Effects on Lethal Concentration 50%, Hematological Parameters and Plasma Components of Crucian carp, Carassius carassius Exposed to Waterborne Zinc
수인성 아연 급성 노출이 붕어, Carassius carassius의 반수치사농도, 혈액학적 성상 및 혈장 성분에 미치는 영향
Abstract
Crucian carp, Carassius carassius (Weight 42.4 ± 9.0 g, Length 15.0 ± 1.0 cm) were exposed to waterborne zinc at 0, 5, 10, 20, 40 and 80 mg Zn2+/l for 96 hours. The lethal concentration 50 (LC50) at 96 hours of crucian carp, C. carassius exposed to waterborne zinc was 51.58 mg Zn2+/l. In hematological parameters, the RBC count was significantly decreased in the concentration of 40 mg Zn2+/l at 48 hours, whereas the hematocrit was significantly increased by zinc exposure. The MCV (mean corpuscular volume) (μl) and MCH (mean corpuscular hemoglobin) (pg) were significantly increased in the concentration of 40 mg Zn2+/l at 48 hours. The plasma components such as calcium, magnesium, glucose, cholesterol, total protein and ALT (Alanine aminotransminase) were significantly changed by zinc exposure. The results of this study suggest that the zinc exposure to C. carassius induced the significant physiological changes in the hematological parameters and plasma components as toxicity.
붕어(무게 42.4 ± 9.0 g, 길이 15.0 ± 1.0 cm)를 96시간 동안 0, 5, 10, 20, 40 및 80 mg Zn2+/l의 수 인성 아연에 노출시켰다. 수인성 아연에 노출된 붕어의 96시간 반수치사농도(LC50)는 51.58 mg Zn2+/l였다. 혈액학적 지표에서 48시간에 40 mg Zn2+/l 농도에서 RBC 수치가 유의하게 감소 한 반면, 헤마토크릿은 아연 노출에 의해 유의하게 증가하였다. MCV (μl)와 MCH (pg)는 40 mg Zn2+/l 농도에서 48시간에 유의하게 증가하였다. 칼슘, 마그네슘, 포도당, 콜레스테롤, 총 단백질 및 ALT와 같은 혈장 성분은 아연 노출에 의해 크게 변화되었다. 본 연구의 결과는 붕어에 대한 아연 노출이 독성으로서 혈액학적 매개변수 및 혈장 성분의 유의한 생리학적 변화를 유발함을 시사한다.
