Correlation of Symptoms and Duration of Exposure with Estimated Lung Age in Cement Factory Workers at Chengalpet District-Tamilnadu

Abstract

Cement manufacturing is a major industrial activity associated with significant occupational exposure to airborne particulate matter. Cement dust contains respirable particles such as crystalline silica, calcium oxide, and other alkaline compounds that can penetrate deep into the respiratory tract and cause adverse pulmonary effects. Chronic exposure to cement dust has been recognized as an important risk factor for respiratory morbidity, leading to airway inflammation, mucosal irritation, and progressive decline in lung function [1].
