“…Heavy metals associated with crude oil include Pb, Cd, Cu, Zn, Ni, V and Cr amongst others [24]. Diseases and pathological conditions related to heavy metal contaminants have been recently reviewed by Izah et al [10], Izah and Srivastav [11]. The aim of this study was to assess the surface water quality of the Middleton river using heavy metals as pollution indicators.…”

This study was aimed at assessing the bioavailability of heavy metals in the surface water of the Middleton river which is a tributary of the river Nun located in the Niger Delta area of Nigeria. Samples were collected at points within and around oil and gas installations in the area while control points were chosen farther from identified pollution point sources. Three replicate samples were collected for each sampling and control location on a biannual basis for two months (March and August 2017) to reflect the dry and wet seasons respectively. A total of forty-two surface water samples were analyzed for heavy metals using standard methods as given in APHA. Heavy metal variables which were examined indicated significant difference between the locations and the two seasons under study (p<0.05). Dry season heavy metals mean were: Fe (6.55 ± 2.36 mg/l and 7.39 ± 1.35 mg/l); Cr (0.43 ± 0.09 mg/l and 0.34 ± 0.02 mg/l); Mn (0.22 ± 0.31 mg/l and 0.02 ± <0.01 mg/l) and Zn (0.04 ± 0.03 mg/l and 0.01 ± <0.01 mg/l) representing five sampling and two control locations respectively. Wet season heavy metal mean levels were relatively lower when compared to the dry season and depicted values of Fe (4.91 ± 2.55 mg/l and 5.46 ± 2.09 mg/l); Cr (0.27 ± 0.05 mg/l and 0.23 ± 0.01 mg/l); Mn (0.13 ± 0.25 mg/l and <0.01 ± <0.01 mg/l) and Zn (0.01 ± 0.01 mg/l and <0.01 ± <0.01 mg/l) across five sampling and two control locations respectively. All other heavy metals analyzed such as Cd, Ni, Co, Pb, and Cu was found to be below the detection limit of the GBC Avanta PM A6600 -Flame Atomic Absorption Spectrophotometer. The iron and chromium levels found in the Middleton river exceeded permissible limits of DPR, FME, WHO and NESREA while chromium and zinc were within permissible limits of regulatory stipulations. Lower concentration of heavy metals in the wet season could be due to dilution effects while the absence of undetected heavy metals may depict that activities leaching out this heavy metals are not common in the study area.

“…The occurrence of heavy metals in the sediment far above the concentration in the water suggests the ability of materials including decomposing plants and animals and constituents of various wastes stream to accumulate at the sediment. The occurrence of heavy metals in the environment is typically from several anthropogenic activities resulting from urbanization, industrialization and geologic processes (Butu and Iguisi, 2013;Izah et al, 2016). The levels of some heavy metals in tissue of Eichhornia crassipes from Kolo creek are presented in Table 3.…”

“…Some of these include aquatic reptiles, snakes, birds, mammals etc. Nigeria has several water resources including surface and ground water (Izah and Srivastav, 2015;Izah and Ineyougha, 2015;Izah et al, 2016;Seiyaboh et al, 2017a, b). Nigerian surface water resources include fresh water (river, stream, pond, lakes, creek, creeklets), brackish/estuaries (salt and fresh water interphase) and marine (salt water) Agedah et al, 2015;Izah and Srivastav, 2015;Ogamba et al, 2015 a-c;Seiyaboh et al, 2017b).…”

Nigeria is World leading producer of cassava accounting for about 20% of global output. Rudimentary equipment is used for cassava processing into several products such as high quality cassava flour by smallholders that dominate the cassava processing sector in Nigeria. The properties of the wastewater (cassava mill effluents) often exceed the limits for effluents to be discharge into the environment (land and surface water) as specified by Federal Environmental Protection Agency. Cassava mill effluents induce toxicological effects on the environment and its associated biota such as fisheries, flora and fauna as well as humans. This study evaluated the capacity of Saccharomyces cerevisiae isolated from palm wine to remove heavy metals in cassava mill effluents. The S. cerevisiae was identified using conventional microbiological techniques based on their cultural, morphological and physiological/biochemical characteristics. S. cerevisiae was inoculated into the sterile effluent and incubated for 15 days and triplicate sample were withdrawn at 5 days interval for analysis. The samples were prepared and analyzed using flame atomic adsorption spectrometry. Results showed a decline by 44.52%, 26.26%, 51.54%, 43.20% and 65.19% for copper, zinc, manganese, iron and nickel respectively. The findings of this study showed that S. cerevisiae is a potential microorganism for the remediation of heavy metals in cassava mill effluents. Keywords:
