WASTE ON THE
ENVIRONMENT
water pollution
fires
short-term effects
long-term effects
Some hazardous
waste is flammable. It
has the potential to
ignite or explode,
causing a fire.
FIRES
substances produce
toxic effects after just
one release — this is
what we refer to as
“__________”.
SHORT-TERM
EFFECTS, acute toxicity
Long-term effects on
the environment
include signs of
mutation in animals
and other organisms.
This is also called
“_____________”.

EFFECTS, chronic toxicity
HAZARDOUS
WASTE DISPOSAL
PRACTICES
Underground disposal
Landfill disposal
Ocean dumping
Deep-well injection
Surface impoundments
Incineration
Encapsulation
Macroencapsulation
-strong and cost-effective option
-medical treatments, laboratory experiments,
nuclear fuel production, or radioactive ore
mining.
Underground disposal
-most common and oldest method
not intended for liquid waste
Landfill disposal
-to prevent groundwater contamination
Ocean dumping
-pumps liquid hazardous waste deep into the
earth
Deep-well injection
-depressions used to treat/store/dispose
hazardous waste (liquid)
Surface impoundments
-burns hazardous waste at high temperatures
Incineration
-encloses hazardous waste in a solid material
to prevent the release of contaminants into the
nvironment
Encapsulation
- encloses lage volumes of hazardous waste i
Macroencapsulation
