该流域为确定水生污染物、环境健康和人类健康之间的联系提供了物质基础。目前建立这种联系的努力受到环境和流行病制约因素的限制。环境限制包括难以描述农业径流的时空动态，难以充分了解这些化合物在环境中的降解和代谢，以及难以了解复杂的混合物。流行病学的局限性包括与风险因素数据的组织有关的困难，以及关于哪些可测量的终点最适合农业环境的不确定性。然而，我们认为，采用分水岭概念可以减轻其中一些困难。从环境的角度来看，流域概念有助于在与人类健康结果相关的分辨率水平上确定土地使用和农用化学品应用的差异。从流行病学的角度来看，分水岭概念将数据置于与环境相关的结构中。在这篇观点论文中，我们讨论了流域如何为环境和人类健康研究提供一个概念框架。
The watershed provides a physical basis for establishing linkages between aquatic contaminants, environmental health and human health. Current attempts to establish such linkages are limited by environmental and epidemiological constraints. Environmental limitations include difficulties in characterizing the temporal and spatial dynamics of agricultural runoff, in fully understanding the degradation and metabolism of these compounds in the environment, and in understanding complex mixtures. Epidemiological limitations include difficulties associated with the organization of risk factor data and uncertainty about which measurable endpoints are most appropriate for an agricultural setting. Nevertheless, it is our contention that an adoption of the watershed concept can alleviate some of these difficulties. From an environmental perspective, the watershed concept helps identify differences in land use and application of agrichemicals at a level of resolution relevant to human health outcomes. From an epidemiological perspective, the watershed concept places data into a construct with environmental relevance. In this perspectives paper, we discuss how the watershed can provide a conceptual framework for studies in environmental and human health.
