Contamination, ecological, and human health risks of heavy metals in water from a Pb-Zn-F mining area, North Eastern Nigeria.

In Nigeria, artisanal mining has become a serious issue. In the Nigerian mining region of Arufu Pb-Zn-F, this study assessed the level of pollution, ecological hazards, and health risks related to the presence of metals in the water. In the dry and rainy seasons, 36 water samples (20 from the ground, 10 from the surface, and six from the mine) were gathered.

Potential ecological and health risks of toxic metals associated with artisanal mining contamination in Ijero, southwest Nigeria.

This investigation was done to decide the concentrations, sources and potential risks of metals in media around Ijero area. A total of 80 samples including topsoils, sediments, tailings and whole plants were gathered from this territory while control samples were taken from zone with less human exercises. Samples were pounded, sieved and chemically analyzed utilizing Agilent High Plasma Liquid Chromatography Inductively Coupled Plasma-Mass Spectrometer.

Evaluation of Contamination and Ecological Risk of Heavy Metals Associated with Cement Production in Ewekoro, Southwest Nigeria.

Background: Exposure to heavy metals emanating from cement production and other anthropogenic activities can pose ecological risks.

Objectives: A detailed investigation was carried out to assess the contamination and ecological risk of heavy metals associated with dust released during cement production.

Methods: Sixty samples, including 30 soils and 30 plants, were collected around Lafarge Cement Production Company.
