The main circulatory medium of echinoderms is the coelomic fluid. Biochemistry of coelomic fluid is very complex and slightly different from seawater. The main aim of this research was to analyse concentration of electrolytes (potassium, calcium, magnesium, chlorine and sodium), heavy metals (lead, chromium, cadmium and cobalt) and iron in coelomic fluid of sea urchin, Arbacia lixula as an indirect indicator of seawater contamination. After precise statistical evaluation it was observed that electrolyte concentrations were; Na 189.20±11.41 mmol/l, Cl 134.06±37.08 mmol/l, Mg 4.24±1.08 mmol/l, Ca 3.04±0.84 mmol/l. Biochemical content of heavy metals in coelomic fluid was; Co 1.292±0.879 ppm, Pb 0.644±0.131 ppm, Cr 0.116±0.055 ppm, Cd 0.031±0.017 ppm and iron 0.259±0.058 ppm, and it depends on the potential accumulation level in the organism. The composition of electrolyte and heavy metal content varies depending on the composition of seawater. Obtained values are within the range of values most commonly found in low polluted areas of the Adriatic sea. Similar models may be applied for monitoring of heavy metal contamination in marine environment.
