Measurement of metallic particles extracted from the lung parenchyma of two electricians and one electrotechnician.

This paper reports the chemical nature of particles extracted from the lung parenchyma of two electricians and one electrotechnician. Results indicate that these workers retained particles that are qualitatively representative of their work history. The concentration of nickel in the lung of these workers was statistically higher (Mann-Whitney, p < 0.013) than the concentrations measured in the lungs of 39 other workers who died of different types of cancers.
