The death toll among those sickened by the toxic dust and ash of Ground Zero will within as little as five years exceed the number of people killed on the day of the 9/11 attacks, experts say.
As those who lost loved ones at the World Trade Center, at the Pentagon and on Flight 93 gather for Sunday’s 15th anniversary of the terror attacks that killed almost 3,000 people, a post-9/11 health crisis is growing.
At least 1,000 people – and probably many more – have died often lingering, painful deaths resulting from illnesses related to their exposure to debris that spread from the wreckage of the World Trade Center towers in downtown Manhattan. More than 37,000 are officially recognised as sick.
Calls are growing for a new monument to be added to the World Trade Center site, to pay tribute to those who have died or become sick since 9/11 because of toxic exposure.
