Any marine organisms found within the debris were identified and measured.

Among the plastic debris, 250 organisms of 23 species were found trapped, showing a positive correlation (r = 0.71, p < 0.001) between marine benthic plastic debris and bycatch. Three species, <em>Metapenaeopsis barbata</em>, <em>Acropoma japonicum,</em> and <em>Nuchequula nuchalis</em>, were selected for the selectivity analysis. The contact probability model fits better for experimental tows, while the logistic model fits better for control tows for all three species. The estimated contact probabilities were 0.62, 0.48, and 0.59 for the three species. The selectivity curve indicated higher retention probabilities for smaller fish in nets containing plastic bags, suggesting that marine debris adversely affects the selectivity of trawl nets by trapping small organisms.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"217 ","pages":"Article 118127"},"PeriodicalIF":5.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to evaluate and identify anthropogenic impacts on marine turtle populations in the Lençóis Maranhenses National Park. Between 2015 and 2019, systematic monitoring recorded 173 marine turtle strandings, including 164 dead and nine live individuals of <em>E. imbricata,</em> predominantly of <em>C. mydas</em> (46.2 %, <em>n</em> = 80), <em>L. olivacea</em> (38.2 %, <em>n</em> = 66), <em>E. imbricata</em> (5.2 %, <em>n</em> = 9), <em>C. caretta</em> (0.6 %, <em>n</em> = 1), and 9.8 % (<em>n</em> = 17) unidentified. Among the 44 individuals with determined causes of death, 79.5 % (<em>n</em> = 35) were linked to anthropogenic actions, 9 % (<em>n</em> = 4) to natural causes, and 11.3 % (<em>n</em> = 5) to mixed anthropogenic/natural factors. The remaining 129 cases were classified as indeterminate. A significant increase in strandings was observed during the 3D seismic survey period (mean = 34.4 strandings/bimester) compared to periods without seismic activity (mean = 4.8 strandings/bimester). These results underscore that cumulative threats, particularly human-driven pressures, severely impact marine turtle populations. An enhanced understanding of these dynamics is critical for developing targeted conservation strategies at Lençóis Maranhenses National Park.

While bio-based dispersants are gaining attention as alternatives to chemical dispersants, limited research exists on their adaptability to varying salinity conditions and their associated molecular mechanism and ecological impact. This study evaluated the DE of bio-based dispersants formulated with two biosurfactants (BS); Surfactin (SUC) and Rhamnolipid (RAM), either individually or in combination with Tween 80 (TWE), referred to as BS/TWE, across salinity levels of 10, 20, and 34 psu.

The SUC-based dispersant achieved high DE (88 %) with smallest oil droplets size around 5.08 μm at 10 psu but exhibited reduced performance at 34 psu. In contrast, the BS/TWE dispersant showed 90 % DE with droplets size of 10.45 μm at 34 psu, as a result of synergistic surfactant interactions. Molecular dynamics simulation revealed that salinity affects surfactant-water interactions, with SUC-based dispersant losing efficiency at high salinity due to lack of ion bridging, while BS/TWE dispersant remaining effective through reduced electrostatic interactions. Toxicity assessments exhibited minimal inhibitory effects of bio-based dispersants on algal growth, <em>Dunaliella tertiolecta,</em> highlighting their potential for environmental applications.
