Landfills are the largest sources of methane (CH4) emissions to the atmosphere in the United States. However, few measurements of whole landfill CH4 emissions have been reported. Here, we present the results of a multi-year study of whole landfill CH4 emissions using atmospheric tracer methods at the Nashua, New Hampshire Municipal landfill in the northeastern United States. Emissions were meas...

Field and laboratory studies were conducted to estimate concentration of potential contaminants from landfill in the underlying groundwater, leachate, and surface water. Samples collected in the vicinity of the landfill were analyzed for physiochemical parameters, organic contaminants, and toxic heavy metals. Water quality results obtained were compared from published data and reports. The resu...

Concern that living near a particular landfill site in Wales caused increased risk of births with congenital malformations led us to examine whether residents living close to 24 landfill sites in Wales experienced increased rates of congenital anomalies after the landfills opened compared with before they opened. We carried out a small-area study in which expected rates of congenital anomalies ...

Landfill site is a significant and risky part at the same time in city. In planning an urban city, pollution caused by landfill damages surrounded areas, especially residential zones, if it does not follow sanitary rules. The from landfills threat environment and, consequently, human health wellbeing, so essential to maintain safe healthy selecting site. From this point of view, research aims c...

Generally, the bridges or buildings cannot be constructed on a refuse landfill, since the special chemical compositions and microorganisms in landfill will impose adverse effects on the concrete foundations. Especially, the impacts on their durability are still unknown. The purpose of this paper is to get the corrosive features of a refuse landfill to give suggestions for the durability design ...

Assessing odour annoyance generated by landfill areas involves a number of difficulties due to the fugitive, diffuse and multiple characters of odour sources. Analyses of ambient air by GC-MS, spot FID measurements or the determination of the odour concentration by dynamic olfactometry on the basis of samples collected through flux chambers, while providing valuable results, do not allow to enc...

There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a separ...
