The kinetic and thermodynamic solubilities of Roche (Ro) pharmaceutical compounds were determined by HPLC, titrimetry, and UV/Vis spectroscopy in aqueous buffers and in non-buffered systems. For kinetic solubility, a turbidimetric method that allows

The episodic acidification of three salmon rivers on the Quebec North Shore during spring snowmelt is shown to result mainly from increased inputs of organic acids rather than strong mineral acids. Appreciable mobilization of Al occurs during the spr

Acidification of freshwater environments (terrestrial, surface water, and freshwater sediment) can significantly affect the geochemistry of Al, Cd, Pb and Hg; for example, metal mobility within soils (Al, Cd), the relative distribution of dissolved m
