Expected risk ER versus risk quotients RQ of 1977 mono-constituent organic REACH chemicals. Light gray symbols: RQ calculated as in REACH (from untransformed concentration data); dark gray symbols: RQ calculated alternatively (from z-transformed concentration data), with σPEC of all chemicals set to 0.3; black symbols: RQ calculated alternatively (from z-transformed concentration data), with all σPEC set to 0
