BACKGROUND
Stone quarrying activities generate dust and fine particulate matters of silica and heavy metals. The prolonged exposure to suspended particulates leads to fatal respiratory complications. Occupational pulmonary complications are poorly characterized among quarry workers in Tamil Nadu.
OBJECTIVES
This study aims to assess pulmonary function and determine the associated risk factors among quarry workers.
MATERIALS AND METHODS
A comparative, cross-sectional study was conducted from April 2014 to January 2015 among workers at seven stone quarries in Chennai and residents within a 5 Km radius. Pulmonary function tests (PFT) and sputum analysis were done.
RESULTS
Overall, 670 participants were enrolled in the study, with a median age of 37 years. Comparatively, the mean PFT measures were significantly lower in quarry workers with a higher proportion of airflow obstruction and tuberculosis infection.
CONCLUSION
The risk of airflow obstruction among quarry workers increased with smoking and longer duration of work years in quarry.
背景
采石活动会产生粉尘以及二氧化硅和重金属的细颗粒物。长期接触悬浮颗粒物会导致致命的呼吸系统并发症。在泰米尔纳德邦的采石工人中，职业性肺部并发症的特征尚不明确。
目的
本研究旨在评估采石工人的肺功能并确定相关危险因素。
材料与方法
2014年4月至2015年1月，在钦奈的七个采石场工人以及半径5公里范围内的居民中进行了一项对比性横断面研究。进行了肺功能测试（PFT）和痰液分析。
结果
总体而言，670名参与者纳入了研究，中位年龄为37岁。相比之下，气流阻塞和结核感染比例较高的采石工人的平均PFT指标显著较低。
结论
采石工人气流阻塞的风险随着吸烟以及在采石场工作年限的延长而增加。
