Effects of mild cold stress on the survival of seawater-adapted Mallard ducks (Anas platyrhynchos) maintained on food contaminated with petroleum

Journal Article · · Environ. Res.; (United States)
Seawater-adapted Mallard ducks were maintained on a 100-day diet of petroleum derivative or crude oil contaminated food supply with only minimal changes in mean body weight being observed. Mortality rates due to continuous mild cold stress were higher among petroleum-contaminated food groups than uncontaminated food control groups. Autopsy revealed adrenal hypertrophy and lymphoepithelial involution as characteristics of the birds that died, indicating adrenocortical stimulation preceding death.
