We use the shallow estuary, Odense Fjord, Denmark, as a case study to test our hypotheses that (1) shifts in benthic fa...

The widespread pollution from the release of microfibers is an emerging concern as they are a potential threat to environment. Their identification in samples terms quantity and pathways remain challenge contamination can be major source error. A systematic study synthetic (MFs) has been carried out different environmental compartments urban area surface waters northwestern Mediterranean. quant...

Heat-shock proteins are a multigene family of proteins whose expression is induced by a variety of stress factors. This work reports the cloning and sequencing of HSP70 and HSP90 cDNAs in the gastropod Haliotis tuberculata. The deduced amino acid sequences of both HSP70 and HSP90 from H. tuberculata shared a high degree of homology with their homologues in other species, including typical eukar...

An intracellular bacterium Candidatus Xenohaliotis californiensis, also called Withering-Syndrome Rickettsia-Like Organism (WS-RLO), is the cause of mass mortalities that are the chief reason for endangerment of black abalone (Haliotis cracherodii). Using a real-time PCR assay, we found that a shore-based abalone farm (AF) in Santa Barbara, CA, USA discharged WS-RLO DNA into the ocean. Several ...

Mercury, with its reactive forms being the most deleterious for the trophic chains, has been identified as a major pollutant in a few confined bodies of the coastal zone. Due to feeding, burrowing, and bioirrigation activities, infauna are known to play a crucial role in the biogeochemical processes of contaminants. The main goal of the present study is to evaluate the effects of Hediste divers...

Estuary and coastal environments are a ‘‘sink’’ for contaminants, including manufactured nanomaterials (MNMs) (Klaine et al. 2008). MNMs may enter the marine environment via rainwater, wastewater, and river transportation. Harbor handling may also result in MNM leakage and deposition in harbor areas. Dumping wastes such as nanowaste, trash containing MNMs, and harbor-dredging, mudcontaining MNM...

The marine environment is becoming increasingly contaminated by environmental pollutants with the potential to damage DNA, with marine sediments acting as a sink for many of these contaminants. Understanding genotoxic responses in sediment-dwelling marine organisms, such as polychaetes, is therefore of increasing importance. This study is an exploration of species-specific and cell-specific dif...
