INTRODUCTION
Waste handling workers are exposed to air pollutants and toxic compounds produced during waste management and processing that can cause respiratory symptoms and lung function impairment. This study aimed to evaluate the respiratory health of exposed workers in a waste management plant in Attica, Greece.
METHODS
50 field workers exposed to outdoor pollutants (exposure group) and 32 office clerks with no exposure (control group) were evaluated. Upper and lower respiratory symptoms were documented and spirometry was performed.
RESULTS
There was no statistically significant difference between the exposure and the control group in forced expiratory volume in one second (FEV1)%, forced vital capacity (FVC)%, FEV1/FVC% predicted values. Workers had lower maximal mid-expiratory flow (MMEF)% predicted values compared to controls (82% vs 94%, p=0.019). No difference was observed regarding the respiratory symptoms between the two groups.
CONCLUSION
Lower MMEF values were observed in the exposure group. Low MMEF can be indicative of small airway disease, thus smoking cessation, close follow-up, and the use of personal protective equipment are recommended.
引言
垃圾处理工人会接触到垃圾管理和处理过程中产生的空气污染物和有毒化合物，这些物质可能导致呼吸道症状和肺功能损害。本研究旨在评估希腊阿提卡一家垃圾处理厂中接触污染物的工人的呼吸健康状况。
方法
对50名接触室外污染物的现场工人（暴露组）和32名无暴露的办公室职员（对照组）进行了评估。记录了上、下呼吸道症状，并进行了肺活量测定。
结果
暴露组和对照组在一秒用力呼气量（FEV1）%、用力肺活量（FVC）%、FEV1/FVC%预测值方面无统计学显著差异。与对照组相比，工人的最大呼气中期流速（MMEF）%预测值较低（82%对94%，p = 0.019）。两组在呼吸道症状方面未观察到差异。
结论
在暴露组中观察到较低的MMEF值。低MMEF可能表明存在小气道疾病，因此建议戒烟、密切随访并使用个人防护设备。
