沈水植物による水中の環境ホルモン浄化に関する基礎的研究 FUNDAMENTAL STUDY ON ENDOCRINE DISRUPTERS PURIFICATION BY SUBMERGED AQUATIC VEGETATION
Access this Article
Phytoremediation that attracts the attention is an effective technology of removing endocrine disrupters in soils, ground water and surface water. In this study, the absorption experiment of 17β-estraziol (E2) and bisphenol A (BPA) using <I>Egeria densa</I> and the field survey in the Nikaryo-yosui were performed in order to investigate whether submerged vegetation in a river can apply to the phytoremediation of endocrine disrupters. The absorption experiment revealed that <I>Egeria densa</I> absorbed E2 and BPA. From the result of field survey, the reduction rate of E2 and BPA concentrations in the area with vegetation was larger than that in the area without vegetation. Moreover, <I>Egeria densa</I> in a river absorbed E2 and BPA, and possibly removed.
