Histopathological examination of lungs by light microscopy, and measurement of the number of alveolar microphages available by a standard washing procedure, for animals subjected to inhalation of soluble and insoluble aerosols of lead or nickel, Pb-C12, Pb2-03, Ni- C12, and NiO, near or below the levels proposed as acceptable for occupational exposures. The number of available macrophages increased for NiO, decreased for Pb2-03, and was not changed for Pb- Cl2, and Ni-Cl1. However, distribution in cell sizes varied with exposure. Observed histopathological changes from nickel compounds are cited as requiring a lowering of the threshold limit value for nickel and nickel compounds.
