Distribution of vanadium in bottom sediments from the marine coastal area of the Egyptian seas
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 Sea proper. ANOVA analysis showed that the differences in vanadium levels at the Mediterranean sectors were mostly significant at p < 0.05. While for Red Sea sectors, the differences were insignificant except that between Red Sea proper and Aqaba Gulf. Station M10 (at Mediterranean – Port Said sector) and station S2 (at Red Sea – Suez Bay) recorded values of vanadium higher than the typical concentration in sediments (20 – 150 µg/g). These two stations receive huge amount of wastes as industrial and agricultural effluents, sewage discharge, in addition to shipping activities, fishing ports and ship waiting areas; in particular, station S2 (Suez Bay) is characterized by petroleum activities.
