In this study, the amount of heavy metals such as Ni, Cd, Pb and Cu and some physiochemical factors including pH, temperature and total organic carbon (TOC) in the ballast water of the ships entering the Bushehr Port were measured for two years (cold and hot seasons) before and after the ballast water convention was enforced. The mean concentrations of Ni, Cd, Pb and Cu, before and after implementation of the convention were 46.55, 3.93, 5.36, 58.83 and 26.41, 2.12, 2.59, 23.54 ppb. It became clear that the concentrations of heavy metals after the implementation of the convention was lower in comparison and there was a significant difference (p < .05). It seems that continuous monitoring of the quality of the ballast water and determination of locations free of pollution and contamination in the Persian Gulf are necessary for ships that intend to exchange their ballast water in this Gulf.
在本研究中，测量了在《压载水公约》生效前后两年（寒、热两季）进入布什尔港的船舶压载水中镍、镉、铅和铜等重金属的含量以及包括 pH 值、温度和总有机碳（TOC）在内的一些理化因素。在实施该公约之前和之后，镍、镉、铅和铜的平均浓度分别为 46.55、3.93、5.36 和 58.83 及 26.41、2.12、2.59 和 23.54 ppb。结果表明，实施该公约后重金属浓度降低，且存在显著差异（p <.05）。对于计划在该海湾交换压载水的船舶，似乎需要对压载水质量进行持续监测，并确定波斯湾无污染和污染的地点。
