Tungsten provides a unique contribution, as it imbues exceptional strength, corrosion resistance, and other useful properties to base metals. Besides being a great alloying element, tungsten can also be the base for its own alloys, and this article will highlight the basic egories of these tungstenbased alloys.
· Tungsten is not found, with this technique, in the control samples, which were collected more than 4 km away from the old wash site and more than 8 km away from the new wash site. Although the concentration of Pb in the collected plants does not exceed the WHO maximum values, the same cannot be said about As, which is found in concentrations of up to 32 times the maximum value .
