Occurrence, distribution, and characterization of suspended microplastics in a highly impacted estuarine wetland in Argentina

Binational survey of personal protective equipment (PPE) pollution driven by the COVID-19 pandemic in coastal environments: Abundance, distribution, and analytical characterization

“…On the other hand, some authors have reported the presence of hazardous metals such as Cr and Mo on the surface of MPs fibers found in Claromeco sandy beaches in Argentina ( Truchet et al, 2021 ). Likewise, the same authors have also informed the presence of P as an additive in suspended MPs in a highly impacted estuarine wetland in Argentina ( Forero-López et al, 2021 ).…”

“…In the case of Argentina, the current literature provides a more comprehensive understanding of plastic pollution. For instance, MP pollution has been evidenced in surface water and organisms of the heavily impacted Bahía Blanca Estuary and Claromeco beach, where PP, PE, polyester, PA, cellulose-based, among others have been the dominant polymer types ( Forero López et al, 2021 , Díaz-Jaramillo et al, 2021 , Truchet et al, 2021 , Fernández Severini et al, 2020 , Forero-López et al, 2021 ). In Ushuaia Bay, the southernmost city of Argentina, fibers, and fragments consisting of PA, cellulose-based, and PVC copolymers were found in the mussel Mytilus chilensis ( Pérez et al, 2020 ).…”

“…The higher proportion of fibers was also observed in Arctic polar water (Lusher et al, 2015), the San Francisco Bay (Sutton et al, 2016), and the Xisha Islands (Ding et al, 2019). Studies showed that the main sources of fibers may be related to intensive ship transportation, fisheries, and domestic sewage discharges (Lusher et al, 2015;Sutton et al, 2016;Forero-Lopez et al, 2021).…”

“…Additionally, PET and CP are widely used in the daily life as the packaging materials (Tang et al, 2021). Besides, the dominant color of black in the seawater was also observed in the Haikou Bay, the Bahía Blanca Estuary, and estuary in the Gulf of Mexico (Qi et al, 2020;Forero-Lopez et al, 2021;Sanchez-Hernandez et al, 2021). MPs fibers were mostly black, blue, and transparent in general, and high proportions of black MPs are mainly sourced from tires, abrasives and plastic bags (Lassen et al, 2015).…”

“…MPs fibers were mostly black, blue, and transparent in general, and high proportions of black MPs are mainly sourced from tires, abrasives and plastic bags (Lassen et al, 2015). Moreover, mechanical damage in some fibers (e.g., fractures and color fading) can be associated with the weathering of polymers in seawater, while the digestion process of some animals could aggravate the physical damage in fibers (Forero-Lopez et al, 2021). For example, a recent study reported there were 90% black and blue fibers in the abdominal muscle and digestive tract of the shrimp Pleoticus muelleri (Fernandez Severini et al, 2020).…”
