| The vanadium is a metal that presents great interest from the toxicological point of view, because of the numerous alterations that can take place in different biological systems. This work evaluated the capacity of vanadium accumulation and its correlation with genotoxic effects in root cells of Allium cepa L. The bulbs were cultivated in renovated filtered water each 24 h, at a temperature of 25 ± 0.5 ° C, in darkness and constant aeration. Treatments were carried out under the same experimental conditions, using water solutions of vanadium of 25, 50, 75 and 100 µ g/g for 0, 12, 24, 48 and 72 h. A control was carried out where metal solution was substituted by distilled water. After the treatment, the meristems were fixed with alcohol - acetic acid (3:1)... |

| The present study aims to measure the concentration of vanadium in 73 sediment samples collected along the coastal area of the Egyptian seas (Mediterranean and Red Seas). The results indicated that the mean value of vanadium in Red Sea sediments (52.61 µg/g) was higher than the mean value of the Mediterranean (40.58 µg/g) and the variation between the two means was insignificant (p = 0.241). This result could be attributed to the high petroleum activities of the Red Sea. Along the Mediterranean coast, the sector in front of Port Said area exhibited the highest mean value of vanadium (103.9 µg/g) than other sectors, which suffers from many sources of pollution. While the highest mean value along the Red Sea coast (73.20 µg/g) was found at the sector of Red... |
