While the presence of a minute amount of a single chemical may (or may not) cause health problems, IMO it's the accumulative effect of dozens, hundreds, of differing chemicals which can cause serious problems over time.

After so many decades of hearing government lies, and seeing government agencies influenced by representatives bought out by large corporations, I just can't believe our agencies anymore.

That's pretty sad, IMO, as the vast majority of individuals in these agencies are honest folks trying to do a good job.

But, the political appointees who run those agencies muffle reality, so long as those realities might harm which ever party is incumbent.

Bottom line: money buys everything.
