[Limitations of the Water Quality Risk Index as an estimator of quality for human consumption]. / Limitaciones del IRCA como estimador de calidad del agua para consumo humano.

OBJECTIVE: To analyze the results of the Water Quality Risk Index (IRCA) in the 116 municipalities of the department of Cundinamarca, between 2007 and 2013. MATERIALS AND METHODS: Information collected from the 116 municipalities of the department of Cundinamarca, selected and classified according to the percentage data retrieved by IRCA. RESULTS: A decrease of the annual IRCA average is observed, which reflects an improvement of the water quality delivered in the department. However, 26.7% of the municipalities do not report information from their rural areas, and 56.9% of the municipalities report IRCA figures over 5, which means that even though they are at low risk, they receive water unfit for human consumption. CONCLUSIONS: A new weighting method for the parameters evaluated with the IRCA is proposed to make this index more representative of the risk to health. In addition, future studies should carry out a thorough statistical analysis on the size of the sample that allows the obtained results to be reliable for decision makers to improve the quality of drinking water.

OBJETIVO: Analizar los resultados del Índice de Riesgo de la Calidad del Agua para Consumo Humano (IRCA) para los 116 municipios del Departamento de Cundinamarca, del año 2007 a 2013. MATERIALES Y MÉTODOS: Información recolectada de los 116 municipios del Departamento de Cundinamarca, seleccionados y clasificados en función de los datos porcentuales del IRCA. RESULTADOS: Se observa una disminución del promedio anual del IRCA, lo cual refleja un mejoramiento de la calidad del agua entregada en el departamento; sin embargo, un 26,7% de municipios no reportan información de la zona rural y un 56,9% de los municipios reportan un IRCA superior a 5, que aunque se ubican en Riesgo Bajo, son un agua no apta para consumo humano. CONCLUSIONES: Se propone una nueva ponderación de los parámetros evaluados en el IRCA, con el fin de permitir que este índice sea más representativo del riesgo a la salud y, como estudios futuros un análisis estadístico concienzudo sobre el tamaño de la muestra que permita que los resultados obtenidos sean confiables para los tomadores de decisiones sobre el mejoramiento de la calidad del agua potable.

RESUMEN Objetivos Comparar la percepción sobre calidad de vida y situación ambiental, en municipios próximos y distantes de la actividad minero industrial del Departamento de Boyacá. Método Estudio epidemiológico transversal. Los municipios próximos al área de influencia fueron agrupados en zonas identificadas como 1 y 2, y los municipios distantes como zona 0. Se realizó un muestreo aleatorio simple, multietápico, por conglomerados. Se determinó una muestra de 1 117 hogares y la unidad de análisis fue la familia. Para medir la calidad de vida y percepción de salud se utilizó el instrumento WHOQOL-BREF. Se calcularon distribuciones de frecuencia, diferencias entre variables y comparaciones entre variables cualitativas y cuantitativas. Se realizaron análisis univariados y bivariados. Resultados La calificación de la calidad de vida y satisfacción con la salud es mayor en la zona 0. Las medias calculadas para los cuatro dominios del cuestionario, por municipios, muestra que Ramiriquí presenta los rangos intercuartílicos más elevados. La percepción de calidad de vida y salud disminuye a medida que aumenta la edad y se presentan resultados menos satisfactorios entre las mujeres. En las zonas 1 y 2, el medio ambiente del municipio se calificó como "muy malo" y la situación ambiental de su municipio sin ninguna mejora en los últimos cinco años Conclusión Las comunidades próximas a actividades minero-industriales, reportan una peor percepción de salud, mayor preocupación ante el riesgo a la exposición y no consideran que dicha actividad aporte mayores beneficios para su calidad de vida.(AU)

ABSTRACT Objective To compare the life quality perception and environmental situation, in nearby and distant towns from the mining industry of the Boyacá Department of Colombia Method Cross-sectional study. The towns near of influence area were grouped into zones 1 and 2, and distant towns as zone 0. Conglomerates carried out a simple, multistage, random sampling. A sample of 1,117 households was determined and the unit of analysis was the family. To measure the quality of life and health perception, the WHOQOL-BREF instrument was used. Frequency distributions and comparisons between qualitative and quantitative variables were calculated. Univariate and bivariate analyzes were performed. Results The life quality perception and satisfaction with health was greater in zone 0. The means calculated for the four domains of the questionnaire, by towns, shows that Ramiriquí has the highest interquartile ranges. The life quality perception decreases in women and with increasing age. In zones 1 & 2, the environment was described as "very bad" and without any improvement at the last five years. Conclusion Communities close to mining-industrial activities report a worse perception of health, greater concern about the risk of exposure and do not consider that mining industry provides greater benefits for their quality of life.(AU)

