IMPACTS OF MINING AND STEEL INDUSTRIES ON CONCENTRATIONS OF PM10 AND SO2, IN THE REGION OF GRANDE VITÓRIA, ESPÍRITO SANTO, BRAZIL

Edson Zambon Monte

Abstract


This study aimed to verify the impacts of mining and steel industries on concentrations of particulate matter (PM10) and sulfur dioxide (SO2), in the Region of Grande Vitória (RGV), Espírito Santo, Brazil, using the Vector autoregressive/Vector error correction (VAR/VECM) method. The results showed that i) the concentrations of the pollutants PM10 and SO2 are significantly impacted by mining and steel industries, being the sectors represented in this study by the export of iron ore pellets and concentrates and other semi-manufactured products of iron/steel; ii) the influence of the mining and steel industries is higher on the pollutant SO2 than on PM10; and, iii) short-term estimates of the cointegration vector revealed that the short-term imbalances for PM10 concentrations are corrected more quickly than for SO2 concentrations.

Keywords
