The Subchronic Effects of Repeated Exposure to White Phosphorus/Felt Screening Smokes in Rats
Abstract
Toxicity studies were conducted to determine the subchronic effects of repeated exposure to three concentration levels of a white phosphorus screening smoke. When white phosphorus burns, it forms a number of oxides of phosphorus which are rapidly converted by moisture to phosphorus and phosphonic acids. It would appear that the chance of injury is high at 1161 mg/m cu and low at 193 mg/m cu. At 589 mg/m cu, one-half of the rats showed some exposure effects. The rats apparently developed a tolerance to repeated exposures, particularly at the lowest level.