RESUMEN Objetivo Proponer un prototipo de sistema de tratamiento de agua para zonas rurales colombianas. Materiales y Métodos El prototipo consta de cuatro compartimientos en los cuales se adelantan procesos de clarificación del agua con piedra de alumbre y filtración, utilizando materiales granulares como: arenas de distinta granulometría, piedra pómez, carbón activado y gravilla. El agua problema se emuló siguiendo las características del agua encontrada en la zona rural del país y su monitoreo se realizó siguiendo la normatividad vigente en Colombia. Resultados Hubo reducción en coliformes fecales y totales del 99,9 %, turbiedad del 98 % y color del 83 %. En todos los casos los registros obtenidos permiten catalogar el agua tratada como apta para el consumo humano. El pH presentó un ligero aumento debido a la presencia de piedra pómez y otras calizas en el material filtrante, pero el valor medido, está dentro del límite máximo aceptado para agua potable. Conclusiones El sistema de tratamiento (purificación) evaluado en el presente estudio, produjo un agua apta para consumo humano a partir de agua con características promedio de zonas rurales semi-templadas del país. La tecnología propuesta es de fácil adaptación y difusión, y permite el control de enfermedades de origen hídrico en zonas desprovistas de sistemas de acueducto.(AU)

ABSTRACT Objective Propose a prototype system for safe water treatment in Colombian rural areas. Materials and Methods The prototype consists of four chambers working on a water -clarification process using alum stone, also working on a filtration processes using granular materials such as different grain sizes of sand, pumice stone, activated carbon and gravel. The water problem was emulated based on the average water features found in the countryside and its monitoring mechanism tracked the current regulations in Colombia. Results There was a reduction of the fecal and total coliform of the 99.9 %, a reduction of the 98 % of turbidity, and of an 83 % of color. In all the cases, the records obtained enable to catalog the treated water as fit for human consumption. The pH, presented a slight increment due to the presence of pumice and other limestone in the filter material, but the measured value was included under the upper limit accepted for potable water. Conclusions The treatment (purification) system evaluated in this study produced suitable water for human consumption obtained from countryside average water. The proposed technology is easy for adoption and diffusion and contributes to prevent water-borne diseases in areas without water systems.(AU)

Análisis multidimensional de las capacidades en salud ambiental del Ministerio de Ambiente y Desarrollo Sostenible en Colombia / Multidimensional analysis of environmental health capabilities in the Ministry of Environment and Sustainable Development in Colombia

RESUMEN Objetivos Realizar una aproximación al análisis multidimensional de las capacidades funcionales en salud ambiental del Ministerio de Ambiente y Desarrollo Sostenible, con base en el modelo del PNUD de interacciones entre problemas centrales y capacidades funcionales. Método Se utilizaron como fuentes de información los resultados institucionales obtenidos por medio de encuestas, b) información de fuentes secundarias, proveniente de las CAR y las autoridades ambientales, sobre las políticas, estrategias, planes de acción, planes de gestión ambiental regional - PGAR, normativas, actividades y rendición de cuentas. Resultados La consolidación de los resultados institucionales, con respecto a los problemas centrales y capacidades, muestran una heterogeneidad importante. Conclusión El liderazgo público y el empoderamiento social, constituyen un círculo virtuoso que permite fortalecer las capacidades en proyectos de alto interés social. En el marco de este encadenamiento es posible fortalecer las otras capacidades como el logro de compromisos y las de tipo institucional y técnico (diseño de políticas, implementación, evaluación, etc.). Se presentan tres alternativas que permiten la implementación de capacidades en salud ambiental.(AU)

ABSTRACT Objectives To approach the multidimensional analysis of functional capacities in environmental health in the Ministry of Environment and Sustainable Development, based on the UNDP model of interactions between central problems and functional capabilities. Method Individual institutional results obtained through surveys and information from secondary sources, CAR (Autonomous Regional Corporations) and environmental authorities on policies, strategies, action plans, regional environmental management plans, regulations, activities, and accountabilities related to environmental health during the period 2012-2015 were used as sources of information. Results The consolidation of results per corporation about core issues and functional capabilities, in terms of the level of response, shows a significant heterogeneity. Conclusions Public leadership and social empowerment constitute a virtuous circle that allows strengthening capacities in projects of high social interest. Moreover, other capacities such as achieving commitments and institutional and technical capacities (policy design, implementation, evaluation, etc.) can be strengthened as well. Three alternatives for environmental health capabilities implementation have been proposed.(AU)

