2. What is Mercury? Mercury is a liquid metal that has many uses.
Mercury is used in:
Mascara
Thermometers
Barometers
Electric switches
Dental fillings
Dry cell batteries
Flourescent bulbs
In gaseous form, it is highly toxic, and has many harmful effects.

3. Harmful Effects of Mercury to Humans
It’s a cumulative poison, meaning it collects inside of the body. It doesn’t break down.
Most toxic in gaseous form
Damages central nervous system, brain and kidneys
Alters the genetic and enzyme systems
Minimata disease – a neurological syndrome caused by intense mercury exposure

4. Harmful Effects of Mercury to the Environment
Animals who eat fish contaminated with mercury are affected the same way as humans.
Animals affected by mercury can suffer from:
Impaired vision and hearing
Impaired growth
Death
Involuntary muscle movements
Inability to reproduce
Weight loss

5. Technologies’ Influence
Positive Influence
Scientists are able to find a way to invent a type of gadget in which it contains mercury to exterminate bacteria and fungus
Technology is used to filter the mercury-contaminated waters so it will again be safe for human and animal exposure
Negative Influence
World becoming advance = more power plants and more products that contain mercury
Products include batteries, computers, appliances, etc
Others include power plants, factories, farms, etc
Power plants, farms and factories pollute air and contaminate the water with mercury
