The enrichment factors (EF) of metals are shown in Fig. 1. EF has been adopted to show the anthropogenic influence of metals in soil,sediment and atmosphere [29]. The EF values of compost provideuseful information on contamination status of finished compostand its suitability for bioremediation and agricultural use.The compost revealed low EF values less than 2.0 for all theanalyzed metals indicating low metal contamination and deple-tion to minimal enrichment [48]. The metals (Mn, Fe, Zn, Cu andCr) observed in this study are essential micronutrients required byplants for growth. The contaminated soil samples were enrichedin Cu and Zn (EF > 5.0) indicating metal pollution by anthropogenicactivities [29]. Cu and Zn enrichment could be attributed to indus-trial and traffic pollution [49]. Emission sources of Cu and ZnFig.
