PCDD/DF in leachates from Korean MSW landfills.
We analyzed levels of PCDD/DF in leachate liquid and solid from five Korean municipal solid waste landfills to investigate the relationship between PCDD/DF and dissolved organic carbon and suspended solids in raw leachate. The concentrations of PCDD/DF ranged from 173.2 to 1329.4 pg/l and 4.1 to 46.22 pg-TEQ/l. The range of PCDD/DF was 123.2-1161.3 pg/l in leachate solid and 50.0-383.3 pg/l in ...
متن کاملApplicability of leachates originating from solid-waste landfills for irrigation in landfill restoration projects.
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...
متن کاملToxicity identification evaluation of leachates from municipal solid waste landfills: a multispecies approach.
The toxicity of leachates from two municipal solid waste (MSW) landfills in Southern Italy was characterized using a toxicity identification evaluation procedure. The chemical and physical fractionation techniques were: pH adjustment, pH adjustment/filtration, pH adjustment/C(18) solid phase extraction, graduated pH and EDTA chelation. All the samples exhibited acute toxicity towards the bacter...
متن کاملAssessment of Heavy Metals and Organics in Municipal Solid Waste Leachates from Landfills with Different Ages in Jordan
A comprehensive assessment of heavy metals and organic content was performed for leachates produced from a number of old and new landfills in Jordan over 9 month in efforts to set a framework for treatment regulations. All leachates were basic (pH = 7 9) and have high electric conductivity and high organic contents (COD = 3000 500,000 mg/L, TOC= 500 21,000 mg/L). The organic content was inverse...
متن کاملCombined anaerobic-aerobic treatment of landfill leachates
As a first step of treatment of landfill leachates (total COD – 1,430-3,810 mg/l, total nitrogen 90162 mg/l), a performance of laboratory UASB reactors has been investigated under mesophilic (30 C), sub-mesophilic (20 C) and psychrophilic (10 C) conditions. Under hydraulic retention times (HRT) of around 7 h, when the average organic loading rates (OLR) were around 5 g COD/l/day, the total COD ...
