Analysis of the occurrence of microplastics in beach sand on the Brazilian coast

Science of The Total Environment, 2021
The occurrence of microplastics in coastal areas is a growing concern due to the increase in plastic waste pollution in recent decades. This study had as objective to evaluate the occurrence of microplastics in Brazilian beach sand, using a simple and fast methodology.

Sambaquis (shell mounds) of the Brazilian coast

Quaternary International, 2011
Abstract The Brazilian shell mounds called sambaquis have been well known since the 16th century when clergy, travelers, and members of the colonial administration wrote the first narratives of Portuguese America. However, it was only during the second quarter of the 19th century that, under the orders of the Imperial Government, the first scientific

An overview of longshore sediment transport on the Brazilian coast

Regional Studies in Marine Science, 2020
Abstract The present study investigates the wave behavior and the longshore sediment transport rate on the Brazilian continental shelf, using a computational model and four different formulations, for the period between 1979–2015. The average significant wave height is substantially variable along the study region, with the largest values occurring ...

A case of envenoming by Portuguese man-o'war from the Brazilian coast

Toxicon, 1995
This is an individual case report on envenoming caused by the cnidarian Portuguese man-of-war. The reported local reactions and the clinical symptoms are similar to those already known for Portuguese man-of-war envenoming. As far as we know it is the first clinical case documented for the Brazilian shores.

The earliest shellmounds of the central-south Brazilian coast

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004
Abstract This paper presents a new date for one of the oldest shellmounds of the central-south Brazilian coast. This date seems to confirm three previous results obtained from two other shellmounds in the same region and formerly seen as unreliable by the archaeological community.

Variability of Mangrove Ecosystems along the Brazilian Coast

Estuaries, 1990
Brazilian mangroves extend from 4°30′N to 28°30′S, varying greatly in growth form, species distribution patterns, and stand structure, in spite of a limited floristic diversity. We divided the Brazilian coastline into eight units, within which physiographic and climatic conditions are relatively uniform, and described mangrove occurrence, species ...

Solid waste ingestion by marine megafauna on Southeast Brazilian coast

Marine Pollution Bulletin, 2023
The disparities in the ecology and behavior of marine megafauna may influence their susceptibility to solid waste ingestion; however, this relationship has been underestimated along the Brazilian coast. We analyzed a dataset of 7261 marine megafauna (45 species) necropsied to investigate the influence of their foraging strategies on solid waste ...

An Outline of Marine Toxinology Studies in the Brazilian coast

Comments on Toxicology, 2003
Over the last 20 years, our group has collected different species of marine organisms occurring in the Brazilian coastline. The pharmacological approach is the evaluation of effects of organic extracts, or purified and isolated compounds in laboratory animals, organs, tissues, and cells to define the profile of biological activity and the mechanisms of

Macrolitter pollution in beaches and mangroves on the Brazilian Amazon coast

Marine Pollution Bulletin
Macrolitter pollution risks coastal ecosystems, impacting biodiversity and human activities. This study compares macrolitter composition and abundance in beach and mangrove environments on the Ajuruteua Peninsula, Pará, Brazilian Amazon, an area designated as an Environmental Protection Area (APA).
