>117mg/kg God forbid the authors spend 60sec to transform the unit into something that is easily visualize-able to the general public. That should be SOP when writing and editing these kinds of press releases. Density of typical soil is around 1250kg/m^3 so 117mg/kg is ~146g/m^3. Density of lead is 1.34g/cm&^3 so ~146g/m^3 is 110cm^3 or roughly the size of a small container of cough syrup or 3-4 decent sized fishing weights per cubic meter of soil. That's a lot of lead but probably readily attainable under certain circumstances.
