Abstract

The experimental procedures for the preparation of a reference material consisting of a sewage sludge and the certification of eight element contents, expressed as mass fractions (cadmium, cobalt, copper, manganese, mercury, nickel, lead and zinc) are reported. Values are given for the element contents (mass fractions) of chromium, selenium, and the aqua regia soluble contents (mass fractions) of cadmium, copper, manganese, nickel, lead, zinc and chromium. Indicative values are presented for matrix constituents and further trace elements. The technical evaluation of the analytical methods used and the statistical approach by which the certification of the eight element contents (mass fractions) and their uncertainties were drawn from the analytical results are also presented.
