Antonija Bulić, Stjepan Orhanović, Ivana Pezelj, Ivana UjevićCyclic imines (CIs) are lipophilic marine toxins produced by dinoflagellates, that are known for their neurotoxic effects and have raised concern among food regulatory agencies due to insufficient data on their presence. This study is the first to systematically investigate the possible presence of 29 CIs in shellfish from the southern Adriatic Sea in Croatia. Liquid chromatography-tandem mass spectrometry

Changes in the abundance, concentration, and composition of the microplastics and fibers in gray seals (Halichoerus Grypus Atlantica) scat on Nantucket Island in July and November 2019 and January 2020 Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-04-01
Shannon Hogan, Stephanie Wood, Juanita Urban-RichMarine mammals are important bioindicators for pollution such as microplastics and ecosystem health. This study is the first to report the presence of fibers and microplastics (hard fragments, foams, films, tire pieces, and knots) in gray seal (Halichoerus grypus atlantica) scat from Nantucket Island in the Northwest Atlantic. Microplastics and fibers (MPF) were found in 100 % of the scat (n = 19)

Developing a harmonized decision framework for shoreline marine debris monitoring across APEC economies Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-04-01
Jongsu Lee, Jongmyoung Lee, Sunwook HongThis study presents a harmonized decision framework to guide APEC economies in designing shoreline marine debris monitoring programs. By reviewing 31 monitoring programs, we identified five core elements of goals/objectives, debris targets, spatial scale, data collection and management practices and developed eleven decision criteria to guide program design, including objectives, debris size, categories

Examining the effect of intensive seismic surveys on abundance and behaviour of groundfish species along a continental slope of Newfoundland and Labrador, Canada Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-31
Khanh Q. Nguyen, Jacqueline M. Hanlon, Bruce S. Martin, Pablo Borys, Dustin Schornagel, Corey J. MorrisThis study investigated changes in the abundance and behaviour of groundfish species at a relatively deep-water site along the eastern continental slope of Canada, when exposed to a commercial seismic survey that lasted 100 consecutive days. Baited cameras were deployed at control and impact sites, before and after seismic exposure, consisting of 323, 5-h long, videos. Changes in abundance were not

Analysis and prediction of the impact of Fukushima nuclear polluted water on the Chinese sea area Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-31
Wu Men, Guohua Zheng, Fenfen Wang, Gexinyan Zhou, Quandi LiuDischarge of Fukushima nuclear polluted water (NPW) into the ocean has aroused a new round of public concern. Based on the previous research findings and the data released by Japan, this work discusses transport of NPW in the North Pacific Ocean, the time required for NPW to reach the Chinese Sea area, variations in activity concentrations, and radiation effects on the marine organisms to predict the

Factors influencing the outbreak of Phaeocystis (Prymnesiophyceae) bloom in the coastal waters off Digha Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-31
L. Jagadeesan, Ignatious Joseph, G. Naveen Sagar, Krishna Murukan, S. Balakrishnan, Arijit Banik, G. Sahoo, P. Nihal, C. Akshara, K.K. BalachandranPhaeocystis blooms are considered harmful algal blooms due to its negative impacts on the ecosystem. This study investigates the responsible factors for outbreak of Phaeocystis bloom in the coastal waters off Digha (Northwestern Bay of Bengal). Phaeocystis bloom was first observed along Talsari Beach over a ∼ 150 sq.km during early December 2022. The bloom reappeared in the same region during December

Persistent elevated levels of dissolved lead in the Indian Ocean post-leaded gasoline ban: The impact of anthropogenic activities, sediment desorption, and dust storms Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-31
Chhaya Yadav, Sunil Kumar Singh, Venkatesh ChinniThis study examines the distribution of dissolved lead (dPb) in the Indian Ocean, based on seawater samples collected during winter monsoon GI10 (2020) and spring inter-monsoon GI09 (2021) cruises. A total of 510 samples were analyzed for dPb concentrations using HR-ICP-MS coupled with seaFAST system. The study emphasizes the spatial distribution of dPb in the Indian Ocean, identifying major sources

Ocean noise contributors in southern resident killer whale habitat Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-31
Alexander O. MacGillivray, Forest M.C. Stothart, Connor H. Grooms, Zizheng Li, Mikhail M. ZykovThe contributions of different marine sectors to underwater noise pollution within endangered Southern Resident killer whale (SRKW) habitat were investigated using a soundscape model for continental shelf waters off British Columbia and Washington State. Inputs to the model included Automatic Identification System (AIS) vessel traffic data, aerial survey estimates of non-AIS traffic, and an extensive

Response of diatoms to environmental changes in the Porphyra cultivation system in Haizhou Bay using GBT model and GAM Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-30
Shuo Chen, Haibin Han, Jinchen Yu, Tao Sun, Jin ZhouHaizhou Bay hosts extensive Porphyra cultivation zones, constituting a significant component of the regional aquaculture industry. To investigate the spatiotemporal variations of phytoplankton, particularly diatoms, and their response to Porphyra cultivation activities, monthly surveys of the phytoplankton community structure and environmental variables were conducted in Haizhou Bay throughout 2023

Occurrence, spatiotemporal distribution and environmental behavior of dissolved, particulate, and sedimentary black carbon in a subtropical coastal environment: Differences between semi-enclosed and open estuaries Mar. Pollut. Bull. (IF 5.3) Pub Date : 2025-03-29
Jingyu Wang, Ruijie Zhang, Jingzhen Wang, Liwei Mo, Zhehong Ji, Pan Wei, Chaoshuai Wei, Kefu YuBlack carbon (BC) plays a critical role in climate change and the carbon cycle as a long-term carbon sink. Estuaries, as key interfaces between land and ocean, are important not only for BC transport but also for its transformation and deposition. This study used the benzene polycarboxylic acid (BPCA) method to quantify BC concentrations in the surface waters and sediments of semi-enclosed and open
