Abstract :This study detected eight heavy metal insert ignore into journalissuearticles values(Cu, Pb, Zn, Ni, Mn, Fe, Cr, Al); and one metalloid insert ignore into journalissuearticles values(As); amounts in the sediment of Meyil Lake. The findings obtained were compared with the limit values of sediment quality guidelines insert ignore into journalissuearticles values(SQGs); such as PEL insert ignore into journalissuearticles values(probable effect level);, TEL insert ignore into journalissuearticles values(threshold effect level);, ERL insert ignore into journalissuearticles values(effects range low); and ERM insert ignore into journalissuearticles values(effects range median);. In addition its probable toxic effects were investigated via different sediment evaluation methods. As a result, the value of the metal concentrations tested was below the limit value. The contamination factor of all the metalinsert ignore into journalissuearticles values(loid);s tested was found to be below 1 insert ignore into journalissuearticles values(C_f^i<1);. Also the mean ERM quotient insert ignore into journalissuearticles values(m-ERM-q); and mean PEL quotient insert ignore into journalissuearticles values(m-PEL-q); values revealed that there was no risk for the lake. The total toxic unit insert ignore into journalissuearticles values(Σ TU); method revealing the toxic effect of the metalinsert ignore into journalissuearticles values(loid);s, also supported this result. The accumulation relations of metals insert ignore into journalissuearticles values(loids); are also revealed by correlation analysis.
