<p>The research seeks to exploratively analyze the routes of contamination caused to the population and the environment using organophosphate pesticides in the municipality of Guasca in the department of Cundinamarca and its implications for areas of high population density such as the city of Bogotá. The investigation was carried out by means of water and soil sampling, identifying eight priority points according to the presence of agricultural activities with the use of pesticides near schools surrounded by crops. The samples were analyzed under the methodology of the EPA, through method 8141B, which provides gas chromatographic conditions for the determination of concentrations per billion organophosphate compounds&nbsp; and the method 8081B widely used for the analysis of organochlorine pesticides in diverse and complex sample matrices. Regarding the perception analysis, six interviews were conducted with people who live or worked in agricultural areas. These interviews allowed knowing the use of pesticides, the possible effects on water sources, soil and the health of the population involved, such as schools and homes close to the application areas and crops. It is relevant to carry out this kind of study since fumigation activities on different crops represent the work environment and over which there is no effective control, however, some health experts consider that the personal environment, influenced by different factors, It is the most important for people's well-being.</p>
