Abstract

Experiments simulating spring acidic snowmelt episodes were conducted to determine the effects of short-term inputs of H + and Al on the chemistry and biology of a poorly buffered mountain stream. HCl and AlCl 3 were added in separate experiments to first- to third-order reaches of New Hampshire stream. Fluctuating Al concentrations in low-order streams at a pH range of 4.5-5.5 may alter the biology and geochemistry of poorly buffered waters. -from Authors
