title: Transport of nitrite across fish gills.
abstract: The results show that rainbow trout (Salmo gairdneri) are able to concentrate NO2- ions in the blood plasma. After 24 hr in water containing 0.7 mM/l NO2-, the blood plasma contained about 5 mM/l NO2- suggesting that the gills have the ability to transport NO2 against a concentration gradient.
