We modeled Group A Rotavirus (RVA) and Norovirus genogroup II (GII NoV) transport experiments in standardized (crystal quartz sand and deionized water with adjusted pH and ionic strength) and natural soil matrix-water systems (MWS). On the one hand, in the standardized MWS, Rotavirus and Norovirus showed very similar breakthrough curves (BTCs), showing a removal rate of 2 and 1.7 log₁₀, respectively. From the numerical modeling of the experiment, transport parameters of the same order of magnitude were obtained for both viruses. On the other hand, in the natural MWS, the two viruses show very different BTCs. The Norovirus transport model showed significant changes; BTC showed a removal rate of 4 log₁₀, while Rotavirus showed a removal rate of 2.6 log₁₀ similar to the 2 log₁₀ observed on the standardized MWS. One possible explanation for this differential behavior is the difference in the isoelectric point value of these two viruses and the increase of the ionic strength on the natural MWS.

在标准和天然土壤基质-水系统中模拟人类轮状病毒和诺如病毒的运输。

我们模拟了A组轮状病毒（RVA）和诺如病毒基因组II（GII NoV）在标准化（结晶石英砂和去离子水，pH和离子强度已调整）和天然土壤基质-水系统（MWS）中的运输实验。一方面，在标准化的MWS中，轮状病毒和诺如病毒显示出非常相似的突破曲线（BTC），去除率分别为2和1.7 log ₁₀。从实验的数值模型中，两种病毒都获得了相同数量级的运输参数。另一方面，在自然MWS中，两种病毒显示出截然不同的BTC。诺如病毒的运输模型显示出重大变化。BTC显示去除率为4 log ₁₀，而轮状病毒显示去除率为2.6 log ₁₀类似于在标准MWS上观察到的2 log ₁₀。这种差异行为的一种可能解释是这两种病毒的等电点值不同以及天然MWS上离子强度的增加。
