220 workers (male 152, female 68) who produce and use yellow phosphorus were named as the observation group and 120 workers who were exposed to oxalic acid as the control group were investigated. The concentration of P_2O_5 in the air of yellow phosphorus working environment was measured continuously for 3 days with the average concentration of 0.1-3 mg / m ~ 3. Phyllolith X-ray was performed on those workers who were exposed to yellow phosphorus for more than 5 years of service. Physical examination results show that: the clinical manifestations of the observation group is mainly
