Plan de Manejo Ambiental de Ruido en Aserraderos y Carpinterías en la Ciudad de Riobamba

Abstract

This study was based on the monitoring of noise levels in carpentry and sawmills in the city of Riobamba, to identify noise levels that may affect the people who live around them and the personnel who work in them in order to propose an environmental noise management plan to the municipality of this city. The measurements were taken from March to June 2008. Previously, these establishments were identified and zoned, taking a statistical sample of 35, distributed in 5 parishes of the city. Methods and techniques described in Book VI, Annex 5, of the Environmental Legislation of Ecuador were used, using a type 2 sound level meter. The source noise levels in the carpentry shops fluctuated between 60.09 dBA and 91.21 dBA, while in the machines fluctuated between 76.08 dBA and 95.12 dBA. In the sawmills, the source noise level was between 71.31 dBA and 93.35 dBA, and in the machines between 77.30 dBA and 95.67 dBA, exceeding the permissible levels. The management plan proposes applying preventive measures to mitigate the impacts caused by the high noise levels generated by these activities, applying environmental education policies, making changes to the internal and external structure of the premises, isolating noise, developing noise decontamination and land use control plans, etc. The conclusion is that there is moderate noise pollution and it is therefore advisable to apply the environmental management plan proposed for the municipality of Riobamba.
