In 28 consecutive cases of urban dwellers who died in New York city, electron microscopy showed chrysotile asbestos to be present in all examined (28 of 28). Of these, possibly four of 28 may have been made "positive" by the occurrence of background fibril contamination. It is noteworthy that asbestos bodies were found in three of four of these "negative" cases. Chrysotile asbestos often occurred in association with other substances, including platy particles (clay or talc), fibrous glass, and, occasionally, diatoms. Data shows that chrysotile fibers and fibrils are present in the lungs of New York City residents. Similar observations have been reported for London, and it is expected that other major cities share this problem.
