Diel Cycling of Trace Metals in Streams

Information on studies of the diel cycling of trace metals in streams. USGS scientists and the colleagues have show that the concentrations of many ptrace elements (such as arsenic, cadmium, copper, manganese, zinc) in streams can vary over a large range (up to 500 percent) during a 24-hour period.
