Abstract Sandy beaches are ecologically important coastal ecosystems that increasingly threatened by plastic pollution. This pollution disrupts their ecological balance and reduces ability to provide ecosystem services. study case at Joaquina Beach, Santa Catarina Island, southern Brazil, aimed assess the spatiotemporal contamination macro mesoplastics concerning meteorological anthropogenic variations, identify potential sources for region. Over 18 months (December 2018 March 2020), monthly collections of macroplastics were performed 12 fixed sampling points. The amount found was 216 items, with an average 2.18 items m-2 (range: 0-17.33 m-2), a higher density than macroplastics, which, 1069 found, 0.32 0-2.2 m-2). Fragments predominant type in both size categories. region assessed as “very clean” only once during monitoring, Clean-Coast Index classifying it “clean” 59% months. 2019 had highest macroplastic amount, followed April February 2020. Meanwhile, mesoplastic quantity 2019, December 2018, January 2019. For categories, beach users identified main possible source litter, smaller contribution from fishing activities. However, conditions, like wind direction, can also contribute accumulation area. concentration meso occurrences prevailing pattern winds. contributes knowledge addressing mesoplastics, providing useful information bridge scientific management gaps regarding distribution different sizes.

The coastal zone consists of diverse littoral habitats, which we categorize into two primary types: linear and areal. Investigating habitats is crucial for resolving the ‘coastal squeeze’ phenomenon in marine protected areas seaside resorts.
