The estuarine plastics menace: Insights into prevalence, characterization and polymeric risk assessment of microplastics in the Mahi River Estuary, Gujarat, India Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-17 Krunal Pokar, Vasantkumar Rabari, Rishiraj Duggal, Ashish Patel, Heris Patel, Krupal Patel, Virendra Kumar Yadav, Sami Al Obaid, Mohammad Javed Ansari, Jigneshkumar Trivedi
Microplastic contamination (MP) has created havoc in all eco-systems especially the estuarine environment. The current investigation focused on assessing MP contamination along the Mahi River Estuary in Gujarat. Thirty sampling sites were selected along the estuary, spanning from Khambhat to Kamboi. Sediment samples were collected, processed, and analyzed for MPs. A total of 1371 MP particles were

Sunken oil mats: A biomarker-based investigation Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-17 Rafael André Lourenço, Rafael Patrick R. Marcelino, Gabrielle Vieira Lube, Guillaume Lassalle, Rebecca Del'Papa Moreira Scafutto, Carlos Roberto de Souza Filho
Sunken oil mats (SOMs) pose a significant threat to marine ecosystems, yet their long-term fate and weathering processes remain poorly understood. This study investigates the degradation of biomarkers in a SOM sample collected from the Brazilian coast following the long-lasting 2019 oil spill. The SOM clearly distinguished from spilt oil and were attributed to tanker-washing residues. Analysis of its

Gonadal rematuration and sex-specific reproductive impairment in Manila clams under ocean acidification Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-17 Xiaoyan Jiang, Fortunatus Masanja, Weinan Li, Jiancheng Li, Liusuan Xu, Yang Xu, Xin Luo, Yong Liu, Liqiang Zhao
Ocean acidification (OA) can affect marine bivalves at various levels of biological organization. Yet, little effort has been devoted to understanding how OA affects the reproductive events of marine bivalves during multiple cycles of maturation. Here, we tested sex-specific reproductive responses of Manila clams (Ruditapes philippinarum) to OA during gonadal rematuration. Under acidified conditions

Organochlorine pesticides and polychlorinated biphenyls in sediments of the Lanzhou reach of Yellow River (China): Spatial distribution, sources and risk assessment Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-16 Longmiao Yuan, Yingqin Wu, Leiping Shi, Jiayu Song, Yufeng Jiang
Knowledge about sediment levels and sources of persistent organic pollutants (POPs) in Lanzhou section Yellow River remains limited. Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) levels in 12 sediment samples from this region were measured by GC/MS. OCPs concentrations ranged from 85.6 to 202 ng/g, while PCBs levels varied between 3.08 and 32.3 ng/g. Our findings demonstrated

Oil spill impact on Brazilian coral reefs based on seawater polycyclic aromatic hydrocarbon contamination, biliary fluorescence and enzymatic biomarkers in damselfish Stegastes fuscus (Teleostei, Pomacentridae) Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-16 Maria Karolaine de Melo Alves, Célio Freire Mariz Jr, Thalita Joana Bezerra de Melo, Romulo Nepomuceno Alves, Lino A. Valcarcel, Eliete Zanardi-Lamardo, João Lucas Leão Feitosa, Paulo S.M. Carvalho
The crude oil contamination along the Brazilian Northeast coast significantly impacted reef ecosystems. This study assessed polycyclic aromatic hydrocarbons (PAHs) in seawater, fluorescence of bile PAHs, and biochemical biomarkers in damselfish Stegastes fuscus across four coral reef areas pre- and post-oil contamination. Serrambi (SE) and Japaratinga (JP1) were identified as suitable reference areas

Trace elements in two endemic fish species (Barbus strumicae, Karaman 1955 and Squalius оrpheus, Kottelat & Economidis, 2006) of Nestos River (NE Greece): Levels, organ bioaccumulation and potential health risk Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-15 Nikolaos Kamidis, Argyrios Sapounidis, Thomas Spanos, Christina Chatzichristou, Vilson Topi, Stelios Triantafillidis, Dimitrios Karampetsis, Paraskevi Papadopoulou, Sophia Mitkidou, Nikolaos Kokkinos, Antoaneta Ene, Nikolaos Stamatis
This paper aims to determine the content and bioaccumulation patterns of eight trace elements (Li, Cr, Co, As, Se, Cd, Pb and Hg) and one radioisotope (U) in kidney, liver and muscle tissues of two fish species (Squalius orpheus and Barbus strumicae) from Nestos River (northern Greece), and the potential human health risk due to the fish muscle consumption. Kidney and liver accumulate higher element

Microplastics pollution in sediments of the Thames and Medway estuaries, UK: Organic matter associations and predominance of polyethylene Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-14 Megan M. Trusler, Vicky L. Moss-Hayes, Sarah Cook, Barry H. Lomax, Christopher H. Vane
Microplastics at 10 sites along a 77 km transect of the river Thames estuary (UK) and 5 sites along 29 km of the Medway estuary were separated from sediment and analysed by ATR-FTIR spectroscopy. Microplastics were observed at all sites. Highest Thames concentrations were in urban London between Chelsea and West Thurrock (average 170.80 particles kg−1 ± 46.64, 3.36 mg kg−1 ± 1.79 by mass), mid-outer

Behavioural response of Australian fur seals (Arctocephalus pusillus doriferus) to vessel noise during peak and off-peak human visitation Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-14 Jessalyn J. Taylor, Rebecca R. McIntosh, Rachael B. Gray, Isabelle Charrier
Vessel traffic is the greatest contributor to marine anthropogenic noise pollution, and particularly affects species utilising coastal areas. Seal Rocks (Victoria), the largest Australian fur seal breeding colony, has a relatively small vessel exclusion zone during the pupping and breeding season, when vessel traffic is at its peak. It is necessary to understand the impacts of visitation at sensitive

Comparison of conventional and machine learning regression models for accurate prediction of selected optical active components – A case study: The Gulf of Izmit Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-14 Filiz Sunar, A. Dervisoglu, N. Yagmur, H. Atabay, A. Donertas
This study hypothesizes that advanced machine learning (ML) models can more accurately predict certain critical water quality parameters in marine environments compared to conventional regression techniques. We specifically evaluated the spatio-temporal distribution of Chlorophyll-a (Chl-a) and Secchi Disk Depth (SDD) in the Gulf of Izmit using in-situ measurements and Sentinel-2 satellite imagery

Occurrence of plastic additives in coral-reef invertebrates on natural and plastic substrates Mar. Pollut. Bull. (IF 5.3) Pub Date : 2024-09-14 Gal Vered, Olivia Nordland, Igal Gozlan, Noa Shenkar
Numerous studies have investigated the occurrence of plastic additives in marine biota. Yet, their main vector of transfer into organisms tissues remains unknown. We explored seven common additives in benthic coral reef invertebrates residing on natural/plastic substrates in a protected marine reserve versus an unprotected reef to ascertain whether additives transfer by substrate leaching. Samples
