ESPÉCIES VEGETAIS TÓXICAS DA FAMÍLIA APOCYNACEAE: UMA ANÁLISE SOBRE A DISTRIBUIÇÃO E OS CASOS DE INTOXICAÇÃO REGISTRADOS EM ARAGUAÍNA, TO

Abstract

The plants possess toxic substances, for their natural properties, physical, chemical or physical-chemical,capable of causing metabolic change, these are known as intoxication. Children are more susceptible to intoxication, because the fact of always playing in their backyards end up ingesting plants that can often be toxic. The main objectives of this research were to realize a toxic species census from plants family Apocynaceae and a survey of the intoxication cases caused by these plants, which were provoked accidentally or not, between january/2009 until december/2014 in 29 Araguaína neighborhoods. Furthermore, maps were listed and consulted to identify the regions and neighborhoods with their own streets and avenues hence to analyze the urban afforestation. Next, the census of the toxic plant species was realized in the 30 neighborhoods. The results obtained shown 24 exemplars of Allamanda catartica and 28 exemplars of Thevetia peruviana(Pers. K. Schum) that correspond to 66,67% of all the cases analyzed, which shown a randomic distribution, in the neighborhoods. The species mentioned above were both registered together in the following neighborhoods: Loteamento Martins Jorge, Sector Urbano, Sectors Santa Mônica and Tereza Hilário. There was no intoxication case from specie Apocynaceae recorded in the city of Araguaína between january/2009 until december/2014.
