Determination of transition metals in size-classified rain samples by atomic absorption spectrometry

Atomic Absorption Spectrometry (AAS) is used for the analysis of size-classified rain drops. Principal relationships between concentration and radius are given. Significant differences are found for Fe and Zn on the one hand and for Pb and Mn on the other hand. This is due to different scavenging mechanisms caused by different sized aerosols for these two groups of elements.
