Occupational exposure to elemental constituents in fingerprint powders.
Fingerprint detection is an essential component of any crime detection agency. Little information is available regarding the elemental constituents of powders that are available currently. One recent case of lead poisoning coupled with many complaints from the Vancouver identification Squad members initiated a study regarding the elemental composition of, and the occupational exposure to, these powders. Multi-elemental analysis of the powders investigated showed that all contained varying amounts of aluminum, calcium, zinc, iron, magnesium, manganese, and nickel. One powder, however, contained 41% lead. The time spent at the scene of crime during a normal working shift averaged 95.5 min. Assessment of inhalation exposure during this period by personal air sampling pumps never exceeded the occupational exposure standards for these elements. Secondary exposure from dust-contaminated police vehicles and clothing can be an important contributor to overall exposure.
