The objective of the present study was to investigate metal(loid)s in soils, in the trunk xylem sap and in the leaves of the Dipteryx alata plant located near the highway with high vehicle traffic in agricultural regions and near landfills, and to assess the transfer of metal(loid)s from soil to plant and possible health risk assessment. Trunk xylem sap, leaves and soil samples were collected at three sites near the highway. The analysis of trace elements was carried out using inductively coupled plasma optical emission spectroscopy (ICP OES). In the three soil sampling sites far from the highway edge, 15 elements were quantified. The concentrations of elements in the soil presented in greater proportions in the distance of 5 m in relation to 20 and 35 m. The metal(loid)s content in the study soil was higher than in other countries. The concentrations of Al, Cu, Fe, Mg, Mn, P, Se and Zn in the xylem sap were much higher than the leaves. The values of transfer factor of P, Mg and Mn from soil to the xylem sap and transfer factor of P from soil to leaf were greater than 1, indicating that the specie have a significant phytoremediation and phytoextraction potential. This plant has a tendency to accumulate As, Cd and Cr in its leaf tissues. The chronic hazard index (HI) values recorded in this study were above 1 for adults and adolescents. It is concluded that the soil, the trunk xylem sap and leaves of this plant are contaminated by heavy metals. Ingestion of the trunk xylem sap of this plant can cause toxicity in humans if ingested in large quantities and in the long term; therefore, its consumption should be avoided.

A deficiência visual é a deficiência mais prevalente no Brasil. Embora haja um incentivo por parte de políticas governamentais para que se amplie o acesso à educação, sabe-se que a adaptação de ambientes à estes indivíduos ainda é precária. Assim, o objetivo deste artigo é discorrer sobre a importância das pessoas com deficiência visual no ensino superior e as diferentes ferramentas que podem ser implantadas nestas instituições com o objetivo de ampliar a acessibilidade a estes locais. Realizou-se uma revisão simples de literatura, com busca nas bases de dados Scielo, Lilacs e Google Acadêmico. Estes indivíduos necessitam de um ensino superior adaptado para que se possibilite maior inclusão e aumento da autonomia. Destaca-se o uso de dispositivos móveis, a presença de pisos táteis, materiais em formato eletrônico, o preparo dos educadores para trabalhar com este público, bem como o treinamento prévio do deficiente visual para fazer uso destas ferramentas
