Toxins in a Computer
Computers have become a familiar fixture in everyday life, but these useful machines may carry a heavy price for their convenience. The various parts and internal components of computers contain toxic chemicals and materials that endanger the environment and other life if not disposed of properly. Exposure to these chemicals, through burning or improper landfill dumps, can cause multiple health concerns, which range from birth defects to cancer.

Computer Screens
-
Older cathode ray tube -- or CRT - computer monitors contain barium, and between 4 and 8 lbs. of lead within the glass to act as a radiation shield for the user. Barium exposure causes brain swelling and muscle weakness, and lead exposure can lead to brain and nervous system damage, as well as developmental damage to unborn babies. The lighting elements used for LCD monitors and screens contain mercury, which can lead to brain and kidney damage from prolonged exposure to high levels.
Casing
-
A computer's case and internal components are composed of up to 14 lbs. of plastic material, which contains polyvinyl chloride, or PVC, and brominated flame retardants, or BFRs. When these materials are burned, melted down or dumped into landfills, they release fumes and leach toxins into the environment, which can cause harm to developing fetuses or lead to cancer.

Internal Components
-
The internal components of a computer include a combination of dangerous chemicals and materials, such as PVCs for the circuit boards and wiring casings, and lead solder for the electric transistors. Chips and semiconductors can also contain cadmium, which causes cancer and concentrates within the body to cause kidney bone structure damage. The corrosion protection found on the steel housing of computers contains hexavalent chromium, which can damage DNA and cause asthmatic bronchitis.
Proper Disposal
-
To avoid exposure to these chemicals and the health risks that accompany them, properly dispose of your computer equipment once it reaches the end of its lifespan. Seek local companies that accept computers and the separate accessories, such as printers and print cartridges, for proper dismantling, recycling and disposal of the various components and parts. Laptop batteries are also recyclable, and most electronic stores such as Best Buy and Radio Shack accept them for proper handling.
