In the present study to evaluate ballast water impacts on coastal areas, samples were taken from commercial ships entering Bushehr port along the Persian Gulf. Standard methods were used for analyses of total and fecal coliforms, Pseudomonas, heterotrophic plate count (HPC), alkalinity, and hardness. Other parameters such as TOC, salinity, EC and TDS were also determined. The levels of TDS, EC, alkalinity, total hardness, salinity and TOC ranged from 3790-14510 mg/L, 5690-21760 mu S/cm, 104-191 mg/L CaCO3, 1160-8940 mg/L CaCO3 , 33.2-44.98 g/L and 1.9-5.7 mg/L respectively. Twenty-four, thirteen and four samples from 34 collected samples were positive in the case of total coliforms, fecal coliforms and E. coli respectively. All samples contained Pseudomonas aeruginosa and HPC. Our results showed that ballast water has the potential to change bacteria communities and also can be pathogenic for humans and coral reefs where ships discharge their ballast water.
