ABSTRACTIntroduction: The use of chemicals to protect against pests is a common practice in the floriculture, implementing the concepts of integrated cultivation of these safeguards ensuring the necessary quantity and quality of net product required to meet international demand. Biomonitoring has been used in a variety of occupational and environmental studies to determine exposures to pesticides. Materials and Methods: A cross-sectional study was conducted on 300 workers linked to 15 companies, with the aim of characterizing the exposure to the pesticide methamidophos in flower company workers in the Bogotá (Cundinamarca) and Rionegro (Antioquia). A survey was conducted, which included sociodemographic, occupational and toxicological variables and urine samples were collected to determine the pesticide methamidophos. Results: It is noted that the workforce belongs mostly to the urban area (88. 5%) and the share of female aged between 19 and 58 years with an average of 36. 7 years is highlighted. The office where most of the workers was growing and was cut to 52. 5%. Working time in the flower industry was reported minimum of 12 (3. 3%) and up to 22 years (6. 1%). As for personal protection elements, 96. 1% (344) states use in their work. The average methamidophos at the beginning of the day was 29. 12 mg / l and at the end of the day 15. 70 mg / l. Conclusions: This work allowed to know the landscape of exposure to the pesticide methamidophos and constitutes a step forward in research on the topic and also to track workers through their inclusion in epidemiological surveillance.
