TL;DR: In this paper, surface and long core sediments of the Guanabara Bay (Rio de Janeiro, Brazil) were investigated for mercury (Hg) and the main, but not only, input of Hg into the Bay's waters is known to be a Chlor-Alkali Plant (CAP) located in the Acari-Sao Joao de Meriti River system, on the northwestern side of the Bay.

TL;DR: In this paper, the authors investigated saltwater contamination, sea level rise and morphological changes recently performed in these two coastal areas and concluded that these factors expose coastal areas to morpho-hydro-geological hazards, such as soil desertification, frequency and degree of flooding, littoral erosion, and the silting of river mouths and channels.

TL;DR: The study highlights the worsening of environmental conditions since 2000 and those areas of the bay in need of a priority recovery and taxa capable of differentiating the presence of pollutants of different sources.

TL;DR: The contribution of the geological and morphological setting to the worsening or contrast of land subsidence and saltwater intrusion was pointed out in three areas located south of the Venice Lagoon (Italy): the littoral stretch of Chioggia, the southern lagoon margin (Punta Gorzone) and an inland sector of the lagoon drainage basin (the Zennare Basin) as mentioned in this paper.

TL;DR: The Lagoon of Venice was formed during the Late Holocene transgression and anthropogenic remains are common within its sedimentary sequences as mentioned in this paper, which indicate conditions characteristic of present-day salt marshes.
