“…Environmental pollution by heavy metals is of importance owing to their nonbiodegradability, accumulative capabilities and toxicity to life-forms (Purves, 1985;Henry, 2000;Ghosh and Singh, 2005;Neff et al, 2006;Erakhrumen, 2012;Erakhrumen, 2014). Therefore, since metals cannot be degraded, unlike organic compounds, clean-up usually requires their removal from polluted medium (Ghosh and Singh, 2005).…”

Environmental pollution is assuming frightening dimensions in many parts of the world. This is not excluding Niger-Delta region of Nigeria where most of the country's oil and gas are sourced with attendant production of noxious substances as byproducts/residues/waste. Many of these noxious substances have been noted to be removable from polluted environment through proper application of phytoremediation techniques, particularly using native plant species. Consequently, this research was conceived to evaluate potentials for phytomediation by native red mangrove tree (Rhizophora racemosa G.F.W. Meyer). This was carried out by evaluating the presence of heavy metals ions and their bioconcentration levels in the samples of root and wood tissues axially along the stem of this tree. The sorrounding soil and water were also sampled and evaluated for presence and concentration of these metal ions in comparison with those for the sampled plant tissues. All the samples were sourced from a mangrove forest in Okrika, Rivers State, Nigeria. The samples from the root, butt, 50% and 90% bole length were oven-dried at 60±5 o C to constant weight, pulverised and heated with trioxonitrate (v) acid to achieve total dissolution before subjecting them to atomic absorption spectroscopy (AAS). Similarly, samples from sorrouding soil were dried at 35±2 o C to constant weight, crushed and sieved using a ≤ 2mm mesh before performing metal extraction and detection using AAS while water samples were also subjected to AAS for heavy metal analyses, in line with appropriate standard methods. The data obtained were statistically analysed using basic descriptive tools, Analyses of Variance and Fishers' Least Significant Difference (P < 0.05). Outcomes of these statistical analyses showed that, in terms of bio-concentration values, the evaluated metal ions that include Fe, Cu, Mn, Cd, Pb, Ni and Cr were more in the root than the surrounding soil and water. The bio-concentration trends, for the metal ions, also progressively declined from the root towards the crown of the trees. The bio-concentration distribution in all the tree sections showed an inconsistent pattern with Fe ions having higher bio-concentration. In addition, Cr, Ni, Pd and Cu also inconsistently followed Fe in terms of bio-concentration level. © JASEM http://dx

“…As a chronic source of PAH contamination in the marine environment, PW is also a source of concern with respect to possible long term impact on the environment [65]. Estimates of the PW discharge volumes on the Norwegian shelf predict an increase until 2010-2014, reaching a maximum of about 200 million L/year [66].…”

“…Chemical substances present in produced formation water are the focus of management activity, including total hydrocarbon content (THC), aromatics (PAHs, BTEX, and naphthalene), organic acids and phenols; alkylphenols (two groups: C1-C3 and C4-C9); toxic metals (arsenic, lead, cadmium, copper, chromium, mercury, nickel, zinc); radionuclides; and production chemical residuals. Thus, toxic metal quantification in production formation waters is of environmental concern [3][4][5][6].…”

This work approaches the development of a procedure for separation and determination of five trace metals (Co, Cd, Pb, Ni, and Cu) from petroleum produced formation water. This procedure uses a styrene divinyl-benzene polymeric resin modified with 4-(5 -bromo-2 -tiazolilazo) orcinol, and the determination was performed by inductively coupled plasma mass spectrometry. A response surface methodology using a Doehlert matrix was used to optimize the solid-phase extraction of the studied elements. By using 50.0 mL of sample solution for separation/preconcentration, limits of quantification of 2.4, 14, 10, 11, and 350 ng L −1 were obtained for Co, Cd, Pb, Ni, and Cu, respectively. The developed procedure was applied for determination of these trace elements in produced formation water from offshore platforms in the Brazilian Northeast.
