“…Surprisingly, we did not find a direct relationship of marine litter density with population density (Leite et al, 2014). Although these two parameters showed the highest values in the Saronikos Gulf, in Constanta Bay which is the second most populated area, marine litter density was found lower than in the Gulf of Patras or the Echinades Gulf.…”

In the present work, abundance, spatial distribution and qualitative composition, of benthic marine litter, were investigated in five study areas from the Eastern Mediterranean and Black Seas (Saronikos, Patras and Echinades Gulfs; Limassol Gulf; Constanta Bay). Surveys were performed using the monitoring protocol proposed by the Technical Group for Marine Litter. Densities ranged from 24items/km(2) to 1211items/km(2), with the Saronikos Gulf being the most affected area. Plastics were predominant in all study areas ranging from 45.2% to 95%. Metals and Glass/Ceramics reached maximum values of 21.9% and of 22.4%. The size distribution of litter items showed that ⩾50% fall into medium size categories (10×10cm, 20×20cm) along with an elevated percentage of small-sized (<5×5cm) plastic litter items. The comparative analysis of the data highlighted the dependence of the marine litter problem on many local factors (human sources and oceanographic conditions) and the urgent need for specific actions.

“…However, these activities are ineffective, especially regarding the removal of smaller plastic fragments, which usually escape the most common cleaning methods (raking) (Fernandino et al 2015). In some cases, as reported by Leite et al (2014), the frequency of cleaning efforts on the beaches of Salvador can significantly reduce the amount of litter on beaches, such is the case of Porto da Barra beach (P03), which is cleaned twice a day. Despite this effort, the beach in question was classified in the present study as extremely dirty with CCI = 28 at the moment of sampling.…”

“…Analogously to the transportation of sediment particles, these currents can also transport litter, which can be deposited or redeposited, depending on factors such as seasonality, intensity of currents and litter density, in areas far from where they were originated. Marine litter can be found in higher concentrations in the surrounding areas of great urban centers (Moore & Allen 2000;Leite et al 2014). The proximity to urban centers is a determinant factor to its occurrence (Backhurst & Cole 2000).…”

Urban areas are hotspots for marine litter. Plastic materials are the most common type of beach litter and can fragment into even smaller pieces. A total of 24 sampling stations were distributed along the coast of Salvador, Brazil, from which every litter item > 2 cm was sampled. A total of 17,089 items were sampled from the beaches of Salvador in two different survey seasons (10,416 during the winter and 6,673 during the summer). Plastic represented 87.45% of all materials sampled during the winter and 85.24%, during the summer. In both seasons, the majority of the sampled beaches were classified as extremely dirty according to the Clean-Coast Index. Plastic fragments were found in every sampling station in both field surveys, representing 45.7% of the overall plastic items sampled. Tourism/recreation activities appeared to be important sources of litter to the area.

“…all play a role from global to very small scales (e.g. Abu-Hilal and Al-Najjar, 2004;Browne et al, 2010;Cunningham and Wilson, Duhec et al, 2015;Goldstein et al, 2013;Isobe et al, 2014;Lebreton et al, 2012;Leite et al, 2014;Poeta et al, 2014;Ryan, 2013;Titmus and Hyrenbach, 2011;Turra et al, 2014). These influences may affect debris deposition even at remote beaches, and therefore also on their management.…”

Highlights• Marine debris was studied on 15 islets of St. Brandon's Rock, Indian Ocean • Plastics made up 79% of 50 000 debris items at 0.74 items m -1 shore length Intact CFLs suggests product-facilitated long-range transport of mercury. We suspect that aggregated marine debris, scavenged by the islands from currents and gyres, could re-concentrate pollutants. SBR islets accumulated debris types in different proportions suggesting that many factors act variably on different debris types. Regular cleaning of selected islets will take care of most of the accumulated debris and may improve the ecology and tourism potential. However, arrangements and logistics require more study.
