“…However, due to their location, some of these wetlands have experienced environmental disturbances in recent years due to increased urbanization and pollution generated by the surrounding communities 5 . This implies that anthropogenic activities such as wastewater dumping, waste material falling into water sources, urban construction, and other alterations and transformations of the ecosystem are significant factors contributing to the loss of water quality of these aquatic ecosystems 6 , 7 . Thus, quality refers to the measure of the chemical, physical, and biological characteristics of water that meet the conditions required by one or more biotic species for a specific use 8 .…”

Wetlands represent key ecosystems due to their remarkable biodiversity, ecological functions and multiple ecosystem services provided. In Colombia, there are 31,702 wetlands, 13 of which are in Bogotá, capital of the country. Despite the fundamental socioecological support of these aquatic ecosystems, a tremendous loss and degradation of these ecosystems has been observed due to anthropogenic perturbations. Therefore, the aim of this study was to describe the status of seven Bogotá wetlands with variable anthropogenic interventions by measuring organoleptic, physicochemical, and microbiological parameters, using commercial kits, highly sensitive equipment, and next-generation sequencing of the 16S- and 18S-rRNA genes. Our findings describe the status of seven wetlands with different anthropogenic burden in Bogotá-Colombia where physicochemical and microbiology signals of contamination were observed. Additionally, some profiles in the composition of the microbial communities, together with certain physicochemical characteristics, may represent an insight into the environmental dynamics, where Beta Proteobacteria such as Malikia represent a potential keystone in aquatic ecosystems impacted by wastewater effluent discharges; the presence of nitrates and phosphates explain the abundance of bacteria capable of oxidizing these compounds, such as Polynucleobacter. Moreover, the presence of specific prokaryotic and eukaryotic organisms, such as Clostridium, Cryptococcus, Candida, and Naegleria, reported in one or more of the wetlands assessed here, could represent a possible pathogenic risk for human and animal health. This study performed a complete evaluation of seven Bogotá wetlands with different anthropogenic impacts for the first time, and our findings emphasize the importance of maintaining continuous monitoring of these water bodies given their remarkable ecological importance and potential spill-over of several pathogens to humans and animals.

Objetivo Determinar la asociación existente entre factores ambientales y sanitarios, y la prevalencia de afecciones respiratorias en los habitantes de las veredas El Sango, Romeral y Pastorcita del municipio de Guarne, Colombia, segundo semestre del año 2015.Materiales y Métodos El estudio fue de carácter descriptivo con análisis correlaciónales, en él se emplearon fuentes primarias de información, se diseñó una encuesta con preguntas cerradas. La población fue constituida por 493 habitantes, con edad ≥18 años. Se realizaron análisis descriptivos, bivariados con cálculos de prueba Chi 2 y Fischer, con RP y sus respectivos IC del 95%.Resultados Entre los más importantes, se encontró que el 6,5% de la población ha padecido en el último año, alguna afección respiratoria, las más frecuentes fueron: asma con 2,9% y EPOC con un 2,7%. Se encontraron asociaciones estadísticamente significativas entre padecer afecciones respiratorias y residir cerca de fábricas o industrias:RP 2,608 (IC 1,344-5,059) P<0,05; también se encontraron riesgos en personas que residen cerca de aguas negras o basureros: RP 2,333 (IC 1,278-4,257) P<0,05.Pudo encontrarse mayor prevalencia en personas cuyas casas tienen techos de barro, caña o esterilla: X2 3,214, P<0,05; así como vivir en la vereda Romeral: X2 7,032, P<0,05.Conclusiones La población de interés se encuentra expuesta a factores de contaminación ambiental (micro fábricas o industrias) y sanitaria (aguas negras y basureros) y que en efecto estos están asociados a la prevalencia de afecciones respiratorias en el sector.
