 Oil spill
 Mining activity
 Garbage
 Conclusion
 Reference

3.  Waste can be defined as any
unwanted materials, which are
disposed off or are required to
be disposed.
 They are generated during the
extraction and processing of
raw materials and
consumption of final product
and other human activities
 Anthropogenic contamination
of the environment may be
defined as the chemical and
biological contamination
caused by the action of human.

4. Its increase is intimately
associated with the rise in
global population,
industrialisation,
urbanisation, and intensive
agricultural practises.
Some of the waste created by
anthropogenic activities are:
1) Oil spill
2) Mining activity
3) Garbage

5.  An oil spill is the release of a liquid
petroleum hydrocarbons into the
environment due to human activity. And it is
a form of pollution.

7.  Reduction in dissolved oxygen
– oil films are able to retard
significantly the rate of oxygen
uptake by water.
 Reduction in light penetration
– oil slick decreases the light
intensity up to 90%
 Smothering – Smothering coats
of oil have killed lichens and
algae along the shore line.

10.  Mining is the extraction of
minerals and metal from the
earth.
 The environmental effect of
mining includes erosion,
formation of sink hole, loss
of biodiversity and
contamination of soil,
ground water and surface
water by various chemicals
from mining processes.

14.  Surface burning is the
combustion of mined
waste material which
produce smokes, haze,
heat or venting of
hazardous gases, it
destroys the
surrounding vegetation
and pollute the nearby
area.

15.  Mining especially coal may
result in release of Methane
& CO2, a dangerous green
house gas which is
responsible for Climate
Change.
 Acid Mine Drainage (AMD) or
Acid Rock Drainage (ARD)
water that is discharged
from mining and mine
related operations contains
high levels of dissolved iron
and aluminum sulfates in
conjunction with pH values
less than 4.5.

16. it is produced when oxygen
dissolved in water reacts with
pyritic materials found in
association with most coal
deposits. AMD degrades the
water quality of stream and
supplies often to the point of
eliminating all biological
activity within the stream
contaminated with AMD.

17.  It is very harmful to our
environment because of the way
it is currently being disposed
 It possess dangerous risk to our
land, water and air
 Landfill disposal if leaked, will
contaminate surface and ground
water which in turn will travel to
the nearest ocean or lake and
poison the wildlife there.
 Incinerating trash has bad effect
on the environment as it
contributes to air pollution
which causes global warming.

18.  Sewage water poured into ocean poison fish and
other marine life.

19. Land fills overfilling with garbage destroy profitable land.
It takes many year to regain the nutrients and land
destroyed.

21.  Anthropogenic waste is exclusively created by man
 It is created by his activity like mining and
accidentally like oil spill, jeopardizing the
environment in ocean
 Garbage can be recycled and its production can be
reduced by looking for minimum packing at the
stores, choosing aluminum, tin and paper because
it can be recycled.
 Oil spill can be removed from the sight using
various bacteria known as super germ which helps
in breaking components of crude oil , it is eco-
friendly. Example: Pseudomanas
