以镍作自然参比元素 ,用元素相关图法分析了南海东北部红海湾表层沉积物中铅、锌含量的分布和污染状况。结果表明 :红海湾已经受到人为来源的铅、锌影响 ,但其影响的范围和强度目前尚小 ,仅在湾顶河口浅水区有轻微污染 ,湾中部养殖区、南部自然水域和湾口礁滩护养增殖区尚未受到人为来源的铅、锌影响。元素相关图提供了有关污染区域、污染点、污染物和污染强度等的总信息
Using nickel as a natural reference element, the distribution and pollution status of lead and zinc in the surface sediments of the Red Bay in the northeastern South China Sea were analyzed by element correlation diagram. The results show that the Red Bay has been affected by the lead and zinc sources, but the scope and intensity of its impact is still small. It is only slightly contaminated in the shallow waters of the Bayou Estuary. The aquaculture area in the central Gulf, the natural waters in the south and the reefs in the bayou The proliferative zone has not been affected by anthropogenic sources of lead and zinc. The elemental correlation chart provides general information about the area of contamination, points of pollution, pollutants and intensity of contamination
