“…(1), where [M] refers to the concentration of the heavy metal of interest while [Y] is the concentration of the normalizing element (Li). These two concentrations were obtained both for the sample and the set of reference background where the average shale values of each heavy metal and the normalizing element from literatures were used as the background reference concentration (Ho et al, 2012;Silva-Filho et al, 2014;Turekian and Wedepohl, 1961)…”

In the present study, the concentrations of trace and alkali metals in leaves of four common helophytes, Sparganium erectum, Glyceria maxima, Phalaris arundinacea, and Phragmites australis, as well as in corresponding water and bottom sediments were investigated to ascertain plant bioaccumulation ability. Results showed that Mn and Fe were the most abundant trace metals in all plant species, while Co and Pb contents were the lowest. Leaves of species studied differed significantly in respect of element concentrations. The highest concentrations of Mg, Na, Fe, Mn, Cu, Pb, and Ni were noted in S. erectum while the highest contents of Co, Ca, Zn, and Cr in Phalaris arundinacea. Phragmites australis contained the lowest amounts of most elements. Concentrations of Co, Cr, Fe, and Mn in all species studied and Ni in all except for Phragmites australis were higher than natural for hydrophytes. The leaves/sediment ratio was more than unity for all alkali metals as well as for Cu and Mn in Phragmites australis; Cr, Co, and Zn in Phalaris arundinacea; Cr and Mn in S. erectum; and Cr in G. maxima. High enrichment factors and high levels of toxic metals in the species studied indicated a special ability of these plants to absorb and store certain non-essential metals and, consequently, their potential for phytoremediation of contaminated aquatic ecosystems.

“…Expansion of cities and attendant urban runoff and sewage releases cause local pollution (Couceiro, Hamada, Forsberg, Ferreira, & Silva, 2007; Melo et al, 2019; Thomas et al, 2014). Leaching from landfill and fish farms can cause trace elements contamination (Capparelli et al, 2020; Silva‐Filho et al, 2014), and plastic waste has been found in aquatic organisms (Andrade et al, 2019). Over‐harvesting of water for human consumption may be a concern in the future in urban environments as basic sanitation is precarious in the region according to ABES (2019).…”

Limnological aspects of Amazon floodplain lakes are examined in the context of aquatic conservation. A prerequisite to detecting and evaluating changes that could threaten the ecological health and organisms in floodplain lakes is understanding variation under present conditions. Based on one of the few studies with regular measurements over 2 years, chlorophyll, total phosphorus, dissolved oxygen, transparency, and total suspended solids in Lake Janauacá indicate that the lake is naturally quite variable with a mesotrophic to eutrophic status. Direct threats to ecological health of floodplain lakes include mining operations that can increase turbidity and trace metals and reduce nutritional quality of sediments. Mercury contamination and methylation leads to bioaccumulation in aquatic organisms. Deforestation in uplands increases nitrogen and phosphorus inputs to floodplain lakes and can alter trophic status. Deforestation in floodable forests alters the habitat and food of the fish that inhabit these forests. Cumulative limnological responses as catchments are altered by urban, agricultural, and industrial developments, and as inundation is altered by changes in climate and construction of dams, have major implications for the ecology of floodplain lakes. To improve understanding and management of threats to the conservation of aquatic Amazon biota and ecosystems requires considerably expanded and coordinated research and community‐based management that includes the spectrum of floodplain lakes throughout the basin.
