Animal lead poisoning (also known as avian plumbism, or avian saturnism for birds) is a veterinary condition and pathology caused by increased levels of the heavy metal lead in animal's body. Lead interferes with a variety of body and natural processes. It is toxic to many organs and tissues including the heart, bones, intestines, kidneys, and reproductive and nervous systems. It mainly affects the haematopoietic system. It also affects the sulfhydryl group containing enzymes and also thiol content of erythrocyte. It inhibits the enzyme delta amino levaminic acid dehydrogenase enzyme(ALA) which is present in the rbc. It is therefore particularly toxic to young animals, mainly dogs and cattle. As in humans, ''animal lead poisoning'' may be acute (from intense exposure of short duration) or chronic (from repeat low-level exposure over a prolonged period). Acute intoxication can quickly lead to death. ==Prevalence== Lead is now a common environmental pollutant. For the birds, a commons source is lead shot, eaten as grit. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Animal lead poisoning」の詳細全文を読む スポンサード リンク
