Survey results describing the levels and prevalences of zoonotic agents in 1,549 livestock waste samples were analyzed for significance with livestock husbandry and farm waste management practices. Statistical analyses of survey data showed that livestock groups containing calves of <3 months of age, piglets, or lambs had higher prevalences and levels of Campylobacter spp. and Escherichia coli ...

Water pollution due to organic contaminants is a serious issue because of acute toxicities and carcinogenic nature of the pollutants. Among various water treatment methods, adsorption is supposed as the best one due to its inexpensiveness, universal nature and ease of operation. Many waste materials used include fruit wastes, coconut shell, scrap tyres, bark and other tannin-rich materials, saw...

Plutonium-contaminated solid wastes including combustible, incombustible and chlorine contained waste have been generated during Mixed Oxide,(MOX) fuel fabrication by Japan Atomic Energy Agency (JAEA). Incinerations of chlorinated wastes cause the problems related to corrosion of the equipments and dust loading in the vent exhaust system. The JAEA has designed and manufactured a new type incine...

More than 167,000 m of mixed waste, waste that contains both chemically hazardous and radioactive components, are in the known inventory at DOE sites that formarly produced nuclear defense materials. The inventory contains both mixed low level wastes (MLLW) and mixed transuranic wastes (MTRU). Site cleanup and decommissioning activities during the coming years are expected to nearly double this...

Although industrial and commercial uses of mercury have been curtailed in recent times, there is a demonstrated need for the development of reliable hazardous waste management techniques because of historic operations that have led to significant contamination and ongoing hazardous waste generation. This study was performed to evaluate whether the U.S. EPA could propose treatment and disposal a...

dental offices produce a variety of dangerous wastes during normal business day. most of these waste are non-hazardous that can be managed as household wastes; however, some component are hazardous and can pose a risk to human and the environment if discarded to municipal solid wastes. these types of wastes must be managed separately. therefore, the aim of this study was to assess the component...
