“…The site, Kalajharia, is an important point-source of pollutants, where, mostly the untreated waste water of some steel industries, iron foundries and electroplating industries are released and drained into the Damodar river. Due to the ineffectiveness of purification systems, waste waters may become seriously dangerous, leading to the accumulation of toxic metal ions in the receiving water bodies with potentially serious consequences on the ecosystem [18,19]. There are some of the important parameters which adversely affect the river water quality.…”

“…Vanadium is a heavy metal with increased environmental circulation, resulting from various anthropogenic activities [29][30][31] and it is of great concern due to its toxicity and accumulative behavior at specific target organs, such as the liver and kidney, inducing oxidative damage, lipid peroxidation and changes in haematological, reproductive and respiratory systems [32][33][34][35][36]. Formation of reactive oxygen species (ROS) induced by vanadium in biological systems may involve Fenton-like reactions [34], vanadate bioreduction mediated by reduced glutathione (GSH), flavoenzymes or nicotinamide adenine dinucleotide, reduced form (NADH), and nicotinamide adenine dinucleotide phosphate, reduced form, (NADPH) oxidases [37][38][39] or interaction with mitochondria [14].…”

Vanadium biological studies often disregarded the formation of decameric vanadate species known to interact, in vitro, with high-affinity with many proteins such as myosin and sarcoplasmic reticulum calcium pump and also to inhibit these biochemical systems involved in energy transduction. Moreover, very few in vivo animal studies involving vanadium consider the contribution of decavanadate to vanadium biological effects. Recently, it has been shown that an acute exposure to decavanadate but not to other vanadate oligomers induced oxidative stress and a different fate in vanadium intracellular accumulation. Several markers of oxidative stress analyzed on hepatic and cardiac tissue were monitored after in vivo effect of an acute exposure (12, 24 h and 7 days), to a sub-lethal concentration (5 mM; 1 mg/kg) of two vanadium solutions (''metavanadate'' and ''decavanadate''). It was observed that ''decavanadate'' promote different effects than other vanadate oligomers in catalase activity, glutathione content, lipid peroxidation, mitochondrial superoxide anion production and vanadium accumulation, whereas both solutions seem to equally depress reactive oxygen species (ROS) production as well as total intracellular reducing power. Vanadium is accumulated in mitochondria in particular when ''decavanadate'' is administered. These recent findings, that are now summarized, point out the decameric vanadate species contributions to in vivo and in vitro effects induced by vanadium in biological systems.

“…High concentrations of phenol, oil and grease, and ammonia were observed in water and sediment at the point of effluent discharge due to accumulation over long period of time [2]. These toxic products are with potentially serious consequences on the receiving environment and ecosystem [3]. Treatment of refinery wastewater is normally complex, costly and involved processes to remove organic compounds and other hazardous substances.…”

The anoxic-aerobic wastewater treatment process increases wastewater treatment efficiency and decreases the aeration basin. In this study, raw data obtained from two anoxic-aerobic biological reactors (AABR) used for the treatment of different loads of petroleum refinery wastewater (PRW) were used for developing a mathematical model that could simulate the process trend. The data consists of 160 entries and was gathered over approximately 180 days from two AABR reactors that were continuously operated in parallel. Two configurations of artificial neural networks were compared and different numbers of neurons were tested for an optimum model that could represent the process behaviour under different loads. The tangent sigmoid transfer function (Tansig) at the hidden layer and a linear transfer function (Purelin) at the output layer with 9 hidden neurons were selected as the best optimum model. From the simulation model, the highest removal efficiency was observed as 96%, which was recorded for chemical oxygen demand (COD) influent concentration of 3150 mg/L. Effluent concentration below 100 mg/L was recorded for influent COD concentration, which ranged between 150 and 700 mg/L corresponding to the removal efficiency in the range of 78-88%.
