Landfills constitute the largest treatment and disposal reservoirs of anthropogenic waste on earth they are continuously releasing antibiotic resistance genes (ARGs) to environment for decades via leachates. Little is known about association between ARGs human bacterial pathogens as a function time. Here, we quantified 10 subtypes ARGs, integrons, (HBPs). Except encoding sulfonamides, beta-lact...

abstract background: leachate produced by waste disposal sites can be contaminating groundwater. the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwater contamination. the main objective of the study is to evaluate aquifer pollution vulnerability in the new waste disposal sit...

Abstract Storage of wastes leads to severe problems water pollution and neighboring matrices due the infiltration landfill leachate. Uncontrolled waste storage can lead groundwater pollution, which serious health for living. Engineered barriers be a solution these problems. The purpose this study was develop novel composite materials – clay-based, activated carbon, cement, PVA polymer. These co...

Landfill leachates are a mixture of high concentration organic and inorganic contaminants need to be appropriately treated due their toxicity severe adverse effects on the environment. Here, we studied treatment landfill leachate through heterogeneous Fenton-like oxidation process using zirconia supported copper catalyst (Cu/ZrO2). Reaction conditions such as pH, amount catalyst, oxidant dose, ...

Abstract To add value to wastes from the coffee crop, this research physically and chemically characterized pulp waste an organic farm crop located in Santa Bárbara (Antioquia-Colombia), specifically analyzing whether or not material has promise for heavy metal removal wastewater, such as landfill leachate. The was thermally modified improve its physical chemical condition sorption capacities. ...

Landfill monitoring is necessary to avoid adverse environmental impacts. Toxicity tests are now incorporated into landfill hazard assessment. Toxicity of leachate in a lagoon draining the AbaEku landfill, Ibadan, Nigeria was investigated using bioassays. 96hr bioassays were carried out using arthropods (Insecta larvae of Chironomus sp.; Culex pipiens); amphibians (tadpoles of Bufo regularis); a...

The objective of this study was to identify the organic compounds removed from the leachates when treated with coagulation-flocculation and Fenton-Adsorption by gas chromatography coupled to mass spectrometry (GC-MS) in order to identify toxic compounds that could be harmful for the environment or human health. Physico-chemical characterization of the raw leachates (RL) was carried out before a...
