| Every computer component
has a life span after which it
needs to be replaced. Once you
replace a component, you need
to know how to dispose of it.
You cannot dump all of these components
in landfills, because some components,
such as CRTs, batteries, wiring,
and toner cartridges, contain
harmful chemicals. Monitors contain
several carcinogens and phosphors,
as well as mercury and lead. Printers
contain plastics and chemicals
such as toners and inks. The computer
itself contains several lubricants
and chemicals as well as lead.
These chemicals can seep into
the water table and contaminate
our drinking water, resulting
in adverse effects on the central
nervous system of human beings,
animals, and plant tissues.
These chemicals also have adverse
effects on the environment.
To protect the environment
from these hazardous substances,
you need to dispose them of
by following the procedures
that are environment friendly
such as recycling the component
or substance.
