“…However, even after integrated treatment, coke wastewater can be still toxic for evrironment. One of the ways to assess the degree of toxicity of wastewater, apart from the determination of the physical and chemical indicators (Paździor et al 2016 ; Generowicz et al 2011 ), is the toxicity test (da Costa Filho et al 2016 ). Currently, tests based on plant bioindicators (Rorat et al 2014 ) are often recommended as an effective and affordable method of assessing the toxicity (Placek et al 2016 ) and genotoxicity of environmental samples with a sensitivity similar to tests using mammalian cells (Obidoska et al 2015 ).…”

In this paper, coke wastewater that had passed through biological and integrated membrane processes (filtration on sand bed—reverse osmosis) was chosen to assess the phytotoxicity of selected industrial wastewater with regard to the test plant—Vicia faba. An innovative research technique in vitro test was conducted in a large scale phytothrone chamber on two matrices: cotton and Murashige and Skoog Basal Medium (MSBM). The toxicity of wastewater was evaluated for samples: (1) treated in the treatment plant by biological processes, (2) filtrated through a sand bed and filtrated (3) reverse osmosis (RO) membrane. The results showed that there is a noticeable correlation between increasing concentrations of wastewater and seed germination of the test plant. Although the wastewater collected from the coke plant was treated biologically, it showed very high levels of germination inhibition (90–98% for cotton matrix and 92–100% for MSBM matrix) and strong toxic effects. The wastewater collected from the coke plant showed a significantly greater phytotoxic effect compared with those obtained from the effluent treated on a sand bed and in RO. However, wastewater, even after treatment on a sand bed (reduction of COD—39%, TN—46%, TOC—42%, TC—47%, SS—50%, 16PAHs—53%), was still toxic and germination inhibition was in the range of 24–48% for the cotton matrix and 14–54% for the MSBM matrix. The toxicity of wastewater treated in the membrane process was the lowest (reduction of COD—85%, TN—95%, TOC—85%, TC—86%, SS—98%, 16PAHs—67%). The germination inhibition was in the range of 4–10% for the cotton matrix and 2–12% for the MSBM matrix. These samples are classified as non-toxic or slightly toxic to the model plant. The present study highlights the necessity of monitoring not only the basic physical and chemical indicators (including the level of toxic substances as PAHs), but also their effect on the test organisms in wastewater samples.

“…Some industries are contaminating water bodies by toxic materials, while other are responsible for colored effluents (KANU and Achi, 2011). Beside, heavy metals, the industrial wastewater also contains a considerable amount of inorganic materials, organic compounds, salts, detergents, surfactants, dyes, food additives etc, which affect the water physico-chemical properties and toxicity to living organisms (Abbasi et al, 2016;Asadi et al, 2016;Balapure et al, 2016;Barbosa et al, 2014;Barrera-Díaz et al, 2014;Behbahani et al, 2016;Bertani et al, 2016;Bordes et al, 2015;Camacho-Muñoz et al, 2014;Carbajo et al, 2015;Chae et al, 2016;Cheballah et al, 2015;Chong et al, 2015;Chou et al, 2014;da Costa Filho et al, 2016;da Costa et al, 2012b;Expósito et al, 2016;Gatsios et al, 2015;Gatta et al, 2015;Goh et al, 2015;Hoshina and Marin-Morales, 2009;Hu et al, 2015;Jeon, 2015;Kang et al, 2016;Kuroda et al, 2015;Lee et al, 2016;Lee et al, 2015;Liu et al, 2016;Lovatel et al, 2015;Meneses-Jácome et al, 2016;Olorunfemi et al, 2011b;Pereyra et al, 2015;Polat et al, 2015;Prieto et al, 2015;Sarkar et al, 2015;Sasmaz and Yaman, 2008;…”

All sorts of pollution on the planet can be traced back to development of industries and the most important among them is water pollution. Clean technologies, management practices and regular monitoring of effluents could be helpful to minimize the contamination of watersheds. Allium cepa (A. cepa) has been recognized as a promising genetic model to detect the toxicity of industrial wastewater, contaminated soil, river water, nuclear contamination and even for those systems which are considered non toxic. A. cepa is distinguished as a low cost test, easy to handle and sensitive to both in vivo and in vitro models. It offers the detection of damages in genetic material quantitatively and the results can be generalized for other biological and ecological systems. Moreover, the pollutants can be classified on the basis of this test present in industrial effluents and their mechanism of action on genetic material. This review focuses on the studies undertaken to evaluate the toxicity of industrial wastewater, contaminated river and soils.

The role of different operational parameters related to Fenton reactions (pH, concentration of Fe and HO, and reaction time) and of Cl and SO was investigated in the degradation of the azo dye Direct Red 81, expressed in terms of its decolorization. The factorial design and Pareto's charts showed that only Fe concentration and pH influence the decolorization under the conditions evaluated. So, only these parameters were optimized using the response surface model. Under the best experimental conditions (initial pH 2.5, 11 mg L Fe, 78 mg L HO, and 20 min of reaction), 94 % of decolorization was achieved. However, even under the these conditions, but in the presence of Cl and SO , a striking loss of efficiency was observed as the concentration of these ions was increased, due the formation of chloride- and sulfate-iron complexes and less reactive inorganic radicals (Cl and SO). The results show that the presence of Cl is more deleterious, since sulfate-iron complexes are more reactive towards HO, and the SO turns out to favor the degradation. On the other hand, the negative effect of Cl can be compensated by increasing the chloride concentration up to 300 mmol L. In addition, although a high degradation level has been obtained by monitoring the dye absorbance and by HPLC-UV, a low mineralization occurred, being generated degradation products of higher ecotoxicity to Vibrio fischeri, showing the need of subsequent studies to identify these compounds as well as the application of additional treatments aiming the complete mineralization of the dye.
