ANTUNES-SANTANA, Otacílio  e  IMANA-ENCINAS, José. Influence of a landfill in the city of Goiânia on the grouping of arboreal species of the Brazilian savanna. Kurú [online]. 2018, vol.15, n.37, pp.57-66.  Epub 12-Jul-2019. ISSN 2215-2504.  http://dx.doi.org/10.18845/rfmk.v15i37.3596.

The objective of this work was to show the influence of one municipal waste deposit of the city of Goiânia, capital of the state of Goiás - Brazil in the tree species grouping of the Brazilian savanna’s natural vegetation. The study area is located adjacent to the landfill. Laboratory tests were carried out to measure the soil and groundwater contamination. From the analysis of the canonical correspondence and the phytosociology it was concluded that the landfill directly influences the grouping of the arboreal species of the adjacent forest. Some tree species such as Alibertia macrophylla Schum., Eugenia dysenterica DC., Miconia albicans (Sw.) Triana and Virola sebifera Aubl., as they move away from the landfill area are modified and improved their ecological position on the vegetal community. Depending on the distance of the landfill, six chemical elements: acidity, dissolved oxygen, conductivity, total dissolved solids, sulphate and ammonium directly affected the behavior of the increase in the importance value index of the existing tree vegetation. These six elements showed an excessive presence in relation to the standards established by the Ministry of Health, the World Health Organization and the National Environment Council.
