BACKGROUND

Persian Gulf is an exposed and stressed area as a result of oil pollution and other fossil fuels containing PAHs. The susceptibility of using mudskippers to monitor marine pollution, like PAHs, points to the fact that mudskippers are able to accumulate and record the PAHs presented in the coastal environments.

METHODS

Polycyclic aromatic hydrocarbons (PAHs) were examined in the coastal waters, the sediments and biota (i.e., Boleophthalmus dussumieri) along the coast of the Persian Gulf. PAHs concentrations were measured with HPLC method.

RESULTS

Total PAH concentrations in the sea water, the sediments, the liver and the gill tissues ranged between 0.80-18.34 μg/l, 113.50-3384.34 ng g-1 (d w), 3.99-46.64 ng g-1 (d w) and 3.11-17.76 ng g-1 (d w), respectively. PAHs distribution patterns in the sediment and the liver tissue samples were dominated by three-and four-ring structures whereas two-and three-rings were dominated in the water and the gill.

CONCLUSIONS

This finding revealed a negative eco-risk effects occasionally occur in this area. The higher presence of low condensate ring structures reflected a predominant origin of petrogenic and some cases of pyrolitic sources.

背景

波斯湾由于石油污染和其他含多环芳烃的化石燃料而成为一个暴露和压力大的地区。弹涂鱼能够监测海洋污染（如多环芳烃），这表明弹涂鱼能够积累和记录沿海环境中存在的多环芳烃。

方法

在波斯湾沿岸地区的沿海水域、沉积物和生物群（即大弹涂鱼）中检查了多环芳烃（PAHs）。采用高效液相色谱法测定多环芳烃浓度。

结果

海水中、沉积物中、肝脏组织中和鳃组织中的总多环芳烃浓度分别在 0.80-18.34μg/l、113.50-3384.34ng/g（dw）、3.99-46.64ng/g（dw）和 3.11-17.76ng/g（dw）之间。沉积物和肝脏组织样本中的多环芳烃分布模式以三环和四环结构为主，而水和鳃中的二环和三环结构为主。
