Adsorbable organic halides (AOX) and AOX formation potential (AOXFP) were investigated in 46 landfill lea-chates as potentially toxic parameters. AOX in landfill leachate was within the range <10–2200 mg Cl/l, and AOXFP was within 51–15 000 mg Cl/l. AOX and AOXFP correlated with chemical oxygen demand (COD).AOX discharge from closed landfills was generally lower than that from operating landfil...

This study investigated the immunotoxic potentials of raw and simulated leachates from Olushosun municipal solid waste landfill in rat using quantitative leucocyte and differential counts. Blood samples of rats intraperitoneally exposed to 1 – 25 % concentrations of each of the leachate samples for 48 hours were examined post treatment for leukocyte and differential counts. Compared to the nega...

A considerable amount of research has been conducted to demonstrate the development of bioreactor landfills promoted by leachate recirculation [1-10]. The effectiveness of leachate recirculation has been well documented in lysimeter studies [1, 5, 11, 12], test cell studies [2, 13, 14-16] and full-scale studies [17-20]. However, the results from these investigations might not be applied appropr...

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...

−Landfill leachate is a toxic effluent of a decomposing landfill that is produced when rainwater percolates through the landfill leaching out contaminants and pollutants. Untreated leachate is a potential source for the contamination of soil, surface and ground water. In this study, the treatment processes such as granular activated carbon (GAC) adsorption/bio-sorption (batch), and advanced oxi...

Household waste is directly related to people's quality of life and urban environment. As people pursue higher spiritual quality, pay more attention the treatment domestic garbage leachate. At present, although China has made some achievements in leachate, there are still many problems, which need be solved. In this paper, leachate will elaborated.

Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical ...

The generation of contaminated leachate remains an inevitable consequence of the practice of solid waste disposal in landfills. The collection and treatment of leachate have become common practice in order to prevent environmental pollution. Leachate treatment is highly dependent on the quality of leachate, which in turn is influenced by various factors including waste composition and operation...

Since, landfill areas are still the most widely used solid waste disposal method across the world, leachate generated from landfills should be given importance. Leachate of landfills exerts environmental risks mostly on surface and groundwater with its high pollutant content, which may cause unbearable water quality. This leads to the obligation for decontamination and remediation program to be...