Enfermedades transmitidas por el agua y saneamiento básico en Colombia / Waterborne diseases and basic sanitation in Colombia

RESUMEN Objetivo Analizar la relación de la cobertura de alcantarillado y tratamiento de aguas residuales con el comportamiento de las enfermedades de origen hídrico. Métodos Se realizó un estudio descriptivo de tipo retrospectivo, utilizando fuentes secundarias (revisión documental e información de bases de datos disponibles) sobre el comportamiento de la cobertura en saneamiento básico, tratamiento de aguas residuales domésticas en el país y la prevalencia de enfermedades relacionadas con la contaminación hídrica en el periodo 2008 a 2014. Resultados El país ha invertido en la puesta en marcha de sistemas de tratamiento de aguas residuales del 2011 al primer semestre de 2013, 1.100 millones de dólares, sin embargo la incidencia de enfermedades de origen hídrico como enfermedad diarreica aguda EDA, enfermedades transmitidas por alimentos ETA y fiebre tifoidea y paratifoidea, no han disminuido en el periodo 2008 a 2014, sólo la hepatitis A, ha registrado disminución. Discusión Se reconoce que la inversión en sistemas de acueducto y alcantarillado es relevante para el mejoramiento de las condiciones sanitarias de la población y para la disminución en la incidencia y la prevalencia de diversas alteraciones del estado de salud, sin embargo es necesario atender otros aspectos, tales como la educación en salud y el empoderamiento social, con el fin de avanzar en la creación de capacidades para afrontar esta problemática de manera más eficiente.(AU)

ABSTRACT Objective To analyze the relationship of sewerage coverage and wastewater treatment with waterborne disease behaviour. Methods A descriptive retrospective study was conducted using secondary sources (document review and information available in databases) about basic sanitation coverage, treatment of domestic sewage in the country and the prevalence of waterborne diseases during the period 2008-2014. Results The country invested USD 1,100 million in the implementation of wastewater treatment systems from 2011 until the first half of 2013. However, the incidence of waterborne diseases, such as acute diarrheal disease, foodborne diseases and typhoid and paratyphoid fever did not decrease during the period 2008-2014; only hepatitis A registered a decrease. Discussion Investment in water supply and sewerage systems is relevant to improve health conditions of the population and to reduce the incidence and prevalence of various health conditions; however, it is necessary to address other aspects such as health education and social empowerment to address this problem more efficiently.(AU)

Identificación de capacidades en salud ambiental de las autoridades ambientales en Colombia / Identification of capacities in environmental health from environmental authorities in Colombia

Objetivos Elaborar un diagnóstico rápido de capacidades de las autoridades ambientales y el Ministerio de Ambiente y Desarrollo Sostenible para asumir su rol en salud ambiental con base en el modelo de capacidades del Programa de las Naciones Unidas para el Desarrollo-PNUD. Método Se utilizaron los métodos de revisión documental, entrevista dirigida en aspectos clave y una encuesta comentada. Se seleccionaron 84 entidades a las cuales se les aplicó la encuesta de manera personalizada. Se obtuvo información completa de 76 instituciones. Resultados La valoración de favorabilidad del entorno se encontró entre las categorías aceptable y poco favorable, las capacidades en gestión del conocimiento se observaron precarias y la valoración de capacidades funcionales se reportó entre adecuadas o aceptables. La valoración de capacidades específicas tuvo una valoración de deficientes o apenas aceptables. Conclusión Se apreciaron dos problemas importantes: a. Las autoridades ambientales no conciben ni ponen en práctica estas capacidades desde el modelo del PNUD, sino desde el modelo convencional del Ministerio de Ambiente y Desarrollo Sostenible, y; b. Las autoridades ambientales muestran un nivel bajo de incorporación de las políticas de salud ambiental en su campo de acción específico.(AU)

