Why hasn't anybody connected it?

One reason that Louisiana just amuses me:

Yesterday the entire downtown area smelled so strongly of natural gas that I could smell it in my 7th floor office and was dizzy and nauseous the entire day from it. According to this news article, they decided it wasn't dangerous and that they couldn't find out where the heck it was coming from:

The problem is that nobody can seem to find the gas leak. DEQ officials combed through the Capitol area this morning with air monitors looking for the leak's orgin. Entergy crews were also on hand tapping their lines but found no signs of a leak. Police then turned to the river. They checked barges for any evidence of a strong odor there but again found nothing.

So, today is another day at work. Smell isn't as strong but people who live on the other side of the Mississippi say that it's over there now (my office overlooks the river on the other side of them). So then this came out in the newsbreak:

That smell has now been traced to a leaking barge. Authorities tell 9 News that the chemical is called Sodium Hydrosulfide solution. It is toxic if it is inhaled, ingested or touches the skin but authorities say the children are in no danger.

I'm no science genius but um, couldn't these two be related? And if the smell is so dadgum strong, doesn't that mean that it's in the air and could harm us?

And they wonder why they call Baton Rouge - New Orleans along the Mississippi "Cancer Alley".
