【摘要】 本文通过现场调查,利用ICP-MS分析获得罗源湾水体溶解和悬浮态重金属浓度,湾顶部分站位Pb浓度超过Ⅱ类海水水质标准(最高7.22μg/L)。基于FVCOM水动力模式,利用重金属输运模型进行Pb浓度数值模拟,数值模拟结果与现场监测结果吻合良好,湾顶冶金工业聚集区附近的水体中Pb浓度较大,而水动力条件优良的湾口区域Pb浓度较小,上述结果表明罗源湾内重金属浓度与周边临港工业发展、湾内水动力条件具有较明显的相关性。更多还原

【Abstract】 Luoyuan Bay is an important natural deep water port address of Fujian Province. Recent years,as the facingport industries quickly developing,the sea water quality of Luoyuan Bay falls into decline,especially the heavy metal concentration change needs to be focused on. In this paper,ICP-MS was used to analyse the site monitor samples of Luoyuan Bay,the concentration of some bay roof region is more than class Ⅱof the sea water quality standard( up to 7. 22 μg / L). Based on FVCOM numerically simulates the concentration filed of heavy metal( Pb),the result of numerical simulation matches the measured data well. This fact shows the relevance of heavy metals concentration with the neighboring port industrial development and hydrodynamic conditions. The concentration of Pb near metallurgical industry clusters district which located in bay roof region is much bigger than the bay mouth region where has good hydrodynamic conditions.更多还原
