Occupational Exposure to Airborne Contaminants and Associated Health Risk in a University-Based Cafe

Abstract

Indoor Air Quality (IAQ) is an essential component of workplace safety, especially in enclosed food service settings where cooking operations, maintenance activities, and high customer density lead to increased exposure to airborne contaminants. These pollutants, including particulate matter (PM), volatile organic compounds (VOCs), and carbon oxides, can cause serious respiratory illnesses or chronic diseases. This study evaluates IAQ and associated health risks among staff at two university-based cafes, Mvnchbites Cafe and Dani’s Tea & Coffee at UiTM Shah Alam. The primary objectives were to measure contaminant concentrations, identify worker health symptoms, and assess potential health risks associated with long-term exposure.
