Science & Mathematics - 8 January 2007

The only reason why I'm asking this question is because of the news items on Comcast. In New York today, they had that horrible odor from natural gas all over the city. They also had that same smell this past summer. In Austin, Texas they had an odor issue and there were 60 birds found dead on one street. My question is for serious chem students or instructors only.

Can the explusion of nerve gas be masked by other odors and if so, does the injection of another chemical render the affects of nerve gas to null?

Had I not read this article, then the thought wouldn't have crossed my mind. However, since I did read them and I'm intelligent in some subjects, this is not my forte' although it has always been an area of interest for me. Also, I'm not a panic person, I just like gathering information for my own self. It is important to me, so I would appreciate a serious answer and an honest one. I don't look for problems, but I'm an analytical person. Thanks for your time.
