Abstract

Background: Environmental pollution is a worldwide phenomenon. Exposure to vehicle emissions increases the risk to reduced lung function and detoriating cardiovascular performance.

Aims & Objective: To measure the effect of dust and automobile exhaust fumes on security guards.

Material and Methods: The study was conducted in 150 healthy non-smoking male security guards of age group 20-40yrs. Peak Expiratory Flow Rate (PEFR) was measured using Wrights peak flow meter and acute changes in oxygen saturation (SPO2) were determined using Digital finger Pulse Oximeter in equal number (n=50 each) of security guards working outside office, in open parking and in basement parking. Statistical analysis was carried out by unpaired student’s t -test.

Results: PEFR was found to be lower (427.0 ± 11.12 L/min) in security guards working in basement parking of shopping malls as compared to security guards working in open parking (430 ± 12.92 L/min) and outside office buildings (443 ± 13.29 L/min). Acute change in Oxygen saturation, (SPO2) were normal in each occupation but were significantly lower in security guards in basement parking p
