Critical loads and their exceedances for ICP-Waters sites (ICP Waters report 44/1998)
, 1998 The International Co-operative Programme on Assessment and Monitoring of Acidification of Rivers and Lakes (ICP Waters) is designed to assess, on a regional basis, the degree and geographical extent of acidification of surface waters. We report here an assessment of critical loads and their exceedances of sulphur and nitrogen acidity for the 92 ICP ...

Summary of The Nine Year Report from the ICP-Waters Programme (ICP Waters report 46/1998)
, 1998 The International Cooperative Programme on Assessment and Monitoring of Acidification of Rivers and Lakes (ICP-Waters) is designed to assess the degree and geographical extent of acidification of surface waters. During the last ten years international emission reduction measures in Europe and North America have resulted in a decrease in atmospheric ...

Strategy for water analysis using ICP-MS
Fresenius' Journal of Analytical Chemistry, 2000 The developed strategy permits determination in three steps of sixty-seven elements using inductively coupled plasma mass spectrometry (ICP-MS). Sodium, Mg, Si, S, Cl, K, and Ca are determined in a first step; B, Al, P, Cr, Fe, Mn, Ni, Cu, Zn, As, Se, Ag, Cd, Sb, Ba, Hg, and Pb are determined in a second step; and Li, Be, Ti, V, Co, Ga, Ge, Br, Rb, Sr,

Determination of tellurium in lake water by ICP-MS.
BUNSEKI KAGAKU, 1997 ICP-MSによる湖水中のテルルイオンの定量に関する基礎検討を行った.まず無機酸類による負の干渉はインジウムを内標準に用いることにより高精度の補正が可能であった.又,湖水中のテルルイオンはpptオーダーであること,及び共存バリウムによる同重体干渉が生じるため,測定前の濃縮と分離操作が必要であった.その手段として水酸化鉄による共沈分離・濃縮法について検討した結果,pH6～10においてテルルの四価,六価イオン共に定量的に共沈され,逆にバリウムイオンは全く共沈されなかった.しかし,測定時にこの多量の鉄イオンがテルルに対し大きな負の干渉を示すため,この鉄を1-フェニル-3-メチル-4-トリフルオロアセチル-5-ピラゾロン-ブチルエーテルの溶媒抽出系により分離した.琵琶湖水11を上記の操作後 ...
