The danger was a alloying of 89% sidestream smoke, which comes from the cut off of a lit cigarette and is exposed to the predominantly trunk, and 11% mainstream smoke, which is smoke straight away inhaled principally the rats. The rats were exposed with a view two three-hour shifts twice a time, separated principally a two-hour break out of.
This proportion was chosen because of its similarity to the possibly manlike wisdom with second-hand smoke, said Dr. Kratzer. "This is much what a good-natured would be exposed to at a pole or casino."
