The implications of environmental contamination on human health in the Niger Delta region of Nigeria remain a topic of growing international public health interest. To better understand ongoing air pollution and initiate remediation efforts, the United Nations Environmental Programme (UNEP) report recommended the monitoring of volatile organic compounds (VOCs) across different media (water, soil, and air) in Ogoniland, an at-risk population in the Niger Delta region of Nigeria. In this pilot study, we measured indoor VOC concentrations in the indoor air of 20 households in Ogale, an Ogoniland community whose groundwater system is contaminated with benzene at levels 900 times the World Health Organization guidelines and evaluated self-reported health conditions and predicted cancer risks and hazards from inhalation exposure to VOCs. We detected higher concentrations of benzene (mean = 25.7 μg/m3, SD = 23.2 μg/m3) and naphthalene (mean = 7.6 μg/m3, SD = 13.8 μg/m3) than has been reported in other regions. Although study participants reported health symptoms consistent with VOC exposure, we were underpowered to detect a significant association between select indoor VOCs and these self-reported health symptoms using univariate logistic regression models. These findings suggest that that the health symptoms reported by participants may be poor proxies for the underlying disease processes associated with adverse health outcomes due to VOC exposure in this community and that the burden of adverse health effects due to VOC exposure may stem from the contaminated groundwater system. We estimated a non-cancer hazard quotient of 3 from exposure to naphthalene and lifetime excess cancer risks from exposure to naphthalene, benzene, p-dichlorobenzene, carbon tetrachloride, and ethylbenzene of 3 × 10−4, 2 × 10−4, 6 × 10−5, 6 × 10−6, and 1 × 10−5, respectively. These results exceed common risk benchmarks in the United States, suggesting a need for further studies to characterize VOC exposures, sources, and associated health risks in the Niger Delta.

Pm2.5 Concentration

Due to the visibility of soot in the environment of the Niger Delta especially Rivers State that has led to the increase of  espiratory Tract Infections (RTIs) in the region, this study was undertaken to determine the relationship between Particulate Matter (PM2.5) concentration and the incident of Respiratory Tract Infections (RTIs) in selected urban centres of the Niger Delta. Data on RTIs were collected from the Hospital Management Boards of the Ministries of Health of Rivers, Bayelsa and Delta States and the data for PM2.5 were remotely sensed from 2016 to 2019, and subsequently analyzed with ANOVA and Spearman’s rank correlation statistics. The findings of this study revealed that there was significant variation in the occurrence of PM2.5 across the selected urban centres in the Niger Delta Region. The PM2.5 for the reviewed years was far above the World Health Organization (WHO) annual permissible limit of 10 µg/m3 thereby exacerbating Respiratory Tract Infections (RTIs).The epidemiology of the RTIs showed that there are basically four (4) prominent RTI diseases: Asthma, Tuberculosis, Pneumonia and Chronic Obstructive Pulmonary Disease (COPD). The result of this study showed that the concentration of PM2.5 varies in all the selected cities, and the mean monthly variation (2016-2019) showed that Port Harcourt had 47.27 µg/m3 for January while Yenagoa and Asaba had 46 µg/m3 and 47.51 µg/m3 respectively for January; while the lowest mean value in the cities were seen within the month of September and October, which also had a strong seasonal influence on the concentration of PM2.5. The concentration of PM2.5 and the numbers of RTIs also gradually increases in the study areas from 2016 to 2019. The study recommends that the necessary regulatory bodies should closely monitor the activities of the companies likely to cause such pollution; guild them through their operations and give prompt sanctions and heavy fines to defaulters of the accepted standards.

Abstract The development of insecticide resistance in different species of mosquitoes to Pyrethroids is a major challenge for vector-borne diseases transmitted by mosquitoes. Failure of Pyrethroids in control of mosquitoes would impact negatively on the gains recorded in control of mosquito-borne diseases in previous years. In anticipation of a country-wide deployment of Pyrethroid-treated nets for control of mosquito-borne diseases in Nigeria, this study assessed susceptibility of Culex quinquefasciatus Say. (Diptera: Culicidae) to Pyrethroids in Owhelogbo, Ejeme and Oria-Abraka communities in Delta State, Niger-Delta, Nigeria. Three to five day old Cx. quinquefasciatus were exposed to Deltamethrin (0.05%), Permethrin (0.75%), and Alphacypermethrin (0.05%) using World Health Organization bioassay method. Polymerase chain reaction (PCR) was employed in characterization of species and knockdown mutation. Results revealed that Cx. quinquefasciatus were generally susceptible (98-100%) to Deltamethrin, Permethrin, and Alphacypermethrin in the three communities with the exception of Owhelogbo where resistance to Deltamethrin (97%) was suspected. Knockdown time to Deltamethrin (11.51, 11.23, and 12.68 min), Permethrin (28.75, 13.26, and 14.49 min), and Alphacypermethrin (15.07, 12.50, and 13.03 min) were considerably low for Owhelogbo, Ejeme, and Oria-Abraka Cx. quinquefasciatus populations, respectively. Species identification result showed that all amplified samples were Cx. quinquefasciatus; however, no kdr allele was found in the three populations. Deployment of pyrethroid-treated nets for control of mosquito-borne diseases in Niger-Delta region of Nigeria is capable of reducing burden of diseases transmitted by Cx. quinquefasciatus as well as addressing nuisance value of the vector; however, caution must be entertained so as not to increase selection pressure thereby aiding resistance development.

A number of local butchers in Uyo metropolis usually make use of used scrap car tyres (USCT) and condemned plastics (CPS) as close substitutes for firewood to singe slaughtered ruminants. This study evaluated the effect of singeing materials on the distribution of some metals (Cd, Cr, Ni, Pb, Cu, Zn and Fe) in liver and kidney samples of Capra aegagrus hircus (goat) slaughtered in Uyo Village Road Abattoir in the Niger Delta Region of Nigeria using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). Carcinogenic and non-carcinogenic health risks for children and adults were also estimated using Estimated Chronic Daily Intake (ECDI), Hazard Quotient (HQ) and Hazard Indices (HI) of metals in liver and kidney. Relative to unsinged samples, singed treatments generally demonstrated elevated heavy metal levels in both goat liver and the kidney. Apart from nickel, iron and zinc, the range of values obtained for all the metals in singed samples studied were above the threshold stipulated by the Food and Agricultural Organization and World Health Organization. The health risk assessment revealed Cd, Pb, Ni and Cr as potential carcinogens in the signed samples evaluated. The continuous use of these dangerous materials for singeing of goat meat for human consumption poses great risk to human health and should be discontinued.

This study sought to investigate factors militating against community participation in development projects executed under the Micro Projects Programme and how to reduce such factors to the barest minimum in the Niger Delta region of Nigeria. A cross-sectional survey design was adopted for the study. A questionnaire, an in-depth interview (IDI) guide and a focus group discussion (FGD) guide were used for data collection. Borehole water, generator-house, health centres, staff quarters and markets were the projects executed. Inadequate devolution of power to the grassroots, among others, was the major problem that hindered involvement of community members in the development process of the Micro Projects Programme in the study areas. To enhance active participation of beneficiaries in the development process of the programme, suggestions are proffered.
