Mercury has been measured by using Cold Vapor-Atomic Absorption Spectrophotometry in coastal sediments of the Persian Gulf (Bandar Abbas region). The mean concentration of the six stations followed a decreasing order of S6 (3.95) > S1 (3.75) > S4 (3.55) > S5 (3.33) > S2 (2.72) > S3 (2.17), and the mean concentration ± standard error was calculated to be 3.24 ± 0.28 (μgg dry weight) for the heavy element Mercury in the sediments. The statistical investigation indicated that the concentration means of the Mercury existing in transects sediments are meaningfully different from each other (p < 0.05). To properly assess the availability and mobility of elements, Enrichment Factor (EF), Geoaccumulation index (Igeo), Contamination factor (C) and Toxicity Risk Index (TRI) were provided. The results show that the pollution caused by Mercury in sediments is highly polluted and the source of the presence of Mercury in the region is human-made.
采用冷蒸气-原子吸收分光光度法对波斯湾（阿巴斯港地区）沿海沉积物中的汞进行了测量。六个站位的平均浓度依次为 S6（3.95）> S1（3.75）> S4（3.55）> S5（3.33）> S2（2.72）> S3（2.17），重金属汞在沉积物中的平均浓度±标准误差计算为 3.24±0.28（μgg 干重）。统计调查表明，各断面沉积物中汞的浓度均值差异有统计学意义（p<0.05）。为了正确评估元素的有效性和迁移性，提供了富集因子（EF）、地积累指数（Igeo）、污染因子（C）和毒性风险指数（TRI）。结果表明，沉积物中汞造成的污染属于高度污染，该地区汞的存在来源是人为的。
