CONCENTRACIÓN DEL MATERIAL PARTICULADO SEDIMENTABLE EN LA ZONA URBANA DE "LA TRONCAL", Y SU RELACION CON LAS ACTIVIDADES AGRICOLAS DE CAÑA DE AZUCAR.

Abstract

The burning of sugarcane crops is a common practice that has been carried out continuously for many years until today, so there is a perception that the sedimentable particulate material that is generated through them, their concentration harm the quality of the air can. This project seeks to evaluate the concentration of sedimentable particulate material in the urban area and from this identify what relationship it has with agricultural activities, taking into account the variables of harvests, total and monthly burned hectares. For the study, 4 survey sites are required, located within the urban area. In addition, the methodology referred to in the "Standard method ASTM D-1739 for collection and measurement of dust fall" was used, the monitoring was carried out during the months of August to November 2021. The present work shows reference baseline values to concentrations in the air, with respect to sedimentable particulate material, in which an average concentration of 1.30 mg/cm2 was presented, however, in none of the test sites was it found that the permissible concentration limits of 1 mg/cm2 for 30 days, set forth in the Ecuadorian quality standard, were exceeded, but a direct relationship was obtained that reflected that the greater the burning of the crops, the greater the concentration from the particulate material from surrounding areas.
