Metals play a vital but complex role in human life. They are essential to many modern technologies and objects we depend on daily, but can also be toxic to human health in certain forms or quantities. While metals cannot be removed from our lives due to their usefulness, their toxic effects mean we must carefully manage their production and disposal. Metals are both hugely beneficial yet also potentially harmful, so a balanced approach is needed.

malleability, which readily loses
electrons to form positive ions. Metals are
otherwise defined according to their position on

IMPACT OF METALSMetals Are Vital
Metals are vital to human life...
-Without metals, the objects
we depend on every day,
including the computer we
are using simply could not exist!
-Metals are infinitely recyclable
, with no loss of properties!
-The non-ferrous metals industry actually contributes to climate
protection!
-Metals play a key role in medicine: combating cancer, diabetes,
strokes, etc.
-Around 80% of the earth's elements are metals!
We cant Imagine a world without metals !!!

5. Metals are the oldest toxin known to man.
They are present in the rocks and ores. Rain
water dissolves them and distributes them in
the environment. We get exposed to them
because we use them for various purposes.
Health effects due to exposure to metals could
range from skin lesions to cancer. Metals can
be classified into four different groups.
How Metals Become Toxic?

7. CONCLUSION
THEREFORE METALS ARE TOXIC
AND THEY CAN BE VERY HARMFUL
TO US,BUT WE CANT EVEN
IMAGINE OUR LIFE WITHOUT
THEM BECAUSE THEY ARE MUCH
USEFUL THEN HARMFUL.
