This study was carried out to evaluate the pollution status in water, sediments and whole body tissue of clam (galatea paradoxa, born 1778) of the Diebu Creek, Bayelsa State, Niger Delta Region, Nigeria. The concentrations of the five heavy metals (As, Co, Cu, Fe and Pb) were determined using analyst 400 Perkin Elmer Atomic Absorption Spectrophotometer (AAS). The mean concentration(mg/kg) of the metals in sediment were: (0.66±0.76) Co, (1.56±1.16)Cu, (1812.31±190.31)Fe and (0.94±0.87)Pb, while the mean concentration(mg/kg) of the metals in clam followed decreasing order: Fe(284.22)> Pb(2.30)> Co(1.08)>Cu(0.75) respectively. In attempt to infer anthropogenic input from natural input, linear regression equation, comparison with sediment quality guideline (SQGs) and ecotoxicological sense of heavy metal contamination was employed. The concentration of the studied heavy metals of the Diebu Creek, Fe and Pb exceeded reference standards, however, the concentration does not pose a threat to the sediment dwelling fauna and anyone who consumes aquatic animals particularly clam (galatea paradoxa, born 1778) from the Diebu Creek. According the SQGs, the studied heavy metals of the Diebu Creek sediment were under the category of non-polluted.

“…After cooling, 2.5 mL of 70 % HClO4 was added, and the mixture was gently boiled until dense white fumes appeared. Later, the mixture was allowed to cool, and 10 mL of deionized water was added followed by further boiling until the fumes were totally released according to standard method by [15,16].…”

“…One gram of dried material was digested with 12 ml of HCl: HNO 3 (1:3) to remove all organic matter from the plant samples. After digestion, the residue was washed with distilled water and filtered into a 50-ml volumetric flask and topped to the mark to await further analysis using an FAAS (Kumari, Parida, Rangani, & Panda, 2017;Thangaraj, 2016;Uddin et al, 2016;Yami, Chandravanshi, Wondimu, & Abuye, 2016).…”

Wild indigenous vegetables make considerable contributions to food baskets among subsistence farmers in sub‐Saharan Africa. The aim of this study was to evaluate the proximate analysis, mineral composition, vitamin C content, β‐carotene content, and GC‐MS profile of crude methanolic extracts of Asystasia mysorensis and Sesamum angustifolia . Crude extracts obtained through sequential extraction using ethyl acetate and methanol were screened for the presence of secondary metabolites. Functional groups present were determined with a Shimadzu FT‐IR spectrophotometer, while β‐carotene content and ascorbic acid content were evaluated using a Shimadzu HPLC and Shimadzu UV‐VIS spectrophotometer, respectively. Secondary metabolites present in the extracts were determined qualitatively using a Shimadzu GC‐MS system equipped with a NIST spectral database. From the results obtained, the two plants could supply the recommended daily requirement for micronutrient and vitamin C content needed for a healthy diet. The total phenolic and flavonoid contents in S. amgustifolia were higher as compared to A. myorensis; hence, their consumption is highly beneficial as some compounds identified in the GC‐MS profile have been reported to have medicinal properties. The findings on the mineral and chemical composition, GC‐MS profile of A. mysorensis and S. angustifolia indicate that their consumption may provide the recommended nutritional requirements needed for a healthy diet.

Purpose Utilization of food waste as composting materials offers a sustainable solution to manage waste and reduce reliance on fertilizers. Method This study is focused on the efficiency of food waste compost and the effect of the addition of magnetite (Fe 3 O 4 ) nanoparticles on the growth and heavy metals uptake by roselle (Hibiscus sabdariffa) for the cultivation period of 127 days. Five different treatments were applied, namely soil (S), food waste compost (F), a mixture of soil and Fe 3 O 4 (SM), a mixture of soil and food waste compost (SF), and a mixture of soil, food waste compost, and Fe 3 O 4 (SFM). Results After 127 days of cultivation, the plant height averaged at 803 mm with 26 leaves produced across all treatments. Total leaf area, fruit production, and biomass yield were different (P < 0.05) among the treatments. Roselle crops grown under soil and food waste (SF) media produced the highest yield (12.15 g/plant), the most number of fruits (11 fruits/plant), and the highest leaf area (1200 cm 2 /plant). The accumulation of heavy metals in plant tissues was lower than the toxicity levels. There was no difference in the heavy metal content in all growing media, except for Ni, Mn, and Pb. Roselle crops applied with Fe 3 O 4 showed no difference (P > 0.05) from its control (without Fe 3 O 4 ) in relation to growth performance. Conclusion The findings of this study showed that food waste can be applied in composting to promote plant growth. Therefore, it can be considered as a substitute for chemical fertilizers. Meanwhile, the application of Fe 3 O 4 appeared to be experimental-condition dependent.
