The survival of infectious bronchitis (IB) virus in water [PDF]
Avian Pathology, 1973 Observations on the survival of infectious bronchitis virus in 3 mains waters showed that it survived for a much shorter period in one of them which contained a relatively high content of copper (0.2 mg/1). Other factors adversely affecting survival were 5 ppm of free residual chlorine and increase in temperature over the range of 20-35 degrees C ...
