Seven Florida sandhill cranes (Grus canadensis pratensis) and 6 greater sandhill cranes (Grus canadensis tabida) were exposed to lead-base paint containing 27% lead. One bird of each subspecies died enroute to the hospital, with a clinical history of anorexia, weakness, and open-mouth breathing of 36 hours' duration. There were no gross lesions, and microscopic lesions were limited to focal hepatic necrosis and hemosiderosis. Two of each subspecies of cranes developed clinical signs of lead poisoning, which included anorexia, weakness, green diarrhea, regurgitation, and open-mouth breathing. Diagnosis of lead poisoning was confirmed on the basis of blood lead concentrations ranging from 146 microgram/100 ml to 378 microgram/100 ml. These 4 cranes were treated successfully with calcium disodium edetate intramuscularly. Seven of the birds remained clinically normal despite high blood lead levels, especially in the greater sandhill cranes.
七只佛罗里达沙丘鹤（加拿大鹤佛罗里达亚种）和六只大沙丘鹤（加拿大鹤大沙丘鹤亚种）接触了含铅量为27%的铅基涂料。每个亚种各有一只鹤在送往医院途中死亡，临床症状为厌食、虚弱以及持续36小时的张口呼吸。没有明显病变，微观病变仅限于局灶性肝坏死和含铁血黄素沉着症。每个亚种各有两只鹤出现铅中毒的临床症状，包括厌食、虚弱、绿色腹泻、反流和张口呼吸。根据血铅浓度在146微克/100毫升至378微克/100毫升之间，确诊为铅中毒。这4只鹤通过肌肉注射依地酸二钠钙成功治愈。尽管血铅水平很高，但仍有7只鹤临床症状正常，尤其是大沙丘鹤。
