Figure 2

Examples of coordinated changes in elements from the 9/11 WTC dust and its leachate tested at different sites. Left Column: ‘Codissolved’ in the leachate with a similar pattern per collecting site we have: uranium, manganese and magnesium; barium and strontium; rubidium and potassium. Right Column: A similar dust pattern was observed by uranium, beryllium, manganese, titanium, magnesium and aluminium; by strontium, barium, lanthanum, cerium and antimony; by iron and arsenic (flat regions, sites that were not measured). Two values at the right of each graphic (08 and 09) correspond to the girder coatings while samples 20 and 36 at their left side correspond to the indoors. Symbols: mg/L—milligrams per liter; μg/L—micrograms per liter; ppm—parts per million.
