Preliminary Analyses of Urban Wastes, New York Metropolitan Region.
Abstract
Preliminary analyses were made of 17 sewage sludge samples from sewage treatment plants serving 11.9 million persons in the New York Metropolitan Region. The sludges consist of about 55 per cent organic matter, which, in turn, accounts for about 55 per cent of the total oxygen demand of the sludges. About 45 per cent of the sludge consists of aluminosilicate material, chemically similar to shale. The samples are enriched, compared to sedimentary rocks and soils, in the following elements; silver (150x), chromium (10x), copper (50x), tin (30x), and zinc (30x). All of these elements are common industrial materials. These preliminary analyses indicate the simi-quantitative spectrochemical analyses may be useful for determining order-of-magnitude concentrations of at least 24 elements commonly occuring in sewage sludges.
