“…MPs collected from beaches in Guadeloupe shared common characteristics with MPs collected from other beaches (Mazariegos-Ortíz et al, 2020;Pannetier et al, 2019;Rangel-Buitrago et al, 2021) with a majority of fragments (>98%) mainly composed of PE (75-80%) and PP (20-25%) and chemical analyses revealed the presence of sorbed pollutants. Previous studies reported that PE is the most abundant polymer found in plastic litter, followed by PP and polystyrene (Cheang et al, 2018;Fossi et al, 2017;Hidalgo-Ruz et al, 2012;Karthik et al, 2018), and are the predominant polymers of MPs collected on beaches over the world (Acosta-Coley et al, 2019;Frias et al, 2010;Mazariegos-Ortíz et al, 2020;Pannetier et al, 2019;Pérez-Alvelo et al, 2021). Organic compounds (brominated flame retardant, PCBs, chlorinated pesticides, and PAHs) were found on both sampling sites, but with higher concentrations in MG than in PB, along with the detection of phthalates.…”

“…Many species are known to grow under elevated UV-radiation, desiccation and salinity, and break down long-chained hydrocarbons such as chitin, cellulose, lignin and crude oil, as well as on human-made materials, such as rubbers, silicone and different types of plastic [ 9 , 10 , 38 , 39 ]. Human-made materials are increasingly represented in the environment with a growing population, and frequently end up in the oceans [ 40 , 41 ]. Beach sand and sea bordering urban places usually meet many of the above-described conditions as explained in detail in the white paper “Beach sand and the potential for infectious disease transmission: observations and recommendations” [ 12 ].…”

Beach safety regulation is based on faecal indicators in water, leaving out sand and fungi, whose presence in both matrices has often been reported. To study the abundance, diversity and possible fluctuations of mycobiota, fungi from sand and seawater were isolated from the Portorož beach (Slovenia) during a 1-year period. Sand analyses yielded 64 species of 43 genera, whereas seawater samples yielded 29 species of 18 genera. Environmental and taxonomical data of fungal communities were analysed using machine learning approaches. Changes in the air and water temperature, sunshine hours, humidity and precipitation, air pressure and wind speed appeared to affect mycobiota. The core genera Aphanoascus, Aspergillus, Fusarium, Bisifusarium, Penicillium, Talaromyces, and Rhizopus were found to compose a stable community within sand, although their presence and abundance fluctuated along with weather changes. Aspergillus spp. were the most abundant and thus tested against nine antimycotics using Sensititre Yeast One kit. Aspergillus niger and A. welwitschiae isolates were found to be resistant to amphotericin B. Additionally, four possible human pollution indicators were isolated during the bathing season, including Meyerozyma, which can be used in beach microbial regulation. Our findings provide the foundations for additional research on sand and seawater mycobiota and show the potential effect of global warming and extreme weather events on fungi in sand and sea.

“…First, 200 g of dry sample from each sample was added to saturated sodium chloride solution (1.21 g/ml) fully stirred with a glass rod and allowed to stand for at least 24 hours. 1.2g/ml NaCl solution was mostly recommended (Andrady, 2011;Pinheiro et al, 2019;Bissen & Chawchai, 2020;Perez-Alvelo et al, 2021;Rangel-Buitrago et al, 2021), which was higher than the density of common plastic polymers such as polypropylene (PP: 0.9-0.91 g/ ml), polyethylene (PE: 0.917-0.965 g/ ml) and polystyrene (PS: 1.04-1.1 g/ ml). Then, the suspension overlying the sediment was removed by the siphon method.…”

Microplastic pollution on bathing beaches threatens the health of human beings and coastal organisms. There is a lack of assessment on the level of microplastic pollution and the health risk associated with plastics. As one of the earliest open bathing beaches in China, Liandao is well known as the two high-quality beaches. However, little is known about the extent of microplastic pollution on these bathing beaches. Based on the analysis of microplastic pollution abundance, distribution, shape, size, color, and composition at the Liandao bathing beaches, this study puts forward a novel approach to comprehensively evaluate the microplastic pollution level and risk level by using the Nemerow pollution index (NPI) and polymer hazard index (PHI). The results show that the average abundance of microplastics on the Liandao bathing beaches is 135.42 ± 49.58 items/kg; the main shapes are fibers, fragments, and granules. Most of the microplastics are transparent, brown, and black, accounting for 71.54%, and they have an average particle size of 0.63 ± 0.43 mm. The main components are PE, PP, PS, PET, and nylon, of which nylon appears in the highest proportion (54.77%). The microplastic NPI and PHI values are 0.38 and 74.81, respectively, indicating that the pollution level and health risk index of microplastics on the Liandao bathing beaches are both low. With the increase in population and per capita consumption, plastic waste generated on land will continue to increase. Finally, this study puts forward some suggestions regarding microplastic monitoring, plastic waste management, and environmental attitudes and behavior.
