Effects of exposure to volatile organic compounds (VOCs) content from paint on automobile paint workers in Nsukka, South Eastern Nigeria.

Background: Volatile organic compounds (VOCs) fume in the workplace can act as an inducing agent to many health disorders.

Objectives: This work investigated the effects of exposure to VOCs content from paint on the automobile paint workers in South Eastern Nigeria.

Methods: A total of fifty (50) respondent participated in the study.

Effect of nickel oxide nanoparticles on bioethanol production by IFM 53048 using banana peel waste substrate.

The use of nanomaterials in bioethanol production is promising and on the increase. In this report, the effect of nickel oxide nanoparticles (NiO NPs) on bioethanol production in the presence of a novel yeast strain, IFM 53048 isolated from banana wastes was investigated. The hot percolation method was employed for the green synthesis of NiO NPs.

Quantitative modelling of Ostracod bioassay: assigning toxicity index to potentially chemical contaminated swimming pools.

One of the primary objectives of any public health programme is to design a protocol that will curtail a population from being predisposed to toxic substances in the environment. Biomarkers help in actualising such an objective by their potential to detect the presence of toxic substances in environmental media such as soil, water and air. The Ostracod Heterocypris incongruens, an already established biomarker for quality evaluation of freshwater, does not quantify toxicity.

Evaluation of Pb concentrations in selected vegetables and portable drinking water, and intelligent quotients of school children in Ishiagu-a Pb mining community: health risk assessment using predictive modelling.

This study evaluates the concentrations of lead (Pb) in 6 selected vegetables and drinking water samples taken from an agricultural/mining town Ishiagu. This evaluation is important because these vegetables and water are major gateway of lead exposure through ingestion, especially children in the Pb mining environment. Pb at even very low concentrations has been shown to have adverse effect on developing brain and hence children's intellectual ability.

Health Implications of Occupational Exposure of Butchers to Emissions from Burning Tyres.

Background: Flames from burning scrap tyres are used in de-furring animals for human consumption in most parts of Nigeria. Emissions from tyres are known to contain a myriad of toxic mixtures especially particulate matter (PM), volatile organic compounds, hazardous air pollutants, and inspirable metals, some of which are known human carcinogens. This cross-sectional study investigated the deleterious health effects of these emissions in occupationally-exposed workers at the Dei-Dei Abattoir, Abuja, Nigeria.
