Abstract

Phytoremediation is defined as cleaning up of pollutants mediated primarily by plants. It is an emerging technology for environmental remediation that offers a low-cost technique suitable for use against different types of contaminants in a variety of media. Phytoremediation is potentially applicable to a diversity of substances, involving hyperaccumulators heavy metals and radionuclides. It is also applicable to other inorganic contaminants such as arsenic, various salts and nutrients, and a variety of organic contaminants, including explosives, petroleum hydrocarbons and pesticides. At least there are one taxon of plant as hyperaccumulator for Cd, 28 taxa for Co, 37 taxa for Cu, 9 taxa for Mg, 317 taxa for Ni, and 11 taxa for Zn. Extensive progress were done in characterizing physiology of plants which hyperaccumulate or hypertolerate metals. Hypertolerance is fundamental to hyperaccumulator, and high rates of uptake and translocation are observed in hyperaccumulator plants. Hyperaccumulator plants and agronomic technology were undertaken to improve the annual rate of phytoextraction and to allow recycling of soil toxic metals accumulated in plant biomass. These techniques are very likely to support commercial environmental remediation. Most phytoremediation systems are still in development, or in the stage of plant breeding to improve the cultivars for field use. However, application for commercial purposes has already been initiated. Many opportunities have also been identified for research and development to improve the efficiency of phytoremediation.

Abstract

Water contamination with heavy metals, mainly mercury and cyanide (CN) due to small scale of public mines and large scale of industrial mines have been in concern to residents around the area. Surveys of heavy metal contamination in aquatic environments, such as rivers and paddy fields over two gold mine areas in West Jawa were conducted and possible solution of using indigenous plants for phytoremediation was studied. The results showed that most of the rivers and other aquatic environments were affected by gold mine activities. Rivers, ponds, and paddy fields around illegal public mines were mostly contaminated by mercury in considerably high levels, such as paddy fields in two locations (Nunggul and Leuwijamang, Pongkor) were contaminated up to 22.68 and 7.73 ppm of Hg, respectively. Whereas rivers located around large scale industrial mines were contaminated by CN. Possible solution of cleaning up by using green technology of phytoremediation was examined. Some plant species grew in the contaminated sites showed high tolerance and potentially effective in accumulating cyanide or mercury in their roots and above ground portions. Lindernia crustacea (L.) F.M., Digitaria radicosa (Presl) Miq, Paspalum conjugatum, Cyperus kyllingia accumulated 89.13, 50.93, 1.78, and 0.77 ppm of Hg, respectively. Whereas, Paspalum conjugatum, Cyperus kyllingia accumulated 16.52 and 33. 16 ppm of CN respectively. Key words: phytoextraction, contaminants, cyanide, mercury
