A further look at zinc : a response to the industry addendum to the integrated criteria document zinc

Comprises a response to the "Industry addendum" (IA), published in 1995, in which comments are given on the "Integrated criteria document zinc" (ICDZ) published in 1992 by RIVM. The present report is focused on the main points of criticism: the ecotoxicological data (NOEC values) used in deriving maximum tolerable concentrations (MTC values) in surface water and soil, the value of the MTC in surface water and soil, in relation to the background concentration in these compartments, and the estimate of the emission due to atmospheric corrosion of zinc and galvanized steel.
