“…Sri Lanka Standards (SLS)(1985) for water quality parameters specified for inland surface waters for use as raw water for public water supplies include pH, dissolved oxygen, BOD 5 and chromium levels. The pH, dissolved oxygen and total chromium levels of the downstream water of the Dandugan Oya (raw water intake area for public water supply) were within the SLS specified limits.…”

“…Moreover, this test system provides information to evaluate the genotoxic mechanisms of an agent (clastogenic and/or aneugenic effects) on the genetic material (Leme & Marin-Morales, 2009). Recently, cytotoxic and genotoxic effects on A. cepa have been reported following exposure to a number of pollutants including heavy metals (Barbosa et al, 2010;Hemachandra & Pathiratne, 2015), pesticides (Liman et al, 2011;Türkoğlu, 2012), complex mixtures such as industrial and municipal wastes (Chandra et al, 2005;Radic et al, 2010;Siddiqui et al, 2011) and emerging contaminants (Herrero et al, 2012).…”

Industrial waste may contain complex chemical mixtures with potential cytotoxic and genotoxic effects. The Dandugan Oya, a water canal located in the Western Province of Sri Lanka receives industrial waste from multiple sources. In the present study potential toxicity of selected industrial wastewaters reaching the Dandugan Oya, and the downstream water was assessed using a plant based bioassay with onion (Allium cepa L. var. ascalonicum) as the test organism. Of the physico-chemical characteristics tested, temperature, pH, biochemical oxygen demand, chemical oxygen demand, cadmium and chromium levels of the wastewaters collected during three sampling occasions in the year 2012 were within the national tolerance limits specified for the discharge of industrial effluents into inland surface waters. The exposure of A. cepa bulbs to wastewater and downstream water from the Dandugan Oya resulted in the reduction of root growth (24 -62 %) and mitosis (31 -55 %), induction of micronuclei (up to 0.6 %), nuclear abnormalities (3 -14 folds) and chromosomal aberrations (3 -21 folds) in the root tip meristematic cells compared to those exposed to the control and the upstream water, indicating cytotoxic and genotoxic effects. No significant difference between the control and the upstream water was found in relation to the measured biological effects (p > 0.05). The present study revealed that the tested wastewaters contained cyto-genotoxic contaminants and, the inherent dilution/detoxification capacity of Dandugan Oya during the study period was not adequate to eliminate the toxic effects in the downstream water. In addition to the conventional physico-chemical analyses, inclusion of suitable bioassays as additional assessments in water quality monitoring programmes could alert cyto-genotoxic impacts in wastewater receiving inland surface waters.

“…This test has been widely used in toxicity, mutagenicity and genotoxicity studies for diverse hazardous contaminants such as pesticides, dyes, food preservatives, and hydrocarbons (Fatima and Ahmad 2006;Mitteregger et al 2007;Feretti et al 2007;Türkoglu 2007;Leme and Marin-Morales 2008;Mustafa and Arikan 2008;Ashraf and Husain 2010), and is one of the most established test systems used to determine toxicity in several laboratories (Rank et al 2002;Chandra et al 2005;Yıldız et al 2009). This assay demonstrates alterations in all phases of the cell cycle, which are considered evidence for mutagenic effects induced by clastogenic or aneugenic agents (classified according to the type of alteration induced) (Vidakovié-cifrek et al 2002).…”

Mutagenicity of two herbicides widely used on soybean crops by the Allium cepa test

et al. 2015

This study evaluated the mutagenic effects of two herbicides: Clorimurom Nortox Ò and Imazaquim Ultra Nortox Ò widely used on soybean crops in Brazil. As a test system, Allium cepa assay was used, which analyzes the frequency of micronuclei (MN), chromosomal aberrations (CA) and the mitotic index (MI). Four concentrations of each herbicide (50, 75, 100 and 125 %) were tested in triplicate using distilled water (negative control) and methyl methanesulfonate (positive control) as controls. Three experimental repetitions were realized. Clorimurom Nortox Ò showed a significantly lower MI than the negative control for the concentrations of 75, 100 and 125 %, but the CA was significantly increased at all concentrations. There was no recovery for CA or MI. The 125 % concentration of Imazaquim Ultra Nortox Ò was cytotoxic and also exerted an effect on the other parameters. The concentration of 100 % showed a statistically increased MN and there was no recovery, while the 75 % concentration significantly affected CA, with recovery observed. The two herbicides showed mutagenic damage in Allium cepa cells, which implies a careful handling of these products, to minimize the risk of human and environmental contamination.

“…As plantas são consideradas ferramentas úteis na investigação da toxicidade e genotoxicidade de metais CHANDRA et al, 2005;MATSUMOTO et al, 2006;YILDIZ et al, 2009). Diversos estudos têm mostrado que os efeitos genotóxicos dos metais podem se manifestar como distúrbios no fuso mitótico e alterações na estrutura e no número cromossômico (FISKEJÖ, 1983).…”
