Rhizofiltration potential of dominant macrophytes in lentic and lotic ecosystems
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 5
Abstract
The deposition of heavy metals on aquatic ecosystems pose serious threat to humans as these toxic substances may find their way via food chain. The current technologies for heavy metal removal are expensive hence this study was conducted to explore the phytoremediation potential, specifically on rhizofiltration capacity, of plants and the degree of contamination in stagnant and flowing water ecosystems. The study was conducted both in the riparian zones of lentic and lotic freshwater ecosystems of Bukidnon. Lake Pinamaloy represents the lentic while the Pulangui River represents the lotic ecosystems. All vascular plants within the 1x1m2 sampling plots along the one (1) kilometer transect were identified. The most abundant macrophyte species was determined through quantitative analysis. Subsequently, the shoot and root samples of the most dominant species were collected and subjected to analysis for lead accumulation. Macrophyte samples were analyzed via atomic absorption spectrophotometry (AAS). Results show that Fimbristylis littoralis Gaud., the most dominant species in the lentic ecosystem, was able to accumulate lead in the roots at 0.21 mg/kg while Eichhornia crassipes (Mart.) Solms. accumulated an average of 2.70 mg/kg in the lotic ecosystem implying rhizofiltration potentials of these species. This may suggest that these two macrophyte species are bioaccumulators of lead that could reduce lead contamination through rhizofiltration.
