FISH POLLUTION WITH HEAVY METALS

Camelia POPA, Petru BULAI

Abstract

The  aim  of  this  work  is  to  identify  and  to  find  the  concentration  of  some  heavy metals (Cr, Ni, Fe, Hg, Pb) of  different assortment of fish that we buy from markets: herring,
sprat,  hake,  pangasius,  trout,  broad  snout,  and  mackerel.  Heavy  metal  concentrations  were measured using EDX  and UV-VIS spectrometer techniques. Laboratory studies showed that
these  fishes  don’t  contain  Ni,  Hg,  Pb.  They  contain  only  Cr  and  Fe  but  the  concentration don’t’  exceed  the  maximum  admissible  limit  from  current  legislation.  Also,  heavy  metals
content in bone is higher than in meat. Hake species do not accumulate heavy metals in meat, but they accumulate in the bone, completely.
