Here is the MSDS sheet for Magnesium chloride.

and for Calcium magnesium acetate

Looks like they use liquid magnesium chloride and/or calcium magnesium
acetate. If it's the former, you should rinse your bike because it's
corrosive.

The following is taken from a ODOT doc I found here:

http://www.oregon.gov/ODOT/TD/TP_RES/docs/Reports/DeicerAppOpenPavements.pdf

ODOT may use one of the following types of winter anti-icing/deicing

liquids:

1. Magnesium chloride:

. Contains a corrosion inhibitor to reduce impacts to vehicles.

. Works well at very cold temperatures.

. Fairly inexpensive.

2. Calcium magnesium acetate:

. Acetic acid (strong vinegar) mixed with lime.

. Less corrosive than tap water.

. Does not work well at very cold temperatures.

. Moderately expensive.

Subject: [OBRA Chat] De-Icer Fluid

Hey ORBRA Land,

Does anyone in OBRA land know much about the De-icer fluid being used by the
city. I have been riding the west hills the past few days an noticed they
are spraying the fluid on the road and I am now catching the scent of this
stuff and, at some places it is pretty strong. Wondering if I should avoid
the roads that are being sprayed. I am sure it is not dangerous, but still,
I wonder what it is doing to our lungs. Any feedback would be great Thanks

James

I asked county road crews last year and they told me magnesium chloride with rust inhibitors.  I think Dan's research is probably more correct...ie, usually MgCl but sometimes magesium acetate.
 
As far as your lungs, I'd be far more concerned about the exhaust of passing vehicles.
