13 Oil wastes produced in large amounts in the processes of oil extraction, refining, and 14 transportation are of great environmental concern because of their mutagenicity, toxicity, high 15 fire hazardousness, and hydrophobicity. About 40% of these wastes contain radionuclides; 16 however, the effects of oil products and radionuclides on soil microorganisms are frequently 17 studied separatel...

The methodology for evaluating the impacts and damage costs ('external costs') due to pollution from waste treatment is described and the results are presented, based on the ExternE project series of the European Commission. The damage costs of landfill and incineration of municipal solid waste are compared, with due account for energy and materials recovery, as well as possible differences in ...

A feeding trial was conducted to investigate the effect of dietary supplementation of Bacillus subtilis LS 1-2 grown on citrus-juice waste and corn-soybean substrate on growth performance, nutrient retention, caecal microbial population and intestinal morphology in broilers. Three hundred twenty d-old Ross chicks were randomly allotted to 4 treatments on the basis of BW in a randomized complete...

5 A considerable amount of solid wastes is generated every year from construction and demolition (C&D) 6 activities in Hong Kong. The C&D waste can be classified into inert and non-inert wastes, in which the 7 inert waste is normally disposed of in public fills as reclamation materials, and the non-inert part is dumped 8 at landfills. Under the current waste generation trend, all landfills and ...

The main objective of this paper is to provoke and stimulate debate on the health effects of long-term, low-level exposure of human populations to toxic metals. Over one billion (10(9)) human guinea pigs are now being exposed to elevated levels of toxic metals and metalloids in the environment. The number of persons suffering from subclinical metal poisoning is believed to be several million. A...

Ceramic coated carbon steel coupons were corrosion tested in water with dissolved salts to simulate exposure to evaporation concentrated groundwater in an underground nuclear repository. Metallography revealed no corrosion at the ceramic metal interface of dense coatings, even though electrical measurements demonstrated that the coatings were slightly porous. Experimental results and a model to...

Abstract The aluminum recovery from white dross by a mechanical treatment and sizing followed remelting process was investigated. subjected to ball mill, the obtained particles were sized in different ranges. They studied advanced materials characterization techniques. It found that larger contain high metallic portions, most non-metallic components of are fine fraction < 1 mm. Al-rich (>...

Abstract Waste pharmaceutical blister packages (WPBs) are a source of solid waste, which composed plastics and aluminum, therefore acting as potential for secondary aluminum. The structure WPBs makes the recycling aluminum notably more complex than typical recycling. Currently, WBPs disposed municipal waste; thus, is lost from circulation during incineration. In this work, three types were stud...

the province of bushehr is located in southern area of iran and north of persian gulf. solid waste management in bushehr’s villages was the aim of this research. for the sake of this study, 21 villages scattered all over the province were selected. field studies showed that about 646 grams of residential solid waste per capita is generated in selected villages every day. there are 322 shops i...
