Abstract

Background & Objectives 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. Materials & Methods This study is a descriptive cross-sectional that in sampling was two-stage in September 2014 and October 2015. Among total from 2 composting pile, compound sampling based, 26 sample 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. The results were analyzed by using Excel and SPSS software. Results The heavy metals examined in the composted pistachio hull mixed with livestock waste were as follows: pb as 67. 09, Cr as 49. 58 Cd as 2. 84, Cu as 107. 95, Zn as 188. 24, Ni as 79. 75 (mg/kg dw), respectively. Compare the average concentration of heavy metals in samples with Iran and EPA Astandrads showing concentrations of heavy metals in all samples (except metal cu) are less than the standard limit. Conclusion Based on the results, compost produced from pistachio skin and livestock waste the of heavy metals hygienic standards adhered to and usability of its environmental objectives.
