH ), the other was acidified (pH ) as a result of natural SO2 fumigations.

Havas M, Hutchinson TC () Effect of low pH on the chemical composition of aquatic invertebrates from tundra ponds at the Smoking Hills, N.W.T., Canada.
Can J Zool – Google ScholarCited by: Ponds ranged in a base mean pH from to pH has been found to be an important factor influencing gastropod fauna. Neutral ponds support diverse communities, typical of small water bodies.
In two acidic pond types, snail fauna was different. Among the species characteristic for acidic ponds (pH Cited by: 3. In forest ponds of this study, the highest ammonia content was characteristic of the alkaline ponds (39 mg/l). The highest concentration of nitrates was found in ponds with the lowest pH (50 mg/l) as well as in the alkaline ponds ( mg/l).
Woodland ponds have a relatively high content of Fe (Spyra ).Cited by: 3. The acid-soluble measurement is expected to be useful for most metals and metalloids, thus minimizing the number of samples and procedures that are necessary.
The acid-soluble measurement does not require filtration of the sample at the time of collection, as does the dissolved measurement. Natural Resources Ecology Laboratory, Colorado State University. Collins: National Atmospheric Deposition Program. Gjessing, E., A.

However, the extrapolation of stream water chemistry to soil is difficult because of the complexity of hydrological pathways and chemical reactivity during water mixing.

Most soil comes ultimately from weathering of rocks, and is changed by both natural and human factors. Currently, human actions are moving as much soil as does wind and rain. Soil chemistry is affected by ground water, acid rain and various environmental factors.
