Análise das concentrações de dióxido de carbono em uma preservada da caatinga.

Abstract

Currently, one of the greatest difficulties faced by society is related to Climate Change, which intensified by human activities, has caused irreversible damage to the natural cycle of the climate system. Which has caused an increase in the emission of Greenhouse Gases (GHG's), as is the case with Carbon Dioxide (CO2) and thus intensifying the greenhouse effect and consequently increasing the temperature. The objective was to carry out an analysis of the carbon concentration in a preserved area of the Caatinga within the campus of CCTA / UFCG Pombal / PB, from November 2019 to March 2020. A portable instrument of direct reading was used, through of a nondispersive infrared sensor, model C02, for measuring carbon dioxide, air temperature and relative humidity, in the morning and afternoon shifts, between 9 am and 2 pm. It was possible to observe the contribution of vegetation to the carbon concentration. It was concluded that the concentrations of Carbon Dioxide were higher in the afternoon shift with higher temperatures, for the dry period.
