Arsenic is a ubiquitous element which may be found in surface water, groundwater, and drinking water. In higher concentrations, this element is considered genotoxic and carcinogenic; thus, its level must be strictly controlled. We investigated the concentration of total arsenic and arsenic species: As(III), As(V), MMA, DMA, and AsB in drinking water, surface water, wastewater, and snow collected from the provinces of Wielkopolska, Kujawy-Pomerania, and Lower Silesia (Poland). The total arsenic was analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and arsenic species were analyzed with use of high-performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC/ICP-MS). Obtained results revealed that maximum total arsenic concentration determined in drinking water samples was equal to 1.01 μg L(-1). The highest concentration of total arsenic in surface water, equal to 3778 μg L(-1) was determined in Trująca Stream situated in the area affected by geogenic arsenic contamination. Total arsenic concentration in wastewater samples was comparable to those determined in drinking water samples. However, significantly higher arsenic concentration, equal to 83.1 ± 5.9 μg L(-1), was found in a snow sample collected in Legnica. As(V) was present in all of the investigated samples, and in most of them, it was the sole species observed. However, in snow sample collected in Legnica, more than 97 % of the determined concentration, amounting to 81 ± 11 μg L(-1), was in the form of As(III), the most toxic arsenic species.
砷是一种普遍存在的元素，可在地表水、地下水和饮用水中发现。在较高浓度下，该元素被认为具有基因毒性和致癌性；因此，其含量必须受到严格控制。我们调查了从大波兰省、库亚维-波美拉尼亚省和下西里西亚省（波兰）采集的饮用水、地表水、废水和雪中总砷及砷形态（As(III)、As(V)、一甲基砷、二甲基砷和砷甜菜碱）的浓度。总砷通过电感耦合等离子体质谱法（ICP-MS）进行分析，砷形态则使用高效液相色谱-电感耦合等离子体质谱法（HPLC/ICP-MS）进行分析。所得结果表明，饮用水样品中测定的总砷最大浓度等于1.01μg L⁻¹。地表水总砷最高浓度为3778μg L⁻¹，是在受地质成因砷污染影响地区的特鲁亚察河中测定的。废水样品中的总砷浓度与饮用水样品中测定的浓度相当。然而，在莱格尼察采集的一个雪样中发现砷浓度显著更高，为83.1±5.9μg L⁻¹。所有调查样品中均存在As(V)，并且在大多数样品中，它是观察到的唯一形态。然而，在莱格尼察采集的雪样中，测定浓度的97%以上（达81±11μg L⁻¹）为毒性最大的砷形态As(III)。
