This study investigated the characteristic distributions of heavy metals in rainwater, and the relationship between the concentrations of heavy metals and other chemical properties of the rainwater was also evaluated. Chemical properties of the rainwater varied between different raining periods and years. The volume-weighted mean of rainwater pH ranged from 3.9 to 6.7, and the individual volume-weighted means followed the order Zn > Pb > Cu > Cr > Ni > Cd. There were positive correlations between the major ionic components, such as Ca, Mg, and K, and the heavy metal concentrations of rainwater. The trends of monthly heavy metal concentrations showed higher values in July during 2011-2013. The order of average enrichment factors (EFs) was Cd > Pb > Cu > Zn > Ni > Cr; all of these were relatively higher than the EFs of natural components such as Fe, Mg and Ca. The overall finding of this study indicated that the concentration of dissolved trace metals can increase under the condition of acid rain.

Atomic absorption spectrometry (AAS) is one of the most often used techniques for the quantitative determination of elements in environmental materials at trace and ultratrace levels. AAS is an optical atomic spectrometric technique based on the measurement of the specific absorption originating from free nonionized atoms in the gas phase. To transfer the analyte to free atoms, different types of atomizer are in use, the flame and the graphite furnace types being the most often used. Typical detection limits of flame atomic absorption spectrometry (FAAS) are of the order of 1–100 µg L −1 , making it a perfect tool for the determination of minor and trace elements, at least for contaminated samples. Graphite furnace atomic absorption spectrometry (GFAAS), offering detection limits which are about a factor of 20–200 lower than for FAAS, is the standard method for many trace elements, especially for background values, and for unpolluted samples, such as fresh water and biological materials. AAS in its conventional configuration is a single‐element technique, which has to be used in a sequential mode when more than one element has to be determined. However, there are commercial instruments available that can be used for the determination of 6–8 elements simultaneously.
