“…Following 5 days of treatment, the mean root lengths were 3.9, 6.6, 9.0, 9.1, and 11.8 cm when grown in 100%, 75%, 50%, 25%, and 0%, respectively (Table 4). Inhibition of A. cepa root growth and length observed in the present study following treatment with pulp and paper mill effluents was in agreement with the previous studies [12,38].…”

Pulp and paper mill effluent induced phytotoxicity and genotoxicity in mung bean (Vigna radiata L.) and root tip cells of onion (Allium cepa L.) were investigated. Physicochemical characteristics such as electrical conductivity (EC), biological oxygen demand (BOD 5 ), chemical oxygen demand (COD), and total phenols of the pulp and paper mill effluent were beyond the permissible limit specified for the discharge of effluent in inland water bodies. Compared to control plants, seedling exposed to 100% effluent concentration showed a reduction in root and shoot length and biomass by 65%, 67%, and 84%, respectively, after 5 days of treatment. A. cepa root tip cells exposed to effluent concentrations ranging from 25 to 100% v/v showed a significant decrease in mitotic index (MI) from 32 to 11% with respect to control root tip cells (69%) indicating effluent induced cytotoxicity. Further, the effluent induced DNA damage as evidenced by the presence of various chromosomal aberrations like stickiness, chromosome loss, anaphase bridge, c-mitosis, tripolar anaphase, vagrant chromosome, and telophase bridge and micronucleated and binucleated cell in A. cepa. Findings of the present study indicate that pulp and paper mill effluents may act as genotoxic and phytotoxic agents in plant model system.

“…V. radiata is one of the important test species used to evaluate the phytotoxicity of environmental pollutants [9,10]. A. cepa (2 = 16) is used for chemical screening and in situ monitoring of the genotoxicity of heavy metals, effluents, and herbicides [11][12][13][14].…”

“…For this purpose, following four microscopic genetic endpoints are reported for the assessment of toxicity in A. cepa, namely, mitotic index (MI), chromosonal aberrations (CA), nuclear aberrations (NA) and micronuclei (MN) (Leme and Marin-Morales, 2009). Additionally, some researchers have also used macroscopic characteristics such as number of root, length of root and root physical appearance for the indication of toxicity (Bianchi et al, 2011;Fazili and Ahmad, 2014;Lerda et al, 2010;Olorunfemi et al, 2011b;Olorunfemi et al, 2015b;Radić et al, 2010;Roa et al, 2012;Siddiqui et al, 2011;TORRES et al, 2014). These end points are used for the evaluation of cytotoxicity, genotoxicity and mutagenicity of the pollutant.…”

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 Allium cepa assay has been widely used for evaluation of cytotoxic and genotoxic activity of various compounds (RIBEIRO et al, 2016;DEL CAMPO et al, 2005;BARBÉRIO et al, 2009;ROA et al, 2012;FRESCURA et al, 2013), including medicinal herbs (BAGATINI et al, 2007). It has been validated by an international collaborative study by the United Nations Environmental Program (UNEP), World Health Organization (WHO) and US Environmental Protection Agency (USEPA) as an efficient test for genetic monitoring (BADMUS et al, 2013).…”

ABSTRACT:The latex obtained from Jatropha curcas (physic nut) is used in traditional medicine to treat a variety of disturbs, including burns, hemorrhoids, ringworm and ulcers. Phytochemical analyses have shown that J. curcas latex contains natural compounds with therapeutic potential. In this study, the toxicity, cytotoxicity and genotoxicity effects of J. curcas latex on the root cells of Allium cepa were examined. Onion seeds and bulbs were exposed to seven different concentrations of latex and then the roots were submitted to macro and microscopic analyses. Water and sodium azide were used as negative and positive controls, respectively. The analysis of root growth showed that J. curcas crude latex or 50% diluted is highly toxic. Cytogenetic results showed that the mitotic index of the onion roots submitted to latex treatment decreased significantly compared to the negative control, which suggests that the latex is cytotoxic. High incidence of chromosome aberrations in the cells treated with J. curcas latex was observed too, indicating that the latex also presents genotoxic effect. The analyses presented in this report suggest the toxic, cytotoxic and genotoxic effects of J. curcas latex. Then, the indiscriminate use of J. curcas latex in folk medicine could bring risk to human health.
