Microplastic and mesoplastic pollution in surface waters and beaches of the Canary Islands: A review Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-03-13 Andrea García-Regalado, Alicia Herrera, Rodrigo Almeda
The Canary Archipelago is a group of volcanic islands located in the North Atlantic Ocean with high marine biodiversity. This archipelago intercepts the Canary Current, the easternmost branch of the Azores Current in the North Atlantic Subtropical Gyre, which brings large amounts of litter from remote sources via oceanic transportation. It is, therefore, particularly vulnerable to marine plastic pollution

Survey of parasites in sea turtles rescued off the coast of Santa Catarina and Paraná, Brazil (2020-2022) and their relationship with marine pollution Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-23 Ricardo Andrade Barata, Emerson Cotta Bodevan, Fábio de Souza Kirchpfennig
The identification of parasite fauna can contribute to the assessment of the health status of sea turtles, and thus make it possible to develop effective management and treatment strategies aimed at conserving these animals. The present study aimed to investigate the parasite fauna in sea turtles rescued in six sections of the coast of Santa Catarina and Paraná (Brazil) from January 2020 to December

A study into the diversity of coral-associated bacteria using culture-dependent and culture-independent approaches in coral Dipsastraea favus from the Gulf of Kutch Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-23 Zarna Z. Patel, Himanshu Joshi, Apurvasinh Puvar, Ramesh Pandit, Chaitanya Joshi, Madhvi Joshi, Devayani R. Tipre
Corals harbour ~25 % of the marine diversity referring to biodiversity hotspots in marine ecosystems. Global efforts to find ways to restore the coral reef ecosystem from various threats can be complemented by studying coral-associated bacteria. Coral-associated bacteria are vital components of overall coral wellbeing. We explored the bacterial diversity associated with coral () collected from the

Relevance of flounder caging and proteomics to explore the impact of a major industrial accident caused by fire on the Seine estuarine water quality Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-23 Jennifer Laurent, Mamadou Diop, Rachid Amara, Cédric Fisson, Jean Armengaud, Pierre Labadie, Hélène Budzinski, Jérôme Couteau, Géraldine Maillet, Stéphane Le Floch, Jean Laroche, Vianney Pichereau
On September 26th 2019, a major fire occurred in the Lubrizol factory located near the Seine estuary, in Rouen-France. Juvenile flounders were captured in the Canche estuary (a reference system) and caged one month in the Canche and in the Seine downstream the accident site. No significant increases of PAHs, PCBs and PFAS was detected in Seine Canche sediments after the accident, but a significant

Marine turtles as bio-indicators of plastic pollution in the eastern Mediterranean Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-23 Emily M. Duncan, Hasan Deniz Akbora, Patrizia Baldi, Damla Beton, Annette C. Broderick, Burak Ali Cicek, Charlotte Crowe-Harland, Sophie Davey, Tess DeSerisy, Wayne J. Fuller, Julia C. Haywood, Yu Jou Hsieh, Ecem Kaya, Lucy C.M. Omeyer, Meryem Ozkan, Josie L. Palmer, Emma Roast, David Santillo, M. Jesse Schneider, Robin T.E. Snape, Katrina C. Sutherland, Brendan J. Godley
The loggerhead turtle () has been suggested as a bio-indicator species for plastic pollution. However, detailed investigations in the eastern Mediterranean are limited. Here, we present data from loggerhead turtles (2012-2022; = 131) of which 42.7 % ( = 57) had ingested macroplastic (pieces ≥ 5 mm). Frequency of occurrence (%) was not found to have changed over time, with body size (CCL cm), between

Anthropogenic litter in a Mediterranean coastal wetland: A heterogeneous spatial pattern of historical deposition Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-23 Corrado Battisti, Giulia Cesarini, Luca Gallitelli, Filippo Moretti, Massimiliano Scalici
Coastal wetlands represent areas that can testify historical accumulation of litter. We analyzed the anthropogenic litter deposited on the channel bottom of a coastal wetland area that experienced water stress due to extreme summer dryness after about 20 years. We hypothesize that the litter accumulated in the different areas over the years reflects the different social user categories (i.e., fishermen

Bioaccumulation of pollutants in the green-lipped mussel Perna viridis: Assessing pollution abatement in Victoria Harbour and its adjacent aquaculture area, Hong Kong, and the minimal human health risks from mussel consumption Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-22 Ryan Kar-Long Leung, Apple Pui Yi Chui, Xiaoshou Liu, Hang-Wai Lee, Matthew Ming-Lok Leung, Youji Wang, Menghong Hu, Kevin Wing Hin Kwok, Rudolf Shiu Sun Wu, Ling Jin, Hang-Kin Kong, James Kar-Hei Fang
The green-lipped mussel was utilised for pollution biomonitoring in Victoria Harbour and its adjacent aquaculture area in Hong Kong. was collected from a reference site and redeployed at five study sites for five weeks during the dry and wet seasons of 2019. Our study found various polycyclic aromatic hydrocarbons (PAHs) and heavy metals in the mussel tissue, while polychlorinated biphenyls (PCBs)

Salinity and pH related microbial nitrogen removal in the largest coastal lagoon of Chinese mainland (Pinqing Lagoon) Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-22 Dongchen Han, Yiguo Hong, Jiapeng Wu, Hanbiao Xian, Xuhui Dong, Honglei Liu, Fei Ye, Yu Wang
Coastal lagoon is critical habitat for human and provides a wide range of ecosystem services. These vital habitats are now threatened by waste discharge and eutrophication. Previous studies suggest that the pollution mitigation of coastal lagoon relies on the water exchange with open sea, and the role of microbial processes inside the lagoon is overlooked. This study takes the Pinqing Lagoon which

Unveiling the evolution of phytoplankton communities: Decades-long insights into the southern Yellow Sea, China (1959–2023) Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-22 Shujin Guo, Xiaoxia Sun, Jian Zhang, Qingzhen Yao, Chuanjie Wei, Feng Wang
We obtained historical and observational data on phytoplankton communities from 1959 to 2023 to explore the responses of the phytoplankton community structure to long-term environmental changes in the southern Yellow Sea (SYS), China. The results revealed a decrease in the proportions of diatom cell abundance within the phytoplankton community by 8 %, accompanied by a corresponding increase in that

Predicting the effect of fouling organisms and climate change on integrated shellfish aquaculture Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-02-22 A. Giacoletti, M. Bosch-Belmar, M.C. Mangano, M.F. Tantillo, G. Sarà, G. Milisenda
Aquaculture industry represents a continuously growing sector playing a fundamental role in pursuing United Nation's goals. Increasing sea-surface temperatures, the growth of encrusting species and current cage cleaning practices proved to affect the productivity of commercial species. Here, through a Dynamic Energy Budget application under two different IPCC scenarios, we investigate the long-term
