Measuring Low Level Concentrations of Trace Metals in Wet Deposition Samples
Katie Blaydes1 and Lee Green2
Trace metals are released into the environment via natural and anthropogenic processes. Metals such as Al, Mn, Fe, Cr, Ca2+ and K+ are indicative of soil contribution. The Earth’s crust is enriched with many of these elements and Aeolian dusts can efficiently transport some crustal elements and heavy metals. Non-crustal volatile metals, such as Cd, Zn, and Pb are characteristic of fuel combustion and metal smelting. The Central Analytical Laboratory (CAL) has come up with a method to measure low level concentrations in wet deposition samples via Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES).
