During World War II, Mancuso co-founded organizations in public health, at health departments of Michigan and Oregon. After the war he headed the Department of Industrial Hygiene at the Ohio Department of Health. There, he produced the first American long-term mortality studies and showed how social security data could be used to understand deaths among factory workers.
One of his 1950s contracts, with the Philip Carey Manufacturing Company, was to study the occupational risk of asbestos.[6][7] After reporting that asbestos was harmful to both employees and customers, his contract was terminated.[7] As a result of his work, warning labels were added to asbestos insulation.[8]
In 1964, the Division of Biology and medicine of the Atomic Energy Commission (AEC) asked Mancuso of the possibility of long-term effects of low levels of ionising radiation.[6] The following year they granted him a five-year contract to investigate the effects of low-level radiation on half a million workers employed in a nuclear weapons plant.[6][8] This he felt could only be done by long-term follow-up; by looking at old records and following the group of people through to death to find out what they died from.[6][8] When in 1974 the AEC asked Mancuso to dispute findings that low-level radiation did not cause cancer, Mancuso refused, and his contract was later terminated.[6][9][10] He took to independent research with epidemiologist Alice Stewart and mathematician George Kneale.[6][11] In 1977 they revealed that Hanford Nuclear Weapons Plant employees were "dying of cancer from cumulative radiation exposures far below the standards established as safe".[8][12][13] In response, in 2000 the US Government agreed to offer compensation to those affected.[8][3]
Beryllium
In 1970, Mancuso published his study that concluded that beryllium-associated pneumonitis and bronchitis was related to subsequent development of lung cancer.[14][15] This is generally considered the first recognition of a link between beryllium and cancer.[3] Ten years later, he confirmed his findings in a follow-up study.[14]
Viscose
In a 1972 paper, Mancuso had traced employment records from 1938 at the Industrial Rayon Corporation, to study neuropsychiatric effects of carbon disulfide, used in producing viscose.[16] He found a likely under-reporting of deaths by suicide, including one where the wife was murdered prior to suicide.[16] Later, the National Institute for Occupational Safety and Health hired him to expand on the study to include the deaths from heart disease.[16] The result was a long paper titled "Epidemiological study of workers employed in the viscose rayon industry".[16] In it he demonstrated the risk from coronary heart disease among those employed in the rayon industry increased by 40% in those employed for more than ten years.[16]
Mancuso continued to investigate occupational hazards after his retirement.[3] He is credited as the first to understand a link between chromium and cancer.[3] His 1997 paper based on the follow-up of 332 chromate production workers hired at the same industrial plant from 1931 to 1993, concluded that all types of chromium were carcinogenic.[18]
Honors and awards
In 1961 the National Cancer Institute awarded Mancuso a career award.[5]
Death
Mancuso died from oesophageal cancer on July 4, 2004, in Oakland, California.[8] He was survived by his wife Rafaella, two daughters and one son.[3]
