Relationship between mobility of heavy metals and humic acid characteristics in two soils treated with sewage sludges


, : Relationship between mobility of heavy metals and humic acid characteristics in two soils treated with sewage sludges. El estudio del suelo y de su degradacion en relacion con la desertificacion Actas del 12 Congreso Latinoamericano de la Ciencia del Suelo, Salamanca, Sevilla Espana 19 a 26 de Septiembre de 1993: 636-640

The physico-chemical characteristics of the humic acids of two soils (Typic Haploxeralf and Typic Chromoxerert) of different texture from Toledo, Spain, previously treated with sewage sludges at a rate of 60 t/ha and incubated for six months, were correlated with the amounts of heavy metals extracted with water and DTPA.

The need is shown for selective extractants to distinguish and estimate the different forms of combination of trace metals that occur when sludge and soil interact. Further development of such extractants is required.
