title: [Proposal to establish an environmental contaminants surveillance system in Colombia].
abstract: Environmental pollution is a growing problem that negatively impacts health with social and economic high costs. In this sense, coordinated surveillance of conditions, risks, exposures and health effects related to pollution is a useful tool to guide decision-making processes. The objective of this essay was to describe a surveillance system for environmental contaminants in Colombia and its design background. Using the technical guidelines proposed by the Pan American Health Organization, a literature review was conducted to identify the key elements to be included in such surveillance system and to establish which of these elements were already present in the Colombian context. Moreover, these findings were compared with successful experiences in Latin America. The surveillance system includes five components: Epidemiological, environmental and biological surveillance, clinical monitoring and recommendations to guide policies or interventions. The key factors for a successful surveillance system are: interdisciplinary and inter-sector work, clear definition of functions, activities, data sources and information flow. The implementation of the system will be efficient if the structures and tools existing in each country are taken into account. The most important stakeholders are inter-sector public health and environmental commissions and government institutions working in research and surveillance issues related to health, sanitation, environment, drugs and food regulation and control. In conclusion, Colombia has the technical resources and a normative framework to design and implement the surveillance system. However, stakeholders´ coordination is essential to ensure the efficacy of the system so it may guide the implementation of cost-effective actions in environmental health.
