RESUMEN

Objetivo: caracterizar geográficamente, en territorio colombiano, las fuentes de agua potable y los índices colectivos de fluorosis dental que indican exposición a fluoruro a nivel comunitario. Métodos: se realizó un estudio descriptivo a partir de dos fuentes de información: el Subsistema de Información de Vigilancia de Calidad de Agua Potable (SIVICAP) y el Sistema de Vigilancia en Salud Pública (Sivigila). Los análisis se realizaron desde 2012 hasta 2018, implementando ponderación de los riesgos por exposición a fluoruro en agua para determinar los siguientes niveles de riesgo: sin riesgo, riesgo para fluorosis dental y riesgo para fluorosis esquelética. Se cálculo el índice colectivo de fluorosis (ICF) dental y se presentaron los resultados en mapas geográficos. Resultados: los departamentos de Nariño, Boyacá, Quindío, Valle del Cauca y Cundinamarca presentaron el mayor número de muestras de agua analizadas (60,5 %); 14 presentaron concentraciones superiores a 4 ppm y 10 municipios concentraciones entre 1,01 y 4 ppm. La vigilancia centinela de la exposición a flúor mostró que 3 municipios presentaron ICF >3, lo que significa un riesgo muy grave. En cuanto al riesgo grave se encontraron 52 municipios de 21 departamentos, principalmente en la región Andina y Caribe. Nariño fue el departamento con mayor número de municipios en riesgo grave. Conclusiones: se identificaron riesgos ambientales en agua, y biológicos por altos índices colectivos de fluorosis dental, que, espacialmente, se ubican en la región Andina, aunque los riesgos en agua se pueden explicar porque en esta región se realiza con mayor frecuencia vigilancia de calidad del agua.


Objective: To geographically characterize in colombian territory, drinking water sources and the collective indices of dental fluorosis which indicate fluoride exposure at the community level. Methods: A descriptive study was carried out from two sources of information: the drinking water quality surveillance information subsystem (SIVICAP) and the public health surveillance system (Sivigila). The analyzes were performed from 2012 to 2018, weighting the risks for exposure to fluoride in water, to determine the following risk levels: no risk, dental fluorosis risk and risk for skeletal fluorosis. The collective dental fluorosis index (ICF) was calculated, the results were represented on geographical maps. Results: the departments of Nariño, Boyacá, Quindío, Valle del Cauca and Cundinamarca presented the highest number of water samples (60.5%). 14 municipalities had concentrations above 4 ppm, and 10 municipalities had concentrations between 1.01 and 4 ppm. Sentinel surveillance of fluoride exposure showed that three municipalities presented ICF> 3, meaning a very serious risk. Regarding serious risk, 52 municipalities from 21 departments were found, mainly in the Andean and Caribbean region. Nariño was the department with the highest number of municipalities at serious risk. Conclusions: environmental risks in water and biological risks were identified due to high collective indices of dental fluorosis, which are spatially located in the Andean region. The risks in water can be explained because in this region water quality surveillance is carried out more frequently.

RESUMEN

In Colombia, the inhabitants of the Mojana region have historically been subjected to high levels of environmental and occupational exposure to mercury; however, there are few robust data on the magnitude of this exposure and associated factors. This study aimed to describe the levels of mercury in the workers and inhabitants in this region, and to identify the main sociodemographic and occupational factors that are associated with this exposure. A cross-sectional study was conducted, in which mercury levels were determined in biological samples (blood, urine, hair) from 1119 people in the Mojana region. A questionnaire was also administered, which was adapted from the Global Mercury Assessment. Linear regression models were adjusted for the natural logarithm of mercury levels in blood, urine, and hair, using the factors that were explored as independent variables. The study reports high mercury levels in 35.0% of blood samples (95% CI 31.9⁻38.1%), 28.8% (95% CI 24.9⁻32.8%) of urine samples, and 56.3% (95% CI 53.1⁻59.5%) of hair samples. The reported source of water for consumption was associated with high levels of mercury (p-value < 0.05). We provide evidence of high levels of mercury exposure for the population in the Mojana region.
