Determinación de las concentraciones de cromo contenidos en el material particulado respirable y determinación de las concentraciones de bioaerosoles en las localidades de los Mártires y Ciudad Bolívar en la ciudad de Bogotá D.C.

Abstract

The towns of Los Mártires and Ciudad Bolívar in the city of Bogotá, have a great industrial development due to their demographic expansion, where there is evidence of an increase in small and medium-sized SMEs, which may be possible contributors of traces of metals such as chromium in the air, likewise, biological pollutants generated by food industries or in the case of Ciudad Bolívar due to the presence of tanneries, may present a risk to the population's health

The results obtained showed that chromium concentrations were very low with respect to what was established by the WHO (0.25 µm). The microorganisms found in the air corresponded to 8 bacteria, 5 fungi and 2 yeasts, being S. Aureus and S. Epidermidis the Gram positive bacilli the bacteria of greatest interest given their medical relevance. Within the fungal organisms it was found that the genus Aspergillus was the most relevant since they colonize the airways.
