CO2 (dióxido de carbono) e suas interações no meio ambiente: Concentração de CO2 como indicador de qualidade ambiental em diferentes locais do munícipio de Laranjal do Jari-AP.

Abstract

This present work aiming of carrying out measurement and analyzes of CO2 concentrations in ppm (parts per million) in the municipality of Laranjal do Jari in the south of the State of Amapá.With the measurements of CO2 concentrations obtained in the city, the regions were classified according to the CO2 concentration, noting that the concentrations can influence the air quality in the region. With the aid of the CO2 detector equipment Air Detector, model number H8, voltage of 5v, battery of 1200mAh and with measurement limits ranging from a minimum of 400 ppm to a maximum of 5000 ppm of CO2 concentrations with an error of 2ppm, measurements were carried out. in several predetermined areas in the municipality. During an established period of 10 consecutive days, measurements were taken at the points of Beira (center), Cais de Laranjal do Jari, IFAP (district of Cajari), BR156 (Nazaré Mineiro) and Bairro Agreste. The results of the CO2 concentrations in ppm of all the predetermined places were described in tables and graphs, containing the information of date, hour, ppm and temperature. An analysis showed that the results obtained from the CO2 concentrations in the graphs and tables of the studied places, describe the measurements within the minimum range of 400 ppm to the maximum of 460 ppm, within the levels of CO2 concentrations of 1000 ppm according to the Resolution RE/ANVISA nº 176, of October 24, 2000. Laranjal do Jari still has pure air in its essence and this work leaves a warning for periodic measurements to be continued to avoid further damage to the environment and the local population in the future.
