T: This study evaluated water samples from Asa River in Kwara state, Nigeria, for cytogenotoxicity at 25.0 %, 50.0 %, 100.0 % following the Allium cepa assay. Onions were grown in the water samples for microscopic and macroscopic screenings. Heavy metals and volatile organic pollutants in the water were elucidated using AAS and GCMS techniques. The Water samples except the sample ‘C’ induced higher mitotic index (MI) than the negative control. Root growth was significantly promoted at 25.0 %, and significantly reduced at 50.0 % and 100.0 % of the sample ‘C’ and 100.0 % of the sample ‘A’. Water sample ‘A’ (100.0%) induced highest percentage chromosomal aberrations (CA) while the water samples ‘B’ and ‘C’ induced higher percentage CA than the negative control. Cadmium was detected at a concentration higher than its permissible limit in drinking water. Poly aromatic hydrocarbons, Aromatic amines, Acridine dye, Phenolic and Polychlorinated compounds were detected in the water sample. The observed proliferative, inhibitory, cytotoxic and genotoxic effects of the water samples on A. cepa cells suggest that Asa river was polluted, having potential to adversely affect humans, animals and plants utilizing it along its course.

Abstract Improper disposal of wastes as an environmental problem is common in African and other developing countries of the world, and it raises concerns due to its potential threats to the life of organisms in both terrestrial and aquatic ecosystems. In this study, Asa River in Ilorin, Nigeria was evaluated for cytogenotoxicity at 25.0 %, 50.0 %, 100.0 % following the Allium cepa assay. Water samples were collected from three points tagged A, B, C, and each point was 500 m apart from each other. The water samples were used to grow A . cepa for microscopic and macroscopic toxicities screenings. Heavy metals and volatile organic pollutants in the water were elucidated following the Atomic Absorption Spectroscopy and Gas Chromatography-Mass Spectroscopy. The Water samples induced higher mitotic index values, except the sample C which induced smaller mitotic index value than the negative control. Root growth in the exposed A . cepa was significantly promoted at 25.0 % of the water samples, while significant reduction was obtained at 50.0 % and 100.0 % of the sample C, and 100.0 % of the sample A. The absolute water sample A induced highest percentage chromosomal aberrations, as the water samples B and C induced higher percentage chromosomal aberration than the negative control. Cadmium was detected at a concentration higher than its permissible limit in drinking water unlike Zinc, Iron, Manganase. Poly aromatic hydrocarbons, Aromatic amines, Acridine dye, Phenolic and Polychlorinated compounds were detected in the water sample. These pollutants may be responsible for the observed proliferative, inhibitory, cytotoxic and genotoxic effects of the water samples on A . cepa cells. Our results suggest that Asa River is polluted, having potential to inflict different adverse effects on human, animals and plants utilizing it along its course.

Tulbaghia violacea (wild garlic) is commonly used in traditional medicine for the treatment of various ailments including fungal infections, gastrointestinal ailments, asthma, fever, colds and pulmonary tuberculosis. We assessed the potential genotoxic effects of water extracts from the leaves, stems and roots of T. violacea using the Allium cepa assay. Extracts at concentrations of 100, 250, 500 and 1000 μg/mL were tested on root meristems of A. cepa. Ethidium bromide was used as a positive control whereas distilled water acted as a negative control. The results reveal that as the concentrations of the water extracts of T. violacea increased, the mitotic indices decreased. Similarly, the percentage of chromosomal aberrations was dependent on the concentration as well as on which part of the plant was used. The six most common chromosome aberrations included laggard chromosomes, chromosome bridges, c-mitosis, sticky chromosomes, formation of binuclei and formation of trinuclei. The presence of micronucleated cells at interphase also increased as the concentration of the water extracts increased. The results confirm that water extracts of T. violacea exert significant genotoxic effects at higher concentrations, with the stem extracts being more toxic than the leaf and root extracts at similar concentrations. Significance: • Water extracts of T. violacea – a plant commonly used in traditional medicine – were found to have significant genotoxic effects at higher concentrations.

