喷气发动机燃料中所含的各种金属逸散到空气中,是构成大气污染的重要因素之一。为此,作者对生活在机场区和非机场区狗体中一些金属的含量进行了比较 20只3～6岁的狗分成二组每组10只。第一组在邻近大阪国际机场处捕捉;第二组在机场西南约7公里的西宫市捕捉。两组狗在麻醉下宰杀,取血液、心脏、肺、肝、肾、脾和肋骨作七种金属(铝、铜、铅、锰、镍、钒和锌)的分析。结果,肉眼检查两组的器官无显著差别。两组狗组织中金属含量如表所示。肋骨中的铅含量最高,其后依次是肝、肾、脾、肺、心和血液。肾和血液中的铅含量两组间有显著差别。第一组中有一只狗其组织中铅含量:(μg/g
Jet fuel contained in the various metals contained in the air escaping into the air, constitute an important factor in air pollution. To this end, the authors compared the levels of some metals in dog bodies living in airport and non-airport zones. Twenty dogs, ages 3-6, were divided into two groups of 10 animals each. The first group is captured at the neighboring Osaka International Airport; the second group is captured at Nishinomiya City, about 7 km southwest of the airport. Two groups of dogs were killed under anesthesia and blood, heart, lung, liver, kidney, spleen and ribs were analyzed for seven metals (aluminum, copper, lead, manganese, nickel, vanadium and zinc). As a result, there was no significant difference in macroscopic examination of organs in both groups. The metal content of the two groups of dogs is shown in the table. Ribs in the highest lead content, followed by the liver, kidney, spleen, lungs, heart and blood. There was a significant difference between the two groups in lead levels in kidney and blood. In the first group there was a dog whose lead content in the tissues: (μg / g
