“…Further, selection of the ME A. wardii should be considered because study revealed that the response of ME was quite different from the Non-mining Ecotype of this species. ME showed less decline in biomass and less damage when subjected to Pb stress (Zou et al, 2010).…”

“…These fern also has suitable features for phytostabilization because of its well-developed root system, high biomass, and ability to maintain high content of Pb in its root tissue (Zou et al, 2010). Unlike the Pteris vitatta, A. wardii uses the method of phytostabilization.…”

“…Phytostabilization is a type of phytoremediation were the metals are sequestered in the roots and rhizosphere (Mendez and Maier, 2008). According to Zou et al (2010), they were able to identify a Mining Ecotype (ME) of A. wardii species growing in Lead-Zinc Mine tailings in Sichuan Province of China and was able to accumulate as much as 15, 542 ppm of lead in its roots. Further, selection of the ME A. wardii should be considered because study revealed that the response of ME was quite different from the Non-mining Ecotype of this species.…”

Post-mining activities in Samar left serious environmental issues. Albeit it is used to provide prosperity to its constituents, mining in the area brought with it negative impacts. Bagacay Mine, an abandoned mining area in the province was left with enourmous amount of heavy metals. This include As (6-693 ppm), Cu (9-5,279), Pb (22-354 ppm), Hg (1-5 ppm), Zn (<1-7,138 ppm) and Fe (5,900-373,500 ppm). The area was then reforested with Swietenia macrophylla, Leucaena leucocephala, Acacia mangium, Bambusa blumeana and Thysanolaena maxima but only 1 percent survived. This paper touches the nature and effects of the non-essential heavy metals and metalloids present in the area as well as the mechanism of phytoextraction. Additionally, tropical metallophytes which can be used for phytoremediation activities in the future were introduced and reviewed.

“…The ferns were separated into similar size plant segments composed of 5-6 fronds. Healthy plants of similar size were selected and cultured for 2 weeks in quartz sand with 1/10 Hoagland's solution, which was watered every 3 days (Zou et al 2011). …”

“…is a common perennial plant; specifically, a type of fern that grows in fascicles. It was found to have a high potential in accumulating high concentrations of lead (Pb) and Cd in roots at the contaminated sites in China, which may be useful for the phytostabilization of soils contaminated by these two metals (Zou et al 2011;Zhang et al 2012). However, there is little information available regarding the Cd uptake and distribution patterns in response to Cd stress in this plant species.…”

Athyrium wardii (Hook.) is a promising herbaceous plant species for phytostabilization of cadmium (Cd)-contaminated sites with large biomass and fast growth rate. However, little information is available on its tolerance mechanisms toward Cd. To further understand the mechanisms involved in Cd migration, accumulation and detoxification, the present study investigated subcellular distribution and chemical forms of Cd in the mining ecotypes and corresponding non-mining ecotypes of A. wardii via greenhouse pot experiment. Subcellular fractionation of Cd-containing tissues demonstrated that the majority of the element was mainly located in soluble fraction in cell walls. This indicated that both the vacuoles and cell walls might be evolved the Cd tolerance mechanisms to protect metabolically active cellular compartments from toxic Cd concentrations. Meanwhile, Cd taken up by the plant existed in different chemical forms. Results showed that the majority of Cd in plant was in undissolved Cd-phosphate complexes (extracted by 2 % CH 3 COOH), followed by water-soluble Cd-organic acid complexes, Cd(H 2 PO 4 ) 2 , pectates and protein form (extracted by deionized water and 1 M NaCl), whereas only small amount of Cd in roots was in inorganic form (extracted by 80 % ethanol), which suggests low capacity to be transported to aboveground tissues. It could be suggested that Cd integrated with undissolved Cd-phosphate complexes in cell wall or compartmentalization in vacuole might be responsible for the adaptation of the mining ecotypes of A. wardii to Cd stress.

Research ArticlePb Uptake and Phytostabilization Potential of the Mining Ecotype of Athyrium wardii (Hook.) Grown in Pb-Contaminated Soil Phytostabilization has been proposed as a cost-effective remediation strategy to immobilize metals in heavy metal polluted soils. A pot experiment was conducted to evaluate the Pb uptake characteristics and phytostabilization potential of the mining ecotype (ME) of Athyrium wardii and the corresponding non-mining ecotype (NME) when exposed to the Pb contaminated soils for 40 days. The ME was more tolerant to Pb than the NME when grown in Pb contaminated soil, and the ME demonstrated a greater Pb accumulation ability in roots (30.6-175.45 mg plant À1 ) than the NME (0.85-25.59 mg plant À1 ). The bioaccumulation coefficients of ME ranging from 52.02 to 83.16 were 3.24-8.89 times higher than those of the NME under Pb treatment, and the translocation factors of ME ranging from 0.022 to 0.079 were <1. The ME showed a higher capability in absorbing available Pb in soil than the NME. Furthermore, Pb remediation factors in roots of the ME were 6.93-15.35 times higher than those of the NME, and the plant effective number in roots of the ME ranging from 5.70 to 12.74 were lower than those of the NME. These results indicated that the ME showed a greater Pb uptake and phytostabilization potential than the NME, which enabled it as a worthy candidate for Pb phytostabilization.
