Pteris vittata L. subsp. vittata, a potential arsenic hyperaccumulator fern, growing naturally in the vicinity offly ash was analyzed for the concentration of nine heavy metals (Fe, Cu, Zn Ni, Al, Cr, Pb, Si, and As) from five different sites around of Kanti Thermal Power Station at Muzaffarpur in Bihar State, India. Metal accumulation in P. vittata was correlated with the level of pollution at five selected sampling sites. The results revealed significantly more accumulation of these metals in the above ground parts of the plant than the parts below ground. Statistical parameters such as the coefficient of variation (CV%) showed a higher for As, Cu, Cr, and a lower one for Fe, Ni, Al. There was high spatial variability in the total metal concentration at different sites. The present study confirmed that P. vittata is a heavy metals accumulator and that it is a highly suitable candidate for phytoremediation of metal contaminated wastelands.
凤尾蕨（Pteris vittata L. subsp. vittata）是一种潜在的砷超积累蕨类植物，自然生长在粉煤灰附近。本研究分析了印度比哈尔邦穆扎法尔布尔坎蒂火力发电站周围五个不同地点的凤尾蕨对九种重金属（Fe、Cu、Zn、Ni、Al、Cr、Pb、Si 和 As）的浓度。凤尾蕨对重金属的积累与五个选定采样点的污染水平有关。结果表明，与地下部分相比，这些金属在植物地上部分的积累显著增加。统计参数，如变异系数（CV%），对 As、Cu、Cr 较高，而对 Fe、Ni、Al 较低。不同地点的总金属浓度存在高度的空间变异性。本研究证实凤尾蕨是一种重金属积累植物，非常适合用于修复金属污染的荒地。
