The influence of water chemistry on characterised polyvinyl pyrrolidone- (PVP-) coated silver nanoparticles (81 nm) was investigated. NaCl solution series of 100-800 mg L(-1) lead to initial and temporal increase in nanoparticles size, but agglomeration was limited. pH variation (5-8) had only minor influence on the hydrodynamic particle size.

Silver nanoparticles are utilised in an increasing amount of products, and discharge to the aquatic environment is inevitable. Fish gills are in direct contact with the ambient water, making them potential exposed and vulnerable to suspended silver nanoparticles. The present study investigates the effect of silver nanoparticles (average 81 nm) on the oxygen(More)
Development of male zebrafish (Danio rerio) courtship behavior was studied following estrogenic disruption of sexual differentiation. Sixty zebrafish were exposed at 28 degrees C to 5 ng/L (nominal concentration) of 17alpha-ethinylestradiol (EE2) from the egg stage until adulthood at four months of age, resulting in a female-biased sex ratio. Twenty-five(More)
The present study investigates the effect of silver nanoparticles on olfaction in Crucian carp (Carassius carassius) and Eurasian perch (Perca fluviatilis). The electro-olfactogram (EOG) signal was recorded by stimulating the olfactory epithelium with pulses of the odorant L-alanine during the pre-exposure, silver exposure and recovery periods,(More)
