FINANCING FRESH AIR: INCENTIVIZING BOILER CONVERSIONS IN NEW YORK CITY ASSEMBLYMEMBER DAN QUART, JANUARY 2014 A BRIEF HISTORY OF POOR AIR QUALITY IN NEW YORK CITY In the 1950’s and 1960’s, New York City’s poor air quality was at crisis levels. Isolated smog events were widely reported as emergencies, killing hundreds over the course of a few separate weeks.1 In 1953, New York suffered from what is still the nation’s worst air pollution disaster: 11 days of smog during November resulted in the death of somewhere between 175 and 260 people, due to a temperature inversion.2, 3 Later, in the 1960’s, temperature inversions were responsible for two more pollution events, leading to the death of 200 people in 1963 and 168 in 1966.4 These individual events are attention-grabbing, but air quality before environmental regulation was also alarming. For example, sulfur dioxide, one of the earliest pollutants to be tracked, is now monitored at an order of magnitude higher than it was in the mid-twentieth century. A study of the 1953 smog crisis lists the normal level of sulfur dioxide at the end of the crisis as .09 ppm (parts per million).5 In 2013, sulfur dioxide levels were reported to have dropped from 5.6 ppb (parts per billion) to 1.7 ppb, or .0017ppm.6 We now know that the health effects of sulfur dioxide exposure, including bronchoconstriction and increased asthma symptoms, can be experienced at much lower levels than previously believed. Currently, the EPA has set a long-term standard for sulfur dioxide at .03 ppm, 300% lower than typical sulfur dioxide levels in the 1950’s.7 The lack of air quality monitoring throughout much of the 20th century ensures that we’ll never know exactly what the effects were of the poor air quality that plagued New York throughout the 20th century.
