Abstract Nitrification–denitrification is an environmentally friendly and cost-effective way to treat landfill leachates. Special attention has been given the nitrification step, usually limiting one due its special sensitivity environmental factors. Here, effect of acclimatization nitrifying biomass two different intermediate leachates with salt concentrations, COD BOD 5 studied. Despite compl...

landfill leachates and leachate sediments were investigated in order to survey the discharge of uranium (u) from municipal solid waste (msw) landfills and municipal solid waste incinerator (mswi) bottom ash landfills. concentrations of u in the leachates were as high as or higher than concentrations of cd, a metal more often discussed when considering the environmental effects of landfill leach...

Municipal landfills receive a high amount of plastic waste and due to the occurring physical biochemical degradation processes, could be significant sources microplastics (MP). Evaluating threat groundwater through transfer MP via landfill leachates require more research. The former “Prairie de Mauves” landfill, operated from 1963 1987 by municipality Nantes (France), located above alluvial Loi...

Introduction: Secondary carbonate minerals produced by low temperature aqueous processes [1] in the martian meteorite ALH 84001 are evidence of an early active hydrosphere on Mars when they were formed ~3.9 Ga ago [2]. Further evidence for an early hydrosphere includes orbital and surface observations of diverse alteration mineral assemblages [e.g. 3-5] and fluvial geomorphology [6]. While carb...

Young landfill leachates (LFL) collected from Djebel Chekir (Tunisia) discharge area were found to be highly loaded with organic matter, ammonia, salts, heavy metals, phenols and hydrocarbons. Despite the possibility of their biodegradability, they represent a threat to the environment and show some resistance to conventional wastewater treatment processes. For these reasons, this study attempt...

Abstract Borehole water has been the main source of drinking for communities living within Nnewi metropolis. The quality this borehole significantly affected by presence unlined waste dumpsites which release leachates. present study investigated physicochemical characteristics and located around environment dumpsite in Nnewi. In study, thirty-two (32) samples were collected from (16) control ar...
