Abstract

In the present study, the concentration of Cr, Cd, Cu, Zn, Pb, and As in various tissues of Hemibagrus sp. from two different
habitat were determined with microwave assisted digestion-inductively coupled plasma-mass spectrometry. The objective of this
research was to determine the differences between wild and cultivated in terms of heavy metal accumulation in muscle, liver and
gills tissues. The metals accumulation pattern relating types of tissue and elements as well as fish habitats were revealed by
principal component analysis. The results revealed that variation in metal accumulation pattern is strongly dependent on the type
of tissues. The results suggested that Cu, Zn, and Pb are highly associated with liver tissue while Cr and As with muscle and
gills. The differences in heavy metal accumulation observed between wild and cultivated Hemibagrus sp. were probably due to
the differences in their environmental conditions.
