title: Effect of smelter emissions on the hemogram of the deer mouse (Peromyscus maniculatus).
abstract: Blood samples were obtained from 284 deer mice (Peromyscus maniculatus) live-trapped near two base metal smelters in northern Manitoba, Canada. Hemoglobin and hematocrit values were significantly higher in mice trapped within 40-70 km of the smelters compared to those in control areas 185 to 190 km from the smelter. These increases appear to be normal physiological responses to a mild respiratory stress, as in a true secondary polycythemia of anoxic tupe. The mice are sensitive bioindicators of sulphur dioxide emissions that apparently induce the higher blood values.
