Arsenic toxicosis and suspected chromium toxicosis were diagnosed in a herd of cattle that ingested ashes from lumber treated with copper, chromium, and arsenic. Findings included peracute death, depression, ataxia, weakness, recumbency, and watery diarrhea. Chemical analyses of liver, kidney, abomasal contents, rumen contents, and ashes revealed high concentrations of arsenic and chromium. Histologically, specimens of abomasum and duodenum had diffuse mucosal degeneration and engorged capillaries. Epithelial cells of the proximal convoluted tubules and distal collecting tubules of the kidney were swollen and had mild granular cytoplasmic degeneration. Burning lumber treated with copper, chromium, and arsenic does not remove the heavy metals from them, and ingestion of the ashes from the wood constitutes a hazard to livestock health.
在一群摄入了用铜、铬和砷处理过的木材灰烬的牛群中，诊断出砷中毒和疑似铬中毒。发现包括急性死亡、抑郁、共济失调、虚弱、卧地不起和水样腹泻。对肝脏、肾脏、皱胃内容物、瘤胃内容物和灰烬的化学分析显示，砷和铬的浓度很高。组织学上，皱胃和十二指肠标本有弥漫性黏膜变性和毛细血管充血。肾脏近端曲管和远端集合管的上皮细胞肿胀，有轻度颗粒状细胞质变性。燃烧用铜、铬和砷处理过的木材并不能去除其中的重金属，摄入木材的灰烬对家畜健康构成危害。
