为研究用高砷煤烘烤的玉米粉的毒性，用高砷煤烘烤玉米粉饲喂小白鼠，小白鼠出现砷中毒症状，于第１５天全部死亡。病理检查显示实验小白鼠的器官和组织有严重损害，组织含砷量显著高于对照组。含量由高到低分别为皮毛、心肺、肝脏、肠、骨肉。实验提示，食用高砷煤烘烤的粮食制做的食物，是导致慢性砷中毒的重要因素。

Toxicity of corn powder baken on coal with high content of arsenic was studied. The mice were fed with the testing corn powder and appeared to be arsenic poisoning, died fifteen days later. The organs and tissue were heavily damaged. The arsenic content in tissue was significantly higher than control group, showing that skin>cardiopulmo>liver>intestine>skeleton and muscle.
