TL;DR: A review of the current situation and future challenges to be faced in mitigating the environmental and human effects of plastic particle pollution in aquatic, particularly estuarine, ecosystems is presented in this paper .

TL;DR: In this article, bottom surface sediment samples were collected in Guanabara bay using a van-Veen sampler and analyzed for grain size distribution and organic matter, which allowed a division of the bight into three sedimentary zones: a south, sand dominated zone of relatively high wave and current energy, a north zone characterized by very calm conditions and clay/mud deposition, and a central zone of mixed sedimentary characteristics.

TL;DR: In this article, the authors identified the group of clay minerals identified in the Guanabara Bay bottom sediments, i.e., Kaolinites, illites, and smectites.

TL;DR: In this paper, multiproxy analyses were performed on samples from a 490-cm-long sediment core collected at the coordinates 40°18′23′′W and 20°14′48′′S. The sediment core was dated to two depths: the oldest age was between 9396 and 9520 cal yr BP at a 480-cm depth, and the youngest age was from 7423 to 7511 cal yrBP at a 304cm depth.

TL;DR: In this paper, a 12.5m thick sedimentary section studied here represents the last 8111 years of lagoonal deposition and five sedimentary facies were identified: (1) subrounded sand facies (containing a gravel subfacies) which occur along the southern margin; (2) silty sand faces occurring at the transition from the margin to the lagoon center; (3) sandy silt faces and (4) silt/clayey silt facies which cover the calmer, central areas of the Lagoon; and (5
