Accumulation and Distribution of Metals in Bolboschoenus maritimus (Cyperaceae), from a South African River

Abstract: The Diep River is a major freshwater ecosystem in the Western Cape, South Africa. Although it is surrounded by many sources of metal pollution, the actual metal levels in this river system are unknown. Wetland plants are known to accumulate metals and may possibly be used as biomonitors of metal contamination in a river system. One such species, the sedge Bolboschoenus maritimus, is found in abundance along the banks of this river. The aim of this study was to investigate and monitor the degree of metal contam… Show more

“…Translocation factors for all trace elements analyzed in P. arundinacea were below unity (Table 3) confirming high root retention capacity for the elements and low intensity of their transfer to other plant organs (Eid et al, 2012). These results were in agreement with several studies according to which trace metal concentrations in belowground organs of different plant species are generally higher than in aboveground tissues (Bonanno, 2011;Shuping et al, 2011). The bioaccumulation of metals in belowground tissues is a strategy that plants use to restrict the distribution of metals to aboveground organs to avoid damage of their photosynthetic tissues (Deng et al, 2004).…”

“…The Diep River, an important freshwater ecosystem (utilised for irrigation and recreation) in the Western Cape province of South Africa, had been reported to be negatively impacted as a result of anthropogenic activities (Jackson et al, 2009;Shuping et al, 2011;Daso et al, 2016). To investigate the source inputs of the 16 US EPA priority PAHs and present the associated probable risk, with the levels at which they were detected in the freshwater system of the Diep River, three sites were selected.…”

“…Studies have shown that the Diep River, an important freshwater ecosystem (utilised for irrigation and recreation) in the Western Cape, South Africa, has been impacted as a result of anthropogenic activities Shuping et al, 2011;Daso et al, 2016). Wastewater effluents from residential and industrial areas have been reported as major point sources of contaminants into the Diep River ).…”
