Title Dose-response relationships between occupational aerosol exposures and cross-shift declines of lung function in poultry workers: Recommendations for exposure limits
Bibliographic information Mar. 2000, Vol.42, No.3, p.260-269. Illus. 36 ref.
Abstract Previous dose-response research on swine workers has resulted in US exposure limit recommendations of 2.5mg/m3 for total dust, 0.23mg/m3 for respirable dust, 100EU/m3 for endotoxin and 7ppm for ammonia. No similar recommendations had been reported previously for poultry workers. Therefore, a study was conducted to examine dose-response relationships of bioaerosol exposures and worker respiratory health in this industry. 257 poultry workers were studied for respiratory symptoms, pulmonary function and exposure to dust (total and respirable), endotoxins and ammonia. The relationships between exposures and response were studied by correlation and multiple regression. Significant dose-response relationships were observed between exposures and pulmonary function decrements over a work shift. Exposure concentrations associated with significant pulmonary function decrements were 2.4mg/m3 for total dust, 0.16mg/m3 for respirable dust, 614EU/m3 for endotoxins and 12ppm for ammonia.
