Green Metals are Eco-Friendly because they can reuse and generate less carbon in the environment. Protecting the environment has become a serious issue, everyone should understand this problem and take this seriously, everyaware citizen should use only those metals which are less harmful for the society such as steel aluminium.
Faced with more and more stringent environmental regulations, nowadays heavy metals are the priority pollutants of surface and ground waters. Water contamination with these compounds is becoming one of the most serious environmental problems because of the toxic nature of the heavy metal ions, even at low trace levels.
Aluminium is called the green metal because it is a very environmentally friendly metal. Recycling this material saves 95% of the energy required to produce aluminium from raw materials. This means it plays a key role in human ecology.
Steel is not harmful in any sort, the goodness of this metal is driven by its quality. Stainless steel is basically a metal alloy, which is a mix of chromium, nickel, silicon and carbon.
A heavy metal blood test is a group of tests that measure the levels of potentially harmful metals in the blood. The most common metals tested for are lead, mercury, arsenic, and cadmium. Metals that are less commonly tested for include copper, zinc, aluminum, and thallium.
Some metals are toxic when they form poisonous soluble compounds.Most often the definition of toxic metals includes at least thallium, cadmium, manganese, lead, mercury and the radioactive metals. Metalloids (arsenic, polonium) may be included in the definition.
Levels above 60 µg/L indicate increased absorption, serum levels above 100 µg/L are potentially toxic, and serum levels above 200 µg/L are usually associated with clinical symptoms and signs of toxicity.
So the result is that Green Metals are eco unfriendly and they do not damage the environment.
