Abstract
Pistachio hull, a by-product of Pistachio processing, is a source of environmental pollution and can cause the health problems. Therefore, it must be treated by proper, sanitary and economical manners. One of the basic parameters for compost valuation is determine the amount of heavy metals. The objective of the present study was to determiner the concentration of heavy metals (pb, Cd, cr, Zn, Ni, Cu ) in the compost produced from mixed Pistachio Hull and livestock and Compare levels of heavy metals with the limits of international and internal standards.
Material & Methods: This study is a descriptive cross-sectional that in sampling was two-stage in September 2014 and October 2015 A total from 2 composting pile , Compound sampling based ,26sample were selected. After digestion of the samples, the concentrations of metals( Pb ,Cd, Zn,Cr,Cu,Ni) by means of atomic absorption analysis and the concentration of a component in the sample based on mg / kg dw were reported.
