摘要： 薄膜扩散梯度技术（DGT）作为水质监测采用的补充方法的可能性已经得到验证，通过3个采样活动来衡量目前在高度城市化的河流地表水的微量金属元素（镉，钴，铬，铜，铅，镍，锌等）。具体来说，帕西格河的研究宗旨是：评估DGT被动采样器在变化强烈的水文条件（偶发事件影响）和泥沙扰动的城市背景下的适用性，并提出一个更好地水资源管理的建议。研究结果表明：（1）DGT非常适合作为常规水质监测分析的一部分。（2）DGT可以在流态变化强烈的情况下监测出通量数据。（3）DGT适合跟踪河湖口处不稳定的金属通量。（4）马里基纳河的汇合处的水资源管理应加强。此外，建议制定相关水质监测协议和管理方案。

Abstract：The potential of the Diffusive Gradient Thin-Films (DGT) as a supplemental method for water quality monitoring was employed has been tested through 3 sampling campaigns to measure the trace metals (Cd, Co, Cr, Cu, Pb, Ni and Zn) present in the surface water of a highly urbanized river. Specifically, the study done in the Pasig River (Philippines) seeks to: assess the applicability of DGT passive sampler in an urban context exhibiting highly contrasted hydrological conditions (greatly influenced by episodic events) and sediment disturbance (dredging) and provide proposal for a better water management. The results indicate that: (1) DGT is highly recommended as part of a routine analysis for water quality monitoring; (2) DGT are able to capture the fluxes even in very contrasted flow regimes; (3) DGT are suitable to trace the labile fluxes of metals from the lake to the estuary; and (4) at the confluence of the Marikina River water management should be intensified. Moreover, recommendations were made for developing pertinent water monitoring protocol and management scheme.
