Lucy+survey...ground+zero

This article is informing us that recent rescue and recovery workers at ground zero have devloped "asthma at a rate that is 12 times what would have expected for adults." With time and studies, the possibility that the dust from the 9/11 event was a factor for these workers getting asthma. "when the dust cloud and smoke from the fires were thickest and respirator masks were least avaliable" the risk was at its hightst for developing asthms. This disease was increasing 3 percet every ten days on the site, ground zero. With studies, they concluded that protective breathing equiment like respirator masks did have a positive effect on the workers who wore them. Now that the workers are back at work pot 9/11, the city has made it so a proper respiratory equiment has to be used while working on site. Firefighters especially have to wear these. It is a standard that these workds have to folow. Not jut any protective mask would sacrfice. "the study showed that asthma rates increased even amoung workers who were wearing masks. Just wearing a mask doesnt gaurantee safety." "still the study is one of the largest and most comprehensive reports linging ground zero dust to respiratory disease."
