| survival of natural sewage populations of enteric bacteria in diffusion and batch chambers in the marine environment. | the survival of natural populations of escherichia coli and enterococci in sewage was measured in large-volume diffusion chambers in an estuary and a salt marsh. the 5-liter chambers, with polycarbonate membrane sidewalls, were found to be suitable for up to week-long experiments. decay rates, measured monthly from february to august 1978, ranged from 0.042 to 0.088 h(-1) (time for 90% of the population to die = 25 to 55 h) for e. coli and 0.019 to 0.083 h(-1) (time for 90% of the population to ... | 1983 | 6405693 |
