Abstract: Singed and unsinged cow skin (pelts), from four slaughter houses (Ishiodu, Eliozu, Rumuosi, and Rumuodumaya); sold and consumed in Portharcourt, Rivers State city - were evaluated for the concentration of PAHs, TPH and heavy-metals, using GC/FID and atomic absorption spectrophotometer respectively and the outcomes were then exposed to statistical examination (Spearman connection coefficient framework and One-Way ANOVA) to decide critical distinction between the singed and unsinged samples utilizing SPSS programming bundle (form 20.0). The total PAHs and TPH of singed cattle pelts were 0.023, 0.031, 0.035, and 0.035 mg/kg; 1.63, 2.16, 2.52, and 2.62 mg/kg for Ishiodu, Eliozu, Rumuosi, and Rumuodumaya slaughter houses respectively, of which the unsinged pelts and edible-flesh were pointedly (p<0.05) higher than the singed samples. The Fe, Cu, Cd, Zn, Cr, Pb contents were pointedly beyond the passable boundary while Aluminum, Arsenic, and BTEX were not detected. Mercury (Hg) was essentially not identified in singed samples purchased from the slaughter houses with the exclusion of Rumuodumaya (at 0.01mg/kg). The processing procedures aided with certain environmental activities impact negatively on the nutritional content of foods, thus placing consumers at potential wellbeing hazard.

Abstract: For industrial, agricultural, and drinking needs in inland regions, rivers and lakes serve as the main water sources. The factors that impact water quality on a chemical, physical, and biological level are always important. The microbiological quality is crucial and must never be sacrificed in order to provide visually appealing and acceptable water. The most important water quality properties—temperature, pH, turbidity, conductivity, total dissolved solids, total suspended solids, heavy metals, chlorides, nitrates, fluorides, sulfates, bacteria, COD, BOD, DO, etc.—are basic evaluation parameters. This study aimed to review the physicochemical characteristics of water quality in selected areas of Ethiopia. The concentration of those physicochemical properties in water was compared with WHO permissible levels. As a result, turbidity, K, and Na were found beyond WHO permissible levels and the others were found within the acceptable range. Existence beyond acceptable range is a result of daily human activity, the lake closest to the city, and poor household waste management. From this study, we recommend that it is better to study water quality assessment properly and regularly. It's also suggested to create an effective waste management system and prevent the untreated discharge of industrial waste into nearby lakes and rivers. Likewise, creating and raising awareness about treating water with modern waste management technologies is also important.
