Article
Full-text available
Differences in metal bioaccumulation among species make it difficult to compare biomonitoring results obtained using different marine bivalve species. To address this challenge and improve the interpretation of biomonitoring data, we studied the toxicokinetic mechanisms underlying these differences and developed a method to estimate seawater metal...

Polycyclic aromatic hydrocarbons (PAHs) are pervasive pollutants in the environment. To compare the developmental toxicity of PAHs with different ring numbers to fish embryos, benzo(a)pyrene (BaP), pyrene (Pyr) and phenanthrene (Phe) were selected as the representatives of 3, 4 and 5-ringed PAHs, and fertilized embryos of zebrafish (Danio rerio) we...
Article
The application of bioavailability-based risk assessment for the management of contaminated sediments requires new techniques to rapidly and accurately determine metal bioavailability. Here, we designed a multimetal isotopically modified bioassay to directly measure the bioavailability of different metals by tracing the change in their isotopic com...

Polycyclic aromatic hydrocarbons (PAHs) are pervasive pollutants in the environment. To compare the developmental toxicity of PAHs with different ring numbers to fish embryos, benzo(a)pyrene (BaP), pyrene (Pyr) and phenanthrene (Phe) were selected as the representatives of 3, 4 and 5-ringed PAHs, and fertilized embryos of zebrafish ( Danio rerio )...
Article
The ubiquity of microplastics in the environment has attracted much attention on their risks. Though newly produced plastics were considered inert to aqueous metals, a few studies suggest aged microplastics can accumulate metals. Still, knowledge gap exists on the comparability of metal accumulation in field condition and that acquired in controlle...
Article
Phenanthrene (Phe) is a representative polycyclic aromatic hydrocarbon, and its ubiquity makes the risk assessment of Phe in aquatic ecosystems important. To assess the long-term effects of early-life Phe exposure on fish, the embryos of the model organism, zrbrafish (Danio rerio) were exposed to Phe at 0.05, 0.5, 5 and 50 nmol/L for 96 h and then...
Article
In estuaries, salinity fluctuates rapidly and continuously, greatly affecting the bioavailability and thus toxicity of contaminants, especially metals, causing difficulties in deriving site-specific water quality criteria. We developed a method for predicting the toxicity of the metal cadmium (Cd) in estuarine waters of any salinity fluctuation sce...
Article
Intertidal bivalves are periodically exposed in air. It is tempting to speculate that the organisms would temporarily escape from contaminants when they are out of water and thus have lower risks. In this study, we tested this speculation by investigating cadmium (Cd) toxicokinetics in an intertidal mussel, Xenostrobus atratus, under the effects of...
Article
Salinity has considerable effects on the toxicity of metals in estuarine waters. The effects of salinity are manifold, making it difficult to summarize for risk assessments. In this study, we separated and quantified the multiple effects of salinity on cadmium (Cd) in a toxicokinetic-toxicodynamic framework. The estuarine clam, Potamocorbula laevis...
Article
It is widely accepted that the most abundant polycyclic aromatic hydrocarbons (PAHs) in weathered crude oils is cardiotoxic. Although PAHs toxic endpoints show strong correlation with the aryl hydrocarbon receptor (AhR), a ligand activated transcription factor, and is thought to be a potent inducer of cytochrome P4501A, the action mechanism of PAHs...
Article
Sebastiscus marmoratus larvae were exposed to waterborne polycyclic aromatic hydrocarbons (PAHs) containing 3-5 rings, benzo[a]pyrene (BaP), pyrene (Py) or phenanthrene (Phe), respectively at 0.01, 0.1 and 1 μg L⁻¹. Cumulative mortality, frequency of dorsal curvature and rate of pericardial and yolk sac edema in larvae treated for 8 days were signi...

Tributyltin (TBT) is a ubiquitous marine environmental contaminant characterized primarily by its reproductive toxicity. However, the neurotoxic effect of TBT has not been extensively described, especially in fishes which have a high number of species in the marine environment. This study was conducted to investigate the neurotoxic effects of TBT a...
Article
Pagrosomus major larvae were exposed to the water-soluble fraction of hydrocarbon in No.0 diesel oil (corresponding to No.2 fuel oil) at concentrations of 0, 0.17, 1.22 and 8.82 mg/L for up to 15 days. Larvae were sampled on days 9 and 15 of the experiment. Supernatants of viscera tissue extractions were assayed for biochemical response in terms of...
