In the period from 2007 to 2009 th year, the heavy metal concentration (Pb, Cd,? s? Hg) in carp, barbell, catfish and silver carp's muscular tissue, bones and internal organs was examined on three locations in the accumulation Strezevo in the Republic of Macedonia According to Rulebook of maximum allowed quantities of pesticides, metals and metalloid and other toxic substances in the Republic of Macedonia, in our examined samples the concentration of all examined toxic elements was under maximum allowed limits, except lead and cadmium in the following samples: (carp's bones, silver carp's internal organs) on location 3 in accumulation Strezevo in the Republic of Macedonia where lead concentration was 1.07 and 1.81. Cadmium concentration was also increased on the same location in the samples of carp's, silver carp's and barbel's bone tissue as in silver carp's internal organs. Also the concentration of examined insecticides in all samples were significantly under maximum allowed quantities. The results from our examinations have shown that the above mentioned locations in accumulation Strezevo in the Republic of Macedonia are relatively unpolluted. However, for more realistic ecological picture the number of analised samples should be increased.
