DCHAS-L Discussion List Archive

Here is an interesting one from TCI (2013).  They seem to know less now about this chemical than Eastman did in 2005.  Hmmmm...

Section II; 

Acute toxicity data, if available, are listed below. Additional toxicity data may be available on request.

Oral LD-50:(rat)   825 mg/kg

Dermal LD-50: ( rat)  >2,000 mg/mg

Skin Irritation (rabbit)  strong

Skin Sensitization: (guinea pig)  none

 

So it is toxic (500-5000 mg/kg), and an irritant. This must be Eastman's own since I don't see it elsewhere.  And I think I'll write to Eastman for the "additional toxicity data."   I've looked and looked for chronic anything on it.

According to FEMA and West Virginia Div of Homeland Security and Emergency Management, the "crude" chemical was spilled.  They have a link to the following MSDS:  http://mediad.publicbroadcasting.net/p/wvpn/files/201401/MSDS-MCHM_I140109214955.pdf#!

FYI, the Elk River where the chemical spilled into, is a tributary that eventually leads into the Ohio River, then into the Mississippi.  I had wondered if it was coming my way down the Potomac River.   JL
