In this study, surface seawater and sediment samples were collected from Bohai Sea, China, to investigate the temporal and spatial distributions of perfluoroalkyl substances (PFASs) in that area. The total concentrations of PFASs in seawater and sediment samples ranged from below method limit of quantification (

This study examines pollution, ecotoxicological, and health risks of B, F, and S in seawater and sediments along the southern Mediterranean Sea. Strong positive loading on B in sediment, PLI, and NPI suggested that the high B content raises the total amount of contamination and cumulative risks to benthic organisms. Logk for S and F were <3 indicating that they were easily transported to the water column.

Subterranean estuaries (STEs) are critical ecosystems at the interface of meteoric groundwater and subsurface seawater that are threatened by sea level rise. To characterize the influence of tides and waves on the STE microbial community, we collected porewater samples from a high-energy beach STE at Stinson Beach, California, USA, over the two-week neap-spring tidal transition during both a wet and dry season. The microbial community, analyzed by 16S rRNA gene (V4) amplicon sequencing, clustered according to consistent physicochemical features found within STEs.

Organic ultraviolet filters (OUVFs) have been widely used as functional ingredients of sunscreen products and have entered into marine ecosystems, particularly in tropical areas where solar UV radiation is strong. These chemicals, with their potential toxicity and ecological risk, have raised widespread concern for the protection of the fragile marine ecosystem of coral reefs. In this study, fourteen OUVFs were analyzed among 24 coral species, together with their habitats including seawater and sediment from the coastal coral reef regions of Hainan Island, South China Sea.

With global climate warming and ocean acidification, mineral amendments in coastal areas have emerged as a promising strategy to bolster carbon sinks and alkalinity. However, most research has predominantly focused on carbon dioxide (CO) absorption, with limited exploration of methane (CH) reduction despite its more potent greenhouse effect. To address this gap, our study conducted a microcosm manipulative experiment employing coastal wetlands sediments to elucidate the regulatory effects of various mineral amendments on greenhouse gas emissions (including CO and CH) and seawater alkalinity.

Marine Research Institute, Chungnam National University, Daejeon 34134, Republic of Korea.
The elemental and isotopic (δCu and δZn) characteristics of 34 AFP samples from 5 paint manufacturers, the isotopic fractionation during the dissolution of AFPs by seawater, and the subsequent adsorption of isotopes onto coastal fine-grained sediments were investigated to identify potential indicators (metal ratios and isotopes). The δCu and δZn values for 34 AFPs could be divided into 2 groups regardless of the type of paint or manufacturer. Dissolution by seawater induced substantial fractionation but δCu and δZn approached the bulk AFP values when the leached fraction increased.
