Abstract

There is lack of sufficient data that describe which plants can be used in phytoremediation for petroleum and heavy metal contaminated sites, especially in the tropical climate region. The aim of the study was to identify native plants growing on a petroleum contaminated site in Malacca, Malaysia, which have a phytoremediation potential on petroleum. The second aim was to identify native plants at the same contaminated site for phytoremediation of heavy metal contaminants or hyper accumulation plants. In the initial screening of contaminated sites, some of the native plants were found to have the capability to grow in very high concentration of total petroleum hydrocarbon (TPH). This indicates that some of these plants have high potential to act as a phytoremediator. Paspalum vaginatum Sw, Paspalum scrobiculatum L. varbispicatum Hack, Eragrostis atrovirens (Desf.) Trin. exSteud, Cayratia trifolia (L.) Domin, Chloris barbata (L.) Sw, Pycreus polystachyos (Rottb.) Beauv and Ischaemum timorense Kunth were found to be potential phytoremediatory of TPH in contaminated soil. These plants were chosen based on thier high rate of survival in contaminated sites and in terms of uptake or in degrading contaminants. The Biological Accumulation Coefficient (BAC) has been used as a guideline to choose potential plants for heavy metal phytoremediation. In the study, the plants were screened based on BAC values for arsenic (As) and lead (Pb). The selected plants, Melochia corchorifolia L., Ludwigia octovalvis (Jacq.) P. H. Raven, P. vaginatum, Cyperus sphacelatus Rottb., are potential as phytoremediators while L. octovalvis and Melastoma malabathricum L. are potential Pb phytoremediators.

马来西亚石油污染场地植物修复的筛选和鉴定
目前缺乏足够的数据说明哪些植物可用于石油和重金属污染场地的植物修复,特别是在热带气候地区。该研究的目的是鉴定生长在马来西亚马六甲石油污染场地上的具有石油修复潜力的本地植物。第二个目的是在同一污染地点识别原生植物,用于重金属污染物的植物修复或超积累植物。在污染场地的初步筛选中,发现一些本地植物具有在高浓度石油总烃(TPH)环境下生长的能力。这表明其中一些植物具有作为植物修复剂的高潜力。阴道雀稗(paspasum vaginatum Sw),花丛雀稗(paspasum L. varbispicatum Hack, Eragrostis atrovirens, Desf.)指标。exSteud, Cayratia trifolia (L.)Domin,山茱萸(L.)绿足猴(Pycreus polystachyos)对污染土壤中的TPH具有潜在的修复作用。选择这些植物是基于它们在受污染地点的高存活率,以及它们对污染物的吸收或降解能力。生物积累系数(BAC)可作为选择重金属植物修复潜力植物的依据。在研究中,根据植物的BAC值对砷(As)和铅(Pb)进行筛选。所选植物:棉兰(Melochia corchorifolia L.)、八瓣Ludwigia octovalvis (Jacq.)P. H. Raven, P. vaginatum, Cyperus sphacelatus roth。,是潜在的植物修复剂,而L. octovalvis和Melastoma malabatharum L.是潜在的Pb植物修复剂。

期刊介绍: The Journal of Environmental Science and Management (JESAM) is an international scientific journal produced semi-annually by the University of the Philippines Los Baños (UPLB). JESAM gives particular premium to manuscript submissions that employ integrated methods resulting to analyses that provide new insights in environmental science, particularly in the areas of: environmental planning and management; protected areas development, planning, and management; community-based resources management; environmental chemistry and toxicology; environmental restoration; social theory and environment; and environmental security and management.
