TLDR
In this article, metal contents of the soils from a field experiment in which two rates of various organic manures, including sewage sludge and sludge compost, were applied from 1942 to 1961.Abstract:
Metal contents are reported of the soils from a field experiment in which two rates of various organic manures, including sewage sludge and sludge compost, were applied from 1942 to 1961. Changes in the concentrations of some elements in the sludges during the 20 years are also presented.The percentage recoveries of the added metals Zn, Cu, Ni, Pb, Cd and Cr in the topsoil varied from 71 to 96%. In 1960, extractability of the metals from the soils by 0·05 M-EDTA was 50% of the aqua regia-soluble total metals. This figure did not vary greatly with metal or with the type of organic manure that was applied.read more

A critical review of the bioavailability and impacts of heavy metals in municipal solid waste composts compared to sewage sludge.
TL;DR: Low metal materials, which include source-segregated and greenwaste composts, are likely to have inherently lower metal availabilities overall, at equivalent metal loading rates to soil, compared to composted residuals with larger metal contents.

Long-term effects of metals in sewage sludge on soils, microorganisms and plants
TL;DR: It is concluded that prevention of adverse effects on soil microbial processes and ultimately soil fertility, should be a factor which influences soil protection legislation.

Cadmium accumulation in populations of Thlaspi caerulescens and Thlaspi goesingense
TL;DR: This is the first report of hyperaccumulation of Cd by T. goesingense, but the growth of this species was markedly reduced by the large concentrations of Zn in the substrate, indicating that the mechanisms of CD and Zn hyperaccUMulation are not identical in this species.
Journal ArticleDOI
Field evaluation of Cd and Zn phytoextraction potential by the hyperaccumulators Thlaspi caerulescens and Arabidopsis halleri.
TL;DR: The results indicate that metal phytoextraction using T. caerulescens can be used to clean up soils moderately contaminated by Cd.

TL;DR: Zinc, Cu and Ni appear to be the elements most likely to give rise to toxicity problems in plants due to the use of sewage sludge as a soil additive.

TL;DR: In this paper, a 2-year period from eight Indiana cities was analyzed for C, N, P, K, Ca, Mg, Fe, Cd, Zn, Cu, Ni, and Pb.

TL;DR: An analytical survey of 68 elements, dieldrin, and polychlorinated biphenyls (PCB's) was conducted in municipal sewage sludges sampled during 1972-73 from 16 American cities using several instrumental methods.
