Benjamin Ferris (physician)
Benjamin Greeley Ferris, Jr. (24 January 1919 – 1 August 1996) was an American physician and epidemiologist, a professor at Harvard School of Public Health who helped to pioneer statistical studies into the health effects of air pollution in the United States in the 1960s and 1970s. In the early 1960s, Ferris and colleague Donald O. Anderson carried out the first large-scale statistical study in the United States linking cigarette smoking to respiratory disease. In 1973, Ferris and Frank E. Speizer launched a statistical study comparing air pollution in six urban areas of the United States. This became the Harvard Six Cities study, a landmark piece of public health research that helped to prove the link between fine-particulate air pollution and higher death rates when it was published in 1993. Early life Ben Greeley Ferris, a distant relative of polar explorer Adolphus Greely, was born in Watertown, Massachusetts in 1919 to parents General Benjamin Greeley Ferris, Sr. and ...

Watertown, Massachusetts
Watertown is a city in Middlesex County, Massachusetts, United States, part of Greater Boston. The population was 35,329 in the 2020 United States census, 2020 census. Its neighborhoods include Bemis, Coolidge Square, East Watertown, Watertown Square, and the West End. Watertown was one of the first Massachusetts Bay Colony settlements organized by Puritans, Puritan settlers in 1630. The city is home to the Perkins School for the Blind, the Armenian Library and Museum of America, and the historic Watertown Arsenal, which produced military armaments from 1816 through World War II. History Archeological evidence suggests that Watertown was inhabited for thousands of years before European colonization of the Americas, colonization. In the 1600s, two groups of Massachusett, the Pequossette and the Nonantum, had settlements on the banks of the river later called the Charles, and a contemporary source lists "Pigsgusset" as the native name of "Water towne." The Pequossette built a fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Doll
Sir William Richard Shaboe Doll (28 October 1912 – 24 July 2005) was a British physician who became an epidemiologist in the mid-20th century and made important contributions to that discipline. He was a pioneer in research linking smoking to health problems. With Ernst Wynder, Bradford Hill and Evarts Graham, he was credited with being the first to prove that smoking increased the risk of :lung cancer and :heart disease. (German studies had suggested a link as early as the 1920s but were forgotten or ignored until the 1990s.) He also carried out pioneering work on the relationship between radiation and leukaemia as well as that between asbestos and lung cancer, and alcohol and breast cancer. He however, initially for many years, stood in opposition to research done by Alice Stewart which connected radiation exposure of pregnant mothers to development of leukaemia in their children due to her 'questionable' analysis. On 28 June 2012, he was the subject of an episode of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Smoking
Passive smoking is the inhalation of tobacco smoke, called passive smoke, secondhand smoke (SHS) or environmental tobacco smoke (ETS), by individuals other than the active Tobacco smoking, smoker. It occurs when tobacco smoke diffuses into the surrounding atmosphere as an aerosol pollutant, which leads to its inhalation by nearby bystanders within the same environment. Exposure to secondhand tobacco smoke causes many of the same health effects of tobacco, health effects caused by active smoking, although at a lower prevalence due to the reduced concentration of smoke that enters the airway. According to a World Health Organization (WHO) report published in 2023, more than 1.3 million deaths are attributed to passive smoking worldwide every year. The health risks of secondhand smoke are a matter of scientific consensus, and have been a major motivation for smoking bans in workplaces and indoor venues, including restaurants, bar (establishment), bars and night clubs, as well as so ...

Douglas Dockery
Douglas William Dockery is an American epidemiologist and the John L. Loeb and Frances Lehman Loeb Professor of Environmental Epidemiology, Emeritus, at the Harvard School of Public Health (HSPH). He is known for his contributions to understanding the health effects of air pollution. Education Dockery received his B.S. in physics from the University of Maryland and his M.S. in meteorology from the Massachusetts Institute of Technology in 1972, where he studied under biometeorologist Helmut Landsberg. He further pursued meteorology at the Massachusetts Institute of Technology (MIT) under the guidance of Edward Lorenz, completing a master's thesis on the predictability of atmospheric models in 1972. Dockery continued his education at the Harvard School of Public Health, obtaining both a Master of Science (M.S.) and a Doctor of Science (Sc.D.) in Environmental Science. His doctoral research, supervised by John Spengler, focused on personal exposures to fine particulate matter. Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are '' linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However, in g ...

Richard Peto
Sir Richard Peto (born 14 May 1943) is an English statistician and epidemiologist who is Professor of Medical Statistics and Epidemiology at the University of Oxford, England. Education He attended Taunton's School in Southampton and subsequently studied the Natural Sciences Tripos at Trinity College, Cambridge followed by a Master of Science degree in Statistics at Imperial College London.

Automobile Exhaust
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an ''exhaust plume''. It is a major component of motor vehicle emissions (and from stationary internal combustion engines), which can also include crankcase blow-by and evaporation of unused gasoline. Air pollution from burning fossil fuels is estimated to kill over 5 million people each year. Motor vehicle emissions are a common source of air pollution and are a major ingredient in the creation of smog in some large cities. Composition The largest part of most combustion gas is nitrogen (N2), water vapor (H2O) (except with pure-carbon fuels), and carbon dioxide (CO2) (except for fuels without carbon); these are not toxic or noxiou ...

Sumner Tunnel
The Sumner Tunnel is a road tunnel in Boston, Massachusetts, United States. It carries traffic under Boston Harbor in one direction, from Logan International Airport and Route 1A in East Boston. The tunnel originally deposited traffic at the west side of the North End, but with the completion of the Big Dig, it was modified to have two exits. One exit connects to I-93 northbound and downtown Boston (Government Center) near Haymarket Station. The other exit connects to Storrow Drive and Nashua St., connecting Cambridge via Route 28. Traffic headed for I-93 southbound and the Massachusetts Turnpike (I-90) westbound is normally routed to the Ted Williams Tunnel. It is managed by the Massachusetts Department of Transportation. History The Sumner Tunnel was opened on June 30, 1934. It carried traffic in both directions until the opening of the parallel Callahan Tunnel in 1961. The Sumner Tunnel is named for William H.
