作者对甲状腺肿和饮水的关系问题上,提出了一种新的理论,认为甲状腺肿和是由于饮用了含有由动物排泄物所状成的毒物的饮水所致。用硝酸银可把这种毒物沉淀,最后形成尿色素。作者指出,从几个地区的材料证明,甲状腺肿和水中碘含量无关。而甲状腺肿地区的饮水中却含大量的硝酸盐,其它污染指标也高,尿色素则都在2.5毫克/升以上。从动物实验证明稀的败血浆水和粪坑水可使动物引
On the issue of the relationship between goiter and drinking water, the authors propose a new theory that goitre is caused by the drinking of drinking water containing poisons formed by animal waste. With silver nitrate can precipitate this poison, the final formation of urinary pigment. The authors note that materials from several areas have shown that goiter and iodine in water are unrelated. The goiter area drinking water contains a lot of nitrate, other pollution indicators are also high, urine pigment are at 2.5 mg / l above. Animal experiments have shown that dilute stained plasma and cessation of water can cause animals cited
