3. T O GALVANIZE OTHER

METALS

To prevent corrosion

Galvanize means to put coating on iron

To make metals stop rusting for quite a long time

I NTERESTING F ACTS

Zinc is..

Found on roofs because it has a very high quality of roofing material

A metal we all need for life

Part of enzymes and many biological medicated processes

Easily reacted with acids to produce hydrogen

Very slow to oxidize

An interesting element because it is not a poisonous element, where the two other elements that are in the same group with Zinc, Mercury and Cadmium, are both pretty poisonous.

Something we need for us to survive

H AZARDOUS E FFECTS OF

Z INC TO THE E NVIRONMENT

Zinc production can cause:

Water pollution-it can cause for fish to be accumulated with Zinc which is able to bio magnify up the food chain

Soil pollution-farmlands could be polluted which can cause farm animals to absorb concentration that damages their health. It could also break down microorganisms and earthworms since their habitats are polluted.

Plants to have their system unstable, unhandled and uncontrolled

M ORE INFORMATION ABOUT

Z INC

In our body, if we don’t have enough Zinc, we are not able to smell things.

When you combine it with other elements, it could get quite frisky

Zinc is an abundant metal

An enzyme called ‘Carbonic Anhydrase’ needs Zinc to catalyze the reaction of CO2 and water
