چکیده مقاله:
Background and purpose: The most important parameter is heavy metal contents in compost production technology. These heavy metals residue from substances like soap, detergents, cosmetics, packaging, leather and butteries are existed in municipal solid waste. The heavy metals can produce toxin for animal, human and plant. The aim of this research was study of produced compost quality based on heavy metals (Pb, Cd and Zn) in Babol compost plant in ۲۰۱۲.
Materials and Methods: The present research is a descriptive- cross sectional study in which was performed in six months. Total sample numbers (۵ samples) were randomly provided from final compost of Babol plant and then after extraction and filtration, the concentration of heavy metals like cadmium, lead and zinc was measured by atomic absorption spectrophotometer PG- ۹۹۹.
Results: In analyzed samples the maximum, minimum and average of cadmium in the final compost were ۷.۲۵, ۰.۴۷ and ۱.۹ mg/kg. The maximum, minimum and mean of lead were ۲۳۹.۲, ۳۱.۹ and ۶۷.۱ mg/kg; in zinc were ۹۷۲.۷, ۴۸۳.۵ and ۶۰۳.۷ mg/kg respectively.
Conclusion: The concentration of heavy metals in Babol compost samples was under Iranian national and World Health Organization standards and could be used for different species of plants. However, the usability of compost depends on other parameters such as carbon to nitrogen and other components like glass, plastics and textiles.
