I've had a chance to numerically summarize the collection of hazmat headlines from google I've sent to DCHAS-L in 2012. Overall, the profile of these events are very similar to 2011 in most respects.
There was a 17% drop in the number of events reported. Part of this can be attributed to 50 fewer reports of meth lab events, but I also noticed in December 2012 that the number of hazmat headlines google has been reporting started to drop precipitously. I'm not sure why that is - the search terms have remained the same. Perhaps the media are implementing more paywalls that are preventing google from finding local stories?
Anyway, the statistical breakouts are for the 1554 2012 events:

Some notes on these numbers:
1. The chemical categories require the most interpretation, both because the media reports are generally vague, and possibly incorrect, and there are often multiple chemicals involved. One trend that arose in that category was the number of homemade chemical bombs reported to be discovered in U.S. public areas in 2012; these are usually attributed to pranks by local authorities.
2. There was good consistency between the country, sector, type and extent between 2011 and 2012. The biggest difference was a decrease in the number of transportation events reported (36%). This might be related to the moderate winter improving travel conditions?
3. I did remove all of the reports on the follow up on the UCLA event and Harran trial before running the numbers. There was still a 25% increase in the number of lab related events reported. This was the only increase in the number of events in a category I noticed. If you simply want to review those events, you can go to

This is raw feed, which will include the UCLA follow up reports as well.
I want to thank the ongoing help of Dr. Rob Toreki of ilpi.com with the computer aspects of this work. The system he put together for tagging and organizing these reports has been remarkably robust of the nearly 2.5 years it has been in place.
Let me know if you have any questions about this.
