Table 4.

Inactivation parameters of SARS-CoV-2, MSA and PMMoV RNA in river water and seawater, first-order decay rates were estimated by linear regression. 95% confidence intervals (CI) have been included. ns: non-significant deviation from the model. s: stable for the duration (20 days) of the experiment.
