Just curious how do modern humans compare.
I think most people have this notion that sewage treatment removes everything.
I know the local creek that the local water treatment plant empties out into, and the creek smells like sewage. The water intake is maybe km away down river. Aside from obvious chemicals like paint that people might flush. All kinds of medical/drug chemicals they're on are also peed out as well. And those can be active in tiny amounts.

For reference, a normal level of lead in a gram of hair is around 4 micrograms or less. His hair also had 13 times the normal level of arsenic, and four times the normal level of mercury.

It's only fairly recently that we realized how dangerous these metals are and started removing them from things like plumbing (that word comes from french/latin for lead), fuels, paints, even eating-wares. I think north america was using leaded gasoline up until the end of the 70s or so.
