测定了旧金山湾南部潮间带盐沼中溶解态和颗粒态Cd、Cd和Cd。金属的相分布(溶解与颗粒)与它们在计算机模拟的海盐基质中的计算形态是一致的。微量金属在微观层的富集度与样点的物理事件相对应。河口和沼泽系统之间的Cd、Cu和Pd的对流交换主要是以散装悬浮颗粒金属的输送为主，从沼泽到海湾的明显净出口。
Dissolved and particulate Cd, Cu, and Pb were measured in bulk solution and surface microlayer samples from an intertidal salt marsh in south San Francisco Bay. The phase distribution (dissolved vs. particulate) of metals was consistent with their calculated speciation in computer-simulated sea-salt matrices. Trace metal enrichment at the microlayer corresponded with physical events at the sample site. Advective exchange of Cd, Cu, and Pb between the estuary and marsh systems was dominated by transport of bulk suspended particulate metals, with an apparent net export from the marsh to the bay.