Abstract Clopyralid is a one of the synthetic pyridine-carboxylate auxin herbicides and used to control perennial and annual broadleaf weeds in wheat, sugar beets and canola etc. In this study, dose dependent cytotoxicity and genotoxicity of clopyralid at different concentrations (25, 50, and 100 µg/mL) on the Allium cepa roots were evaluated at macroscopic (root growth) and microscopic levels (Mitotic index (MI), chromosome aberrations (CAs) in ana-telophase cells and DNA damage) using root growth inhibition, Allium ana-telophase and comet tests. The percentage root growth inhibition and concentration reducing root growth by 50% (EC50) of clopyralid in relation to the negative control were determined by using various concentrations of clopyralid (6.25–1000 µg/L). The 96 h EC50 of clopyralid was recorded as 50 µg/L. The gradual decrease in root growth and the MI reveals the cytotoxic effects of clopyralid. All the tested concentrations of clopyralid induced total CAs (polyploidy, stickiness, anaphase bridges, chromosome laggards, and disturbed ana-telophase) and DNA damage dose and time dependently. This study confirmed cytotoxic and genotoxic effects of clopyralid on non-target organism.

AbstractPlantago is the most important genus of Plantaginaceae family and is used in traditional medicine around the world for different purposes. Plantago coronopus L., Plantago major L., Plantago media L. and Plantago lanceolata L. are most commonly used species of Plantago in traditional medicine in Turkey. The main goal of this study was to investigate the eventual anti-mitotic and anti-genotoxic effects of P. lanceolata L. leaf aqueous extracts (15 g/L and 30 g/L) on Allium cepa L. root tip meristem cells which were treated with 0.7% hydrogen peroxide. For this purpose, two different experiments were performed under the same conditions. In the first experiment, Allium cepa onion bulbs were treated with 0.7% H2O2 for 1 h. After the H2O2 treatment, the onion bulbs were treated with two different concentrations (15 g/L and 30 g/L) of P. lanceolata extracts for 24 h. In the second experiment, A. cepa onion bulbs were treated with two different extract concentrations (15 g/L and 30 g/L) for 24 h and then with 0.7% H2O2 for 1 h. The test concentrations were determined according to doses which are recommended in alternative medicinal usage by people. As positive and negative control 0.7% H2O2 and tap water was used, respectively. As a result, it was determined that aqueous extracts reduced mitotic index and chromosome aberrations in treatment groups in comparison with controls. These results showed that P. lanceolata aqueous extracts have anti-mitotic and anti-genotoxic effects.

This study investigated the protective effective of Sida acuta leaf extracts against the genotoxic effect of lead nitrate, a toxic heavy metal that easily permeate the ecosystem. The genotoxic and anti-genotoxic effects of the aqueous extract of S. acuta on onion cells (Allium cepa L.) was evaluated using the Allium cepa L. assay. Onion bulbs were exposed to 0.25 – 2.5 mg.mL-1 concentrations of the plant extract for analyses of induction of cytogenetic damage. There was observeda concentration-dependent decrease in mitotic index of the A. cepa roots cells compared to the negative control. Lead nitrate significantly induced chromosomal aberration in A. cepa root cells. This effect, however, was significantly ameliorated by the S. acuta leaf extract. This effect was demonstrated by the lower frequency of chromosome aberrations in lead nitrate treated root cells after exposure to the extract. Furthermore, the extract restricted the extent of lead-induced cytological aberrations in A. cepa. The findings in this study suggested the mitodepressive, antiproliferative and anti-genotoxic potentials of the extract.

Anthropic activities as well as land use and occupation are closely linked to water and soil quality. An alternative to assess their influence on water quality in water bodies is through biomonitoring using Allium cepa as a bioindicator organism. This technique allows the detection of cytogenetic abnormalities in Allium cepa root meristematic cells after contact with analyzed water samples. Thus, we evaluated the genotoxic potential of water samples from the Rio das Antas (Antas River) along the urban perimeter of the city of Irati, Paraná, Brazil.  With the aid of GeoEye Satellite high-resolution fused orbital images, we searched for possible relationships between the use and occupation of land around this river. Biomonitoring was performed at three different sampling points. Statistical equality between the negative control and Point 1 and between Points 2 and 3 was obtained using Fisher's test and a Principal Coordinate Analysis (PCoA). The former presented a low frequency of abnormalities chromosomes and the latter presented larger averages. In addition, Point 1 had strong influence of tree vegetation.  Points 2 and 3, demonstrated a strong influence of urbanized area, with significant degradation of permanent preservation areas (áreas de preservação permanente – (APP). The results showed remarkable anthropogenic interference to the ecosystem. Furthermore, this indicates importance of an APP watercourses functioning to preserve the quality of the water resources.
