“…Coastal beaches are located in the transitional zone between marine and terrestrial domains. They provide many essential services, including the prevention of wave erosion, Toxics 2024, 12, 375 2 of 15 water purification, and habitats for organisms [22][23][24]. However, owing to recreational and tourism development, coastal beaches are vulnerable to the entrapment of microplastic debris [24].…”

“…However, owing to recreational and tourism development, coastal beaches are vulnerable to the entrapment of microplastic debris [24]. Previous studies detected a wide distribution of microplastics in beach sediments, water columns, and organisms [23,25,26]. These particles are mainly derived from terrestrial and marine sources via river transport and tidal deposition [27][28][29].…”

Coastal beaches are vulnerable to microplastic pollution originating primarily from terrestrial and marine sources or the in situ weathering of plastic waste. The present study investigates the effects of rainfall events on the composition and diversity of microplastics on beaches in Xiamen City on a short-term scale. In the results, the quantity of microplastics in beach sediments was 245.83 ± 11.61 items·kg−1 (mean ± standard error). The abundance of microplastics did not differ after each rainfall event but significantly decreased after multiple rainfall events. When the diversity of microplastics in the coastal area was evaluated, the Shannon-Wiener index and Pielou’s index also decreased from 3.12 and 0.64 to 2.99 and 0.62, respectively, after multiple rainfall events. Rainfall had varying effects on microplastics depending on their size and shape, with particles smaller than 500 μm experiencing pronounced reductions. There was a significant negative correlation between the abundance of microplastics and the grain size of sand, but a positive correlation with sediment moisture content. We encourage the consideration of the potential impact of rainfall events during sample collection to ensure the reliability of the data. We also recommend using diversity indexes to help in understanding the influence of physical processes on microplastic distribution and their mechanisms.

“…Currently, various human impacts, especially litter, pose a serious threat to beaches along the coast [13][14][15][16]. Whatever the source, i.e., land based or marine, litter has a significant impact on the aesthetic quality of beaches, wildlife, human health and the overall functioning of coastal ecosystems [17][18][19][20][21]. Unfortunately, the impacts caused by marine litter are not yet fully understood [22] and beach deterioration caused by litter is currently an out-of-control problem [23] threating the national economies of coastal countries based on 3S tourism [24,25].…”

Beaches are ecologically valuable ecosystems and sites that attract many tourists from all over the world, therefore, knowledge of their environmental conditions to establish sound management strategies is of extreme relevance. This study aims to assess and classify 50 beaches through an innovative coastal management approach called “Sector Analysis”, which integrates Litter grading, the coastal scenic quality and beach typology in order to classify sites into one of three sectors: Green (high value sites), Red (low value sites) and Yellow (sites with contradictory values). Litter Grade makes it possible to classify a site according to the quantity of litter using four grades from “A” (low) to “D” (high amount). The Coastal Scenic Evaluation System (CSES) allows to classify sites into five classes, ranging from extremely attractive natural sites (Class I) to unattractive degraded and urbanized sites (Class V). This innovative methodology for sustainable coastal area management can be easily applied to any beach in the world. The results on Litter Grade and CSES considered in this paper were obtained from previous studies and used to obtain the Sector Analysis that showed only 8 sites (16%) are in the Green sector, 18 sites (36%) in the Red sector and 24 sites (48%) in the Yellow sector. The significant percentage of sites in the Red sector (one third of the sites studied) clearly indicates the degradation that the Moroccan Mediterranean coast has undergone due to considerable anthropogenic activities and the lack of adequate coastal management programs. In this study, various management interventions were proposed to conserve and improve the aesthetic quality of beaches and reduce the impact and presence of litter in the coastal areas.
