Re: Columbus Center
Q-67. Is UFP air pollution systematically measured?
A-67. No. Government regulation of UFP remains rare, although it is increasing.
Q-68. Can the single Kenmore monitoring station be used to extrapolate regional UFP estimates?
A-68. No. Being one collection point, and being only for the coarse (PM10) and fine (PM2.5) standards, that station?s data can?t be used for regionally extrapolated ultrafine (PM0.1) estimates. Those existing standards don?t address UFPs, and UFP?s public health risks are different. Harvard School of Public Health Associate Professor Dr. Jonathan Levy says, ?The more that we learn, the more it seems that it [ultrafine diesel particulate matter] is contributing to health effects that are different from the other pollutants that we regulate.? (See ?Breathing Dirty Air?, WFXT, 24 April 2008.)
Q-69. Are UFPs more harmful to health than fine and coarse particles?
A-69. Yes. That is the consensus opinion among experts working with particulate matter. There are too many studies to list here, but these two findings are typical.
Q-70. Is permeability an absolute characteristic?
A-70. No. A given material can be non-permeable for water, yet permeable for UFPs; so buildings can deflect rainfall, while allowing UFP matter to pass through, even when windows and doors are kept shut.
Q-71. What do public health officials know?
A-71. Public health officials know that UFP risks pose the greatest urban public health problem in the developed world, leading to a wide range of illnesses and premature death, and that UFPs are most dangerous within a few blocks of their sources. Many studies focused on specific illnesses, age groups, weather conditions, traffic patterns, etc., while collectively validating the general risks to public health.
Q-72. Why should this project be held responsible for UFP air pollution?
A-72. For people who work or live at or near I-90 Parcels 16-17-18-19, Columbus Center itself increases UFP exposure by capturing UFP air pollution from the tunnels running 6 blocks east and 6 blocks west, concentrating it, and then exhausting it via Columbus Center?s 5 vents.
Q-73. Can Columbus Center?s UFP air pollution be eliminated by fresh air intake filters?
A-73. No. On a community-wide basis, fresh air intake filters offer only a marginal improvement, because (a) most buildings have no such facility; and (b) even in buildings with fresh air systems, most UFP-laden air enters via other routes.
Q-74. What happens at Causeway Street and Spaulding Hospital?
A-74. People who work and live near I-93, such as on Causeway Street and at Spaulding Hospital, suffer greater exposure than people along I-90, because of higher traffic volumes.
