If measurements are sufficiently accurate, then all food can be sampled for their metal content. If not, then no accurate measurements can exist of metals also flushed out.

A second method is periodic tissue sampling. For example, if a metal concentration increases, then hair samples can measure that concentration AND provide a timeline for those concentrations.

But again, measurements must have sufficient resolution so that what exists in food is also quantified.

A friend negotiates power plant sales. Some lands adjacent to power plants cannot be developed due to routine mercury output by fossil fuel (electric) plants. And yet these lands are safe for golf or other visitation. One who cannot detoxify heavy metals could be adversely harmed by playing golf on that course. A body that cannot flush out heavy metals would be at great risk at many public locales - speculation based in subjective reasoning.
