Investigation of Some Freshwater Snails as Bioindicator for Heavy Metals

The term “heavy metals” was in use as far back as 1817, when Gmelin divided elements into non-metals, light metals and heavy metals (Habashi, 2009). Over the past two decades, the term “heavy metals” has been used increasingly in various publications and in legislation related to chemical hazards and the safe use of chemicals (Duffus, 2001). Criteria adopted to define heavy metals have included density, atomic weight, atomic number, or periodic table position (Duffus, 2002). [Read more…]

Geology and Hydrochemical Characteristics of Surface Water in Okpo-ihechiowa Arochukwu

The major source of water for all purpose in life is surface water, which has grossly become inadequate because of rapidly increasing demand for water due to urbanization. Prospecting for steady and reliable water supply from subsurface or ground water will rescue the nation from acute shortage of water. The quality of water is determined by its physical, chemical and biological characteristics. [Read more…]

Effect of Coconut Water (Cocos Nucifera) as an Alternative and Local Source of Plant Growth Hormones and Undefined Nutrient for Ginger Tissue Culture

Effect of Coconut Water (Cocos Nucifera) as an Alternative and Local Source of Plant Growth Hormones and Undefined Nutrient for Ginger Tissue Culture

Ginger is an essential cash crop in Nigeria whose production and propagation is on the decline despite our abundant land and human resources. Ginger production is about 2.5 tons/hectare against the required 3.4 tons/hectare estimated to meet the medicinal and confectionary needs and there has been consistent decline in the production (FAO, 2009).
