"Contaminated" WTC Dust Claims Another Cancer Victim

Interesting how they don't specify WHAT the contaminants were:

Leon Heyward emerged from the subway just as the second plane struck, piercing the south tower. As others fled, he helped evacuate disabled employees from 42 Broadway, where he worked for the city’s Department of Consumer Affairs, and when the first tower fell, he was caught in the churning plume of contaminated dust and smoke.

Within months he started to feel sick. A father of two who prided himself on being fit, Mr. Heyward found himself overcome with fatigue. He had seizures; his memory slipped. Once, while working undercover as an inspector, he forgot where he was. (snip)

Last October, after developing lymphoma, Mr. Heyward died at age 45 in the Bronx, where he was born and had formed one of the earliest rap groups.
