Determination of Heavy Metals Concentrations in Different Depths in Persian Gulf (Bandar Abbas Region) in Warm and Cold Seasons

Heavy metals removal is one of the most important environmental considerations in aquatic areas which has been the center of attention globally these days. Concentrations of such pollutants in Persian Gulf as a significant location in the West Asia where a lot of transportation is done daily was studied in this research and the amount of Zn, Cu, Pb, Fe and Mn were measured in Summer and Winter in depth of 3,10 and 15 meters in Bandar Abbas station. Based on the accurate measurements and analysis it was determined that the iron in sediments was more than other pollutants in cold seasons and Mn had the minimum value of contamination in 3 and 10 meter depth and in the 15 meter depth, Pb had the most contamination with concentration of 247 mg/kg and Mn had the least one, 48 mg/kg. Overall it should be mentioned that Mn as a heavy metal with concentration of 47.63 mg/kg represented the least role of pollution in cold seasons. In comparison, in warm seasons Fe polluted the aquatic area more than any other ones and Zn had the least portion with respect of 233.9 mg/kg and 27 mg/kg in all the 3 mentioned depths.
