“…The effects of spices were based on microscopic and macroscopic evaluations which include abnormalities like stickiness, vagrant type, sticky chromosome, laggard binucleate etc. The present study provides evidence that the uncooked spice (curry, thyme, suya and pepper soup spice) and the cooked spice (curry, thyme and pepper soup spice) inhibits root growth and caused retardation which is in agreement to the findings of Odeigah et al (1997).…”

“…This conforms to the finding of Bakare et al (2003), who reported reduction in mitotic indices obtained in the treated root A. cepa with increase in concentration of neem extract. With increasing concentration and increasing toxicity, there was an inhibitory effect on cell division (Odeigah et al, 1997).…”

Spices are commonly used in modern culture for varieties of delicacies; some spices are eaten raw, while others are cooked with the meal. However, as important as spices are in our everyday life, the methods through which some of them are being produced are questionable and as such may pose a significant health risk to the society. This study was therefore designed to investigate the genotoxicity of four well known spices (thyme, curry, suya and pepper soup) using Allium cepaassay, as well as to evaluate their nutrient value, microbial load and heavy metal contents. The spice caused a reduction in the mean root length in onion bulbs exposed to the treatment of both the cooked and uncooked forms of the spices. Analysis of variance showed that there was no significant difference (p>0.05) in the mean root length and mitotic indices of A. cepa exposed to different concentrations (1%, 5%, 25%, 50% and 100%) of the spices. The mitotic index was inversely proportional to the mitotic inhibition. The spices induced chromosomal aberrations such as vagrant, stick anaphase and telophase, bridges etc in exposed Allium cepacompared to control. Microbial evaluation of the spices showed that the suya and pepper soup spice had the most significant microbial load above the standardized permissible level. Proximate analysis of the spices showed that suya spice had the highest fat (14.85%) and protein (37.33%) content, while thyme had the highest moisture (12.45%) and crude fibre (18.70%) content. Heavy metal analysis showed that lead (Pb) was absent from of all the spices evaluated, while all the spice had cadmium contents above the permissible limit. However only suya spice was found to contain nickel (Ni); content above the permissible limit. The findings of this study therefore showed that the uncooked/ unprocessed spices are less safe than the cooked/ processed spices.

“…It was not observed any anomalies in 48 and 96 h at 30 g/L. C-metaphase, a possibly reversible effect, might occur due to disturbed microtubules by Lg-ext and could be induced aneuploidies (Fiskesjö, 1988;Shahin & El-Amodi, 1991;Odeigah et al, 1997). Polyploidy cells can occur due to the lack of fragmoplast that prevents the formation of the daughter cells (Vidakovivé-Cifrek et al, 2002;Fernandes et al, 2007).…”

Genotoxic and mutagenic effects of aqueous extract from aerial parts Linaria genistifolia (L.) Mill. subsp. genistifolia, Plantaginaceae (Lg-ext) were investigated by using both Allium cepa root meristematic cells and bacterial reverse mutation assay in Salmonella typhimurium TA98 and TA100 with or without metabolic activation system (S9), respectively. In Allium root growth inhibition test, EC50 value was determined approximately 15 g/L and 0.5xEC50, EC50 and 2xEC50 concentrations of Lg-ext were introduced to onion tuber roots and distilled water and methyl methane sulfonate (MMS, 10 ppm) used as a negative and positive control, respectively. The characteristic effect caused by tested preparations was an increase of mitotic index (MI) in 7.5 g/L and 15 g/L (except 24 and 96 h) and simultaneous decrease of MI in 30 g/L and in MMS. While stickiness, bridges, chromosome laggards and disturbed anaphase-telophase were observed in anaphase-telophase cells, c-metaphase, pro-metaphase, polyploidy and binuclear cells were observed in other cells. Lg-ext was not found to be mutagenic on S. typhimurium TA 98 and TA100 with or without S9. The results were also analyzed statistically by using SPSS for Windows, and Duncan's multiple range tests were performed respectively. These results indicate that Lg-ext exhibits genotoxic activity in A. cepa root meristematic cells but not mutagenic activity in Ames test system.

Abstract. Oil and gas exploration and production are two of the activities that potentially cause pollution and environmental damage. The largest waste generated from this activity is produced water. Produced water contains hazardous pollutants of both organic and inorganic materials, so that the produced water of oil and gas production cannot be discharged directly to the environment. Uncontrolled discharge can lead to the environmental damage, killing the life of water and plants. The produced water needs to be handled and fulfill the quality standards before being discharged to the environment. Several studies to reduce the contaminants in the produced water were conducted by researchers. Among them were gravity based separation -flotation, separation technique based on filtration, and biological process treatment. Therefore, some of these methods can be used as an alternative waste handling of produced water.
