Avaliação quimiométrica da distribuição de metais pesados em composto de lixo urbano domiciliar
Recebido em 23/3/98; aceito em 19/8/98 CHEMOMETRIC EVALUATION OF THE HEAVY METAL DISTRIBUTION IN COMPOST OF DOMICILIARY URBAN GARBAGE. The main obstacle to the use of compost from urban waste in agriculture is the presence of heavy metals. Once in the soil, their effect is accumulative and they may contaminate crops and water. The present study reports the evaluation of the chemical distributions of Cu, Pb, Mn and Zn in three different sized fractions (unsieved, < 1,18mm and > 1,18mm) ofdoi:10.1590/s0100-40421999000300007 fatcat:5nagitjfibfx3g4fqeu47qpuzy
