Abstract
The concentrations of 13 trace metals in 17 discrete anatomic sites of 11 pig hearts have been determined by emission spectrometry. The metals determined were copper, manganese, molybdenum, zinc, chromium, nickel, cesium, barium, strontium, cadmium, aluminum, tin, and lead. Anatomic sites sampled included aorta, main pulmonary artery, right superior vena cava, tricuspid valve, mitral valve, pulmonary valve, aortic valve, right atrium, left atrial appendage, right ventricle (free wall), left ventricle (free wall), left ventricle-papillary muscle, interventricular septum, crista supraventricularis, sinus node, atrioventricular node and His bundle, and left bundle branch. Statistical analysis of the data incorporated a multivariate analysis of variance and a Duncan analysis. The results showed that certain tissues of the cardiovascular system have distinctive trace metal contents.
