Pollution

Pollution


There are different types of pollution, but there is one definition,
which covers all forms:

pol·lu·tion

(p[IMAGE]-l[IMAGE][IMAGE]sh[IMAGE]n)
n.

1. The act or process of polluting or the state of being polluted,
especially the contamination of soil, water, or the atmosphere by
the discharge of harmful substances.

2. Something that pollutes; a pollutant or a group of pollutants:
Pollution in the air reduced the visibility near the airport.


Different Types
---------------

The four main types of pollution which are currently affecting Cairo
are noise, air, land and water.



Air Pollution in Cairo
======================

Cairo has a serious air pollution situation due to motor vehicles and
industry. The city government frequently monitors air pollution to
measure concentration of noxious gases. In addition, it utilizes all
forms of media to promote environmental conservation within the city,
including celebrations like the annual Nile Inundation to encourage
environmental awareness.

Modern Cairo Traffic

Air quality in Greater Cairo is a major concern to the Government of
Egypt, particularly with regards to adverse health impacts.

What is the cost of air pollution In Cairo?
The World Health Organization reports that the Air Pollution in
Downtown Cairo is 10-100 times what is considered a safe limit. Cairo
is in the company of other Cities like Mexico City, Bangkok, San
Paulo, Delhi, Tokyo which are among the worst Cities in the World in
terms of air pollution.

CairoAssuming Cairo has a population of 12 million, The simple risk
calculation comes to the conclusion that : half a million of the Cairo
residents will develop in a period of 5-25 years serious health
problems (respiratory diseases and cancer ) that will result in
premature death. That is one person out of every twenty-four persons
living in Cairo. That person can be a member of your family, a
relative or a friend. This is caused by air pollution due to
particulate in air alone.

More than one million vehicles are on the streets of Greater Cairo,
and that number grows significantly each year. Egypt's Environment Law
4 of 1994 established standards for vehicle emissions to reduce carbon
monoxide and other harmful substances that have the greatest impact on
human health. CAIP's Vehicle Emissions Testing, Tune-Up, and
Certification (VET) component is working to reduce emissions of
harmful air pollutants from motor vehicles and improve fuel
efficiency. The program will be implemented gradually. As agreed
between the Ministries of Environment and Interior (traffic
Authority), the first phase of the VET program will test vehicle
missions on the road, using mobile analysers.

Noise Pollution in Cairo

Things like cars, and people, and the city area, with nightclubs and
boom cars cause noise pollution.

Today's Dallas Morning News (6/26/97) has an

AP story about an Egyptian government campaign

to warn citizens about the "dangers of noise

pollution and [to] soften them up for what it says

comes later: fines from traffic police and the

newly created environmental police."



"Noise has become the problem and illness of

the era" says an ad from the Environmental Affairs

Agency.



The campaign is aimed at reducing the maddening

honking that is a near constant on Cairo streets, the

clanging at construction sites, and the blair of loudspeakers

that broadcast the Islamic call to prayer five times a

day.







The government has banned the import of the loudest

type of auto horns.



The article did not mention boom cars. Maybe the

Egyptians are lucky enough not to have been afflicted

by this plague.

Water Pollution

GOALS

The Institute's mission is the rational protection and development of
the River Nile in a sustainable scientific manner.

The main objectives are:

1. Control of the quality of the River Nile water and Lake Nasser

2. Protection of the existing barrages

3. Development of navigation

4. Protection of bank erosion

5. Utilization of the sediment deposited in the Aswan High Dam

INSTITUTE ACTIVITIES

The following studies are being conducted by the Institute:

Monitoring and Evaluation of the sedimentation in Lake Naser and its
effect on the reservoir storage capacity and Aswan Dam operation

Study of the fluvial characteristics of the River Nile and changes in
the river regime

Assessment and prediction of the effect of fluvial hydraulic and
hydrological changes on the major hydraulic structures of the Nile and
on the various uses such as irrigation and hydropower generation

Preparation of studies and projects required for the protection and
development of the River Nile, including their economic, environmental
and social impacts

