“…Thus, direct and indirect effects of low pH on mortality and emigration are unlikely mechanisms for partitioning of brook trout and brown trout along pH gradients because they would also affect brook trout and occur at lower pH values than the thresholds we observed. Decreased primary productivity resulting from low pH (e.g., Tease and Coler 1984) would not be expected to favor one species over another in and of itself, but it may intensify competition for food.…”

Elevation and stream slope are abiotic gradients that limit upstream distributions of brook trout Salvelinus fontinalis and brown trout Salmo trutta in streams. We sought to determine whether another abiotic gradient, base-flow pH, may also affect distributions of these two species in eastern North America streams. We used historical data from the Pennsylvania Fish and Boat Commission's fisheries management database to explore the effects of reach elevation, slope, and base-flow pH on distributional limits to brook trout and brown trout in Pennsylvania streams in the Appalachian Plateaus and Ridge and Valley physiographic provinces. Discriminant function analysis (DFA) was used to calculate a canonical axis that separated allopatric brook trout populations from allopatric brown trout populations and allowed us to assess which of the three independent variables were important gradients along which communities graded from allopatric brook trout to allopatric brown trout. Canonical structure coefficients from DFA indicated that in both physiographic provinces, stream base-flow pH and slope were important factors in distributional limits; elevation was also an important factor in the Ridge and Valley Province but not the Appalachian Plateaus Province. Graphs of each variable against the proportion of brook trout in a community also identified apparent zones of allopatry for both species on the basis of pH and stream slope. We hypothesize that pH-mediated interspecific competition that favors brook trout in competition with brown trout at lower pH is the most plausible mechanism for segregation of these two species along pH gradients. Our discovery that trout distributions in Pennsylvania are related to stream base-flow pH has important implications for brook trout conservation in acidified regions. Carefully designed laboratory and field studies will be required to test our hypothesis and elucidate the mechanisms responsible for the partitioning of brook trout and brown trout along pH gradients.

Discharges from historic and current coal mines frequently generate waters low in pH (<3), high in heavy metals (e.g. Fe, Al) and cover streambeds in metal precipitates. The present study investigated periphyton communities at 52 stream sites on the West Coast, South Island, New Zealand, representing a range of impacts from acid mine drainage (AMD). Taxonomic richness was negatively related to acidity and metal oxides and biomass was negatively correlated with metal oxides, but positively related to acidity. Streams with low pH (<3.5) had low periphyton richness (14 taxa across all sites) and were dominated by Klebsormidium acidophilum, Navicula cincta and Euglena mutabilis. As pH increased, so did taxonomic richness while community dominance decreased and community composition became more variable. Canonical correspondence analyses of algal assemblages revealed patterns influenced by pH. These findings indicate that streams affected by AMD possess a predictable assemblage composition of algal species that can tolerate the extreme water chemistry and substrate conditions. The predictability of algal communities declines with decreasing stress, as other abiotic and biotic factors become increasingly more important.

“…The imarily due to the function of coal's sulphur content, such as highly sulphur rich coals normally have low pH values poor coals produce more pH neutral runoff [9,33].

In this study, the soil and water samples were analyzed to evaluate the effects of coal stockpile on soil and water quality at Haluaghat Upazilla, Mymensingh, Bangladesh. As a natural resource, coal has potential contributions to the development of economics of a country but coal storage deteriorates surrounding surface and ground water and soil quality in different ways. Besides, it has significant impacts on the arable lands and water catchments. The analyses of 10 soil and 10 water samples (5 samples from ground water and 5 samples from surface water) were collected at 0 m, 200 m, 500 m and 700 m distance from the coal storage area were carried out using standard methods. The pH, electrical conductivity (EC), organic matter (OM), macronutrients (N, P and K) and heavy metals (Lead and Cadmium) were analysed for soil samples and for water samples pH, EC, macronutrients (P and K), heavy metals (Pb and Cd) were analysed. From the results, it was observed that most of the value of soil and water quality components were higher at close to the coal stockpile area and gradually decreased with distance. Soil pH value showed a decreasing trend (5.2 to 3.2) with increasing distances from the coal storage area; whereas water pH increased gradually with increasing distances from the coal storage area. Soil OM content was found highest at the coal storage area, which decreased gradually with increasing distance. The content of soil N, P, K was also recorded highest at the coal storage area which followed decreasing trend with increasing distance. The content of Pb and Cd in soil adjacent to coal storage area was higher compared to distant areas (500-700 m) in paddy field. The soil quality might be deteriorated due to coal stockpile effluents. The effluents from the coal stockpile should be treated before it is discharged to soil or water.
