In this study, wastes and minerals were incorporated into the production of bricks as a kind of waterpurifying substrate. The brick contained 72% clay, 10% bagasse, 10% steel slag, 5% zeolite, and 3% calcite by weight. The brick exhibited highly and hierarchically porous structure. It can remove phosphate and ammonium simultaneously from aqueous solutions with the maximum adsorption amount of 3.8...
Phosphorus is still recognized as the element driving the matter cycling in freshwater ecosystems. It is the key nutrient in productivity and eutrophication process of lakes and reservoirs. The bottom sediments cumulatively formed inside and in-shore of lakes play a crucial role in accumulation/sorption of phosphorus organic compounds, as well as in release/desorption of the compounds available for...
Authors present the hypothesis that freshwater fish diversity, recruitment and production depend greatly on riparian ecotones. These boundary environments are usually the most diverse elements of aquatic systems. Riparian ecotones moderate the transfer of energy and materials from the land, provide a high load of organic matter including invertebrate food, and moderate competition and predation among...
