Electronic products such as semi-conductor, computer, and mobile phone are major high-tech industry in Taiwan. Emerging contamination elements (ECEs) are used in these industrial processes and become potential contaminants in soils and waters through wastewater and solid waste disposal. In ECEs, gallium (Ga) and thallium (Tl) are essential elements in the raw materials for making these electronic products. However, Ga and Tl have not been paid attention yet clearly in the agro-environment and food chain. This study investigated 296 soil horizon samples of 84 profiles from Taiwanese rural lands with different parent materials to measure total Ga and Tl in these soils for the purposes of establishing baseline concentrations and exploring vertical distribution of ECEs in the soils. The experimental results show that Ga and Tl ranged in 3.12-21.4 mg/kg and 0.08-1.88 mg/kg, respectively. The mean of Ga was 7.50 mg/kg and that of Tl was 0.19 mg/kg. Ga and Tl show irregular trend with soil depth in all profiles, and thus there was no significantly difference in the mean values of Ga and Tl between horizons. According to linear correlation between ECEs and soil properties, Ga significantly and positively correlated with Tl (r=0.38, p<0.01). In addition, Ga and Tl significantly and positively correlated with free Fe oxide and clay but negatively correlated with pH in the soils. These correlations demonstrated that Ga and Tl co-existed and they were predominately fixed in the clay and Fe oxide fractions in the soils. Hence, we need more studies to evaluate their mobility and bioavailability for the biogeochemical processes and human health assessment by using selective extraction and bioassay in the future.
