“…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.…”

“…Research on microplastics on recreational beaches is extremely limited (Piehl et al, 2019;Yabanli et al, 2019;Bissen & Chawchai, 2020;Wu et al, 2021). Studies have focused mainly on the basic characteristics of beach microplastics, such as abundance, distribution, shape, size, and composition (Lots et al, 2017;Piehl et al, 2019;Pinheiro et al, 2019;Yabanli et al, 2019;Bissen & Chawchai, 2020;Pérez-Alvelo et al, 2021;Rey et al, 2021); influencing factors of microplastic pollution (Herrera et al, 2018;Isabel et al, 2019;Pinheiro et al, 2019;Tziourrou et al, 2019;Vidyasakar et al, 2018); and sources of microplastic pollution (Hengstmann et al, 2018;Herrera et al, 2018;Vidyasakar et al, 2018;Yabanli et al, 2019;Pérez-Alvelo et al, 2021). The density flotation method is often used for the extraction of microplastics (Hengstmann et al, 2018;Piñón-Colin et al, 2018), and ATR-FLIR spectrometry, Raman spectrometry, and the HIS-NIP method are usually used for the identification of microplastics (Esiukova et al, 2021;Lots et al, 2017;Piehl et al, 2019;Tsukada et al, 2021;Tziourrou et al, 2019).…”

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.

“…For evaluation of MPs, a volume of 5 cm 3 of sediment with variable mass was transferred into 15-ml tubes and dried at 40 °C, weighed with an analytical balance and transferred into beakers containing saline solution (1.2 g cm -3 NaCl-Coralife), and MPs were isolated by flotation and then filtered (Hidalgo-Ruz et al, 2012;Pinheiro et al, 2019). Each filter was transferred to a Petri dish, which was closed and stored at 40 °C before analysis under a stereomicroscope (Olympus SZX9) with an attached camera protected by a chapel.…”

The combined use of paleolimnological and long-term limnological information to identify natural and anthropogenic environmental changes

Aim Urbanization leads to rapid changes in ecosystem structure and function. Wetlands on university campuses under urbanization pressure could be used as case studies of multidisciplinary aquatic research and good environmental practices promoting sustainability. Methods A paleolimnological study was undertaken in a semi-artificial lake on a university campus in southern Brazil to trace historical impacts and ecological changes back to the mid-1970s through complementary approaches: historical data, nutrients, δ13C and δ15N stable isotopes, diatoms, microplastics and associated microbial community analysis. Results The eutrophication process started to intensify after the lake was used for nocturnal roosting by waterbirds, and especially after the establishment of constructions along the margins with septic tank sanitary sewage, which eventually spilled and leached into the lake. Over decades, we identified a limnological hypertrophication process leading to recurrent cyanobacterial blooms and massive macrophyte proliferation coupled with changes in isotopic ratios and algal occupation with several transitions between shallow lake alternative states. Such a limnological process has resembled the paleolimnological eutrophication trends and isotopic changes in sedimentary organic matter. The microplastic deposition was detected as a proxy for the intensification of urbanization, especially during the construction of the University facilities. Conclusions The combined use of paleolimnological and historical limnological data represents a powerful approach for inferring both natural and cultural impacts on the lake, and identifying management strategies based on such scientific information.

“…McWilliams, Liboiron e Wiersma (2018) recomendam que, em praias rochosas, outros protocolos de amostragem sejam adotados, visto que os resíduos podem estar localizados em maiores profundidades na areia. Para Pinheiro et al (2019), na Praia de Boa Viagem (Recife, Brasil), a quantidade de microplásticos foi maior nas áreas protegidas por beachrocks do que em áreas expostas às ondas, podendo estar relacionado à menor hidrodinâmica da área. Esses beachrocks encontram-se paralelos à costa, diferindo dos promontórios rochosos presentes em Torres.…”

“…Em regiões costeiras, além desses fatores, a geomorfologia costeira e as ressacas podem influenciar significativamente os padrões de acumulação do plástico nas praias (Falcão & Souza, 2014;Lozoya et al, 2016), assim como a proximidade de fontes emissoras, como as regiões portuárias, rotas comerciais e áreas urbanas (Barnes et al, 2009). O sedimento de praias é um dos ambientes mais estudados quanto à poluição por MPs (Pinheiro et al, 2019). Regiões costeiras densamente urbanizadas são reconhecidas como uma fonte terrestre de contaminação e têm sido estudadas no mundo todo (Coley & Verbel, 2015;Nel et al, 2016;Lozoya et al, 2016;Antunes;Frias & Sobral, 2018), embora áreas sem ação antrópica também apresentem significativo acúmulo (Baztan et al, 2014;Alomar;Estarellas & Deudero, 2016), demonstrando a sua ampla dispersão pelos ambientes costeiros e marinhos.…”

Este estudo analisou a presença de microplásticos no sedimento arenoso em três praias no litoral norte do Rio Grande do Sul – Sul do Brasil, com diferentes níveis de antropização. As praias de Torres e Capão da Canoa são mais urbanizadas que a Praia das Cabras (Cidreira). A amostragem foi realizada ao longo das quatro estações do ano. Em cada localidade, foram amostradas seis parcelas quadradas (0,5 x 0,5 m), incluindo três pontos na marca da preamar e três pontos na base das dunas. A presença de microplásticos foi registrada em todas as amostras. No total, foram coletados 1.727 microplásticos (886 unidades de fragmentos e 841 unidades de pellets). A Praia das Cabras apresentou maior concentração de microplásticos (1.083 unidades) do que as praias urbanizadas: Capão da Canoa (482 unidades) e Torres (162 unidades). Além disso, foi encontrada grande quantidade de pellets na Praia das Cabras, enquanto as outras duas praias apresentaram maior acúmulo de fragmentos. O maior acúmulo de microplásticos foi encontrado durante a primavera (687 unidades), seguida pelo inverno (462 unidades), verão (410 unidades) e outono (168 unidades). A presença de microplásticos em praias arenosas parece não estar relacionada somente à urbanização, mas também à interação continente-oceano.
