Our aim was to determine boron levels in waters of rich boron mine areas in Turkey. There is a naturally occurring high level of boron in the ground waters of some parts of Turkey. Our study area is Hisarcik village in the Kutahya Province of Turkey which has a large number of boron mines. Boron occurs in combined form, usually borax (Na2B4O7 x 10H2O) and colemanite (Ca2B6O11 x 5H2O). Water samples were collected from many springs in order to determine boron concentrations and the amount of boron that is exposed to 88 samples from the drinking water (tap water), 37 from ground water and 257 from stream or pond water (surface water). Urine samples taken from 42 residents in this area were analyzed for boron and compared with its levels in drinking waters. The inductively coupled plasma/mass spectrometry (ICP/MS) method was used for the analysis of boron concentrations. Water boron contents at differing locations of this area ranged from 2.05 to 29.00 mg B/l. Mean value of boron was 10.20+/-4.08 mg B/l. Total urinary boron excretion was ranged from 0.04 to 50.70 mg B/l and mean value was 8.30+/-10.91 mg B/l. Current information on sources, occurrence, pollution potential and toxicity of environmental boron is discussed.
我们的目的是测定土耳其富硼矿区水体中的硼含量。土耳其部分地区的地下水中天然存在高含量的硼。我们的研究区域是土耳其屈塔希亚省的希萨尔吉克村，那里有大量硼矿。硼以化合态存在，通常为硼砂（Na2B4O7·10H2O）和硬硼钙石（Ca2B6O11·5H2O）。为了测定硼浓度，从多个泉水中采集了水样，其中88份来自饮用水（自来水），37份来自地下水，257份来自溪流或池塘水（地表水）。对该地区42名居民的尿液样本进行了硼分析，并与饮用水中的硼含量进行了比较。采用电感耦合等离子体质谱法（ICP/MS）分析硼浓度。该地区不同地点的水体硼含量在2.05至29.00毫克硼/升之间。硼的平均值为10.20±4.08毫克硼/升。尿硼总排泄量在0.04至50.70毫克硼/升之间，平均值为8.30±10.91毫克硼/升。文中讨论了有关环境硼的来源、存在形式、污染潜力和毒性的现有信息。
