Concentrations of lead and cadmium were measured in the muscle of four fish species: pike, Esox lucius L., Eurasian perch, Perca fluviatilis L., roach, Rutilus rutilus (L.), and bream, Abramis brama (L.) collected from four lakes in the Olsztyn Lake District of northeast Poland. The fish were caught in the 1999-00 period. Heavy metals contents were determined using the flameless atomic absorption spectrophotometry method. The mean lead content in the muscle of pike, perch, roach, and bream was 0.084, 0.098, 0.094, and 0.083 mg/kg, respectively. Positive correlation coefficients were noted between Pb concentration and the body weight and total length of roach and perch. Negative correlation factors between Pb content and the body weight and length of pike and bream were noted. The mean content of cadmium in the muscle of pike, perch, roach, and bream ranged from 0.0023 to 0.0025 mg/kg. There were positive correlations between the levels of Cd in the muscle of roach and perch and body weight and total length
