Opis:
In a three year study (2018, 2019 and 2020), some groundwater sources in Ota, Ogun State, Nigeria were evaluated for quality. A total of one hundred and eighty composite borehole water samples were collected from 10 locations/sites in the study area. The sampling sites in the study were A (Iju), B (Onipannu), C (Ilogbo), D (Arobieye), E (Igbooloye, F (Osi), G (Ijoko), H (Akeja), I (Oju-ore) and J (Iyesi). Samples collected were analyzed using standard procedure for pH, electrical conductivity (EC), total dissolved solids (TDS), chloride and iron (Fe). Results over three years showed that the water was acidic with pH < 6.5, EC ranged from 39.52±0.79 to 134.99±0.03 µS/cm, TDS ranged from 19.43±0.42 to 81.00±0.02 mg/L, chloride was consistent at 0.02±0.00 mg/L while Fe ranged from 0.00±0.00 to 0.11±0.08 mg/L. There was no definite yearly trend except for Fe which dropped from 0.036 mg/L in 2018 to 0.011 mg/L in 2020. Modelling the data for consumption using water quality index (WQI) showed that the groundwater is of excellent quality with WQI < 50 while for health risks using the average daily dose (ADD) and hazard quotient showed that the groundwater would pose no non-carcinogenic risks. Periodic monitoring covering more parameter is recommended to reflect the proper status of groundwater sources in Ota.

Opis:
Palm oil is the most commonly used vegetable oil in Nigeria due to its numerous benefits. Therefore, it is very important to investigate the quality of palm oil. In this study, oil samples were collected from different oil mills in Imo state. Physical and chemical properties of the oil samples were evaluated using standard procedures. The result showed that the moisture content ranged from 0.26% to 0.33%, specific gravity ranged from 0.8900 to 0.9250 while the density ranged from 0.8700 g/ml to 0.9100 g/ml. The saponification value (SV), Free fatty acid and Acid value ranged from 192.49 mg KOH/g to 202.73 mg KOH/g, 10.38 mg KOH/g to 18.80 mg KOH/g and 20.76 mg/g to 37.59 mg/g respectively, while the Smoke point and Refractive index ranged from 114.0 °C to 116.2 °C and 1.4615°Bx to 1.4640°Bx respectively. The peroxide value, Iodine value and Ester value ranged from 14.10 mEq./g to 24.80 mEq./g, 0.48wij’s to 2.84wij’s and 160.86 to 172.86 respectively. All samples showed > 35% SV suggesting the palm oil will be good in soap production. It is recommended that oil palm factories in Imo state processing and storage method should be properly monitored to prevent major contamination or adulteration which might have an adverse effect on the future of oil palm industry in Imo state, Nigeria.
