Ecological Uptake and Depuration of Carbon Nanotubes by Lumbriculus variegatus
BACKGROUND Carbon nanotubes represent a class of nanomaterials having broad application potentials and documented cellular uptake and ecotoxicological effects that raise the possibility that they may bioaccumulate in living organisms. OBJECTIVES Radioactively labeled nanotubes were synthesized using a novel methane chemical vapor deposition procedure. Single-walled carbon nanotubes (SWNTs), m...
متن کاملBiological uptake and depuration of carbon nanotubes by Daphnia magna.
It is inevitable that carbon nanotubes (CNTs) will be released to and widely dispersed in environmental ecosystems, given their numerous expected applications. Determination of their potential for bioaccumulation by ecological receptors is thus critical. Previous, research involving several different terrestrial and benthic organisms has indicated that CNTs spiked to soils or sediments do not b...
متن کاملEffects of Carbon Amendments on Ecological Responses and Pcb Bioaccumulation in Lumbriculus Variegatus
Several studies have shown that sediment associated black carbonaceous particles can reduce aqueous and bioaccumulated concentrations of hydrophobic organic compounds (HOCs) in benthic organisms. Therefore, carbon amendments (e.g. activated carbon, AC) have been studied as stabilization method for contaminated sediments. However, it appears that the amendments may have also direct adverse effec...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولSludge reduction by lumbriculus variegatus in Ahvas wastewater treatment plant
Sludge production is an avoidable problem arising from the treatment of wastewater. The sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. Application of aquatic worm is an approach to decrease the amount of biological waste sludge produced in wastewater ...
