摘要：

Concentrations of particulate and dissolved Fe and Mn were determined in samples collected from the St. Lawrence River near Québec City from fall 1982 to spring 1985. The results show a strong seasonality in metal concentrations. The seasonal variations of the two elements can be summarized as the superimposition of two cyclical phenomena. A sinusoidal variation probably reflects an oxidation process occurring at the source of the river. The other pattern, a sharp transient signal, is related to some event occurring during snowmelt. © 1990.
