Abstract

Heavy metals associated with the road sediment can impair the quality of air, soil and vegetation of environment when they are suspended by the wind and turbulence induced by the traffic. Additionally, they can affect the water quality of the river systems when they are transported by the runoff. The objective of this paper is to present a temporary assessment (daily) of the heavy metals (Pb-Cu) concentration associated with the road sediment of the localities of Fontibón and Barrios Unidos (Bogotá D.C., Colombia). The concentration was determined by flame atomic absorption spectrometry. Previously the samples were digested in a mixture of hydrochloric and nitric acid (3:1; aqua regia). The results show for the finest fraction of road sediment (≤ 63 µm), which is also the fraction with size closest to the potentially inhalable (≤ 10 µm), that the concentrations tend to increase in dry weather (Pb: 34%; Cu: 40%). The concentrations of Pb and Cu during this period are 1.59 and 5.30 times higher than the lowest limit value fixed by the administrations of Cataluña and Canada, respectively. The findings are a reference point for Colombia in order to publish legislation associated with this type of pollution (hazardous waste). [ABSTRACT FROM AUTHOR]

Abstract

This article gives account of the socio-demographic and epidemiological profile of the population located in Vereda Manuel Sur (Municipality of Ricaurte) and the neighborhoods Brisas del Bogota and La Victoria (Municipality of Girardot, Cundinamarca, Colombia), exposed to contamination by toxic-heavy metals from the waters of the Bogota River. The article is part of the results of the first phase of a four stage study -planned for execution from 2008 to 2010- for the implementation of promotional strategies in health that contribute to the generation of healthy lifestyles in the population located on the low alluvial plain of the Bogota River, which is exposed to contamination by mercury, lead and cadmium. An instrument for data gathering containing social, demographical and epidemiological variables was administered to 1,040 inhabitants whereof440 live in Vereda Manuel Sur, 237 live in the neighborhood La Victoria, and 363 live in the neighborhood Brisas del Bogota. It was found that prevalence is given by immunological, digestive and respiratory diseases. Among them, the incidence of respiratory and digestive diseases can be caused by environmental problems, weather changes, air contamination or untreated water consumption. [ABSTRACT FROM AUTHOR]
