关于铅对染色体畸变的作用,目前尚有些争议。Muro等将含1％醋酸铅的食物喂小鼠二周,发现骨髓细胞染色体畸变率增高;小泉明等给大鼠饮用含500和5,000ppm醋酸铅的水九周后发现给铅组的大鼠外周血淋巴细胞染色单体畸变率增高;但Leonard等给小鼠饮用含1克/升铅的水九 The role of lead in chromosomal aberrations is still somewhat controversial. Muro and other 1% lead acetate in mice fed two weeks and found that chromosome aberrations in bone marrow cells increased; Koizumi Ming and other rats with drinking water containing 500 and 5,000ppm lead acetate nine weeks after the discovery of the lead group of rat peripheral blood Lymphocyte staining monomer aberrations increased; but Leonard and other mice to drink with 1 g / L of lead in water nine
