这项研究是作者进行的一系列调查中的第三项,当然是关于前铀的最全面的研究,铜,和来自罗马尼亚特定地理区域的木炭矿。在这方面,目前的科学入侵集中在两个包含前铀矿石开采地点的地区,Ciudanovita和Lisava,以及摩尔多瓦努阿的铜矿和阿尼娜的木炭矿,巴纳特地区,罗马尼亚。它强调,第一次,重金属浓度与水的物理化学指标值相关(即,EC,DO,pH值,电阻率,盐度,和ORP),通过使用多变量分析,塑造一个基于空间分布和来自Banat水文盆地的有毒污染物变异性的区域模型,罗马尼亚,作为前铀的结果,铜,还有木炭矿.在这方面,包括Al在内的11种金属,Cr,Mn,Fe,Ni,Co,Cu,Zn,Sr,Cd,和不同水样中的Pb(嗯,spring,河,和湖),从三个矿区收集(铀,铜,和煤矿)进行了调查。使用EDI评估了7种重金属的非致癌和致癌健康风险,DIM,和THQ。获得的THQ值在成人癌症风险的可接受范围内,但是关于孩子,18个样本中有8个被证明是有毒的.然而,儿童Cd(0.265成人/0.996儿童)和Pb(0.025成人/0.095儿童)的HRI和THQ平均值比成人高3-4倍。这是一个令人担忧的问题,因为它们在井水中的流行使Banat地区的儿童和居民面临各种癌症的风险。
This study is the third in a series of investigations conducted by the authors, and certainly the most comprehensive research regarding the former uranium, copper, and charcoal mines from a particular geographical area of Romania. In this respect, the present scientific incursion focused on two areas containing former extraction uranium ore sites, Ciudanovita and Lisava, as
well as copper ore from Moldova Noua and charcoal mines from Anina, Banat Region, Romania. It highlighted that, for the first time, the heavy metal concentration was correlated with the values of physicochemical indicators of water (i.e., EC, DO, pH, resistivity, salinity, and ORP), by using multivariate analysis, to shape a regional based model on spatial distributions and the variability of toxic contaminants from the hydrographic basin of Banat, Romania, as a consequence of former uranium, copper, and charcoal mines. In this regard, 11 metals including Al, Cr, Mn, Fe, Ni, Co, Cu, Zn, Sr, Cd, and Pb from different water samples (
well, spring, river, and lake), collected from three mining areas (uranium, copper, and coal mines) were investigated. Non-carcinogenic and carcinogenic health risks of seven heavy metals were assessed using the EDI, DIM, and THQ. The obtained THQ values were within the acceptable limits for cancer risks for adults, but as regards children, eight samples out of 18 proved toxic. However, the HRI and THQ average values for Cd (0.265 adults/0.996 children) and Pb (0.025 adults/0.095 children) for children were 3-4 times higher than those for adults. This is a source of concern as their prevalence in
well water exposes children and residents in the Banat Region to the risk of various types of cancers.
