In fishes, accumulation of lead in various tissues (Linde et al. 2004; Ashraf 2005; Spokas et al. 2006; Schmitt et al. 2007; Has-Schon et al. 2008) and alterations in biochemical and hematological parameters (Ates et al. 2008) have been reported.
But in case of LPE-exposed fish, significant accumulation of Cr was noticed in most of the tissues (Table 2).
Silver nanoparticles are also known for genotoxicity and cytotoxicity in fish including accumulation in gill tissues and lysosomal destabilization in adult oysters.
While we propose that gadusol is synthesized de novo by the fish, the accumulation of MAAs in fish would still appear to be of dietary origin.
By reducing the size of the oil droplets and increasing the aromatic hydrocarbon concentration, one would suspect that the dispersed fraction is more bioavailable to fish for accumulation via the gills and oral uptake [ 19].
However, compared to the control fish, a rapid accumulation of trace metals in gills was observed.
Kita-GFP-RAS fish develop an accumulation of melanocytes at the level of the caudal fin that often cause disruption of normal tissue surrounding these lesions that we call melanocytic hyperplasia (figure s1) starting from 2 weeks post fertilization.
These compounds have also been found in marine fish, where their accumulation is thought to be of dietary or symbiont origin.
Jezierska and Witeska (2006) concluded that the difference in the amounts of various metal ion accumulation in fish body result from different affinity of metals to fish tissues, different uptake, deposition, and excretion rates.
