Description
Abstract
The occurrence of phthalate esters in
freshwater and marine aquacultural species like rainbow
trout Oncorhynchus mykiss and shi drum Umbrina
cirrosa, respectively, were determined by
immunohistochemical approach. The results showed a
similar distribution in the gastrointestinal tract of both
species. In particular, intense immunoreactivity was
found at gastric gland level. In the intestinal tract, goblet
cells failed to stain, whereas enterocytes showed the
highest binding of phthalates restricted to the apical
cytoplasm. This distribution of phthalate esters at gastric
gland and enterocyte level may have implications for the
physiology of the digestive process and intestinal
biotransformation. Phthalates are confirmed to be widely
diffused contaminants, absorbed via the alimentary
canal; thus a multidisciplinary approach could be useful
to examine sea and freshwater environments
