永城煤矿塌陷区水污染对鲫鱼外周血细胞数量的影响

选用鲫鱼(Carassius auratus)为研究对象,以相对无煤矿污染的商丘天沐湖为对照,以煤矿污染较严重的永城煤矿塌陷积水区为研究样地,研究永城煤矿塌陷区水质对鲫鱼外周血细胞数量的影响。结果表明:与对照天沐湖相比,永城煤矿塌陷区样地鲫鱼的红细胞数量极显著增加(P<0.01),但白细胞数量差异不显著(P>0.05);从白细胞分类计数统计结果看,淋巴细胞极显著增加(P<0.01),血栓细胞极显著减少(P<0.01),单核细胞显著减少(P<0.05);嗜中性粒细胞虽有减少,但两地差异不显著(P>0.05)。总之,永城煤矿塌陷区水污染已造成鲫鱼外周血细胞数量发生明显改变。

Changes of the Peripheral Blood Cell Quantity of Carassius auratus in Yongcheng Waterlogged Area Caused by Mining Coal

To study the effects of Yongcheng waterlogged area caused by mining coal on the morphological characteristics in Carassius auratus,the fishes were caught from the Tianmuhu in Shangqiu(TMHS),a relatively unpolluted area which was used as a control and Waterlogged area caused by mining coal in Yongcheng(WAMCY),a heavier polluted area compared to TMHS.The results showed that compared to the control area,the numbers of erythrocytes was significantly higher(P<0.01) while the total numbers of leucocytes were not significant(P>0.05).The lymphocytes increased significantly(P<0.01),while the thrombocytes(P<0.01) and monocytes(P<0.05) decreased obviously in WAMCY.However,the neutrophils showed the tendency to decrease in WAMCY but the difference was not significant(P>0.05) between the two sampled areas.The results suggest that the mining coal pollution at aquatic environmental level in WAMCY has caused obvious alterations of the numbers of peripheral blood cells in C.auratus.
