Tobacco smoke occupational exposure: biomarkers of biological damage

Abstract

High concentration of toxic substances emanated from tobacco smoke in entertainment places such as restaurants, bars and nightclubs may compromise indoor air quality (IAQ) generating environments of likelihood health risk. Their employees, particularly those exposed to second-hand smoke, are at increased risk for developing chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma and lung cancer. Objectives In this work, we aimed at evaluating relationships between occupational ETS exposure, biological damage (DNA or proteome alterations) and putative respiratory dysfunctions.
