“…A mean of 0.99 particles.ind -1 was measured in the sea cucumber (Holothuria kefersteini) with higher contamination in specimens from the polluted, east-facing beach of Rosa Blanca (2.54 particles.ind -1 ) with particles recovered from 100% of individuals (n = 11). These findings are similar to holothurians elsewhere although by no means the highest; Renzi et al 38 report particle concentrations of 3.8 -6.0 particles per individual in the Aeolian Archipelago in the Mediterranean. Extracted particles were a mix of fibres (69%) and fragments (31%) that were mostly modified cellulosics (64%).…”

Ecuador’s Galapagos Islands and their unique biodiversity are a global conservation priority. We investigated the presence, partitioning and environmental drivers of plastic contamination across the marine ecosystem, designing a systematic risk scoring analysis to identify the most vulnerable species. Beach contamination varied by site (macroplastic 0 - 0.66 items.m-2, large microplastics 0 - 448.8 particles.m-2, small microplastics 0 – 74.6 particles.kg-1), with high plastic accumulation on east-facing beaches indicating input from the Humboldt Current. Local littering and waste management leakages accounted for 2% of macroplastic. Microplastics (including synthetic cellulosics) were prevalent in sediments (6.7 - 86.7 particles.kg-1) and surface seawater (0.04 - 0.89 particles.m-3), with elevated concentrations in the harbour suggesting local input. Microplastics were present in all seven marine invertebrate species examined, found in 52% of individuals (n = 123). Risk scoring identified 32 species in need of urgent, targeted monitoring and mitigation including pinnipeds, seabirds, turtles, sharks and corals.

“…Studies also show the presence of microplastics in different fish species of human interest such as large predators [30], small pelagic and planktivorous fish [5,[31][32][33]. Almost all benthic species analysed to date have been shown to ingest microplastics [6,7,34], with a clear difference concerning ingested shapes according to the trophic level [35].…”

“…Recent literature shows different levels of microplastic particles in sediments according to habitat type [5,6] suggesting the need for improved exploration of factors affecting distribution, levels and chemical composition of microplastics in sediments of different transitional water ecosystems (TWEs) as these habitat types were clearly understudied with respect to other marine habitats [7]. Transitional water experiences particularly high human and natural stress [8] leading to high levels of microplastics in the sediments of these aquatic ecosystems [9].…”

Transitional water ecosystems (TWEs), despite their ecological and economic importance, are largely affected by human pressures that could be responsible for significant inputs of litter in the marine environment. Plastic input in coastal ponds, lagoons, river deltas and estuaries, could be driven by a wide range of human activities such as agriculture, waste disposal, municipal and industrial wastewater effluents, aquaculture, fishing and touristic activities and urban impacts. However, it remains unknown what the impact of plastic input in these TWEs could have on natural capital and, therefore, the ability for an ecosystem to provide goods and services to human beings. Given the large interest with regards to the conservation of transitional water ecosystems and the clear exposure risk to plastic and microplastic pollution, this study aims to perform: (i) a bibliometric analyses on existing literature regarding the levels of marine litter in such environments; (ii) a selection among the available literature of homogeneous data; and (iii) statistical analyses to explore data variability. Results suggest that: (i) research on microplastics in these ecosystems did not begin to be published until 2013 for lagoons, 2014 for river mouths and 2019 for coastal ponds. The majority of articles published on studies of microplastics in lagoons did not occur until 2019; (ii) sediments represent the matrix on which sampling and extraction variability allow the statistical analyses on data reported by the literature; (iii) the Analysis of Similarities (ANOSIM) test two-way evidenced that the level of protection of marine and terrestrial areas produced similar values while the habitat type showed low significance in terms of its effect on microplastic levels, shape and size in sediments.

“…It is an ecological and social concern, and a growing issue worldwide (Bauer et al, 2008;Löhr et al, 2017). It represents an important and persistent risk for marine ecosystems due to its non-biodegradability and its potential to be ingested by or to entangle organisms (Bo et al, 2014;Angiolillo et al, 2015;Ferrigno et al, 2017;Renzi et al, 2018Renzi et al, , 2020. The impact of litter on RBs is poorly known.…”

Impact of fishing gears and marine litter is a recognized global socio-ecological issue. Little is known about the extent of the problem in the Mediterranean seabed; even less information is available regarding litter distribution and its effects on deep rhodolith beds. Indeed, Mediterranean rhodolith beds are often remote and not yet sufficiently explored habitats, despite being internationally protected and recognized among the most important benthic communities for biodiversity maintenance. In this study, a quantitative assessment of marine litter and lost fishing gears, observed using a remotely operated vehicle, was carried out in 6 sites off the Campania Coast (Tyrrhenian Sea) characterized by different rhodolith covers. A negative correlation between abundance and richness of both marine litter and abandoned fishing gears with respect to the rhodolith cover was detected, suggesting that indirect human pressure along the coasts and direct effect of fishing activities might negatively damage these habitats. In fact, a lot of abandoned fishing gears and litter were recorded in all the 4 sites of the Gulf of Naples, confirming the high impact of maritime activities in this overcrowded area. Particularly, the Secchitiello site showed a very low mean cover of rhodoliths (<5%) in concurrence with the highest abundance of lost fishing gears and litter. On the contrary, the lowest abundance of fishing gears and litter was recorded in the 2 sites along the Cilento coast, possibly due to the relatively low maritime activities in this poorly inhabited area. In conclusion, this work gives new insights into the anthropic pressure due to marine litter and fishing on deep Mediterranean rhodolith beds, and provides useful data for their management and conservation.
