Leachate pollution of Aneakie Obiakor illegal dumpsite, Awka was studied. Leachate and plant samples (cassava and pawpaw) were collected from the waste dumpsite and control site during wet season, and analysed for level of concentration of 10 heavy metals; Cd, Zn, Cu, Ni, Pb, As, Hg, Cr, Fe using Atomic Absorption Spectrophotometric (AAS). The result was compared with the control and WHO/FAO st...

Introduction Modern landfills are highly engineered containment systems, designed to minimize the impact of solid waste (refuse, trash, and garbage) on the environment and human health. In modern landfills, the waste is contained by a liner system. The primary purpose of the liner system is to isolate the landfill contents from the environment and, therefore, to protect the soil and ground wate...

To effectively combat the biodiversity crisis, we need ambitious targets and reliable indicators to accurately track trends measure conservation impact. In Canada, Living Planet Index (LPI) has been adapted produce a national indicator by both World Wildlife Fund-Canada (Canadian Index; C-LPI) Environment Climate Change Canada Species Index) provide insight into status of Canadian wildlife, eva...

The quantity of leachate is crucial when assessing pollution emanating from municipal landfills. In most cases, existing leachate quantification measures only take into account one source - precipitation, which resulted in serious underestimation in China due to its waste properties: high moisture contents. To overcome this problem, a new estimation method was established considering two source...

BACKGROUND No instruments, to our knowledge, exist to assess leadership competency in existing and emerging allied health professional (AHP) leaders. This paper describes the development and preliminary exploration of the psychometric properties of a leadership competency instrument for existing and emerging AHP leaders and examines (i) its factor structure, (ii) its convergent validity with th...

Leachate and groundwater samples were collected from Gazipur landfill-site and its adjacent area to study the possible impact of leachate percolation on groundwater quality. Concentration of various physico-chemical parameters including heavy metal (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform (TC) and faecal coliform (FC)) were determined in groundwater and lea...

In most countries, sanitary landfilling is nowadays the most common way to eliminate municipal solid wastes (MSW). In spite of many advantages, generation of heavily polluted leachates, presenting significant variations in both volumetric flow and chemical composition, constitutes a major drawback. Year after year, the recognition of landfill leachate impact on environment has forced authoritie...

Lysinuric protein intolerance (LPI) is a rare autosomal recessive inborn error of metabolism caused by mutations in SLC7A7, which encodes a component of the dibasic amino acid transporter found in intestinal and renal tubular cells. Patients typically present with vomiting, diarrhea, irritability, failure to thrive, and symptomatic hyperammonemia after protein-rich meals. Long-term complication...
