Abstract

A lack of aquatic plants in aquatic ecosystem may suggest a reduced population of wildlife whereas the absence of aquatic plants may indicate problems in water quality. However an overabundance of aquatic plants may due to excessive nutrients, organic or heavy metals interference. Aquatic plants are well known as a good accumulator for heavy metals in phyto-technologies approach as a green friendly since the last decades. Therefore this study aimed to assess heavy metals remediation rate of Lemna minor and Salvinia natans at three different concentrations ranging from low, medium and high (1 mglˉ¹, 2 mglˉ¹ and 5 mglˉ¹) of three types of heavy metal (Cu, Fe and Zn) at four different period of time (week 1 until week 4) through in vivo model system. The results established that there were significant differences between the sequestration rate of both species. S. natans ability and resistance over 3 types of heavy metal toxicity were much more higher and stable compared to L. minor and the capability of both species were varied and depending on the plant tolerance or resistance mechanism itself. Thus, high relationship between metal removal in water and aquatic plant species indicates that those plants can effectively use for the removal of heavy metals from polluted or contaminated aquatic ecosystem of different concentrations.
