Records were reviewed of horses that had fatal injuries at California racetracks over a 16-mo period. Horses were categorized based on injury type, sex, age and breed. Arsenic, cadmium, copper, iron, lead, molybdenum and zinc concentrations were measured in the liver and kidneys from each horse. Arsenic and lead were not detected in any tissues. Liver heavy metal concentrations were not related to the injury type. Kidney iron concentrations were significantly (P < 0.05) higher in horses with ligament ruptures and in horses with fractured sesamoid, carpus or metacarpus/metatarsus bones. Liver cadmium, kidney cadmium, and liver iron were higher (P < 0.05) in horses > 2 y old than in 2-y-olds. Liver cadmium concentrations were higher (P < 0.05) in Thoroughbreds than in Quarter Horses.
对加利福尼亚赛马场在16个月期间内遭受致命伤的马匹记录进行了审查。根据损伤类型、性别、年龄和品种对马匹进行分类。测定了每匹马肝脏和肾脏中的砷、镉、铜、铁、铅、钼和锌浓度。在任何组织中均未检测到砷和铅。肝脏重金属浓度与损伤类型无关。韧带断裂以及籽骨、腕骨或掌骨/跖骨骨折的马匹肾脏铁浓度显著更高（P < 0.05）。2岁以上马匹的肝脏镉、肾脏镉和肝脏铁含量高于2岁马匹（P < 0.05）。纯种马的肝脏镉浓度高于夸特马（P < 0.05）。
