The toxicity of leachates from landfill sites in the remediated lands at Sydney Olympic Park, Homebush Bay, was evaluated in four tests, encompassing three biological levels. These included: the submitochondrial particle (SMP) test, Microtox, and the sea urchin fertilisation and larval development tests. The aims were to determine the level of leachate toxicity and make recommendations on tests...

Heavy metals (HMs) are common components of landfill leachates and piggery wastewater, which correspond with possible applications of the anaerobic ammonium oxidation (anammox). For this reason, the study of the fate and effect of HMs on the anammox process is of utmost importance. In this work, the effect of several HMs on the specific anammox activity (SAA) was studied. For this purpose, the ...

The Danish counties have performed numerous investigations of old landfills. These investigations have been presented in several reports, but no comprehensive summary of the findings has been carried out. The objective of this study was to evaluate the typical composition of leachates from old smaller landfills by a comprehensive review of the investigations carried out by the counties. In tota...

In most countries, sanitary landfilling is nowadays the most common way to eliminate municipal solid wastes (MSW). In spite of many advantages, generation of heavily polluted leachates, presenting significant variations in both volumetric flow and chemical composition, constitutes a major drawback. Year after year, the recognition of landfill leachate impact on environment has forced authoritie...

In many parts of the world, impact open landfills on soils, biosphere, and groundwater has become a major concern. These frequently generate pollution plumes, contours which can be delineated by non-intrusive geophysical measurements, but in arid environments, high soils resistivity is usually an obstacle, results low number studies that have been carried out there. addition, such prospecting u...

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...

Landfill leachate is regarded as a significant point source of pollutants that may pose hazard to the environment, particularly surface and ground waters. Leachates are highly variable heterogeneous. Our study was focused on characterization landfill leachates derived from young (YDS) matured (MDS) dumpsites in terms abundance micropollutants, antimicrobial resistance genes (ARG), microbial com...
