In the study, health risk assessment on heavy metals ingestion was presented through the groundwater drinking pathway for residents in an oil and gas producing area of Rivers State, Nigeria. The level of the ground water pollution was examined, the quality of the borehole and the well water was assessed and the quality of the ground water pathway for the resident in the oil and gas producing area was determined and compared with the national and international standards for the drinking water. This study adopted both the field and laboratory experimental analysis of physical and chemical parameters. Water samples were analyzed for Physico-chemical parameters following acceptable methods to determine the compliance, and the results were analyzed according to drinking water guidelines. Interestingly, the results show that the ground water contained high amounts of turbidity (21.5 NTU, 23.00 NTU and 19.0 NTU in the borehole water and well water), iron (5.3 mg/L in the ground water and 6.98 mg/L in the borehole water) and pHs of all water samples were acidic in the study area. These results show that ground waters including the borehole and the well waters of the study area had acquired reasonable levels of pollution. Whereas, other values were found to be lower or above and corHow to cite this paper: Olalekan, R.M.,

Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also altering, which has an impact on aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies were incorporated in this research. In light of this, the purpose of the current study is to comprehend how the hydro-geochemistry and appropriateness of surface water for drinking and irrigation vary on a monthly basis. The study employed standardized analytical techniques. According to APHA recommendations, all sampling, conservation, transportation, and analysis were completed (2012). All collected samples were transported to the study lab while being kept in an icebox to prevent the degradation of the organic components. As a result, the study is focused on the contamination level in the surface water for a year. Overall, the study also highlights important pollutants that have an impact on the quality of the surface water as it passes through Osun State's gold mining regions. Finally, it has been determined that the following criteria are crucial for the stretch in each season of this research: DO, Hardness, Turbidity, Chloride, Potassium, Lead, TSS, Cadmium, Chromium, Manganese, Mercury, and Arsenic. Most of the physicochemical variables examined in this study fell within their corresponding standard limits. Based on the results of this study, the appropriate constituted authority is encouraged to continuously monitor and assess surface water quality suitability for drinking, domestic, and irrigation purposes in order to keep track of the effects of water contaminants and detect any changes in the water quality. To safeguard and maintain the groundwater quality and public health, it is advised that appropriate regulatory policies and water treatment procedures be employed in the area. Additionally, it is proposed that when enhancing water quality and investigating the sustainable use of water resources, surface water pollution should be taken into consideration. More research on report quality needs to be done in Nigeria's other mining environments in order to develop technical capacity. In the context of new contaminants and a changing climate, this study suggests additional research directions to enhance knowledge of surface water in a mining setting and sustainable surface water management in mining areas.

Background A crucial issue directly affecting the wellbeing of the human race is water quality. Within a few decades, a greater reliance on groundwater was needed to supply water for drinking, agriculture, and other uses due to the scarcity and contamination of surface water. To forecast its long-term use and increase output, irrigated agriculture requires high-quality water, which must be measured. Objective The goals of the current study are to comprehend the hydro-geochemistry, drinking water appropriateness, and occurrence of hydro-geochemistry concepts in the groundwater of the gold mining regions of Osun State, South-West Nigeria. Method Standardized analytical methods were used in the research. All sampling, conservation, transportation, and analysis were carried out in accordance with APHA guidelines (2012). To prevent deterioration of the organic compounds, all acquired samples were sent to research laboratory, while maintaining in an icebox. Results The study also identifies critical pollutants, affecting the ground water quality within its course through the gold mining areas of Osun State. Finally, Colour, pH, DO, EC, TDS, TSS, TS, Hardness, Magnesium, Nitrate, Phosphate, Lead, Cadmium, Chromium, Manganese, Mercury and Arsenic have been found to be critical parameters for the stretch in each season of this research. Conclusion The authors advise developing ongoing systems for monitoring water quality as well as efficient management techniques to prevent excessive groundwater pollution. These findings will therefore aid decision-makers in managing pollution in Osun State's gold mining zones and better understanding the impact of different seasons on water quality. The findings of this study can serve as a foundation for the future monitoring of the effects of anthropogenic activities on local watercourses when mining companies are developed. This requires consideration in terms of both regulatory measures and proactive initiatives for addressing the ensuing issues in the future. In order to maintain sustainability, a long-term monitoring plan is suggested in this study to be implemented into the groundwater bodies to restore their quality.

This study was designed to essentially determine the relationship between socio-demographic factors and contraceptive use. This was with the view of identifying existing barriers to contraceptive use in the county. The study adopted a community-based, descriptive cross-sectional study. The target population was women of reproductive age, 15 to 49 years living in Ijero Local Government Area of Ekiti State. Using the sample size calculation formula, a sample of 250 women was randomly selected for the study. Data was collected using questionnaires translated and back-translated between the English and the local Yoruba language. Data analysis was performed using SPSS version 20 to generate descriptive and inferential statistics such as contingency tables and bar charts. Chi square was used to find relationship between non parametric variables by testing for association at 5% (p=0, 05) level of significance. Key findings of the study reveals that respondents were young adults and largely in their reproductive age span, more than three-quarters were Christian, more than two-fifths have secondary school education; 76.8% of the sample were working; nine out of every ten women have heard about contraceptives, many respondents have used at least one type of conceptive method, Injections method was the most popular conceptive method among the respondents, and more than 30.4% of the respondents heard about contraceptives through television. Results further show that: women have considerable knowledge on different aspects of the modern contraceptives, 89.6% of women were of the view that modern contraceptive prevents unwanted pregnancy; 39.2% perceived modern contraceptive as something that can boost husband fidelity (39.2%); the most common negative effect of modern contraceptives reported is irregular menstruation among the users; and women in the study area have used injections (22%) and condoms (20.8%) more than any other modern contraceptive methods.
