“…The presence of microplastics near the coast is influenced by physical and chemical processes, including the transport of plastics by current and wind, as well as degradation by weathering (Fok et al 2017;Hartmann et al 2017;Zhang 2017;Yu et al 2018). Some studies revealed that sandy beaches may act as a temporary or permanent sink for microplastics (Lozoya et al 2016;Yu et al 2016). Plastics in beach sediments generally have a long residence time and can be fragmented due to UV irradiation and physical abrasion by waves (Veerasingam et al 2016).…”

Microplastics have become ubiquitous in the marine environment. Microplastics have been detected in many coastal environments and species, including commercial seafood. This triggers concern about potential economic impacts and the risks of dietary exposure, especially for coastal communities. However, data regarding the levels of microplastics in coastal seafood and their toxicological effects are still limited. Accordingly, the dietary risk is still poorly explored. This review summarizes and discusses recent scientific findings on (i) the presence of microplastics in coastal waters, (ii) the occurrence of microplastics in coastal seafood and the likelihood of trophic transfer, and (iii) the effects of microplastics on coastal fish and shellfish species. Human toxicity data are also reviewed, but the risks for human health are difficult to determine due to limited data. Based on available worldwide data, the estimation of microplastics intake through seafood consumption shows a huge variation. Additionally, a lack of standardized analytical methods complicates the comparison of results between studies and therefore seriously affects the reliability of risk assessments. It is concluded that more exposure and toxicity data are needed properly to assess human health risks of microplastics in coastal seafood, and the lack of data currently impede the derivation of a risk-based food safety standard. The pros and cons of an interim solution, i.e. setting a provisional action level, are being discussed.

First record of microplastics in two freshwater fish species (Iheringhthys labrosus and Astyanax lacustris) from the middle section of the Uruguay River, Brazil

Aim The aim was to analyze the incidence of microplastics in the diet of fish in the middle Uruguay River. Methods The present work analyzed the gastrointestinal content of two species: Astyanax lacustris and Iheringichthys labrosus. Results This study provides the first evidence of synthetic materials, such as fibres and plastics in the gastrointestinal tract of fish species in the Middle Uruguay River basin. A sample of sixty-one A. lacustris and twenty-nine I. labrosus were examined to highlight the ingestion of microplastics in the middle section of the Uruguay River in Brazil. In the A. lacustris, eleven fibres and two fragments were found in their gastrointestinal contents, corresponding to 18.1% of the specimens, while in the I. labrosus, twelve fibres and one fragment were found, corresponding to 34.5% of the specimens analyzed. Blue staining was also prevalent in the occurrence of microplastics. Conclusions These data are the first record of microplastics in this zone and represent a baseline for this contamination for future studies.

“…For example, the documented work by a group of researchers in Central Italy, findings in Japan, and results of South China Sea investigations, among others linked the source of litter in beach areas to sources from land [19,20,58]. Other recent works on anthropogenic marine debris in the coastal environment of Chile, on the plastics and microplastics on recreational beaches of Punta del Este in Uruguay and studies from South East Pacific and Columbia all confirmed that most of the abundant of litters found along the beach and coastal areas of the world are plastics generated from the land, with their daily quantity entering these areas being relatively unknown [17,[59][60][61]. However, the other researchers estimated the plastic litter being generated as wastes that end up in the coastal areas of Columbia reaching the "values of 1,075,294 kg day -1 " [17].…”

Beach litter constitutes one of the glaring signs of pollution in coastal landscape and environment. In this study, litter presence and composition were assessed for the five (5) sampling sites along the coastline in three (3) Administrative Regions (Regions 4, 5, and 6) in Guyana based on fieldwork carried out in January 2018. Survey of beach litters represents a fundamental, standard, and documented tool for monitoring pollution in a coastal environment and this method was used in evaluating, classifying, and quantifying the composition of beach litters along the five (5) sites aforementioned. This study showed that the litter contents varied considerable among the sampling sites. However, out of all the categories of beach litter items in all of the sample sites, plastic materials accounted for most of the litter followed by metal, paper/card, glass, wood fragments, clothing materials, organic materials, and pottery at 48.2%, 20.8%, 11.5%, 6.8%, 4.7%, 4.6%, 3.2%, and 0.2% respectively. The average grading of the beaches shows that none could be graded A (very good), without cleaning up of such areas of litter. Rosignol beach (Sample Site 3) and Georgetown beach (Sample Site 5) were the only beaches with average grade C (fair) while the other three (3) samples sites could only be graded D, very poor. This paper highlights the geographic distribution, pattern, and litter composition in the study areas. To meet the demands of the potential beach users for the purpose of coastal tourism and to benefit from the growing "sun, sea, and sand (3S)" industry, conscious and strategic Beach Litter Management and Monitoring, among other recommendations, is suggested in this study. KEYWORDS Litter; beach areas; coastal tourism; marine pollution. Marine/beach litter, here, is defined as "any persistent, manufactured or processed solid material discarded, disposed of, or abandoned in the marine and coastal environment" (CBD Technical Series, [34] cited in [35]. Survey of beach litter presence in all compartments of coastal environments, especially at intertidal coastal zone and beach areas [36]with the aim of qualifying, classifying, and quantifying the litter-is a very fundamental step in monitoring the weight of the litter [37] and it is a key factor in strategizing how to minimise the presence of this load in the coastal environment [38]. Guyana, a developing country, is conspicuously not one of the countries that benefitted significantly from over 23.8 million visitors to the Caribbean and the Southern America in 2015 [10].
