Metals in chosen aquatic plants in a lowland dam reservoir

Abstract

The research involved S³up Dam Reservoir, which is used as a source of drinking water and for flood prevention. The research material was made up of aquatic plants and water collected in the littoral zone of the reservoir, in which copper, nickel, cadmium, lead and zinc contents were determined.Ceratophyllum demersum L. turned out to be the best accumulator of nickel, cadmium and zinc, Potamogeton crispus L. -copper, and Phragmites communis Trin -zinc. The presence of plants in the backwater area of the dam reservoir definitely improves water quality, not only thanks to their metal accumulation properties but because of their ability to act as a filter of substances carried in the water.

Bioaccumulation of Heavy Metals in Hydromacrophytes from Five Coastal Lakes (North-Western Poland, Baltic Sea)

“…1999. Approximately the same values were found for above-the-surface plants from a dam storage reservoir providing water to an urban agglomeration with an agricultural catchment area in Poland (Senze et al 2009). A more or less the same Cd content was found in submergent plants from a lake in Malaysia used for recreational purposes (angling, tourism), but located in an industrialised catchment area (mines) (Ebrahimpour and Mushrifah, 2008).…”

“…Approximately the same Ni content was also found in T.latofolia from a lake used for recreation in the south-west of Poland, whose catchment area had a typically agricultural-and-woodland nature (Klink et al 2009). The Ni content in stagnant water reservoirs, whose catchment areas have a medium degree of urbanisation and a strong degree of industrialisation, was similar to that in the coastal lakes (Samecka-Cymerman and Kempers, 2001, Senze et al 2009, Szymanowska et al 1999. In a lake in Syria, with an agricultural and urbanised catchment area subject to anthropogenic activities, the Ni level in emergent plants (P.australis and species from the genus Typha) was higher than that in macrophytes from Poland's coastal lake zone (Hassan et al 2010).…”

“…Consequently, it may be assumed that the load of lake waters with nickel has not changed much over the last several years. A similar BCF characterised the macrophytes from a dam reservoir in the south of Poland, whose catchment area -similarly to that of the coastal lakes -is definitely agricultural (Senze et al 2009). …”

“…Higher concentrations have been found in reservoirs in urbanised ones in waters of the mine reservoirs studied by Mishra et al (2008) had much higher concentrations than those found in the coastal lakes. Lower concentrations have been found in piedmont and mountain waters, both flowing and stagnant, studied by Senze et al (2009). Also, dam reservoirs of stagnant water various types of catchment areas, but not strongly affected by anthropopression, had a lower Cd content than the coastal lakes (Klink et al 2013).…”

“…A similar type of catchment area (agricultural and woodland) and the use for, among other things, recreational, angling and pisciculture, may have a decisive impact on the similarity of concentrations. In studies covering lakes and dam reservoirs in western Poland, characterised by a comparable degree of anthropopression (Senze et al 2009, Szymanowska et al 1999. Furthermore, tests of water from mine reservoirs in Asia lakes in industrial, urbanised regions gave comparable ranges of values (El-Khatib and El-Sawaf, 1998, Hassan et al 2010, Mishra, 2008, Yang et al 2002.…”
