Avaliação da qualidade do ar sobre a ética da deliberação normativa no município de Itabira (MG), quanto ao material particulado

Abstract

The city of Itabira, Minas Gerais, has in its territory the largest complex of open pit mining in the world. Much of this is located close to residential areas of the city. Which creates discomfort and risk factors to the population because of the amount of particulate matter in the atmosphere inherent in mining activity, which can affect human health in several ways. This particulate matter (PM) is formed by mechanical breakdown of the ore and ground handling machinery and equipment and heavy traffic in front of mines. The pacemaker is divided into two parameters to determine the concentration of particulate matter in the air: total suspended particles (PTS) and inhalable particles smaller than 10 m (PM10). This study evaluates the framework of the city of Itabira for Particulate Matter, adopting the Normative Deliberation CODEMA 01/2007 regulating norms and standards for air quality in the city. It is estimated that adoption of Secondary Standards indices of air quality contributes to better living conditions for the population. Thus, link air pollution and the incidence of respiratory diseases in the city, because the deleterious effects ranging from discomfort to death. Air pollution is a reality in Itabira, research shows that dust levels are close to those measured in large urban centers. It appears that after the approval of DN in Itabira the emission rates of particulates reduced considerably. Note that after starting the discussion for the approval of DN, mitigation measures for particulate control, made by the largest mining town, like sprinkling water in the mines, became more consistent and effective. It is expected that this standard into force reduction of the rates of concentration of pollutants in the atmosphere, and therefore, better air quality, reducing the incidence of respiratory and cardiovascular diseases in the city.
