World Trade Center Dust

Dust from South Tower destruction rose 1,000+ feet

Within one minute of the North Tower's collapse, an immense cloud of thick dust engulfed most of the southern end of Manhattan.

North Tower dust moved east and then to the south

Dust samples taken from Cortlandt, Market, Cherry Streets Cortlandt St Dust Travel

The dust samples were fluffy in composition and light pink to light gray in color Made mostly of destroyed building materials

Glass fibers, cellulose, and cement made up the largest percentage of sample composition Towers built from 1968 to 1972 Asbestos was found to be 3% at Market Street

Concentrations of PAHs found in all three samples

Indoor deposits Not properly cleaned Long-term exposure Only time will tell
