Abstract

The increased use of incineration with modern emission control devices for reducing the mass of municipal solid waste is resulting in ever greater quantities of ash to be disposed. Heavy metals present in the original refuse are concentrated in the ash and landfill disposal of it has prompted public concern of possible contamination of groundwater through leaching. Several investigators have reported the presence of heavy metals such as lead and cadmium in aqueous leachates of refuse incinerator ashes in laboratory studies. It was of interest to determine the effect of such leachates on fish. In the work reporter here, goldfish were exposed to aqueous leachates of municipal refuse incinerator ash. Visual observations of fish behavior, heavy metal analysis and histologic examination of tissues were then carried out.
