We investigated heavy metal concentrations of zinc (Zn), copper (Cu), chromium (Cr), and lead (Pb), their spatial distribution and enrichment factor index in surface sediments of the Gorgan Bay. Sediment Quality Guidelines were also applied to assess adverse biological effects of these metals. Heavy metals were determined by inductively coupled plasma-mass spectroscopy (ICP-MS). The results indicated mean concentrations (ppm) of heavy metals were (mean±S.D.) Pb: 11.5±4.88, Cu: 18±8.83, Zn: 42±22.15 and Cr: 32±15.19. Based on Enrichment index, the Gorgan Bay is a low-enriched to non-enriched bay. Heavy metal contents were lower than the standard limits of PEL, ERL, and ERM that reveal no threatening influence of the metals in the Bay.
我们研究了戈尔甘湾表层沉积物中锌（Zn）、铜（Cu）、铬（Cr）和铅（Pb）的重金属浓度、空间分布和富集因子指数。还应用了沉积物质量准则来评估这些金属的不良生物效应。重金属采用电感耦合等离子体质谱法（ICP-MS）测定。结果表明，重金属的平均浓度（ppm）为（平均值±S.D.）Pb：11.5±4.88，Cu：18±8.83，Zn：42±22.15，Cr：32±15.19。根据富集指数，戈尔甘湾是一个低富集到非富集湾。重金属含量低于 PEL、ERL 和 ERM 的标准限值，表明这些金属对海湾没有威胁影响。
