Dr. Y. Thangam ^[11] | Dr. S. Umavathi | V. B. Vysakh

Abstract: This study represents the changes in the toxicant inorganic mercury. Inorganic mercury, have been reported to develop a disorder called acrodynia or pink disease. Symptoms includes leg cramps, irritability, redness and peeling of the skin of hands, nose, and soles of the feet. Itching, fever, sweating, salivating, rashes (including baboon syndrome rashes in the buttocks, anal and genital regions), sleeplessness and/or weakness. Additional reports indicate the effects of inorganic mercury in children and adults include kidney damage and digestive tract problems including diarrhea, nausea, and ulcers. Table 1. Represent the data on changes in the hemoglobin content of the fish Cyprinus carpio exposed to sublethal concentration of mercury for 35 days. The hemoglobin content in the mercury exposed fish were found to be decreased when compared to the control showing a percent decrease of -40.22, -40.00, -37.58, -31.00, -40.51 at the end of 7, 14, 21, 28, 35 days. Table 2. Reveal the changes in red blood cell count of the blood of fish Cyprinus carpio exposed to sublethal concentration of mercury exposed fish for 35 days. The RBC count was decreased throughout the study period when compared to the control group showing a minimum percent decrease of -4.63 at the end of 7th day and a maximum percent decrease of -16.66 at the end of 35th day. Decrease in RBC count in mercury exposed for 7th, 14th, 21st, 28th, and 35th days, the percent observed was -4.63, -14.77, -11.17, -4.66, -16.66. Changes in the leucocytes count of fish Cyprinus carpio exposed to sublethal concentration of mercury for 35 days were presented in Table 3. During the above exposure period WBC count were decreased at 7th, 14th, days showing a percent decrease of -3.28, -2.87 and at the end of 21st, 28th and 35th days WBC count increased showing a percent increase of 4.56, 10.00, 8.63 respectively.
