Despite oyster’s impressive filtering ability, oysters polluted by heavy metals remain. On the other hand, Taiwan excels in functional textiles, with antibacterial and deodorizing copper-zinc fiber. This study had farmed 10-cm oysters in Er-Ren with self-made basket for five months from October 2015 to June 2016. We then detect five kinds of heavy metals content in our samples, including copper, zinc, lead, cadmium, and arsenic with ICP-MS. The result shows less lead, cadmium and arsenic content in the oysters, and more copper and zinc content, which increments with time. Sided with the fact that regenerated fiber can detect heavy metals like copper, zinc and lead, we come to the conclusion that regenerated fiber, containing trace elements cleaning oyster extracts, can decontaminate, recycle and reuse metals. Skills or even a whole industry of environmental heavy metals remove are ready to be explored.
