Evaluation of Land Use Adaptation by Sequential Extraction of Soil Trace Elements at an Abandoned Gold and Copper Refinery Site in Northern Taiwan

This study site is located at an abandoned factory of mining, smelting, and refining gold copper in north Taiwan for more than one hundred years. The present used soil background investigation out the sequential extraction procedures arsenic to assess reutilization potential brownfields site. upper limit concentration was 300 mg/kg 700 copper. within mainly immobile fraction, such as forms fixed by layer silicates, that were very low risk environmental releases. sedimentation basin, refinery, refinery mobile fractions acid extractable, reducible, oxidizable with higher release risk; therefore, except merely those three zones entire releases copper, risks trace elements are quite rest areas, land reuse without contact or plant non-edible plants possible. Therefore, response public demand opening part promote local tourism development, appropriate control isolation measures can be implemented prevent toxic from affecting human health through ingestion, skin contact, other exposure pathways. In terms pollution control, reducing dust inhalation also option efficiently reduce acceptable level achieve goal sustainable use contaminated
