Across-shift changes in the pulmonary function of meat-wrappers and other workers in the retail food industry.
研究了83名零售食品工人班次前后的肺功能变化，发现无哮喘或过敏史的工人中，接触热丝切割塑料膜与肺功能急性下降无关，但有哮喘或过敏史的工人可能对热丝包装排放产生急性反应。
Pulmonary function was measured before, during, and after the end of the workshift in 83 workers in the retail food industry. All acute changes in forced expiratory volume in 1 s were standardized for lung size before the magnitude of the changes were compared between the workers exposed and unexposed to the use of hot wires for cutting plastic film. No association was found between acute drop in pulmonary function and either direct or indirect exposure in the absence of a history of asthma or allergy to inhaled materials. The borderline significance of an interaction term between exposure and asthma/allergy in a regression analysis suggests that workers with a history of asthma or atopy may have an acute response to hot-wire wrapping emissions.
