Exposures Short Term vs. Long Term "3
Some substances have short-term irritating effects for some peopie (e.g. particuiate matter)
Some substances have iong -term effects, generaliy when exposures are for relatively long periods of time at higher levels of exposure (e.g. asbestos)
The numerous potential substances of concern have led to some confusion about the potential health effects of various substances. Depending on the substance, the effects will differ. Some substances such as the particulate matter from the dust or the smoke in the air can be irritating but are not expected to have long term effects for most people.
Other substances, such as asbestos, are not expected to have short term effects. If exposures were high over long periods of time, these substances could have long term effects.
Asbestos was one of the substances of greatest concern since it was a known building component in the WTC. However, [REFER to EPA maps], the levels of asbestos in the outdoor air, except for a few transient increases found during the initial weeks, decreased after the first month and, thus, cannot be considered long term exposures.
For other substances, once the fires have been extinguished, release of chemicals such as benzene, dioxins and PCBs and furans will not be a concern. 6
