This article is not intended to be an instruction manual on water sampling. Rather, it presents current information concerning the sampling, sample handling, and storage procedures for trace metals in fresh, estuarine, and marine waters. “Trace metals” will refer not only to the transition metals but also those elements in groups IV-A, V-A, and VI-A which form covalent hydrides.
