CONTEXT
Wholesale vegetable market is a rich source of generation of organic dust as loads of fruits and vegetables are loaded and unloaded here daily. Thus, regular workers are exposed to this organic dust for a considerable period of time depending on their work schedule. This study was planned to determine the microbial status of organic dust and to explore its association with pulmonary functions in the workers of wholesale vegetable market in Rishikesh.
MATERIALS AND METHODS
It was a cross-sectional exploratory/observational study. Thirty-five apparently healthy adult males were selected from vegetable market having no history of any chronic illness. Smokers and alcoholic were excluded from the study. The same number of age- and sex-matched controls with the same exclusion criteria were recruited from workers not working in the vegetable market and also not exposed to any other kinds of organic dust. Microbial culture of air in the vegetable market was done. It was compared with the microbial status of air in the working place of controls. Pulmonary functions of all the workers were performed with the help of digital spirometer (Helios 401).
RESULTS
Bacterial and fungal concentration was found to be significantly higher in the air of vegetable market as compared to air in the workplace of controls (such as coagulase-negative staphylococci >25 colony-forming unit (CFU) at incubation temperature vs. 10-12 CFU at incubation temperature, significant growth of , , and nonalbicans in vegetable market as compared to workplace of controls). Pulmonary function parameters (percentage forced expiratory volume in 1 s (FEV), percentage predicted forced expiratory flow in mid-half of expiration, and FEV) of workers exposed to organic dust in vegetable market were also significantly lower ( < 0.05).
CONCLUSION
Exposure of organic dust is associated with compromised pulmonary functions and there is a need of formulation of safety guidelines.
背景
批发蔬菜市场是有机粉尘的丰富来源，因为每天都有大量的水果和蔬菜在此装卸。因此，根据工作安排，长期工人会在相当长的一段时间内接触这种有机粉尘。本研究旨在确定有机粉尘的微生物状况，并探讨其与瑞诗凯诗批发蔬菜市场工人肺功能的关系。
材料与方法
这是一项横断面探索性/观察性研究。从蔬菜市场挑选35名表面健康、无任何慢性病病史的成年男性。吸烟者和酗酒者被排除在研究之外。从不从事蔬菜市场工作且未接触任何其他种类有机粉尘的工人中招募了相同数量、年龄和性别匹配且具有相同排除标准的对照组。对蔬菜市场的空气进行了微生物培养。将其与对照组工作场所的空气微生物状况进行比较。所有工人的肺功能均借助数字肺活量计（Helios 401）进行检测。
结果
发现蔬菜市场空气中的细菌和真菌浓度显著高于对照组工作场所的空气（如凝固酶阴性葡萄球菌在培养温度下>25菌落形成单位（CFU），而对照组在培养温度下为10 - 12 CFU，与对照组工作场所相比，蔬菜市场中 、 和非白色念珠菌有显著生长）。蔬菜市场中接触有机粉尘的工人的肺功能参数（1秒用力呼气容积百分比（FEV）、呼气中期用力呼气流量预测百分比和FEV）也显著较低（<0.05）。
结论
接触有机粉尘与肺功能受损有关，需要制定安全指南。
