Coal plants produce a *lot* of heavy metal.  Mercury in particular:
"Coal plants are responsible for more than half of the U.S. human-caused 
emissions of mercury, a toxic heavy metal that causes brain damage and heart 
problems. Just 1/70th of a teaspoon of mercury deposited on a 25-acre lake 
can make the fish unsafe to eat. A typical uncontrolled coal plants emits 
approximately 170 pounds of mercury each year. Activated carbon injection 
technology can reduce mercury emissions by up to 90 percent when combined 
with baghouses. ACI technology is currently found on just 8 percent of the 
U.S. coal fleet."

I don't think you'll find heavy metals in coal fire plants emmissions.
It a a fossil fuel, mostly carbon, and carbon is not a heavy metal.
These heavy metal thngs are like lead, chromium, mercury, copper, etc.
But I agree all that deet, soap, sunscreen, lip blam, etc. will contaminate 
the high apline lakes.

Ounces of Deet carried/used from Campo to Manning Park:  zero.  I did carry
two ounces of the eucalyptus-lemon spray; used one ounce; in the future
will carry no bug spray.   Gloves, headnet, long pants (with the zip-offs),
and gloves works for me.

Thinking about Ernie’s reminder in a recent post to ”Leave nothing but shoe
prints”, one time I observed lake water where a hiker just emerged from a
bath and detected what appeared to be a newly formed chemical sheen on the
water.  A chemical concoction of deet / sun screen / Gold Bond /
eucalyptus-lemon / permethrin?  Given that many alpine lakes, including the
ones in the Sierra, have some degree of heavy metal contamination from
global emissions from coal fired plants, I wonder about the long term
hiker/societal impacts from chemicals & heavy metals on those lakes:  more
than “shoe prints?”
