A Study on Arsenic and the Heavy Metals in the Mulde River System

A long-term survey of heavy metals and specific organic compounds in biofilms, sediments, and surface water in a heavily affected river in the Czech Republic

“…The Mulde River is polluted by specific organic compounds coming from chemical industry in the Bitterfeld area (Wilken et al 1994;Franke et al 2005). Together with other rivers in the Harz region, which are characterized by high contents of salts (Ca, Mg, Na, and Cl) due to their different geological background, the Mulde River is polluted by heavy metals produced by the mining industry and industrial and urban activities (Kowalik et al 2003;Klemm et al 2005;Hintelmann and Wilken 1995).…”

“…2 a Concentrations of heavy metals and specific organic compounds in surface water-comparison of the 1994-1996 period (data from Havlík et al 1997a, b) and the current survey (2004)(2005)(2006)(2007). b Concentrations of heavy metals and specific organic compounds in surface water-comparison of the 1994-1996 period (data from Havlík et al 1997a, b) and the current survey (2004)(2005)(2006)(2007) decreasing trends in water pollution have been described for the Elbe River and other similarly anthropogenically affected rivers in post-communist countries (Adams et al 2001;Klemm et al 2005), and decreasing loads of organic wastes and mercury were already demonstrated soon after 1990 (Simon 1991).…”

Distribution and speciation of arsenic around roots in a contaminated riparian floodplain soil: Micro-XRF element mapping and EXAFS spectroscopy

“…It is subject to occasional flooding (Brandt, 2003;Klemm et al, 2005). The contamination at the site mainly results from past mining activities 150 km upstream in the Ore Mountains (Erzgebirge), where sulfide ores have been mined for centuries for Ag, Pb, and Zn.…”

Consequences and opportunities from river breach and decant of an acidic mine pit lake

“…Fresher and moderately alkaline lake surface water (essentially CRSB water) from riverine flow-through is more likely to enable the lake to meet regulatory requirements for recreational use. Further, there is potential for the water quality of CRSB water, particularly for AMD removal of excess nutrients such as P (Kleeberg and Grüneberg, 2005), to be enhanced by passage through the pit lake as has been observed with metals removal in pit lake flow-through situations (Klemm et al, 2005).…”
