BULLETIN BOARD
First Ozone and Pollution
Monitoring Ground Station for
West Asia in Qatar
-
An advanced cutting-edge
monitoring station, able to
gather crucial data on
pollution linked with damage
to the Earth's ozone layer
is to be established in the
State of Qatar.
-
The station, the first in
West Asia, will plug serious
and significant ground and
satellite-data gaps in the
regional and global
atmosphere monitoring
networks.
-
Currently the nearest
similar ozone monitoring
stations are between 800km
and 3,340km away in Esfahan
(Iran) and Nairobi
respectively.
-
For halocarbon measurements
the nearest stations are in
central Europe (more than
4000 km away) and China
(more than 6000 km away).
-
Scientists believe the new,
more advanced station will
assist in understanding
whether the ozone layer -
the thin layer of gas that
surrounds the planet and
protects all life on Earth
from the sun's harmful rays
- is actually recovering
after decades of chemical
attack.
-
Under the UN Environment
Programme's (UNEP)Montreal
Protocol, over 90 per cent
of ozone damaging gases have
already been phased out and
it is predicted that the
layer might have fully
recovered by somewhere
around the 2060s as a result
of past, current and future
actions.
-
But, without direct
scientific observations
around the world governments
cannot know whether
improvements are genuinely
taking place or whether
there is a need to step up
or re-focus the response.
-
The decision to establish
the new ground station
follows discussions between
the Government of Qatar,
UNEP's ozone secretariat and
the Qatar Foundation.
-
The announcement on the
station was made by the
Government of Qatar, during
the high level segment of
the 8th Conference of the
Parties to the Vienna
Convention and 20th Meeting
of the Parties to the
Montreal Protocol.
-
NASA, the US space agency
will be working with the
Government of Qatar on the
project too.
-
The ground station will
assist space agencies to
validate Earth Observing
satellites proofing the data
they gather on behalf of
researchers right around the
globe.
Ozone and Climate Friendly
Advanced Technology Centre
-
Qatar also announced plans
to establish a global centre
of excellence for research
and development of ozone and
climate friendly technology,
equipment and appliances.
-
Last year governments agreed
to accelerate the freeze and
phase-out of replacement
chemicals known as HCFCs in
large part because of their
global warming potential.
-
Experts believe the maximum
contribution of the phase
out will come by introducing
new, low or zero global
warming gases backed by new,
energy saving equipment -
one of the issues which the
new centre seeks to resolve.
-
The Government of Qatar and
its ministry of the
environment are to hold
discussions with UNEP
including its West Asia
office in Bahrain on how
best to design the centre
and its research programme,
with a view to having the
centre up and running in
three to five years.
-
Achim Steiner, UN
Under-Secretary General and
UNEP Executive Director,
said," Sound science
underpins sound
decision-making. Big data
gaps exist for a range of
key issues, from climate and
ozone to particles and
aerosols in the air and
atmosphere, in several
regions. These include
Siberia and large parts of
Africa including the Congo
River Basin'.
-
"However, the very welcome
announcement by Qatar will
help plug key data gaps
relating to information
gathering in West Asia and
the Gulf to the benefit of
the region and the world. In
doing so, the Government is
putting its commitment to
boosting the globe's
science-based firmly on the
international radar," he
added.
-
The data collected and
analysed at the new
observatory in Qatar will be
archived at various
international data centres,
such as the World
Meteorological
Organization's World Ozone
and UV radiation Data Centre
(Canada) and World Data
Centre on Greenhouse Gases
(Japan). The data will
thereby be available for the
global scientific community.
-
Waleed Al-Emadi, a senior
ozone expert at the Qatar
Ministry of the Environment
said," The government of
Qatar is committed to
developing a
knowledge-based,
scientifically advanced
society and one that echoes
to the national and
international challenges of
the 21st century.
-
"Our commitment to
atmospheric monitoring and
to research on ozone and
climate-friendly
technologies is part of this
evolution and
diversification of the
Qatari economy both of which
should prove a milestone in
our country's scientific,
cultural and environmental
transformation," he said.
Environmental impact of
seawater use in industry
discussed at conference
-
The environmental impact of
the use of seawater in
industrial cooling as well
as discharges from
desalination and power
plants to the Gulf waters
were discussed at an
international conference.
-
The second international
seawater conference, held
under the patronage of the
Ministry of Environment
featured presentations by
experts from Qatar, the UK,
US, the Netherlands, India,
World Bank and several GCC
countries.
-
Giving a presentation on
discharges from desalination
and power plants, Thomas
Hoepner said, there is an
urgent need for a standard
of ecological impact
assessments and a
supra-national coordination
of the water and electricity
grids, which are currently
lacking in the region.
-
The total loads of the main
chemical discharges in to
the sea from desalination
plants in the region per day
amount to 66,000kg of
antiscalants, 24,000 kg of
chlorine, and 300kg of
copper.
-
"The localization of
desalination and power
plants so far seems be
directed by the locations of
the demand for energy and
desalted water and not by
the selection of minimal
marine ecological damages,"
said the speaker.
-
A joint presentation by
experts from Qatar
University and the Texas A&M
University discussed the
problem of residual chlorine
in seawater cooling. In
Qatar. huge volumes of sea
water are used for cooling
every day and discharged
back to the Arabian Gulf
waters. Chlorine is added to
the seawater to control
biofouling of the cooling
system.
-
The added chlorine reacts
with bromide and other
compounds in the water to
produce a wide range of
chemical oxidants. Some of
these oxidants remain in the
cooling water after it is
discharged and poses a major
environmental burden.
-
New regulations have
recently been established in
Qatar which specify that the
concentration of residual
chlorine in the discharged
cooling water should not
exceed 0.05 mg/L. Industries
in Qatar find it difficult
to meet these new standards.
-
Therefore, both regulators
and industries in Qatar are
looking for ways to minimise
environmental pollution
while achieving high
performance of the cooling
system with reasonable cost.
