Efficacy of Vermiremediation to Remove Contaminants from Soil.

Background: In addition to improving soil fertility and crop production, earthworms have been found to be useful in the removal of contaminants from soil, known as vermiremediation. Previous studies on vermiremediation have focused primarily on organic wastes, with relatively less attention paid to inorganic contaminants. In addition, some basic terms used in environmental health studies have often not been properly clarified.

Physicochemical and Genotoxic Evaluations of Singed Cowhide Meat () Wastewater.

Introduction: In spite of doubts over the safety and nutritional benefits of singed cowhide meat, called in some parts of Nigeria, and its potential negative impact on the hide and leather industry, consumption in Nigeria and many parts of Africa has continued unabated.

Objectives: In the present study, physicochemical and genotoxic assessments of wastewater used to rinse ready-to-cook singed cowhide meat were carried out.

Methods: Physicochemical analyses were carried out using the American Public Health Association procedures, while genotoxic assessment was carried out using Allium cepa chromosome assay.

Phthalate and Metal Concentrations in Drinking Water in Lagos, Nigeria.

Introduction: There have been no studies, monitoring programs, or data about phthalate levels made available to the public on the safety of residential drinking water in Lagos, Nigeria.

Objectives: The present study aimed to assess the concentrations of dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), and zinc (Zn), lead (Pb), chromium (Cr), and cadmium (Cd) in drinking water drawn from taps in three residential areas of the state.

Methods: High performance liquid chromatography and atomic absorption spectroscopy were used to determine the concentrations of phthalates and metals, respectively.
