[Evaluation of cyclists exposure to air pollution: a literature review].

Objectives: To describe and interpret the methodologies and results of the main studies related to the monitoring of exposure of cyclists to air pollution.

Methods: Research and analysis of national and international research of the last ten years in the Cochrane, Scopus, Embase, Science Direct and Pubmed databases. The search was conducted in August and September 2017 using the following search descriptors for MeSH: air pollution, bicycle riding, environmental exposure, environmental health, exposure by inhalation, environmental pollutants, transportation, public health and toxicology.

Occupational exposure to air pollutants: particulate matter and respiratory symptoms affecting traffic-police in Bogotá.

Objectives: Quantifying personal exposure to particles less than 10 micrometres in diameter (PM10) and determining the prevalence of respiratory symptoms in traffic-police officers working in Bogotá's metropolitan area.

Methods: This was a cross-sectional study of 574 traffic-police officers divided into two groups (477 traffic-police and 97 police working in an office). They were given a questionnaire inquiring about respiratory symptoms, toxicological medical evaluation, lung function tests and personal PM10 monitoring.

[Quantifying polycyclic aromatic hydrocarbons in urine samples taken from traffic police working in Bogota's metropolitan area].

Objective: Quantifying polycyclic aromatic hydrocarbon levels in urine samples taken from a population of traffic police working in the metropolitan area of Bogotá who were occupationally exposed to 1-hydroxypyrene (1-OHP) and 3-hydroxy-benzo[a]pyrene (3-BaP) metabolites from polycyclic aromatic hydrocarbons (PAH) having toxicological interest, related to their detection, and a degree of exposure to particulate material having a size less than 10 micrometres (PM10) and/or other factors.

Methods: A cross-sectional study was made of 524 traffic police, 413 of whom were engaged in operational and 111 in administrative functions. Urine samples were taken from all the individuals included in the study for determining PAH metabolites by gas chromatography/mass spectrometry (GC/MS).
