摘要
本文报道了钨矿开发区周围的农田,因受尾砂水污染而严重地危害畜禽健康。研究证明尾砂水中所含有害物质主要是钼与镉。畜禽因采食污染区生产的富含钼、镉的饲料而致病。牛对钼最易感,其中水牛还由于镉的作用而引起皮肤发红,呈现特异的“红皮白毛症”。推广口服硫酸铜,解除了全部耕牛所受危害。猪、鸭在镉、钼作用下,发生隐性慢性镉中毒,因镉引起动物缺硒、缺锌而在组织上呈现相应病变,兼有由镉直接刺激血管内膜所引起的血管壁增厚等病变。
In this paper the adverse effects on animals and poultry due to the contamination of farmland by the tailing water around the wolfram ineval selecting plant was reported. The study proved that the major harmful material in tailing water was Mo and Cd. The animal and poultry eating the feeds produced in polluted area developed diseases. Cattle are the most susceptible to Mo and showed mainly Mo poisoning. Buffalo cattle showed the special Syndrome of Red Skin and White Hair because of the effect of Cd. The morbidity and mortality rates of the disease were very high. About 10000 head of cattle were damaged per year only in Dayu county. The popularization of oral administration of copper sulphate could eliminate the damage of the disease to cattle. Pigs and ducks developed recessive chronic Cd poisoning under the effect of Cd and Mo and showed the histological lesions of Se-deficiency and Zn-deficiency and the thicken wall of blood vessel caused by the direct stimulus to blood vessel of Cd.
