Leather Tannery Emitted Particulate Matter Induced Pulmonary Risk Factors: Causative Agents and Synergists

Leather tanneries are known to produce harmful particulate matter (PM), leading to various respiratory and other health issues among workers. While studies have linked PM exposure to respiratory ailments, research on PM composition and its association with health risks in tanneries is limited. This study aimed to investigate PM composition, size-based exposures, and associated health risks among tannery workers.

A comprehensive literature review was conducted, focusing on PM characteristics, occupational exposures in tanneries, and pulmonary impairments. Results showed that tannery workers exhibited lung function decline, with a mixed pattern of restrictive and obstructive disorders. PM analysis revealed diverse airborne metal concentrations within acceptable limits but posing respiratory and cancer risks. Chromium, carbon and bacterial pathogens emerged as major concerns.

The organic carbon and bacterial species were identified as both contributors and synergists to respiratory ailments, with bacterial associations more prominent in larger PM sizes. Smoking further exacerbated lung damage, synergizing with PM exposure.
