摘要

这项研究的目的是测量沙特阿拉伯西南部贾赞省一家污水处理厂向海水排放砷污染的后果。砷释放对生态系统的影响在于海洋植物对砷的吸附。为此，在距离污水处理厂七公里处采集了样本。藻类样本马尾藻（Sargassum sp.）、浒苔（Cladophora sp.）和海草：在硝酸中消化后，根据 EPA 方法用 ICP-AES 检测砷含量。结果表明，藻类比海草吸收砷的效率更高。此外，污水处理厂并不是唯一的砷污染源，船只和船舶也在向生态系统中添加更多的砷。

Comparison of arsenic adsorption efficiency between macroalgae and seagrass on the shorelines of Jazan Province, Saudi Arabia

The aim of this study was to measure consequences of the arsenic pollution released from a sewage treatment plant into the seawater in Jazan province in the southwest of Saudi Arabia. The impact of the release of arsenic on the ecosystem is the adsorption of arsenic by sea plants. To do so, samples were collected alongside a distance of seven kilometers from the treatment plant. The algae samples: Sargassum sp., Cladophora sp., and seagrasses: Halodule uninervis and Cymodocea rotunda were digested in nitric acid, and the assays of arsenic levels were taken by ICP-AES according to EPA methods. The results showed that algae are more efficient than seagrass with absorbing arsenic. Also, the treatment plant was not the only source of arsenic contamination, as ships and boats were adding more arsenic to the ecosystem.
