“…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.

“…In this framework, the evaluation of the uncertainty associated with the quantification of micropollutants like PAHs in the environment plays an important role to give reliability to the estimate obtained for the measurand. Examples of uncertainty evaluation for organic micropollutants can be found in literature [5][6][7][8][9] and the main approach adopted is the GUM uncertainty framework, as summarized in [10, G.6.6]. The approach proposed in the GUM relies on the Law of Propagation of Uncertainty (LPU), which requires the linearization of the measurement model.…”

Se estimó la incertidumbre de medición en la concentración de una solución de ácido sulfúrico (H2SO4) estandarizada con un patrón primario de carbonato de sodio anhidro (Na2CO3), mediante un ejemplo sencillo de procesamiento de los datos experimentales obtenidos en el laboratorio. La metodología empleada se basó en la guía establecida por la EURACHEM/CITAC e incluyó las siguientes etapas: identificación de las fuentes de incertidumbre, evaluación de la incertidumbre estándar y cálculo de la incertidumbre estándar combinada e incertidumbre expandida. Las fuentes que presentaron mayor contribución a la incertidumbre fueron la reproducibilidad y la repetibilidad provenientes de la medición del volumen de H2SO4 gastado en la valoración del Na2CO3. Bajo las condiciones de estudio, la incertidumbre en la estandarización de una solución de H2SO4 de concentración 0.0127 mol/L fue ± 0.0015 mol/L.
