Engineer Syed Zaheer Abbas: What is environmental Engineering? What is Ecology?

6. Lecture # 1

7.  Introduction to ecology of
environment; Impact of technology on
ecology of system; The effects of
industrial pollutants on human
environments; Environmental impact
assessment & sustainable
development; Air pollution and its
control; Water pollution and its
control; Industrial waste water and its
control; Industrial noise pollution and
its control; Future requirements of
process industries and developments
under the constraints of diminishing
world resources and ecological
demands of human environment.

8.  The environment encompasses
the whole of life on earth and the
complex interactions that link the
living world with the physical
world. In a general sense, this
covers everything contained
within the air, land and
water. Sudden and dramatic
natural changes to the
environment have occurred, and
continue to occur, which have the
potential to upset the whole
balance of the Earth's ecosystem.

9.  To increase individual’s
awareness level by
Objective
providing information
that will encourage to
change the behavior and
decrease the chance for
an unpleasant event.
 Reduce injuries and
illnesses and in
maintaining a safe
working environment.

10.  Provide us with a
structured system for
Objective
identifying
hazards, assessing risks
associated with those
hazards, putting in place
measures to control the
unacceptable risks and to
review the control
measures to ensure they
are effective and have not
introduced new hazards.

11.  The environment
encompasses the
whole of life on earth
and the complex
interactions that link
the living world with
the physical world

12.  Environmental engineering
is the application of
science and engineering
principles to improve the
environment
(air, water, and/or land
resources), to provide
healthy water, air, and land
for human habitation and
for other organisms, and
to remediate polluted
sites.

13.  Science…improve our
understanding of
natural processes
 Engineering…use this
understanding to
develop and apply
technologies that will
maintain or improve
environmental quality

14.  POPULATION
 A population is one
species living in a
specific area.
 For example, all foxes
living in an area form a
population.

15.  COMMUNITY
 A community is formed
from all living populations
found in an area.
 All the
foxes, dandelions, grassho
ppers, snakes, hawks, deer
, and skunks living in one
area each form their
individual
populations, but together
make up a community

16.  ECOSYSTEM
 An ecosystem is
formed by the
interactions between
all living and non-
living things

17.  Ecology is how living
and non-living things
affect each other in
their environment.

18.  Buildings
 Roads
 Bodies of water
 Automobiles
 Traffic lights

19.  The introduction of
substances or energy
into the
environment, by
people, liable to
cause harm to living
creatures or
ecological systems.

20.  How did pollution begin?
1. More sophisticated
lifestyles.
2. Growing needs of people.
3. Accelerated rates of human
and economic activities.

21.  Waste becomes
pollution if the level
discharged exceeds
the capacity of the
environment to
absorb it without
adverse effect.

22.  The types of pollution
that we are going to
look at:
 Air Pollution
 Water Pollution
 Land Pollution
 Noise pollution
 Thermal pollution
 Radiation pollution

23.  Air pollution is the
introduction of
chemicals, particulate
matter, or biological
materials that cause
harm or discomfort to
humans or other living
organisms, or cause
damage to the natural
environment or built
environment, into the
atmosphere

24.  Water pollution is
the contamination of
water bodies (e.g.
lakes, rivers, oceans
and groundwater).

25.  Land pollution is the
degradation of
Earth's land surfaces
often caused by
human activities and
their misuse of land
resources.

26.  Noise pollution is
excessive, displeasing
human, animal or
machine-created
environmental noise
that disrupts the
activity or balance of
human or animal life.
