Messing (von mittelhochdeutsch messinc) ist eine Kupferlegierung mit bis zu 40 % Metalle können in geringeren Anteilen hinzugefügt werden, um den Guss-oder Knetlegierungen bestimmte Eigenschaften zu geben. Aus Messing hergestellte Gegenstände haben eine messing(e)ne (von mittelhochdeutsch messīn, „aus Messing hergestellt, Messing-") Farbe.
Six heavy metals (Hg, Cu, Cd, Cr, Pb, Zn) and 1 metalloid (As) in surface soils of Hong Kong were investigated in 10 land use categories (urban park, greening area, country park, rural area

· Also, Cu, Zn and Pb concentration values found in this study were determined to be higher than the values measured on the northwestern Black Sea Coast of Romania and the northeastern Black Sea Coast of Georgia (Secrieru and Secrieru, 2022: –, 1–185 and – μg g − 1, respectively; Wilson et al., 2022: 30–117, 17–114 and μg g − 1, respectively).
· The mean level of minerals (Zn, Pb, Cu, Mg, Se) in serum samples were compared in both cases and controls by using independent-samples t-test for normal distribution and Mann-Whitney U test as a non-parametric test. All statistical analyses were carried out using SPSS RESULTS: As well as the Zn, Cu, and Se, there was no significant difference between MS patients and healthy individuals
Pb, Zn, Cu and Cd in the dustfall as well as in the suspended particulate samples were analytically determined using Graphite Furnace Atomic Absorption Spectrophotometry (GF-AAS) with a Varian Model, GTA 100. Results and Discussion Heavy Metal Concentrations in Air The average level of particulate matter collected on the lters was mg/cm2 and the range was from mg/cm 2at
The precise replication of metal chloride to oxide ratios, such as the precise ratios of Cu-, Fe-, Pb-, and Zn-chlorides and oxides, may be an essential factor in changing the thermochemical formation patterns of aromatic-Cls. Although CuCl 2 acted as a promoter of aromatic-Cls generation, statistical analyses implied that FeCl 3 also largely influenced the generation of aromatic-Cls under
· The total concentrations of Zn, Pb, Cu and Cd were high in the pyrite cinder; especially zinc, ranging between and % by weight . Comparing the total concentrations with the EDTA extractable fraction only 10–60% of Cd, Cu and Zn, but most of the Pb (60–) was estimated to be geochemically active .
The text then ponders on Caledonian massive sulfide deposits in Scandinavia, Precambrian, strata-bound, massive Cu-Zn-Pb sulfide ores of North America, and geology of the Zambian Copperbelt. Concerns cover types of orebodies, structures of the Zambian Copperbelt, geology of representative deposits, general geological features, and lithostratigraphical relations of the ores.
· Second, we intended to compare the results with previously determined Pb, Cu and Zn isotopic compositions for São Paulo (Gioia et al., 2022, 2022, Souto-Oliveira et al., 2022), London (Dong et al., 2022) and Barcelona (Ochoa and Weiss, 2022), to (i) identify possible city specific differences and (ii) test critically the wider potential for Cu, Zn and Pb isotopic signatures for pollutant

Each solution of cadmium (Cd), lead (Pb), zinc (Zn), nickel (Ni), copper (Cu) and chromium (Cr(III)) with a concentration of 2 mg/L was shaken with the media. At a final pH of, limestone has significantly removed more than 90% of most metals followed by 80% and 65% removals using crushed bricks and gravel, respectively.

· Accumulation of Cu, Zn, Cd, and Pb in the sediment of seagrass ecosystems was examined using mesocosm experiments containing Zostera marina (eelgrass) and reference pools. Lead was approximately 20-fold higher in the surface sediment in the eelgrass pool than in eelgrass leaves and epiphytes on the eelgrass leaves, whereas zinc and cadmium were significantly lower in the surface
Subsequently, the adsorption affinity order was matched with Pauling's electronegativity order, which are Cu (), Zn () and Pb () 70 and reverse order of hydrated radius, Cu ( Å), Zn ( Å) and Pb ( Å). 71 The data indicated that higher electronegativity and smaller hydrated radius ensured a more favorable adsorption through surface complexation or adsorption reactions.
The Pb(ii)–Cu(ii), Pb(ii)–Zn(ii) and Cu(ii)–Zn(ii) binary aqueous system was prepared by mixing pairs of metal ions with equal initial concentration and the total initial concentrations of the two metal ions were kept in the range of 150 to 1000 mg L −1. After the adsorption process, the solutions were filtered and the residual concentration of heavy metal ions in the solution was
