Assessment of potential ecological risk by metals in Ilha Grande Bay (Southeast Brazil).

This study evaluates contamination and potential ecological risk in Ilha Grande Bay (BIG) in southeastern Brazil. To achieve these objectives, we analyzed physicochemical, sediment textural, and geochemical data from 134 stations distributed throughout the bay. The results reveal significant environmental degradation in the coastal areas of Paraty, Saco do Mamanguá, Angra dos Reis City, and Abraão Cove (at Ilha Grande island).

Future scenarios in the former oil capital: coastal flooding and social vulnerability in Macaé, RJ.

The accelerated urban growth in Macaé had important consequences on socio-spatial organization, especially about housing spaces that became increasingly difficult to be accessed by the low-income population. The most devalued lands, such as mangroves and floodplains, were occupied by the low-income population. The proposal highlighted in this project focuses directly on the problem of rising sea levels and flooding in the urban space of Macaé, which is of social interest.
