A comparison of metal accumulation by the cnidarian Hydra vulgaris directly from water or [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2007
The cnidarian Hydra has been widely used to assess the acute toxicity of freshwater pollutants, but very little is known about pollutant accumulation by this animal.

Band Edge Reorganization via Symmetry Constraints in Covalent Bonding Heterojunctions Boosts Photocatalytic Metronidazole Degradation

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

Environmental concentrations of metals (Cu and Zn) differently affect the life history traits of a model freshwater ostracod

The European Zoological Journal
Zinc (Zn) and copper (Cu) are common contaminants of inland water bodies under severe anthropogenic pressure. The main aim of this study was to test the influence of environmental aqueous concentrations of Zn and Cu on the fitness-related life history ...

Bioconcentration as a key driver of Hg bioaccumulation in high-trophic-level fish [PDF]

Biogeosciences
The ability of monomethylmercury (MMHg+) to bioaccumulate in seafood is of concern due to its neurotoxic properties. The challenge in understanding MMHg+ bioaccumulation lies in the fact that its levels in higher trophic levels result from both ...

Bioconcentration Factor (BCF) and Translocation Factor (TF) of Heavy Metals in Mangrove Trees of Blanakan Fish Farm

Makara Journal of Science, 2017
In the mangroves of Blanakan, Indonesia, silvofishery practices may play a role in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials.

Bioconcentration and biotransformation of organophosphorus flame retardants (PFRs) in common carp (Cyprinus carpio)

Environment International, 2019
Understanding the bioaccumulation and biotransformation of xenobiotic compounds is critical for evaluating their fate and potential toxicity in vivo. In the present study, the tissue specific accumulation and depuration of seven organophosphorus flame ...
