Hydro-geochemical study was carried out to assess the influence of seawater on the chemical composition of groundwater in Badagry, Ikorordu, Epe, and Ondo Water side south western Nigeria. One hundred and ninety two (192) groundwater samples were collected from forty-eight (48) sampling points along the coastlines for four seasons (2015 through 2017). Analyses were carried out using standard procedures. Salinity-related parameters of the groundwater samples showed a range of 5.09–7.29 (pH), 1056–2249 µS/cm (electrical conductivity), 513.30–1439.30 mg/L (total dissolved solid), 43.15–2147 mg/L (alkalinity), 51.5–995. 5 mg/L (Cl−), 2.75–11.75 mg/L (SO42−), 8.78–32.11 mg/L (Na+), 24.42–45.44 mg/L (K+) 0.56–2.75 mg/L (Ca2+), 0.09–5.55 mg/L (Mg2+), and 7.2–39.15 mg/L (Hardness), respectively. Groundwater ionic characters were in order of HCO3− > Cl− > SO42− for anions and K+> Na+ > Ca+ > Mg2+ for cations. Though concentration of bicarbonate was high as expected of inland water, salinity-related parameters were above the acceptable limits. Results revealed that the groundwater samples in the areas have saline water signatory probably as a result of prevailing climate influence (sea-level rise and flooding) which predisposes the users to diverse infections and other cardiovascular diseases associated with intake of saltwater. Water quality index also showed that groundwater in the areas are contaminated and unfit for human consumption. Achieving water sustainability in the area would demand appropriate water safety plan and proper water treatment.

This has lead to the degradation of abiotic and biotic components of these nations ’ ecological systems. Poor industrial waste disposal systems as well as the indiscriminate and inappropriate domestic litter disposal habit have been identified and proved to be basic features in rural settlements, semi-urban areas and urban centers of the developing world. These have seriously contributed to environmental pollution and ecological deterioration. The major reasons for these were identified to be inadequate information and insufficient modern waste disposal facilities. Approach: This study highlighted the use of simple, yet efficient waste disposal techniques and recommends the adequate supply and optimal utilization of trashcan and rubbish drums in private and public places; the consistent and wide use of recyclable m...

The present study evaluated the content and toxicological risk assessment of TEIs in commonly consumed snack/junk foods from Ogun State, Nigeria. TEIs (Pb and Cr) were determined in sixty snack food samples purchased from Ijebu Ode, Ogun State, southwestern Nigeria. The TEIs were analysed in quadruplicates using atomic absorption spectrometry with flame atomization. TEI data were subjected to simple descriptive and inferential statistics. The toxicological risk assessment of TEIs was evaluated for hazard quotient (HQ), hazard index (HI) and cancer risk (CR) using the United States Environmental Protection Agency-Integrated Risk Information System (USEPA-IRIS) model. Data showed the varying Pb levels of 8.22 ± 1.57 mg/kg in sausage to 12.25 ± 4.27 mg/kg in cocoyam chips higher than the permissible limit of the Codex Alimentarius of the Joint World Health Organization and Food and Agriculture Organization. The toxicological risk assessment revealed the HQs greater than 1.0 for Pb and Cr in most snack foods consumed by adults and children, indicating adverse health problems. The CRs of Pb (children) and Cr (adults and children) also breached the acceptable limit of 1.0 × 10-4, signifying possible lifetime development of cancer. It is therefore necessary to periodically monitor the TEIs in snacks to protect the public health.

The study involved 250 respondents (151 males and 99 females). It emp loyed a questionnaire in obtaining informat ion fro m the respondents and the data obtained was analyzed using frequency counts and t-test statistics. The result showed that there were no significant differences in the perception of respondents concerning measures taken in controlling flood along the Ogunpa river. Reco mmendations were made as to how the current measures can be more effective.

The natural coagulant was Moringa oleifera seeds (a forest plant) i.e Treatment ‘A’ while the chemical used was Aluminum hydroxide chloride i.e Treatment ‘B’. The aim of this study was to compare the use of a natural coagulant with a chemical coagulant. Samples were collected at Omida, Ibara, Mama Cass, Mr Bigg’s and Sidipon village respectively. The filtrate of Moringa oleifera seed extract was dosed into the greywater sample at 10% dosing range and made to run through a greywater treatment plant while Aluminum Hydroxide Chloride was also dosed at 10% dosing range and made to run through the treatment plant respectively. The greywater treatment plant is a self designed treatment plant made to treat both water and wastewater. The raw water was firstly analyzed, after which the treated samples were taken to the laboratory for analysis. Result for the physical, chemical and bacteriol...
