Table 1. The various treatments and aquarium numbers. The mean survival time (time to the disappearance of the DNA) is calculated as total time on test divided by the number of aquaria in which the DNA disappeared, meaning that it was at that time for the first time below the detection limit of 8,221 molecules per liter.
