Özet

Tinca tinca were exposed to lethal and sublethal treatments with mercury, cadmium and lead for acute and chronic periods to study alterations in immunological parameters. Acute lethal exposure (Lc(50)/48 h; 96-h Lc(50) of Hg 1.0, Cd 6.5, Pb 300 ppm) caused a significant increase in Lct in the Hg treatment and a significant decrease in the Pb treatment, and a significant decrease in total WBC count in the Hg and Cd treatments. Lower acute sublethal exposures (10% Lc(50)/24 h), caused a significant increase in Lct in the Hg and Pb, treatments and a significant increase in total WBC count in the Hg treatment. The same concentration after 96-h exposure resulted in a significant increase in Lct in all 3 treatments and a significant decrease in total WBC count in the Cd treatment, and after chronic exposure caused a significant increase in Lct in the Hg treatment and a significant increase in total WBC count in the Hg and Cd treatments. Higher acute sublethal exposures (25% LC50/24 h) caused a significant increase in Lct in the Hg and Cd treatments and a significant increase in total WBC count in all 3 treatments. The same concentration after 96-h exposure caused a significant increase in both Lct and total WBC count in all 3 treatments, and after 3 weeks exposure resulted in a significant increase in Lct in the Hg treatment and a significant increase in total WBC count in the Hg and Pb treatments and a significant decrease in the Cd treatment.
