Respiratory effects of work in retail food stores. II. Respiratory symptoms.
研究了零售食品店员工呼吸系统症状与工作环境暴露的关系，发现接触肉类包装操作（尤其是聚氯乙烯薄膜切割排放物）的员工出现气道狭窄症状的比例更高，但无法确定是刺激效应还是过敏反应。
This study examined the relationships between the prevalence of respiratory tract symptoms and estimates of environmental exposures in retail food stores, in particular exposures to emissions from the cutting of polyvinyl chloride wrap. When respiratory symptoms were compared with a measure of cumulative exposure, there was evidence that the prevalence of symptoms of episodic airway narrowing was higher for workers who had been exposed directly or indirectly to meat wrapping operations independent of a significant association of these symptoms with allergic or asthmatic history. Whether this finding reflects a nonspecific irritant effect or allergic sensitization cannot be determined from these data. No single substance present in the work environment studied has, as yet, been identified as associated with these effects.
