Air Quality
Back Bay Station has suffered for some time from poor air quality, and people with lung conditions have been advised to avoid the station. A study conducted in 2006 and again in 2008 showed that "The air was many, many times below air-quality standards," due to trapped diesel exhaust and soot. Much of the commuter rail platforms at Back Bay are covered and enclosed, and so fumes cannot escape quickly to the outside air. An earlier study showed elevated levels of carbon monoxide, formaldehyde, particulates, and oxides of nitrogen, though it noted that there is no regulated standard to meet for indoor air quality in public spaces. Though simple changes were made regarding scheduling, and checking to make sure train engines were running properly, an MBTA spokesman stated that the MBTA did not have the financial resources to upgrade the ventilation system.
In 2010, the MBTA announced that it had secured $3.0 million to improve the ventilation in the lobby as a result of federal stimulus money. While MBTA spokesman Joe Pesaturo said there was no health threat, a scientist at the Clean Air Task Force, a Boston-based nonprofit pollution research group stated, "Honestly, down on the platform it was some of the worst air quality I’ve measured." Additionally passengers and clerks working in the station have complained. The MBTA says it will complete an improved ventilation system by 2012.

Famous quotes containing the words air and/or quality:
“Then, that no region of the universe
Should remain void of life, the floor of heaven
Was peopled with the stars and godlike forms,
The seas became the abode of glittering fish.
Earth took the beasts and mobile air the birds.
A holier animal was wanting.”
—Ovid (Publius Ovidius Naso)
“The past is interesting not only for the beauty which the artists for whom it was the present were able to extract from it, but also as past, for its historical value. The same goes for the present. The pleasure which we derive from the representation of the present is due not only to the beauty in which it may be clothed, but also from its essential quality of being present.”
—Charles Baudelaire (1821–1867)