Objectives To diagnose the capabilities that environmental authorities and the Ministry of Environment and Sustainable Development have to assume their role in environmental health, based on the capacity model of the United Nations Program for Development UNDP. Method Document review, interviews on key issues and a commented survey were conducted. 84 entities were selected for a tailored survey; complete information was obtained from 76 institutions. Results The valuation of environment favorability was within the acceptable and unfavorable categories; knowledge management capabilities were found to be precarious and assessment of functional capabilities ranged between appropriate and acceptable. The assessment of specific capabilities had a rating of poor or barely acceptable. Conclusions Two major problems were found: a. The environmental authorities do not conceive or implement these capabilities based on the UNDP model but on the conventional model of the Ministry of Environment, Housing and Territorial Development; b. Environmental authorities show an incipient level of incorporation of environmental health policies in their field of action.(AU)

Evaluación de condiciones ambientales: aire, agua y suelos en áreas de actividad minera en Boyacá, Colombia / Evaluation of environmental conditions: air, water and soil in areas of mining activity in Boyacá, Colombia

Objetivos Determinar concentraciones de PM10, mercurio y plomo en aire intramural de viviendas, en fuentes de agua y suelo de municipios aledaños a actividad minera. Método Se evaluaron 6 puntos en áreas de influencia y 2 en áreas control. Para las mediciones de aire intramural, se utilizaron los métodos NIOSH 600 (PM10), NIOSH 6009 (mercurio) y NIOSH 7300 (plomo). Para análisis de aguas se utilizó la Guía de monitoreo de vertimientos del IDEAM y, para análisis de suelos se utilizó la técnica de vapor frío (mercurio) y absorción atómica (plomo). Resultados En casi todas las viviendas seleccionadas, las concentraciones promedio de PM10 y mercurio en aire intramural superaron las normas aplicables de seguridad del aire, mientras que las concentraciones de plomo estuvieron por debajo. En todos los cuerpos de agua se encontraron concentraciones elevadas de plomo y en algunos puntos en las zonas mineras se encontraron niveles altos de hierro, mercurio y aluminio. En el monitoreo de suelos, las concentraciones de mercurio están por debajo del nivel de detección y, para plomo se observaron diferencias entre los puntos monitoreados. Conclusiones Se encontró concentración de varios contaminantes por encima de los valores aceptables. En las zonas evaluadas hay numerosas y diversas fuentes de contaminación de tal manera que no es posible individualizar las relaciones entre actividad minera y contaminación. Sin embargo, este tipo de estudios de corte aportan información puntual, útil para los agentes del sistema de salud ambiental e investigadores. Se sugiere instalar redes de monitoreo ambiental que permitan un seguimiento continuo.(AU)

Objectives To determine concentrations of PM10, mercury and lead in indoor air of homes, water sources and soil in municipalities near mining operations. Method 6 points were evaluated in areas of influence and 2 in control areas. For measurements of indoor air, we used the NIOSH 600 method (PM10), NIOSH 6009 (mercury) and NIOSH 7300 (lead). For water analysis we used the IDEAM Guide for monitoring discharges. For soil analysis, we used the cold vapor technique (mercury) and atomic absorption (lead). Results In almost all selected households, the average PM10 and mercury concentrations in indoor air exceeded applicable air quality standards. Concentrations of lead were below standard levels. In all water sources, high concentrations of lead were found and in some places within the mining areas, high levels of iron, aluminum and mercury were also found. In soil, mercury concentrations were below the detection level and for lead, differences between the monitored points were observed. Conclusions The results do not establish causal relationships between mining and concentration of these pollutants in the evaluated areas because of the multiplicity of sources in the area. However, such studies provide important information, useful to agents of the environmental health system and researchers. Installation of networks for environmental monitoring to obtain continuous reports is suggested.(AU)

Conclusions The results do not establish causal relationships between mining and concentration of these pollutants in the evaluated areas because of the multiplicity of sources in the area. However, such studies provide important information, useful to agents of the environmental health system and researchers. Installation of networks for environmental monitoring to obtain continuous reports is suggested.

Caracterización de la formación y desempeño del talento humano que labora en Salud Ambiental en Colombia / Characterization of the training and practice of human talent working in environmental health in Colombia

