While new contaminants have emerged, traditional contaminants including heavy metals continue to threaten the lake's resources. In this study, the levels and distribution of heavy metals in Laguna de Bay were investigated. Surface water samples from nine sampling sites were analyzed for As, Pb, Cd...
heavy metals are the most toxic and persistent contaminants that are ubiquitously disseminated in the freshwater resources throughout the country. Fresh water lakes and rivers are the most vulnerable to contamination with metal pollutants such as arsenic, lead, cadmium, chromium and nickel, emanating ...

The concentrations of heavy metals in surface water show substantial seasonal differences in summer and winter in the Inegol Plain. Cr, Fe, Pb and Zn concentrations were recorded within the permissible limits throughout the plain. However, according to the background value of Cu, Mn and Ni, ...
The concentration of heavy metals in the gold deposit areas depends upon the distance from the pollution source and scalar transport in rivulet flows, decreases along the flow direction. The concentration and distribution of heavy metal pollutants in surface water are dominated by the geochemical ...
A field study of the mobilities of heavy metals was done in the Tri-State Mining District near Joplin, Missouri. The processing of ores left many large tailings piles in this region which are predominantly chert, but contain minor amounts of carbonate and sulfide minerals. The residual sphalerit...
Surface water pollution with heavy metals in the lower catchment of Jiu river basin, according to the Water Framework Directive (2000/60/EC). The Water Framework Directive establishes a single transparent, effective and coherent water policy by defining a strategy to combat pollution by requiring ...
Trace pollutants in the surface water of the Arctic region have been analyzed by the capillary gas chro-matography with the micro-electron capture detector (GC- mECD), the gas chromatography-mass spectrometry (GC- MS) and the inductively coupled plasmas-mass spectrometry (ICP-MS). Compared with...
(US Water Quality Criteria,USEPA1999).Cd was the most polluted heavy metals in suspended solids and surface sediments of the Yangtze-Taihu water diversion section,and the concentration of Cd in suspended solids and surface sediments were 2.20,1.78μg/g respectively,which were 16 times and 13 ...
