Abstract

文部省科学研究費特定研究(1)「環境汚染の検知と制御」のサブグループである「環境分析における標準物質と分析値の精度に関する研究」班は20名の班員によって構成されていて,試料処理法,微量分析法の実施検討並びに標準対照試料の作成などの基礎研究と併行して,共通試料を選び,班員に配布し,指定された成分についての分析を実施し,そのデータを持ち寄り,いわゆるクロスチェックを行うとともに,誤差範囲の検討や分析法の優劣を討議している.本稿では(1)渡良瀬川河川水(1975.11.14採取)中の銅,亜鉛,鉛,(2)調製水溶液試料についての銅,亜鉛,鉛,カドミウム,クロム,鉄に関しての結果について報告する.

During the last two years 19751976 a research group was organized to evaluate jointly the precision of trace analysis values for environmental samples. The twenty-membered group (chairman Prof. T. Kiba), supported by a Grant-in-aid for Scientific Research from the Ministry of Education (No. 011910), cooperated in the interlaboratory comparison tests of two reference standard materials, i.e. a natural water sample and a composite heavy metal salts solution. The natural water sample was collected at Watarase River on November 11, 1975. The river water and the salts solution were distributed among the members and analyzed, respectively, for Cu, Zn, and Pb and for Cu, Zn, Cd, Pb, Cr, and Fe. Results are listed in Tables 1 and 3. In these trials all members were free of a specified pre-treatment and of a defined measurement technique, and therefore the results obtained seem to give the average precision of the analyses carried out arbitrarily in the university laboratories: the coefficients of variation fall in ten percent order for metals in lower concentration as in river water, and in only a few percent for the same metals in higher concentration and in their stable forms as in the synthesized sample solution.