Objetivos Caracterizar las particularidades en la formación, ejercicio y desempeño del talento humano que labora en salud ambiental en Colombia. Método Revisión documental y de bases de datos, encuestas y entrevistas semiestructuradas. Resultados Aproximadamente el 70 % de los profesionales que laboran en el área de salud ambiental han sido formados en administración en salud, ingeniería de alimentos, ingeniería ambiental, ingeniería sanitaria, medicina veterinaria y química farmacéutica. El 63 % de los tecnólogos pertenecen a tecnología en saneamiento ambiental. Solo un 20 % de las instituciones educativas encuestadas aplica el enfoque por competencias para la formación de sus estudiantes y la identificación de características ocupacionales en el mercado laboral sólo se utiliza en el nivel de pregrado como un criterio de análisis y diseño académico. El 20% de las instituciones educativas identifica tendencias educativas nacionales y/o internacionales en salud ambiental como insumo de sus programas. En el ejercicio prospectivo se identificaron los siguientes temas para fortalecer: identificación, medición y control de factores de riesgo, formas de trabajo interdisciplinario entre las ciencias naturales, sociales y de salud, medidas preventivas y de protección ambiental y concepto de ambiente (natural, social y cultural). Conclusión El talento humano que actualmente labora en salud ambiental en el país está concentrado en actividades de atención primaria (inspección, vigilancia y control) y existe una gran dispersión en los procesos misionales y en las competencias tanto en los profesionales como en los tecnólogos. Se aprecia desarticulación entre el sector ambiental y el sector educativo.(AU)

Objectives To characterize the peculiarities in the training, exercise, and performance of human talent working in environmental health in Colombia. Method Documentary and database reviews. Surveys and semi-structured interviews. Results Approximately 70 % of professionals in the area of environmental health work in health management, food engineering, environmental engineering, sanitary engineering, veterinary medicine, and pharmaceutical chemistry. 63 % of technologists belong to the field of sanitation technology. Only 20 % of surveyed educational institutions apply the competence approach to training to their students and the identification of occupational characteristics in the labor market is only used at the undergraduate level as a criterion of academic analysis and design. Only 20 % of educational institutions identify educational trends in Colombian and or international environmental health as a contribution to their programs. In prospective practices, the following topics to be strengthened were identified: risk factor identfication, measurement, and control; design and implementation of mechanisms for controlling environmental risks; forms of interdisciplinary work between the natural, social and health sciences; preventative and environmental protection measures and the concept of environment (natural, social, and cultural). Conclusion The human talent currently working in environmental health in the country is concentrated in primary care activities (inspection, monitoring and control) and a large spread exists in mission processes and competences, both professionally and technologically. A lack of coordination between the environmental sector and the education sector can be observed. A great diversity exists among the profiles offered by the different educational programs related to environmental health.(AU)

[Economic assessment in health and environment from control of persistent organic pollutants in Colombia]. / Valoración económica en salud y medio ambiente del control de contaminantes orgánicos persistentes en Colombia.

Objective To estimate the economic benefits related to environment and health in the context of the implementation of the Stockholm Convention for the control of Persistent Organic Pollutants in the country. METHOD: The estimation was conducted based on two scenarios: non-compliance with the agreement and compliance with the Convention. Gross profit was derived from the difference in present value between the health and environmental costs that are assumed in each scenario. Results Gross profit by decreasing health costs arising from the implementation of the Convention was estimated at USD $ 511 and USD $ 501 million. By introducing variables such as management costs and agreement on potential benefits for access to international markets, the benefits to the country were estimated at between USD $1 631 and USD $ 3 118 million. Discussion Despite the economic benefits generated by lower expenditure on health for the Convention implementation, the costs associated with reducing pollutant emissions generated a negative balance, compensated only by the expectation of higher revenues for international market access. We consider this initial economic assessment an important contribution, but it should be reviewed to include valuation methodologies involving other social profitability variables and different scenarios for emerging technologies, new scientific knowledge about these pollutants, changes in legislation and / or changes in trade agreement conditions, among others.

[Cooperative learning for improving healthy housing conditions in Bogota: a case study]. / Aprendizaje cooperativo para forjar vivienda saludable en Bogotá: estudio de caso.

OBJECTIVE: This was a community-based effort at constructing an educational proposal orientated towards self-empowerment aimed at improving the target population's sanitary, housing and living conditions through cooperative learning. METHODS: A constructivist approach was adopted based on a programme called "Habitat community manger". The project involved working with fifteen families living in the Mochuelo Bajo barrio in Ciudad Bolívar in Bogotá, Colombia, for identifying the most relevant sanitary aspects for improving their homes and proposing a methodology and organisation for an educational proposal. RESULTS: Twenty-one poor housing-related epidemiological indicators were identified which formed the basis for defining specific problems and establishing a methodology for designing an educational proposal. DISCUSSION: The course which emerged from the cooperative learning experience was designed to promote the community's skills and education regarding health aimed at improving households' living conditions and ensuring a healthy environment which would allow them to develop an immediate habitat ensuring their own welfare and dignity.
