Biotransformation of the polycyclic aromatic hydrocarbon pyrene in the marine polychaete Nereis virens.
In vivo and in vitro biotransformation of the polycyclic aromatic hydrocarbon (PAH) pyrene was investigated in the marine polychaete Nereis virens. Assays were designed to characterize phase I and II enzymes isolated from gut tissue. High-pressure liquid chromatography measurement of 1-hydroxypyrene, pyrene-1-glucuronide, pyrene-1-sulfate, and pyrene-1-glucoside appeared to be a sensitive metho...
متن کاملAdenylate compartmentation and storage in coelomic cells of the polychaete Nereis virens
The concentrations of adenine nucleotides (AMP, ADP, ATP) were determined in coelomic cells (eleocytes) of the polychaete Nereis virens. In cells of immature and male animals, total ADP and AMP contents (each 10­15 µmol ml-1 packed cell volume) greatly exceeded that of ATP (0.8 µmol ml-1 packed cell volume). 31P-nuclear magnetic resonance (NMR) studies of living eleocytes showed...
متن کاملUptake pathways and subcellular fractionation of Cd in the polychaete Nereis diversicolor.
Polychaetes have often been utilized as indicator species to investigate the impacts of pollutants, such as heavy metals. The uptake of Cd by the polychaete Nereis diversicolor was determined at varying Ca concentrations and with pre-exposure to Ca ion channel blockers and metabolic inhibitors in simulated sea water over 1 week period. The supply of Ca in simulated sea water inhibited Cd uptake...
متن کامل1-Hydroxypyrene as a biomarker of PAH exposure in the marine polychaete Nereis diversicolor.
The possibility of using the pyrene metabolite 1-hydroxypyrene as a biomarker of polycyclic aromatic hydrocarbons (PAHs) exposure was investigated by exposure of the marine polychaete Nereis diversicolor to several PAHs in the laboratory. Animals were exposed to pyrene alone and to five different PAHs - phenanthrene, anthracene, pyrene, benzo[a]pyrene and benzo[k]flouranthene. After five days o...
متن کاملToxic effects and bioaccumulation of nano-, micron- and ionic-Ag in the polychaete, Nereis diversicolor.
There is increasing concern about the toxicities and potential risks, both still poorly understood, of silver nanoparticles for the aquatic environment after their eventual release via wastewater discharges. In this study, the toxicities of sediment associated nano (<100 nm)-, micron (2-3.5 μm)- and ionic (AgNO(3))-Ag on the sediment-dwelling polychaete, Nereis diversicolor, were compared after...
