Research ArticleOpen accessPhrase in the titleUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleHeavy Metals Contamination of Road-Deposited SedimentsJonathan YisaProblem statement: Impact of anthropogenic activities on man and his environment as a result of the growing rate of urbanization in Bida, Nigeria is of a great concern. Street sediments that accumulate along pavements in urban environments have the potential to provide considerable loadings of heavy metals to receiving waters and water bodies, particularly with changing environmental conditions.
