Biological pollution refers to the introduction of harmful, non-native organisms into an environment by human activity. Some common types of biological pollutants include bacteria, viruses, insects, and pollen. These pathogens can spread diseases in humans and animals. Sources of biological pollution include sewage, contaminated air systems, animal droppings, and the introduction of invasive species. To reduce biological pollution, it is important to properly clean humidifiers, limit exposure to allergy-causing materials, control invasive species, get vaccinated, and prevent the spread of pathogens.
3. What are Pollutants?
• Any harmful substance/
organism coming from living
organisms or by itself,
effecting the lives of
organisms living in a particular
environment.
4. What is Biological Pollution?
› An impact or change in aquatic or
terrestrial environment by Human
activity
Introduction of non-indigenous and
invasive species in environment.
10. Biological Pollutants
Consists of pathogens (disease-causing
agents)
Come from sewage
• Diseases include;
-Typhoid, cholera, dysentery, polio,
infectious hepatitis, salmonella, E-Coli
bacteria
11. Health effects by Bio Pollutants:
▸ Asthma
Lethargy Allergic reaction by repeated exposure to an
allergen > humidifier fever, associated with exposure to
toxins from microorganisms › Legionella and influenza
are known to be
transmitted by air.
12. Sources of of Bio pollution:
Viruses are usually transmitted from infected people or
animals.
Bacteria are transmitted by debris, contamination,
mosquito etc.
› Contaminated central air handling systems can be
breeding grounds for mold If an invasive specie
introduced or enter by chance in an environment
Droppings and body parts from Cockroaches,rodents.
13. How to reduce Bio Pollution...?
•Avoid having allergy-causing animals in
homes.
• Clean portable humidifiers every third day.
Minimum introduction to invasive species
• Don't get contaminated yourself
• Vaccination.
14. What is biological pollution control?
Biological processes are regarded as
promising and sustainable. The bio-parts of
pollutants are degraded through microbial
activities, where complex organic matters
are degraded and nutrients such as
nitrogen and phosphorus are removed.
Archaea and bacteria are important in such
processes.
15. How is biological pollution prevented?
Use dehumidifiers and air conditioners,
especially in hot, humid climates, to reduce
moisture in the air, but be sure that the
appliances themselves don't become
sources of biological pollutants. Raise the
temperature of cold surfaces where
moisture condenses. Use insulation or storm
windows.

pollution level.
• It translate the existing data on
miscellaneous invasive alien species
impacts into uniform bio pollution
measurement units.
