Abstract
Plants were known to be able to accumulate heavy metals from the environment. The uptakes of heavy metals by two aquatic plants in their natural habitats were investigated for their potential in removing heavy metals from aqueous environment. These macrophytes were chosen as they can easily be obtained and are well spread in our environment. They can be found in ditches rice fields and in wetlands of Kota Kinabalu. The overall concentration and distribution of Cd Cu Pb and Zn in Eichornia crassipes and Monochoria hastata were determined. The highest concentration was Pb 205 ug/g and Zn 170 ug/g in Monochoria hastata and Eichornia crassipes respectively. Pb was found to be higher in leaves 84.3 ug/g compared to the roots 69 ug/g and stalks 51.7 ug/g of Monochoria hastata. Zn was found to be high by 3-fold in roots 111.3 ug/g compared to the leaves 32.2 ug/g and stalks 26.5 ug/g of Eichornia crassipes. Heavy metals accumulated by these aquatic plants were probably influenced by the site where they were taken. This preliminary study showed that these two aquatic plants may have potential for heavy metals removal in wastewater treatment.
