Evaluation of Cu, Zn, Fe, Mn and Pb Concentrations at Three Depths at Bandar Lengeh Port in Persian Gulf in Two Seasons

— Among many pollutants in aquatic areas such as seas, oceans, lakes and other water based areas even wastewaters, heavy metals removal is one of the most important environmental considerations which has globally been the center of attention in the current century. Concentrations of such pollutants in Persian Gulf as a significant aquatic 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 Lengeh station as one of the stations for further protection. Based on the accurate measurements and analysis it was determined that Fe in sediments was more than other pollutants in both cold and warm seasons and in all the 3 studied depths while in cold seasons Mn had the minimum value of contamination in 3 and 10 meter depth (41.19±0.06 mg/kg and 47.32±0.32 respectively) and in the 15 meter depth, Cu had the least contamination with concentration of 70.06±0.06 mg/kg. In comparison, in warm season the minimum contamination belonged to Zn in all the 3 studied depths
