| Abstract |
Report on animal experiments with gallium arsenide (GaAs) dust. The acute effect thresholds were 152.5mg/m3 (inhalation), and 7,000mg/m3 (intragastric administration). No irritant effect on skin was observed. Retention coefficient: 5.2. A 4-month exposure to 12mg/m3 induced significant changes in rectal temnperature and physiological thresholds, and an increase in body weight. Erythrocyte count increased after 2-month exposure, but decreased progressively after 3 months. Recommended TLV for GaAs dust: 2mg/m3. |
