对1995 ~ 1996年冬季在加拿大销售的矿泉水、泉水和其他瓶装饮用沃茨水中的氯酸盐、溴化物、溴酸盐、Cr（VI）、Li、B、Al、Mn、Cu、Zn、Sr、Ba、Be、V、Cr、Co、Ni、As、Se、Mo、Ag、Cd、Sb、Tl、Pb、Na、K、Ca和Mg进行了检测。氯酸盐和溴离子色谱法（IC）电导检测，铬（VI）的IC比色检测，溴酸盐溶剂萃取和气相色谱法（GC），微量元素电感耦合等离子体质谱法（ICPMS），和Na，K，Ca和Mg火焰原子吸收光谱法（FAA）。分析的199个样本中的大多数化学品完全符合国家和国际饮用水准则。B（22个样品）、Al（9个）、Cr（1个）、Mn（5个）、Ni（1个）、As（10个）、Se（24个）和Pb（1个）超过世界卫生组织和/或加拿大饮用水指南。报告溴酸盐水平仅供参考，并将其视为样本中的最大浓度。在三种蒸馏水产品中，发现了意外高浓度的Cu（88-147 μ l（-1））和Ni（16-35 μ l（-1）），并且对来自两种品牌的蒸馏和非蒸馏沃茨的比较表明，可能的原因是蒸馏过程中的污染。一个样本中的锂浓度处于治疗剂量，可能对服用锂药物的个体造成过量风险。
Mineral, spring and other bottled drinking waters sold in Canada in the winter of 1995-96 were surveyed for chlorate, bromide, bromate, Cr(VI), Li, B, Al, Mn, Cu, Zn, Sr, Ba, Be, V, Cr, Co, Ni, As, Se, Mo, Ag, Cd, Sb, Tl, Pb, Na, K, Ca and Mg. Chlorate and bromide were determined by ion chromatography (IC) with conductivity detection, Cr( VI) by IC with colorimetric detection, bromate by solvent extraction and gas chromatography (GC), trace elements by inductively coupled plasma mass spectrometry (ICPMS), and Na, K, Ca and Mg by flame atomic absorption spectrometry (FAA). Most chemicals in the 199 samples analysed were well within national and international drinking water guidelines. World Health Organization and/or Canadian drinking water guidelines were exceeded for B (22 samples), Al (9), Cr (1), Mn (5), Ni (1), As (10), Se (24) and Pb (1). Bromate levels are reported for information purposes and are considered as the maximum concentrations in the samples. In three distilled water products, unexpectedly high concentrations of Cu (88-147 mug l(-1)) and Ni (16-35 mug l(-1)) were found, and a comparison of distilled and non-distilled waters from two of the brands suggested the likely cause to be contamination during the distillation process. Li concentration in one sample was at a therapeutic dose and could pose an overdose risk to individuals on Li medication.
