over the years, there has been an obvious pollution problem in lagos area, nigeria with high population of over eleven million and the near absence of waste management infrastructures. concentrations of some pollution parameters and trace elements (temperature, ph, salinity, so42-, no3-, po43-, f-, do, bod, cod and coliform, cr, co, ni, ag, cd and pb) were determined from water bodies of isolo ...

Nacharam and its surroundings, located inside the city of Hyderabad in Telangana State, India, is vulnerable to water-borne diseases; therefore, the present research works on concentrations of dissolved hexavalent chromium (57－263 mgL-1), lead (34－65 mgL-1), cadmium (2.3－22.4 mgL-1), and nickel (from below detection limit to 6.5 mgL-1) in different surface water and groundwater bodies of this a...

Water bodies are ubiquitous features in Arctic wetlands. Ponds, i.e., waters with a surface area smaller than 10 m, have been recognized as hotspots of biological activity and greenhouse gas emissions but are not well inventoried. This study aimed to identify common characteristics of three Arctic wetlands including water body size and abundance for different spatial resolutions, and the potent...

Monitoring open water bodies accurately is an important and basic application in remote sensing. Various water body mapping approaches have been developed to extract water bodies from multispectral images. The method based on the spectral water index, especially the Modified Normalized Difference Water Index (MDNWI) calculated from the green and Shortwave-Infrared (SWIR) bands, is one of the mo...

Over the last several decades, warming in the Arctic has outpaced the already impressive increases in global mean temperatures. The impact of these increases in temperature has been observed in a multitude of ecological changes in North American tundra including changes in vegetative cover, depth of active layer, and surface water extent. The low topographic relief and continuous permafrost cre...

The state of knowledge of grass carp ( Ctenopharyngodon idella Val.) effects on water bodies are summarized based on a review of selected literature and my own experience from South Bohemian ponds. The subjects considered include aquatic plant control using grass carp, fish age and stocking densities, and direct and indirect consequences of its introduction to water bodies including impacts on ...
