Nanotechnology is an area of intense commercial development, and concerns have been raised about the possible impacts to the environment. Zinc oxide nanoparticles (nanoZnO) are used in transparent sunscreens and may find their way into the environment through wastewater treatment plants and through skin contact with water. The purpose of this study was to examine the bioavailability of Zn in fa...
Co-digestion has drawn much attention because of its potential to increase biogas production among other benefits. Restaurant grease has high energy content and methane production potential and so is a promising substrate for co-digestion with municipal wastewater sludge. Anaerobic co-digestion of municipal wastewater sludge and restaurant grease was investigated at laboratory-scale under mesop...
Municipal Solid Waste (MSW) is complex refuse consisting of various materials with different properties. Some of the components are stable while others degrade as a result of biological and chemical processes. Leachate resulting from this is hazardous pollutant to the soil and ground water underlying. Leaching of this leachate and heavy metals into the soil leads to the contamination of both so...
During the last two decades the multiple functions and values of wetlands have been recognized not only by the scientists and managers working with wetlands, but also by the public. The ability of wetlands to transform and store organic matter has been exploited in constructed wetlands. This paper summarizes the state-of-the-art of the uses of constructed wetlands in water pollution control by ...
The mechanical properties, including strength, deformational behavior, and wetting softening phenomena of municipal solid waste incinerator (MSWI) bottom ash are one of the major concerns for reuse applications. However, owing to the complex constituents of municipal solid waste, the properties of MSWI bottom ash are often highly variable. A series of artificial specimens with controlled chemic...
population growth and consequently increasing waste are made concern about resources degradation. thus, municipal solid waste management (mswm) becomes a priority for experts in recent decades. to apply new technology in mswm and engineering methods is the base of determining strategies, health and environmental policies. mswm is included some factors such as waste generation, collection, trans...

roads, schools, fire stations, hospitals, airports, and much more— all of these different types of infrastructure are financed through municipal capital markets. These markets are vital to american households, both as savers and as consumers of the services these markets enable. objective and informed research on the ways in which municipal markets operate can help inform the decisions of both ...
OBJECTIVES Studies link area features such as neighbourhood socioeconomic deprivation to poor health outcomes. However, there is a paucity of research based on representative data investigating the effects of area-level health services on mortality. This study examines the extent to which municipal health services account for municipal variation in all-cause and cardiovascular disease (CVD) mor...
