在美国得克萨斯州加尔维斯顿湾，研究了脊髓灰质炎病毒1型(LSC)和埃科病毒1型(Farouk)在河口水和沉积物中的存活情况。病毒悬浮在河口水和沉积物中，在透析管和由聚碳酸酯膜壁建造的房间中。在两种类型的舱中，海水中的病毒灭活率相似。病毒在底泥上的吸附大大延长了存活时间。将99%(T-99)的脊髓灰质炎病毒灭活所需的时间从仅在海水中的1.4天增加到在相对不受污染的地点将病毒吸附到沉积物上的6.0天。在污染较重的地点，由于病毒吸附到沉积物中，脊髓灰质炎病毒T-99从大约1小时增加到4.25天。在野外条件下，病毒与河口沉积物的结合可延长其在海洋环境中的生存时间。
The survival of poliovirus 1 (LSc) and echovirus 1 (Farouk) in estuarine water and sediment was studied in Galveston Bay, Texas, USA. Viruses were suspended in estuarine water and sediment in dialysis tubing and in chambers constructed with polycarbonate membrane walls. Virus inactivation rates in seawater were similar in both types of chambers. Virus adsorption to sediment greatly increased survival time. The time required to inactivate 99% (T-99) of poliovirus increased from 1.4 days in seawater alone to 6.0 days for virus adsorbed to sediment at a relatively nonpolluted site. At a more polluted site, poliovirus T-99 was increased from approximately 1 h to 4.25 days by virus adsorption to sediment. Under field conditions virus association with estuarine sediment acts to prolong its survival in the marine environment.
