Listen, everyone who could smell the smoke and dust at anytime anywhere in this city was exposed to toxins. Believe it. Just what the ingredients were (or still ARE since it all could still be lingering around) that may cause real health problems to manifest over the coming years will be speculated on massively. That so many conflicting official opinions from a multitude of various organizations keeps cycling through the official voices we hear is a sure red flag and really indicates that the governmental agencies do not really want to talk much about it. One of the very first reports about contaminants in the dust simply said incomplete information was being released because to accurately point out the amount and wide range of toxins would necessitate a clean up of a scope and scale that simply was beyond current resources to effect. My brother worked on the pile for several months as a volunteer and said it was impossible to get the stench or actual dust off work clothes, that a high proportion of workers didn't even wear breathing filters of any kind. It is in you. To what degree and what the consequences will be, if any, won't be known for a long time. I don't say this to be an alarmist, just to be realistic. I still haven't been able to finish emotionally processing the reality that that dust contained the atomized remains of fellow citizens. That I, that we all, have become the final resting place for many caught in the atrocity.
