In today’s world there are a host of serious environmental problems exactly in recent years it has come to signify a wider range of disruptions to environmental quality.
Thus litter, billboards, and auto junk yards are said to constitute visual pollution; noise excessive enough to cause psychological or physical damage is considered noise pollution; and waste heat that alters local climate or affects fish populations in rivers is designated thermal pollution.
3. INTRODUCTION
• In today’s world there are a host of serious environmental problems exactly in
recent years it has come to signify a wider range of disruptions to environmental
quality.
• Thus litter, billboards, and auto junk yards are said to constitute visual pollution;
noise excessive enough to cause psychological or physical damage is considered
noise pollution; and waste heat that alters local climate or affects fish populations in
rivers is designated thermal pollution.

5. AIR POLLUTION
• The condition in which air is contaminated by
foreign substances, or the substances them selves.
• Air pollution consists of gaseous, liquid, or solid
substances that, when present in sufficient
concentration, for a sufficient time, and under certain
conditions, tend to interfere with human comfort,
health , and cause environmental damage.

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

7. LAND POLLUTION
• Land pollution is the degradation of Earth's land
surfaces often caused by human activities and
their misuse of land resources. It occurs when
waste is not disposed properly.
• Haphazard disposal of urban and industrial
wastes, exploitation of minerals, and improper
use of soil by inadequate agricultural practices
are a few factors.

8. RADIOACTIVE POLLUTION
• The radioactive pollution is defined as the
physical pollution of air, water and the other
radioactive materials.
• The ability of certain materials to emit the proton,
gamma rays and electrons by their nuclei is
known as the radioactivity.

9. VISUAL POLLUTION
• Visual pollution is an aesthetic issue and refers to
the impacts of pollution that impair one's ability to
enjoy a vista or view.
• Visual pollution disturbs the visual areas of people
by creating negative changes in the natural
environment.

15. BAN PLASTIC BAGS
• Tunisian government wants to ban plastic bags to protect the biodiversity of the
country and to end the “visual pollution”.
• The Environment Minister’s staff "has prepared a regulatory decree prohibiting
the export, distribution and manufacturing of non-biodegradable plastic bags”; said
the director of the division of the quality of life in the ministry, Hédi Chbili.

16. “SEBKHET SIJOUMI” LOOKS LIKE THE SHORES OF LAKE
• The Environment Minister, Mr. Nejib Derouiche said that from December 31, 2015
the wastewater would not be discharged into the “Sebkhet Sijoumi”.
• "We are preparing “Sebkhet Sijoumi” to be similar to the Lake North and South
Lake, and so can operate like an urban, environmental and economic space.”
• For remember: The Lake of Tunis was in the same situation by 80s and now it is a
source of pride and significant economic development.

17. REDUCE AIR POLLUTION
• The government took new action plans to reduce air pollution between 5 and 20% by 2020.
• These plans cover the establishment of a continuous monitoring platform in energy-intensive
companies and most polluting in Tunisia in order to ensure the effectiveness of the tools used in
the fight against pollution, like "filters ".
• Mr. Blouza the general director of the national environmental protection agency (NEPA) has
noted that the NEPA will intensify the cleaning process of polluting factories in different regions
in order to get rid of gas fumes arising from such factories which actively contribute to the
pollution.

18. CONCLUSSION
• It is true that the Tunisian government has started to take more seriously the
pollution problems in our country and search for effective solution to reduce
it.
• But, it is necessary to work more, especially on pollution garbage that invade
our streets.
