Exposure to Pesticides in Residents or the Banks of the Río Bogotá (Suesca) and the Capitan Fish

Objective: Considering the high use of pesticides in Colombia and the harmful effects resulting from exposure to these substances on human health and the environment, a study for the determination of biomarkers of exposure and effect of pesticides in population of the banks of the Río Bogotá in Suesca, the levels of pesticides in river water samples taken in the same city and in samples of fish, “Capitán de la Sabana” (Eremophylus mutisii) caught in this area. Materials and methods: We measured for organophosphates, carbamates, dithiocarbamates and organochlorines. We also explored through a survey of occupational exposure to pesticides in the population and knowledge and use of personal protective measures in their work. Additionally, we explored the habit of fishing for captain and consumption in the diet of the inhabitants of the riverbank. Results: The results show the presence of organochlorine and organophosphorus pesticides in the river and in fish tissue and organochlorine and ethylene thiourea in human biological samples. Participated in the study workers directly exposed to pesticides, highly toxic handlers, most know and use personal protective measures and industrial hygiene. Conclusions: Pollution such as pesticides in the upper basin of Bogotá that affects wildlife and coastal populations. Best action is necessary to promote environmental care, protection and self-care of persons using pesticides in the area.
