AGRICULTURAL BENEFITS AND TOXICITY OF ANIMAL BONE ASHES: CHEMICAL COMPOSITION ANALYSIS

Abstract

The problem facing today, mostly in developing country is the deposits of wastes materials especially from meat industry. An emerging issue in world is the growing environmental treat caused by animal wastes. People slaughter animals for their economic product or other purposes and throw away the byproduct without knowing the problem come after it. To reduce this pollution the way of disposing wastes and recycling it in to other raw material is studied. The bone sample were collected and digested for the determination of their mineral constituents by Atomic Absorption and Ultra Violet Visible instruments. On the other hand, the waste material produced from animal wastes can be recycled and changed to raw material for soil amendments for plant growth. To be environmentally eco-friendly the sanction way of west disposal is advisable to use. In this study the content of bone ash sample indicates the presence of essential elements such as Calcium (4013±0.3), Potassium (137±0.007 and Phosphorus (1062.3±30.78) while there is in low amount some toxic metals or heavy metals such as Lead (37±0.0084), Cadmium (32.6±0.00034) and Zinc (179±0.0034).
