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.

Opis:
Microplastic (MP, 1 μm − 5 mm) pollution has become a global environmental concern with potential risk to ecosystem and human health. Information on the accumulation of MPs in aquatic species has been well documented, while information on the uptake and accumulation of MPs by higher plants is still very scarce. Terrestrial edible plants are directly exposed to MPs when soil was applied with sludge, organic fertilizer, plastic mulching, waste water irrigation, plastic littering, surface runoff or from atmospheric deposition of airborne MP. One study using fluorescent marker recently showed that plant can accumulate MP through uptake from MP polluted soil. Thus, potentially contaminating the base of the food-web and also indicating new exposure route to MP ingestion. This review present a discuss of the implication of these findings to human, who may be ingesting an estimated 80 g of MP through eating of plant daily as global consumption rate of plant continually increase. Also, benefit for the terrestrial ecosystem is discussed, by which plant acts as a potential remediator of MP polluted soil either by phytoextraction, phytostabilization and phytofilteration. We conclude by pointing knowledge gap and suggesting key future areas of research for scientists and policymakers.

Opis:
The leaves of mistletoe (Viscum album) harvested from oil bean tree (Pentaclethra macrophylla) in Imo State South Eastern Nigeria was studied. The study was aimed at carrying out trace metal, Fourier Transform Infra-red (FTIR) and phytochemical analysis of ethanol leave extracts of Viscum album harvested from Pentaclethra macrophylla. The sample for trace metal analysis was digested with a mixture of concentrated HNO3 and HClO4 at a ratio of 1:1 for 24 hours. Ethanol was then used to extract the sample meant for FTIR and phytochemical analysis. Herein, trace metal determination indicates the presence of Mg, Zn, Fe, Cu and Cr, and the concentration of Ca and Mn is at < 0.00 mg/kg. The result of the phytochemical screening demonstrates the presence of flavonoids, alkaloids, phenols, saponins and tannins. FTIR analysis confirmed the presence of alcohols, amides, aromatics and carbonyl compounds in ethanol extracts of Viscum album harvested from Pentaclethra macrophylla. The presence of some trace metals and phytochemicals, as well as some important functional groups in the plant sample, as indicated by the result of the study, authenticates its use in traditional medicine.

Opis:
With increasing population and human activities, dumpsites experience diverse sources of waste with potential radiation hazards. Ionizing radiations have often been overlooked amongst researchers in third world countries, hence, information in this regard is lacking. In this study, nine dumpsites within Imo State University (IMSU) grounds were assessed for radiation levels using Geiger Muller counter Tube Mullard type ZP 1481 with assisted scalar and stopwatch. After calibration, the instrument was placed one meter above ground level and count rates recorded at 10 minutes interval for each location once in the morning, the afternoon and the evening for seven days. Results reveal higher dose equivalents in some morning periods than in the afternoon and evening. Site ETF2 had highest value of 0.69±0.08 mSv·yr-1, while Extension gate had lowest value of 0.56±0.01 mSv·yr-1. Compared to National Council for Radiation Protection maximum permissible level, these values are quite low. In conclusion, ionizing radiations levels at the studied dumpsites in Imo State University grounds are low and may not pose a threat to persons within the university.
