Now the University of Pennsylvania is opining that the death by cancer of nearly 33% of the dogs involved in search and rescue is "merely coincidental".
Liz at Blondesense has written about the environmental impact on New Yorkers from the collapse of the towers.
It doesn't take a rocket scientist (or a veternarian) to see that something is terribly wrong.
Fourteen search and rescue dogs have died since their exposure to toxic rubble from the Sept. 11 terrorist attack - including eight from cancer, according to a study by the University of Pennsylvania School of Veterinary Medicine. But researchers believe there is no connection between the deaths and the chemicals they were exposed to.
Despite the study's findings, some of the owners whose dogs have died still blame the toxic brew the dogs immersed themselves in during the hunt for survivors and remains.
