Hazardous Waste
- anything which, because of its quantity,concentration, or physical, chemical or infectious
characteristics, may cause, or significantly contributeto an increase in mortality; or cause an increase inserious irreversible or incapacitating irreversibleillness; or pose a substantial present or potentialhazard to human health and the environment when
improperly treated, stored, transported, or disposedof, or otherwise managed

The Dirty Dozen
Persistent Organic Pollutants
Organic chemicals (mostly synthetic) that
remain intact in the environment for long
periods, become widely distributedgeographically, accumulate in the fatty tissue
of living organisms and are toxic to humans
and wildlife.
POPs circulate globally and can cause damage
wherever they travel

ID of a chemical
A technical document that providesinformation of that chemical
A simple and precise descriptions ofchemical properties
can be used as an instruction to thechemical substance
a basic tool for management of thechemicals.
= ID / birth
certificate
= MSDS or SDS
What is Material Safety Data Sheet ?

MSDS include information such as,
physical data
health effects
first aid
reactivity
storage
disposal protective equipment, and
spill/leak procedure.

Last Words
Pollution Prevention is better than End-of-Pipe
Approach
Cost of cleaning up the environment is greater
than cost of waste minimization.

Last Words
Everybody on earth is a Polluter and has an
individual impact on the environment.
Every polluter should be responsible for the
pollution he/she causes.
Every responsible polluter should be willing to
pay the price for mitigating his/her impact on
the environment.
