Arraial do Cabo, RJ, Brazil, is known as the diving capital due to its clear waters and great biodiversity, a consequence of the upwelling phenomenon. This feature attracts tourists tripling their population during holidays, causing increase in the amount of debris on beaches and waters endangering marine biodiversity. To evaluate the amount of solid waste found on beaches in two different holiday period, eight people in each beach collected macrodebris (≥2 cm) in a transect covering an 20 m wide area, during 20 min, in winter/2015 and summer/2017. The materials were weighed, quantified and characterized. In the summer, when the number of tourists is greater, a larger total amount of waste in units were found. Plastic and cigarette butts were the most abundant. The results show that the city does not have adequate planning to receive a large amount of tourists, being vulnerable to socioeconomic and environmental damages.

Plastics are ubiquitous in the environment, causing pollution recognized as a marker of the Anthropocene era. All environments are affected, including coastal and river ecosystems, where studies have shown that plastic waste contamination is proportional to the level of urbanization. This study, to our knowledge, is the first in France to investigate the spatial and temporal distribution of litter across the Land-Sea continuum, using debris classifications based on OSPAR (Oslo-Paris Convention 1992) and EPR (Extended Producer Responsibility).

Islands are particularly vulnerable to storms and hurricanes, which can cause severe environmental, economic, and social impacts, including the accumulation of waste in marine ecosystems. In November 2020, Hurricane Iota struck the islands of Providencia and Santa Catalina in the Seaflower Biosphere Reserve, Colombia. This study assesses the distribution, composition, and sources of marine litter after the hurricane, focusing on variations observed across coastal ecosystems such as beaches, mangroves, and coral reefs.

Coastal regions, including beaches, constitute major tourism assets. Concurrently, beaches are hotspots for microplastic generation, and accumulated beached litter substantially influences future microplastic abundance in the marine environment. Although the stock of plastic litter on beaches has been estimated in previous studies, knowledge gaps exist with regard to the amount of annually generated litter by beach users and the absence of litter generation rate (LGR) in g/person/h or items/person/h.

This work shows that the plastic debris accumulated along with stranded Sargassum biomass in Guadeloupe's beaches contains different forms of arsenic. Results from synchrotron nano X-ray Fluorescence (nanoXRF) and nano X-ray Absorption Near Edge Structure (nanoXANES) show that arsenate (As(V) in a tetrahedral coordination) present in seawater is complexed in the algae cell walls in an octahedral As(V) form, which is subsequently reduced to As(III) within the algae. Inorganic As(III) is either excreted or may undergo methylation and/or binding to glutathione, which is then stored in the algal cells or excreted.

This paper describes the microplastic problems on five sandy beaches along the Skikda coastline (southwestern Mediterranean, northeastern Algeria), defining their magnitudes, spatial-temporal distributions, shapes, polymer types, impacts, and potential sources. The data presented in this study were collected during two field surveys in May (spring) and September (autumn/fall) of 2019. Overall, the average abundance of microplastics across all beaches was 6174 items/m in spring and 6183 items/m in autumn, representing the highest level of MPs ever reported in Algeria.
