“…The low values obtained in sediments at various zones of the sampling point can be attributed to river current which moves most of the dissolved metals that should have settled within the river bed. Similar research was conducted on Ore and Okitipupa surface water (Ediagbonya & Ayedun 2018 3). The seasonal distribution of the mean concentration of metal in River Ogbere sediment has been shown in both seasons to be in the order of:…”

Heavy metals are pollutants of river sediments, and their concentration varies depending on parental material and anthropogenic inputs, thus important to distinguish between the natural and anthropogenic inputs. The objective of this study is to use different types of indexes to assess the current pollution status in Ogbere River sediment and select the best index to describe the sediment quality. The indexes used in this study were enrichment factor (EF), geoaccumulation index (Igeo) and principal component analysis (PCA). The PCA has an advantage over other index analyses as it reduces the dimensionality of the data set and thus used to support multivariate cluster analysis. From the study, a total of 12 sediment samples were collected in both seasons across six sampling location and pollution indexes indicated three things: firstly, the metal distribution profile in the sediment showed that the heavy metals analysed for were lower than the maximum allowable limits stipulated by Department of Petroleum Resources (DPR); secondly, minor to extremely severe significant levels of enrichment and thirdly, practically uncontaminated to a moderately contaminated degree of contamination in Ogbere River during the study period. The PCA is considered more sensitive in the analysis of benthic changes and as well as sediment quality. However, the heavy metal assessment indices are not only used for sediment quality. Biological testing and ecological analysis of existing community related to sediment contamination are further recommended in River Ogbere.

“…In contrast, concentrations greater or equal to ERL and less than or equal to ERM, a biological effect occurs on occasion, at concentrations greater or equal to ERM, a negative biological effect occurs on a regular basis, and sediments were expected to be toxic (Nasher et al, 2013, Yuan et al, 2013Ediagbonya & Ayedun 2018a;Ediagbonya & Gbolahan 2018b;Ediagbonya & Balogun 2020). Table 6 shows the mean concentration of each PAH in sediments from the river sample.…”

Polycyclic aromatic hydrocarbons (PAHs) are organic compounds composed of two or more fused aromatic rings. PAHs can be found in a variety of foods and beverages, including drinking water, vegetables, fruits, cereals, oils, seafood, and meats. The current study investigated the pollution levels of the quantum of polycyclic aromatic hydrocarbon in Pyxicephalus edulis and river sediments. Twenty-five sediment samples and male and female specimens of Pyxicephalus edulis were collected from Oluwa River near Igbekebo, Ondo State Nigeria. The sediment samples were then dried in the open air for three days while the identified frog species were dried separately for 6 hours at 105°C before being powdered. The physicochemical parameters of sediment samples examined using standard physical and chemical analytical techniques and polycyclic aromatic hydrocarbons in frog and sediment samples were examined using gas chromatographyflame ionization analysis (GC-FID). The toxicity equivalent(TEQ) values of PAHs in sediment samples were determined by comparing the findings of this study to the Sediment Quality Guideline (SQG) with effects range from viz., low (ERL), median(ERM) and threshold-effects level (TEL)/probable-effects level (PEL) to assess the toxicity of PAHs to aquatic organisms living in sediments. Male frogs had significantly higher concentrations of Acenaphthylene, Phenanthrene, Anthracene, Pyrene, and total PAHs than females, and lower concentrations of Naphthalene, Acenaphthylene, Fluorene, and Fluoranthene. BaAnt, Benzo(b) fluoranthene, Benzo(k)fluoranthrene, Benzo(a)pyrene, Indeno(1,2,3-cd) pyrene, Dibenz(a,h)anthracene, Benzo(g,h,i)perylene were reported only among males. The cause of this variation is unknown, but it could be due to differences in the genetic make-up of male and female frogs.

“…Materials used were fresh poultry waste and saw dusts. The fresh poultry wastes are collected from Agric Reality Farm at Maclean village off Aye road, Okitipupa (Latitude 5.125°N Longitude 4.008°E and Latitude 8.042°N Longitude 6.011°E), Ondo State, Nigeria (Ediagbonya and Ayedun, 2018). The saw dusts were collected from saw mill factory located in Ayeka area, Okitipupa, Ondo State.…”

The high demand for energy as a result of the increase in population and the need to keep our environments clean makes research on biogas from wastes very necessary. The study was conducted to use poultry wastes mixed with sawdust to generate gases that can be used for cooking. The poultry waste was mixed with saw dust in the ratio 4:0, 4:1, 2:1 and 1:1 over a period of 4 weeks. The gases collected were subjected to laboratory analysis using Gas Chromatography of Perkin Elmer model. Methane yields of 3.45 x 10-3m3, 3.05 x 10-3m3, 2.03 x 10-3m3 and 1.00 x 10-3m3 were generated respectively. The more saw dust added the less gas of interest produced. Analysis of residue showed concentrations of N, P, and K in the residue are 0.847 %, 0.28 %, and 2.09 % respectively which implies materials that can be incorporated in soil amendment. Removing saw dust from the environment to generate gas reduces environmental pollution caused by burning.
