“…The second component represented a variation of approximately 14.014% with its own value of only 1.542. Factor 2 had a strong positive charge for Co (0.704) and Zn (0.882); both elements have an anthropogenic origin and the main sources are the mining and industrial sites from the southwestern part of Romania [ 67 ]. The third component displayed a smaller variation than the first two components, namely 11.153%, with an eigenvalue of 1.227 dominated by the positive charge of Cr (0.273), Cu (0.239) and Cd (0.642) through copper and charcoal mining and a strongly negative charge in the case of Pb (−0.830) through the former uranium mines.…”

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.

“…However, their growth process makes them susceptible to the accumulation of heavy metals from the environment, which can have detrimental effects on human health, such as osteoporosis, rickets, and dwarfism [1][2][3] . Various conventional analytical techniques, including atomic absorption spectrometry (AAS) [4][5][6] , inductively coupled plasma-optical emission spectrometry (ICP-OES) [7,8] , and ICP-MASS spectrometry [9] , are commonly employed for the detection and quantification of heavy metal ions. Although these analytical methods possess remarkable stability, precision, and low detection limits, their lack of universalization and portability is attributed to the bulky and costly instruments employed.…”

“…Even if the orogenic heavy metal occurrence is expected in terrestrial environmental matrices, anthropic influence in disrupting the natural equilibrium is very high [ 4 ]. Mining activities, industry and agriculture development, and city expansion in the study area released impressive amounts of heavy metals accumulating in soils, aquatic ecosystems, forestry, and agricultural lands [ 5 , 6 , 7 , 8 ]. Above all, the impact of contamination on human health represents a key driving factor for food security investigation using various proxy as foodstuffs, spices, or wines [ 9 , 10 , 11 ].…”

The climate warming trend challenges the chemical risk associated with wine production worldwide. The present study investigated the possible difference between chemical wine profile during the drought year 2012 compared to the post-drought year 2013. Toxic metals (Cd and Pb), microelements (Mn, Ni, Zn, Al, Ba, and Cu), macroelements (Na, Mg, K, Ca, and P), isotopic ratios (87Sr/86Sr and 206Pb/207Pb), stable isotopes (δ18O, δ13C, (D/H)I, and (D/H)II), and climatic data were analyzed. The multivariate technique, correlation analysis, factor analysis, partial least squares–discriminant analysis, and hierarchical cluster analysis were used for data interpretation. The maximum temperature had a maximum difference when comparing data year apart. Indeed, extreme droughts were noted in only the spring and early summer of 2012 and in 2013, which increased the mean value of ground frost days. The microelements, macroelements, and Pb presented extreme effects in 2012, emphasizing more variability in terms of the type of wine. Extremely high Cd values were found in the wine samples analyzed, at up to 10.1 µg/L. The relationship between precipitation and δ18O from wine was complex, indicating grape formation under the systematic influence of the current year precipitation, and differences between years were noted. δ13C had disentangled values, with no differentiation between years, and when coupled with the deuterium–hydrogen ratio, it could sustain the hypothesis of possible adulteration. In the current analysis, the 87Sr/86Sr showed higher values than in other Romanian studies. The temperature had a strong positive correlation with Pb, while the ground frost day frequency correlated with both Pb and Cd toxic elements in the wine. Other significant relationships were disclosed between the chemical properties of wine and climate data. The multivariate statistical analysis indicated that heat stress had significant importance in the chemical profile of the wine, and the ground frost exceeded the influence of water stress, especially in Transylvania.
