Greece: Town leaders responsible for keeping odors out of town. Rome: Air pollu3on resulted in civil lawsuits. Rome plagued with thousands of wood ­ burning fires, blackened buildings. c. AD 61. Seneca (statesman; Nero s tutor) As soon as I had goYen out of the heavy air of Rome and from the s3nk of the smoky chimneys thereof, which being s3rred, poured forth whatever pes3len3al vapors and soot they had enclosed in them, I felt an altera3on of my disposi3on. 1 3/28/11 History of Air Pollu.on 1200 ­1329 Sea coal introduced 1228 1285 King Edward I mandates first air pollu3on commission 1306: King Edward I bans the use of coal in lime kilns. Punishment was grievous ransom 1329: Ban lost its effect 13th ­18th centuries Coal burning expansion in lime kilns, forges, glass furnaces, brick furnaces, breweries, homes 1661 John Evelyn …most Londoners breathe nothing but an impure and thick mist, accompanied by a fuliginous and filthy vapour, corrup3ng the lungs. Late 1600s Air pollu3on damaged building exteriors so significantly that many leases required repain3ng three 3mes per year. Industrial Revolu.on and the Steam Engine 1700 ­1840 : Industrial Revolu3on Unprecdented growth in industry Growth in average income and popula3on Transis3on from manual/animal labor to machine ­based manufactoring  increase in use of refined coal 1800 ­1900: 100 ­fold increase in coal combus3on; pollu3on deaths Great Britain 4 ­7 x those worldwide Steam Engine Thomas Savery (1650 ­1715) English engineer 1698: Patented first prac3cal steam engine. It replaced horses for pumping water out of coal mines. Did not work well under high pressure. Thomas Newcomen (1663 ­1729) English engineer 1712: Overcame some of problems of Savery s engine. Pumped water out of mines and powered waterwheels. Captured 1% of maximum energy. 2 3/28/11 Steam Engine James WaY (1736 ­1819) Scofsh engineer and inventor 1763: Given a Newcomen engine to repair. 1769: Patented separate chamber for condensing steam Developed engines in which steam supplied to both sides of piston and in which mo3ons were circular versus up and down WaY s engines s3ll only 5% efficient. Pre  ­1900 Regula.on in the U.K. 1843: CommiYee inves3gates pollu3on from furnaces and boilers 1843: 1845: Bills brought before Parliament to limit pollu3on defeated 1845: Railway Clauses Act: Engines must consume own smoke 1846: Public health bill passed requiring smoke reduc3ons from furnaces/boilers. Clause removed following industry pressure 1851: Emission clause in London sewer bill; enforced by cita3on 1853: Smoke Nuisance Abatement Act. Enforced aher many years 1863: Alkali Act: reduced HCl emission during soap produc3on 1858: 1866: Sanitary Acts contained air pollu3on legisla3on 1875: 1891: Public Health Acts 3 3/28/11 Pre ­ 1900 Regula.on in the U.S. 1869: PiYsburgh ordinance outlawing burning of soh coal in locomo3ves within city limits. Not enforced. 1881: Cincinna3 law required smoke reduc3ons and appointment of smoke inspector. Not enforced, but three main causes of death in Cincinna3 in 1886 were lung ­related: tuberculosis, pneumonia, bronchi3s. 1881: Chicago smoke ­reduc3on law. Supported by judiciary but not enforced. 1893: St. Louis city council outlawed dense black or thick gray smoke and appointed inspector. Ordinance overturned by Missouri Supreme Court in 1897 as wholly unreasonable. ~1900 – What happened? 4 3/28/11 Los Angeles, California (December 3, 1909) Library of Congress Prints and Photographs Division, Washington, D.
