ROJAS VITERI, Luis  e  GARCIA PRIETO, Amalia. Caracterización de la exposición a polvo orgánico en el área de producción de alimento balanceado y granjas avícolas en la empresa “Megaves Cía. Ltda.”. Siembra [online]. 2015, vol.2, n.1, pp.44-50. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v2i1.129.

This study defined exposure to organic dust of workers in the area of balanced diets production and poultry farms of the company Megaves. This was a descriptive and cross-sectional study, in which the exposure to total organic dust (inhalable fraction) was compared to the permissible limits of Instituto Nacional de Seguridad e Higiene en el Trabajo (INSHT) from Spain. A hygienic survey was applied with the aim of characterizing the risk determinants. EVM3 was used to measure dust and to characterize the exposure. It was configured to a flow of 1.7 l/minute, and with an active uptake to dust with particle size lower than 10 microns. The measurements were developed for the 75% of the work day. The samples were weigthed according to the technical standard of the INSHT MTA/MA-014/A88 “determination of matter (total and inhalable fraction) particulate in air - gravimetric method”. The dust concentrations found were below the permissible limit of 4 mg/m3, so that the exposure to particulate matter is not a real risk to the health of workers in the company under study.
