Dr Banauch said it was impossible to predict whether the dust-exposed workers will continue to experience an accelerated decline in lung function, but added that the massive exposure to irritating alkaline dust could possibly increase some workers' future risk of developing emphysema and lung cancer.
"My personal opinion is that when the towers collapsed a lot of building materials were pulverized so there was a lot of cement in the dust, which is very alkaline and which we know that causes burns."
Dr Paul Cullinan, an occupational and environmental respiratory disease specialist at Imperial College, commended the researchers on their study. He said the he was surprised at the extent of the respiratory problems identified by the researchers.
