S Katharine Hammond

In the 1980s Hammond demonstrated a device to monitor the health impacts of passive smoking.^[5] The device monitored the diffusion of nicotine to a filter treated with sodium bisulfite.^[6] The nitrogen is desorbed from the filters and subsequently analysed using gas chromatography.^[6] She demonstrated that non-smokers working in the same room as smokers were exposed to the same amount of carcinogen benzene as smokers inhale in six cigarettes.^[5] She provided expert testimony before the Occupational Safety and Health Administration.^[5][7] Her research and reporting to the Federal government of the United States resulted in the Federal Aviation Administration issuing a ban on smoking on aeroplanes.^[1] She indicated that a smoking ban in correctional facilities significantly improved the health of non-smoking prisoners by reducing their exposure to secondhand smoke.^[8] She also showed pregnant women who smoke transfer carcinogens through the placenta to their unborn children, increasing their risk factors for different cancers.^[5] Whilst in Massachusetts, Hammond encouraged parents to monitor their children's exposure to secondhand smoke, and used their findings as a means to motivate parents to stop smoking.

Alongside her research program into the impacts of first and secondhand smoke, Hammond studied how industry employees were impacted by their work environments.^[5] She showed that in the semiconductor industry, women working with certain solvents were 40 – 90% more likely to have spontaneous abortions than the general population.^[5] Her research informed several health policies to improve health and safety within research and development facilities.^[5]

In 1995 she moved from the University of Massachusetts Medical School to join the UC Berkeley School of Public Health.^[5][9] At Berkeley Hammond leads the national Children's Health and Air Pollution study, which looks to understand and minimise the risks of air pollution on children's health in Fresno, California.^[10] Fresno has been identified as one of the eight most polluted cities in the United States.^[11] Her work showed that there is a direct link between pollution and children's immune systems; and that polycyclic aromatic hydrocarbon impacted Regulatory T cell function.^[11][12] She has looked at whether air pollution impacts the risk of premature birth and birth defects, whether air pollution causes allergies, how it impacts metabolism and obesity and how transit patterns impact foetus development in pregnant women.^[13] Amongst her research programs, she studies the impact of lead on the levels of lead in construction worker's blood and the impact of agrochemicals on the health of farmers.^[14] She has shown that smoking Hookah can be as damaging to the lungs as the smoking cigarettes.^[15]
