adjacent through the mining, processing and tail points. This study is to ascertain the level of Iron-Ore mining impact on River PovPov using heavy metal pollution and metal indices and multivariate statistical methods. Geology: The study area lies within the Benin-Nigeria shield, situated in .
In addition, the tailings contain many heavy metals, some of which are toxic contaminants in the soil that may cause adverse effect on the ecosystem around the metal mines [11–13]. Therefore, contamination of soils, sediments, water and biota by heavy metals is a primary concern in the mining sites because of their toxicity, persistence, and
The environment and its compartments have been severely polluted by heavy metals. This has compromised the ability of the environment to foster life and render its intrinsic values. Heavy metals are known to be naturally occurring compounds, but anthropogenic activities introduce them in large quantities in different environmental compartments.

Geochemical Distribution of Heavy Metals in Soil around Itakpe Iron-ore Mining Area-a Statistical Approach . By E.G. Ameh. Abstract. This study becomes imperative in order to determine the degree of soil contamination due to iron-ore mining. Ten surface soil samples were collected and analyzed for major ions and heavy metals during the dry season.
heavy metals in the inhabitants of these areas. MATERIALS AND METHODS The study took place in Itakpe Iron Mine (7.36 N, 6.61 E) as well as a prosperous mining site Agbaja iron ore site (7.982978 N, 6.649874 E) both in Kogi state. The Itakpe Hills in and around the town of Itakpe contain very pure deposits of iron ore.

A total of 32 composite samples were collected between September and October, 2014 to assess concentrations of heavy metals and pollution levels, as well as cancer and non-cancer risks to human health from exposure to heavy metals from four major mining regions and four rain forest reserves in the Western, Ashanti, Brong Ahafo and Eastern ...
The most common metal pollution in freshwater comes from mining companies. They usually use an acid mine drainage system to release heavy metals from ores, because metals are very soluble in an acid solution. After the drainage process, they disperse the acid solution in the groundwater, containing high levels of metals.
