Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 2,   Pages 236-240 doi: 10.1007/s11783-008-0008-x

Abstract: The effect of dissolved oxygen (DO) concentration on nitrite accumulation was investigated in a pilot-scalethe average nitrite accumulation rate at 91%., but nitrite accumulation rate was still as high as 90%.From the 38th day the nitrite accumulation rate decreased to 15%–30% linearly.Until the 83rd day the nitrite accumulation rate began to increase to 80%.

Heavy metal accumulation and phytostabilization potential of dominant plant species growing on manganese

YANG Shengxiang,LIANG Shichu,YI Langbo,XU Bibo,CAO Jianbing,GUO Yifeng,ZHOU Yu

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 3,   Pages 394-404 doi: 10.1007/s11783-013-0602-4

Abstract: Screening plants that are hypertolerant to and excluders of certain heavy metals plays a fundamental role in a remediation strategy for metalliferous mine tailings. A field survey of terrestrial higher plants growing on Mn mine tailings at Huayuan, Hunan Province, China was conducted to identify candidate species for application in phytostabilization of the tailings in this region. In total, 51 species belonging to 21 families were recorded and the 12 dominant plants were investigated for their potential in phytostabilization of heavy metals. Eight plant species, , , , , , , , and accumulated much lower concentrations of heavy metals in shoots and roots than the associated soils and bioconcentration factors (BFs) for Cd, Mn, Pb and Zn were all<1, demonstrating a high tolerance to heavy metals and poor metals translocation ability. The field investigation also found that these species grew fast, accumulated biomass rapidly and developed a vegetation cover in a relatively short time. Therefore, they are good candidates for phytostabilization purposes and could be used as pioneer species in phytoremediation of Mn mine tailings in this region of South China.
