A novel coronavirus (SARS-CoV-2) has caused more than 150 million confirmed infections worldwide, while it is not clear whether it affects the coastal waters. This paper proposed a biophysical model based on 16 scenarios with different virus half-life parameters to assess potential viral contamination from 25 municipal sewage outfalls into the Bohai Sea. Viral concentration maps showing spatial and temporal changes are provided based on a biophysical model under multiple scenarios. Results demonstrate that adjacent sea areas can become exposed to SARS-CoV-2 via water-borne transport from outfalls, with a higher risk in winter, because SARS-CoV-2 can be highly stable at low temperature. As coastal waters are the ultimate sink for wastewater and the epidemic will last for long time, this work is of great importance to raise awareness, identify vulnerable areas for marine mammals, and avoid the risk of exposure of tourists at bathing beach.

一种新型冠状病毒 (SARS-CoV-2) 已在全球范围内造成超过 1.5 亿确诊感染，但尚不清楚它是否会影响沿海水域。本文提出了一种基于 16 个具有不同病毒半衰期参数的情景的生物物理模型，以评估从 25 个城市污水排放口进入渤海的潜在病毒污染。基于多种情景下的生物物理模型，提供了显示时空变化的病毒浓度图。结果表明，邻近海域可以通过排放口的水传播暴露于 SARS-CoV-2，冬季风险更高，因为 SARS-CoV-2 在低温下可以高度稳定。由于沿海水域是废水的最终汇，而且这种流行病会持续很长时间，因此这项工作对于提高认识具有重要意义，
