BIO-MEDICAL WASTE: -
Any waste

beings or animals or in
research activities
pertaining thereto or in
the production or testing
of biological.

CAUSES
CLASSIFICATION OF BIOMEDICAL WASTE:
CLASSIFICATION OF BIOMEDICAL WASTE:
1. INFECTIOUS WASTE:
waste
to contain
(bacteria,
parasites, or
Infectious
suspected
pathogens
viruses,
fungi) in sufficient
quantity to cause diseases
in susceptible hosts.
continue…
This category includes:-
• Cultures and stocks of
infectious agents from
laboratory work.
from surgery on
with infectious
• Waste
patients
disease.
• Infected animals from
laboratories.
2.PATHOLOGICAL
WASTE:
body
It consists of tissues,
parts,
fetuses, and
organs,
human
animal carcasses,
blood, and body fluids.
3. SHARPS:
These are the items that
could cause cuts or puncture
wounds, including;
Needles,
Scalpel and other blades,
Knives,
Infusion sets,
Saws,
Broken glass, and nails.
4.PHARMACEUTICAL
WASTE:
It includes expired, unused,
spilt, and contaminated
Pharmaceutical products,
Drugs,
Vaccines, and sera
5. GENOTOXIC WASTE:
highly
• Genotoxic waste is
hazardous and may have;
Mutagenic,
Teratogenic, or
Carcinogenic properties.
• It raises serious safety problems,
both inside hospitals
disposal, and should
and after
be given
special attention.
• It includes certain cytostatic
drugs, vomit, urine, or feces from
patients treated with cytostatic
drugs, chemicals, and radioactive
material.
6. CHEMICAL WASTE:
It consists of discarded
Solid,
Liquid, and
Gaseous chemicals
Chemical waste may be hazardous or nonhazardous.
It is considered to be hazardous if it has at least one
of the following properties:
Toxic,
Corrosive (acids of pH < 2 and bases of pH> 12)
Flammable,
Reactive
Genotoxic
7. WASTES WITH HIGH CONTENT
OF HEAVY METALS:
It represents a subcategory of
hazardous chemical waste, and is
usually highly toxic.
It includes
Batteries,
Broken thermometer,
Blood-pressure gauges.
8. PRESSURIZED CONTAINERS:
Many types of gas are used in
health care, and are often stored in
pressurized cylinders, cartridges,
and aerosol cans.
Most common gases used in health
care includes:
Anesthetic gases
Ethylene oxide
Oxygen
Compressed air
9. RADIOACTIVE WASTE:
It includes the X- rays, α- and β-
particles, and γ- rays emitted by
radioactive substances.
are heavy
charged, and
protons and
• α-particles,
positively
include
neutrons.
• They have low penetration
power, and are hazardous to
humans mostly when inhaled
or ingested.
positively charged electrons with
significant ability to penetrate
human skin, they affect health
through ionization of intracellular
proteins and proteinaceous
components.
• γ- Rays, are electromagnetic
radiations similar to X- rays but to
• β- Particles, are negatively or
shorter wavelength. Their
penetrating power is high and lead
shielding is required to reduce
their intensity.
SOURCES OF BIOMEDICAL WASTE:
care
• It is generated primarily from health
establishments, including
• Hospitals,
• Nursing homes,
• Veterinary hospitals,
• Clinics and general practitioners,
• Dispensaries,
• Blood blanks,
• Animal houses and research institute.
2. INDUSTRIES, EDUCATION INSTITUTES AND
RESEARCH CENTERS:
 These also generate bio-
medical waste in substantial
quantities.
 The type of waste generated
from an animal houses is
typically animal tissues,
organs, body parts, carcasses,
body fluids, blood etc., of
experimental animals.
3. BLOOD BANKS AND
CLINICAL
LABORATORIES:
Blood banks and
laboratories generate
most of the categories
of biomedical waste.
4.HEALTH CARE
ESTABLISHMENTS:
The sources of bio-medical
waste generated in
health care setting.
EFFECTS OF BIOMEDICAL WASTE: -
The
management
improper
of
biomedical waste causes
serious environmental
problems in terms of
Air,
Water and
Land pollution.
1. AIR POLLUTION:
• Air pollution can be caused in both indoors
and outdoors.
generates air
• Biomedical waste that
pollution is of three types-
• Biological,
• Chemical and
• Radioactive.
A. Indoor air pollution:-
Hospital Acquired Infections
(Nosocomial infection).
Indoor air pollution can
caused due to:
• Poor ventilation
• The paints, carpet,
furniture, equipment’s, etc.,
used in the rooms.
• Use of chemicals,
disinfectants, fumigants etc.
3. LAND POLLUTION:
• Open dumping of biomedical waste
is the greatest cause for land
pollution.
• Soil pollution from bio-medical
waste is caused due to infectious
waste, discarded medicines,
chemicals.
• Heavy metals such as cadmium,
lead, mercury, etc., which are
present in the waste will get
absorbed by plants and can then
enter the food chain.
