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.

Indoor environmental conditions of selected shopping malls in Nigeria: A comparative study of microclimatic conditions, noise levels, and microbial burdens.

The activities of people and equipment used within shopping malls are major factors that contribute to air pollution and increased sound levels, thereby affecting indoor environmental quality and the well-being of mall operators. This study assessed indoor environmental quality through microbial characterization and measurement of environmental conditions present in selected shopping malls. Investigations were conducted at three shopping malls in Ibadan selected through convenience sampling technique.

Sanitary conditions, waste management, safety measures and sources of air pollution associated with shopping malls in Nigeria's largest city.

Objectives: Shopping malls are fast becoming one of the most visited public spaces globally. However, information on the possible environmental conditions in relation to health hazards in shopping malls is poorly documented in developing countries. This study assessed the sanitary conditions, waste management, safety measures and sources of air pollution associated with selected shopping malls in Nigeria.

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.

Health Risk Assessment of Heavy Metal Pollution in Groundwater Around an Exposed Dumpsite in Southwestern Nigeria.

Background: Groundwater quality can be poor in Nigeria due to indiscriminate refuse dumping. Exposed dumps serve as point source pollution that discharge potentially toxic heavy metals into the environment.

Objectives: The present research aimed to assess the impact of metal pollution on groundwater quality in hand-dug wells around an active dumpsite and to evaluate the long-term human health effects of this pollution.
