The document discusses different types of environmental pollution including air, water, and soil pollution. It outlines how air pollution from smoke, vehicle exhaust, and forest fires can introduce chemicals and particulate matter into the air that cause respiratory diseases and infections in humans. Water pollution occurs when factories and oil spills discharge pollutants into bodies of water without treatment, which can weaken the immune system and lead to diseases like diarrhea, typhoid, cholera, and dysentery when consumed. Soil pollution is typically caused by industrial activity and agriculture and introduces chemicals like petroleum, heavy metals, and pesticides into the soil.

2.  Introduction
 Biotic and Abiotic factors
 surroundings

3.  Introduction
 Environmental pollution is the contamination of physical and
biological components of the earth/atmosphere to such an extent
that normal environmental process are adversely affected

6.  Air pollution is the introduction
of chemicals, particulate matter, or biological
materials into the environment that cause
discomfort, disease, or death to humans, damage
other living organisms such as food crops, or
damage the natural environment or built
environment .
 Smoke from chimneys, automobile exhaust,
burning of fossil fuels and forest fires result in air
pollution

7. Water pollution is the contamination
of water bodies
(e.g. lakes, rivers, oceans, aquifers and
groundwater). Water pollution occurs
when pollutants are discharged directly or
indirectly into water bodies without
adequate treatment to remove harmful
compounds

8.  Wastes of factories refineries and waste
treatment of plants
 Oil spills

10.  Soil contamination or soil pollution is caused by the presence
of xenobiotic (human-made) chemicals or other alteration in the natural soil
environment. It is typically caused by industrial activity, agricultural
chemicals, or improper disposal of waste. The most common chemicals
involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons
(such as naphthalene and benzo(a)pyrene),solvents, pesticides, lead, and
other heavy metals. Contamination is correlated with the degree of
industrialization and intensity of chemical usage.

11.  the bodily system that protects the body from foreign
substances, cells, and tissues by producing the immune
response and that includes especially the thymus, spleen,
lymph nodes, special deposits of lymphoid tissue (as in the
gastrointestinal tract and bone marrow), macrophages,
lymphocytes including the B cells and T cells, and antibodies

12.  Diseases
 A deleterious change in the body’s
condition in response to environmental
factors
 Diseases like
 Skin allergies
 Respiratory infections
 Asthma
 Lung cancer

13.  Inhalation of polluted air can cause cardio respiratory diseases
 Breathing polluted air can also cause widespread inflammation
by triggering the release of white blood cells from bone marrow
into the blood stream. The influx of white blood cells can alter
the integrity of the blood vessels. The white blood cells are then
absorbed into fat tissues where chemicals are released that
cause inflammation.
 These particulate matter stimulates inflammation in the lung, and
products of that inflammation spill over into the body's circulation,
traveling to fat tissue to promote inflammation and causing vascular
dysfunction,

14.  More ozone pollution exposure lead
more asthma attack

15.  Ozone reduces lungs function
 Ozone : other symptoms
 Allergy symptoms
 Respiratory infections
 Ear infections
 Emphysema attack
 Overall death rate

16.  Penetrate deeply into the lungs to alveoli
 irritate lung linings- more asthma
 stimulate immune system inflammatory
proteins

17.  Drinking polluted water weaken immune
system
 A weakened immune system can be a
result of having an organ transplant,
having HIV or AIDS or from undergoing
chemotherapy.
 A weaker immune system means a
higher likelihood of contracting disease
from waterborne contaminants

18.  Diarrhea
 Typhoid
 Cholera
 Dysentry
 Measles
