| Abstract: | The Japan Society for Analytical Chemistry has recently issued a river water-certified reference material (CRM) for use in
the ultratrace analysis of elements in fresh water. The river water CRM consists of a set of two (natural and spiked) 500-ml
samples. The natural water is certified for Pb, Cr, As, Cu, Fe, Mn, Zn, B and Al at their sub-μg/l levels, while the spiked
water is intended for use in the regulatory analysis of tap water and fresh water.
