 · To determine the source of heavy metals (natural and anthropogenic), simple and multivariate statistical analyses were applied. According to factor analysis, three factors were determined. The first factor consists of SiO2, Al2O3, Na2O, K2O, TiO2, Cr, Ni, Cu and Mo and total variance is explained with 27.502% and expressed as "natural process factor".

Environmental Contamination by Heavy Metals | …

 · The environment and its compartments have been severely polluted by heavy metals. This has compromised the ability of the environment to foster life and render its intrinsic values. Heavy metals are known to be naturally occurring compounds, but anthropogenic activities introduce them in large quantities in different environmental compartments. This leads to the environment''s ability to ...

Heavy Mineral

Minerals with a density greater than 2.87 are referred to as heavy minerals and can be separated from commoner minerals such as quartz, feldspar, and calcite using a "heavy liquid" separation. A liquid with a SG of 2.87 or above is placed in a separating funnel, and the sample introduced.

Heavy metals

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be ...
