In assessing the ecotoxicity of metals
in the various environmental compartments (aquatic, terrestrial and
sediment), it is assumed that toxicity is not controlled by the total
concentration of a metal, but by the bioavailable form. For metals, this
bioavailable form is generally accepted to be the free metal-ion in
solution. In the absence of speciation data and as a conservative
approximation, it can also be assumed that the total soluble lead pool
is bioavailable. All reliable data on ecotoxicity and environmental fate
and behaviour of lead and lead substances were therefore selected based
on soluble Pb salts or measured (dissolved) Pb concentration.
The reliable data selected for the
environmental fate and behaviour of lead are all based on either
monitoring data of prevailing lead concentrations in water, soil,
sediment, suspended matter and organisms or on experimental resultswithlead
(di)nitrate and lead chloride. All reliable data are expressed based on
elemental Pb concentrations and grouped together in a read-across
approach and will be used for all lead substances because upon
dissolution of lead substances, the Pb-ion is the controlling adsorption
