Atomic Absorption Spectrometry (AAS) - IntechOpen
cdn.intechopen.comThe study of trace metals in wet and dry precipitation has increased in recent decades because trace metals have adverse environmen tal and human health effects. Some metals, such as Pb, Cd and Hg, accumulate in the biosphere and can be toxic to living systems. Anthropogenic activities have substantially increased trace metal concentrations in the

www.rsc.orgIf other elements such as chlorine are present, they will also be converted to combustion products, such as hydrogen chloride. A variety of absorbents are used to remove these additional combustion products as well as some of the principal elements, sulphur for example, if no determination of these additional elements is required.
