Environmental pollution has become a worldwide challenge due to industrialisation and anthropogenic activities. Industrial effluents cause a wide scope of environmental problems with health hazards and these challenges are more complex and critical now than before, in developing countries like Nigeria. This study assessed the impact of environmental pollution and determined levels of heavy metals (HMs) in the effluents from tannery industries in Sharada phase I and II. The data used include laboratory test to determine heavy metals (Cd, Cr, Cu, Pb, Zn, Ni, Mn, Fe), Electrical Conductivity (EC) and Total Dissolved Solid (TDS) from industrial effluents. Interview was conducted and systematic field observation was employed to ascertain the perceptible impacts of the pollution on the environment. The finding reveals that concentrations of the physicochemical parameters are within the FEPA acceptable limits but the EC and TDS are above the limit. The pH value of the effluents is neutral. The major conspicuous and dangerous environmental challenges in the study area include air pollution and open drainages. The economic activities of the residents are negatively affected due to stink from the effluents and untidy environment. The environment has become detrimental to people’s health and the passerby. Thus, FEPA laws should be enforced, the industries should construct closed drainage, study on environmental impact assessment (EIA) should be conducted often to curtail the environmental challenges in the area in order to make the environment conducive for living, avoid further deterioration and ensure a sustainable hygienic environment.

Globally, malaria increase the rate maternal mortality. Nigeria has high malaria endemicity and the world's highest malaria burden. Nigeria reports about 51 million cases and 31.3% mortality annually, while 97% of the population (213.4m) is at risk. Malaria killed no fewer than 200,000 Nigerians, of which there were 61 million cases that were responsible for 11% of maternal mortality in Nigeria in 2021. This study examined the prevalence and patterns of malaria endemicity among pregnant women in Ondo State, and determined the malaria prevalence from 2013–2017. Geospatial technology was employed to examine the distribution of malaria cases among pregnant women and one-way Analysis of Variance (ANOVA) was used to determine the malaria prevalence in eight Local Government Areas. Temporal analysis revealed a gradual increase in malaria occurrence over the years. In 2013, 2015, and 2017, Akure South recorded the highest prevalence, with approximately 8 cases (40.11%), 5 cases (23.64%), and 9 cases (27.94%) per 1000 pregnant women, respectively. Ondo East had the highest prevalence of 9 cases (27.06%) in 2014, while in 2016, Akoko Southwest had the highest prevalence of 3 cases (19.04%) per 1000 pregnant women. The cumulative malaria patterns for the five years showed that Akure South had the highest prevalence of 18.76–31.42 per 1000 pregnant women. In contrast, the lowest prevalence occurred in Odigbo and Okitipupa having 5–9 cases per 1000 pregnant women. From 2013–2017, findings showed variations in the disease's prevalence in Ondo state.
