Abstract

Exposure to environmental pollutants is known to be harmful to health, in general, and to lungs in particular. In this respect, TRAFFIC POLICE officers are at particular risk due to the nature of their jobs, since they are exposed to emissions, such as asbestos produced by vehicles and others. In a field study, personal asbestos fiber concentrations during the routine police work in Tehran were measured. The airborne asbestos fiber concentrations and their chemical composition of 42 personal samples were analyzed by Phase Contrast Microscopes (PCM) and Scanning Electron Microscopes (SEM) equipped with an Energy Dispersive X-ray analyzer (EDX). Personal monitoring of fiber levels in the police stations demonstrated counts that ranged from 0.006 to 0.027 PCM f/ml. The personal geometrical mean concentrations were 0.014 PCM f/ml which is considerably higher than the geometrical mean concentrations reported in ambient of Tehran (3.4× 10-3 f/ml). The SEM data demonstrate that the fibrous particles consisted, approximately, of Chrysotile (60%) and Actinolite (20%). Based on these findings, the 60% of airborne fibers inhaled by police officers were serpentine asbestos with fibers equal and greater than 5 mm in length and 0.2mm in diameter, and thus were not included in the PCM – based fiber counts. Thus, it is expected that the police officers who work in Tehran will suffer from negative health effects due to exposure to the asbestos fibers.
