> if new additives are causing more hazardous 
> diesel emissions to bees...

I think that the unintentional comedy has gone on long enough.

There has been no mention of any "new fuel additives" as a result 
of the shift to the new "Ultra-low sulfur" diesel fuel.  All that 
has been done is that the sulfur content of the fuel has been reduced.  
The basic idea here was to make diesel emissions LESS hazardous.

The impact was measurable and immediate. NOx and SOx emissions 
(oxides of nitrogen and sulfur) went way down in areas away 
from the impact of power plant smokestacks.  Particulates 
(soot) also went way down.  

The reduction in sulfur does imply that prudent truckers will
use new diesel engine oils of the type "CJ-4", but the change
in the suggested engine oil is the only change that results from 
the change in fuel.  (Apparently, the high sulfur content provided 
a lubrication advantage.)

Bob's questions have already been answered by the European experience.
European trucks have been following "low-sulfur standards" for years,
and amazingly enough, European bees have not been dropping dead or
suffering from unusual post-movement symptoms.

If anyone is interested, the details are documented in staggeringly
boring articles like this one:
