In natural mixed-sulphide assemblages, galvanic interaction between stibnite and pyrite has been shown to increase the dissolution of stibnite, leading to enhanced antimony leaching. The objective of this study was to determine the impact of pyrite o

Models of metal adsorption have typically been developed and tested for soil components rather than whole soils and at cation concentrations higher than usual environmental conditions. This study investigates whether the non-ideal consistent competit

Soil leaching has been proposed as a way to reduce soil-spiking artifacts (i.e., increased acidity, metal solubility) that occur in soils amended with trace metal salts. Leaching metal-spiked samples prior to ecotoxicity testing is therefore expected

A research project on foliar and soil chemistry in declining sugar maple (Acer Saccharum, Marsh) stands was carried out in the Beauce-Megantic region of southern Quebec. Foliar nutrient concentrations in declining stands were low in P, K, and in some

The relationships between fluctuations in climatic conditions, forest productivity and elemental cycling were studied from 1994 to 1997 in a headwater catchment of the southern Laurentians dominated by sugar maple (Acer saccharum Marsh.) growing on p

Sulfate sorption and desorption as a function of pH were measured for six podzolic horizons from two forested watersheds of the southern Laurentians. The results showed a rapid increase in sulfate sorption with decreasing pH to a maximum sorption cap
