Risk Evaluation of Industrial Wastewater on Plants Using Onion (allium Cepa L.) Chromosome Aberration Assay
Rapid strides in industrialization coupled with incomplete sewage treatment system have led to indiscriminate discharge of potentially mutagenic wastewater into agricultural lands and water bodies. The response of Onion plant genetic material to the presence of potential cytotoxic and genotoxic substances in the environment was used to evaluate the toxicity of chemical effluent collected from a...
متن کاملAllium cepa Root Chromosomal Aberration Assay: An Efficient Test System for Evaluating Genotoxicity of Agricultural Soil
Agricultural soils are increasingly becoming sinks for wide number of hazardous contaminants which ultimately result in pollution. Plant bioassays, because of their sensitivity and affordability, have been recommended as first-tier assays which enable the detection of contaminants. The present study involves genotoxicity of four soil samples collected from different regions of Amritsar employin...
متن کاملGenotoxicity Screening of Industrial Effluents using Onion bulbs (Allium cepa L.)
The potential cytotoxicity and genotoxicity of three industrial wastewaters (brewery, rubber and bottling) in Benin metropolis using the Allium cepa test were investigated. A series of five small onion bulbs were cultivated in 0.01, 0.1, 1, and 10% of the wastewaters (v/v) and after 48 hours, one root tip from each bulb was harvested and processed for cytological studies by the aceto-orcein squ...
متن کاملGenotoxicity of Euphorbia hirta: an Allium cepa assay.
The potential genotoxic effects of methanolic extracts of Euphorbia hirta which is commonly used in traditional medicine to treat a variety of diseased conditions including asthma, coughs, diarrhea and dysentery was investigated using Allium cepa assay. The extracts of 125, 250, 500 and 1,000 µg/mL were tested on root meristems of A. cepa. Ethylmethanesulfonate was used as positive control and ...
متن کاملGenotoxicity of Atrazine, Avenoxan, Diuron and Quizalofop-P-ethyl Herbicides using the Allium cepa Root Chromosomal Aberration Assay
Cytogenetic effects of different herbicides viz. Atrazine, Avenoxan, Diuron and Quizalofop-P-ethyl (QPE), were evaluated in the root tip meristem cells of Allium cepa. In the Allium root growth test, the effective concentration (EC50) value was determined as approximately 0.5 ppm in the case of Atrazine and Avenoxan and 1.0 ppm in the case of Diuron and QPE herbicides with a control for each co...
