Abstract

In order to survey the occurrence of waterborne viruses in Korean surface water, a total of 192 water samples from July 2003 to January 2006 were collected and analyzed. The presence of waterborne viruses was investigated by total culturable virus assay (TCVA) using buffalo green monkey kidney (BGMK) cells. The results showed that 63 of 192 samples (32.8%) were positive for waterborne viruses with the average concentration of 3.1±18 most probable numbers (MPN)/100 L. The relationship between the occurrence of the viruses and the physicochemical environmental factors revealed that there was a significant correlation between the turbidity of water and the occurrence of the viruses. It was also noted that the water temperature might have some relationship with the occurrence of the viruses, as the frequency of the viruses was higher in low temperature or winter season. Therefore, the occurrence of waterborne viruses in Korean surface water might be affected by the physicochemical environmental factors such as turbidity and water temperature.