Development of the techniques to delineate and improve lands within
the river training and management lines

Evaluation and assessment of the impact of new developments and
interventions on the River Nile channel, water quality, and shoreline

Development of technologies for river bank protection and river front
improvement for rural, urban and tourist centers along the Nile

Monitoring of water quality in the river main channel and its
pollution sources for chemical, physical and biological
characteristics

Assistance in enforcement of pollution control laws related to Nile
waters

Monitoring of water quality in the Nassau for chemical ,physical and
characteristics

Application and Development of numerical models to study sediment
transportation along the River Nile and estimate water surface
profiles for different scenarios of water management policy

Studying the High Dam effect on seepage and ground water

Development of database system that include data related to hydraulic,
hydrologic, morphological changes, and water quality of the Nile River
and Lake Nasser

GIS Development and application using topographic and hydrographic
data for studying morphological changes and water quality monitoring
along the Nile River

Producing bathymetric charts of the Nile River

Producing of Navigation charts

Dissemination of information and data emanating from studies, research
results, and from publications, conferences, symposia or other media

Exchange of data information with national, regional and internal
organizations with shared interests

EXPECTED OUTPUTS

Evaluation of the side effects of the Aswan High Dam on the Nile River
channel and surrounding environment Solution of problems regarding:

Degradation.

Sedimentation.

Water quality.

Water pollution.

Protection of the existing Nile control works and proposed new
hydraulic structures for generation of energy and Nile improvements.

Navigation waterway improvements

Nile side-slope stability and protection of agriculture lands from
erosion

Island generation along the Nile course

Drop in water levels on the River Nile and the three main canals

Land Pollution

At the moment, the land in cairo is being polluted, by sewage,
factories dumping chemicals, straw burning and other things.

[IMAGE]In the unserved areas, where on-site sanitation is practiced,
the most common type is a simple leaching pit. If the prevailing type
of soil and groundwater permit deep percolation, wastewater reaches
the groundwater table carrying all types of pollutants. This condition
is more severe than leaking sewers with respect to groundwater
pollution due to the fact that pit wastes are more concentrated in
both organic and inorganic loads. If the soils and groundwater do not
allow percolation, the accumulated wastewater is regularly emptied by
vacuum trucks which deposit their loads into the nearest channel or
agricultural land. A more serious condition may arise if regular
emptying is not available, as it necessitates inhabitants entry into
the pit for manual removal of sludge.

Solutions

[IMAGE]

Natural gas is a fossil fuel extracted from underground reservoirs,
where it was formed millions of years ago from organic matter.
Tremendous pressure from the overlying rock, combined with the earth's
heat, converted the organic matter into fossil fuels, including coal,
oil, and natural gas. Coal is solid, oil is liquid, and natural gas is
a vapor, like air. Natural gas is composed primarily of methane (85 to
95 percent). It also contains other hydrocarbons, such as ethane,
propane, and butane, and other gases, such as carbon dioxide,
nitrogen, and helium.

When a network of vehicle emission testing stations and a
technical/training center have been completed, emission testing will
become part of the routine license renewal procedures. Meanwhile, CAIP
is enhancing the low emissions tune-up capacity in the vehicle repair
sector.


Lead pollution abatement

Environmental studies show that lead is a major component of air
pollution in Cairo. The Lead Pollution Abatement component (LPA)
supports implementation oof the Government of Egypt's Lead Smelter
Action Plan. The government is taking positive steps to decrease lead
pollution by making lead-free gasoline available to the public and
through the implementation of other action plans. However, lead
particles emitted from heavy transport vehicles and lead smelters arc
in excess of the maximum permissible limit defined by the law.

Air quality monitoring

CAIP established the Air Quality Monitoring Program (AQM) to measure
lead (Pb) and fine particulate matter (PM) levels in Greater Cairo's
ambient air. By August 1998, a 36-station monitoring network, ranging
from Kaha in the north to Tebbin in the south, was installed and
operating. The sites are in heavily trafficked, residential, urban,
and industrial areas. Several sites provide background data, measuring
Pb and PM levels before the air reaches Cairo.
