WTC Left Sedimentary Fingerprint

Quixotic1 writes "The NSF announced scientists had found a "distinct fingerprint on the sedimentary record in New York Harbor" due to the destruction of the World Trade Center. The findings were extrapolated from the presence of high concentrations of several elements that make up gypsum, a material used in drywall, and silica, likely from fiberglass."

I wonder about other studies...

[Simon Field]

I wonder if anyone did similar studies after such events as Chernoble, the oil fires in Iraq, or after some volcanic eruptions.

Interesting about the radioactive iodine though. This may be an easier way to study urban water pollution patterns than looking for antibiotics or hormones in the water.

Dust to Dust

[Madcapjack]

I thought that this was an interesting article, and I think that it doesn't deserve the (mostly) silly comments so far posted. But the article just doesn't offer to much to talk about.

I think that the situation was fortuitious for scientists who want to study how particles spread, especially in the New York region. It is an interesting study for that reason. But it isn't surprising that there is such a signature showing in the bay.

Alarmist myth

[Farang]

One of the goofy things reported shortly after the collapse: that the WTC contained huge quantities of asbestos. The deadly dust would cause thousands of cases of cancer in years to come, according to this urban myth. No mention of asbestos in the article, CMIIAW. Anyone else hear this asbestos rumor? I think I need to be a little more selective in my news sources....
