Heavy metal uptake by plankton and other seston particles

Separation of micro-phytoplankton from inorganic particulate in Antarctic seawater (Ross Sea) for the determination of Cd, Pb and Cu: optimization of the analytical methodology

“…Normally in the literature, data about trace elements in particulate components of the marine environment refer to the total concentration in this phase. [18][19][20][21] In the use of lters for the separation of the particulate phase, we must pay attention to the possible contamination resulting from lters. In the case of the determination of trace elements, lters have to be washed carefully for a long time with ultrapure acids to reduce heavy metal content and to have good blank lters.…”

“…Regarding this last point, to perform a voltammetric determination of Cd, Pb and Cu in the phytoplankton cells, organic compounds must be destroyed because they could interfere with the analysis. 18 The microwave digestion of organic samples is a feasible procedure that has been applied to different matrices. [27][28][29] Therefore, we decided to optimize this kind of digestion for phytoplankton samples.…”

Trophic Transfer of Cd, Cu, Pb, Zn, P and Se in Dutch Storage Water Reservoirs

“…This can be related to the metal uptake via roots and leaves (macrophytes), and adsorption (phytoplankton) (e.g. Revis et al 1989 ; Guilizonni 1991 ). Nevertheless, we found a difference between the rooted E. nuttallii and Potamogeton species.…”

“…Luoma 1983 ). Phytoplankton and macrophytes have a high capability to become enriched with heavy metals via absorption or adsorption routes (Revis et al 1989 ; Chojnacka et al 2005 ; Monteiro et al 2011 ), and uptake of metals via roots and leaves, respectively (Guilizzoni 1991 ). Within fish species the elemental content depends on factors such as location, age, size, life history, habitat, feeding guild and exposure route (Andres et al 2000 ; Farkas et al 2003 ; Vijver et al 2004 ; Merciai et al 2014 ; Van Ael et al 2017 ; Ahmed et al 2019 ).…”

Cadmium and lead in fishes and in selected elements of the Świdwie Lake ecosystem

“…The total content of metal in water can be divided into two fractions: metal bounded in suspended matter and the dissolved fraction (Glazewski 1992). The proportion of these two fractions of heavy metals in natural waters depends on many physical and chemical factors, such as salinity, complexing components of the dissolved organic matter, forms of metal occurrence, composition and effective surface of the suspended matter molecules (Revis et al 1989). Even small amounts of heavy metals present in waters are very quickly accumulated in the bottom sediments (Strzebonska 1997) and the level of their presence in lake sediments can be a pollution indicator (Kwapulinski et al 1991;Warda and Bubicz 1992;Gonet and Cieslewicz 1997).…”
