标题：微生物病原体在农业环境中的运移和归宿Title: Transport and fate of microbial pathogens in agricultural settings关键词：模型 病原体 滞留 存活 运移
Keywords: models pathogen retention survival transport摘要：需要了解微生物病原体（以下简称病原体）在农业环境中的运移和存活情况，以评估病原体对水和食物资源的污染风险，并制定控制策略和治理方案。然而，在预测径流及随后通过的浅层包气带和地下水中病原菌的归宿和运移方面仍存在许多知识空白。描述病原体在农业环境中的归宿常常需要涉及大量运移途径、过程、因素和数学模型。土壤异质性以及温度、水分输入和病原体来源的时间变异性显著增强了复杂性水平。病原体的迁移路径存在很大的变异性，导致控制病原体在不同时空尺度上迁移的主导过程发生变化。例如，强降雨事件可以产生径流和优先流，可以快速运输病原体。长时间存活的病原体在受到这种快速运移事件的影响时保持存活的可能性大大增加。相反，在干旱季节，病原体的运移更强烈地依赖于多种环境表面的滞留作用，这些环境表面由许多耦合的物理、化学和微生物因素控制。这些交互作用并未得以完全表征，导致即使在柱实验规模上仍缺乏模拟病原体运移的合理数学框架的共识。此外，对于如何量化农田或流域尺度上的运移和存活参数知之甚少。本综述总结了在宽范围的时空尺度上农业环境中病原体运移和归宿的现有概念和定量模型。作者还讨论了通过改进模型可以实现的益处，以及减轻水传播疾病风险的潜在措施。Abstract: An understanding of the transport and survival of microbial pathogens (pathogens hereafter) in agricultural settings is needed to assess the risk of pathogen contamination to water and food resources, and to develop control strategies and treatment options. However, many knowledge gaps still remain in predicting the fate and transport of pathogens in runoff water, and then through the shallow vadose zone and groundwater. A number of transport pathways, processes, factors, and mathematical models often are needed to describe pathogen fate in agricultural settings. The level of complexity is dramatically enhanced by soil heterogeneity, as well as by temporal variability in temperature, water inputs, and pathogen sources. There is substantial variability in pathogen migration pathways, leading to changes in the dominant processes that control pathogen transport over different spatial and temporal scales. For example, intense rainfall events can generate runoff and preferential flow that can rapidly transport pathogens. Pathogens that survive for extended periods of time have a greatly enhanced probability of remaining viable when subjected to such rapid-transport events. Conversely, in dry seasons, pathogen transport depends more strongly on retention at diverse environmental surfaces controlled by a multitude of coupled physical, chemical, and microbiological factors. These interactions are incompletely characterized, leading to a lack of consensus on the proper mathematical framework to model pathogen transport even at the column scale. In addition, little is known about how to quantify transport and survival parameters at the scale of agricultural fields or watersheds. This review summarizes current conceptual and quantitative models for pathogen transport and fate in agricultural settings over a wide range of spatial and temporal scales. The authors also discuss the benefits that can be realized by improved modeling, and potential treatments to mitigate the risk of waterborne disease transmission.
