Air is common good and a
gift to humanity. Amongst Philippine Environmental Laws, RA No. 8749
– Philippine Clean Air Act of 1999 had marked best for me, as it
recognizes the right of every individual to breathe clean air, to
utilize and enjoy all natural resources according to principle of
sustainable development. However, this so called best environmental
law of the land is yet implemented ineffectively. Based on 2005
report of the World Health Organization (WHO), Metro Manila ranks
among the urban areas in the world with most polluted air – next
only to Mexico City, Shanghai, and New Delhi. Metro Manila, the
country’s National Capital Region (NCR), has been climbing the air
pollution charts for the few years previous to 2005.
Clean air essential to
good health. Unfortunately, toxic air pollutants and contaminants
affect the air we breathe. Based on studies, about 80 percent of
polluted air in the country comes from mobile sources such buses,
cars and jeepneys. The other 20 percent is emitted by industrial
sources such as power plants and factories and are sources such as
open burning of garbage, smoking and construction activities.
Senate Bill 234, also
called the “Accelerated Retirement of Inefficient Vehicle Act”
authored by Senator Mirriam Defensor Santiago, encourages the
establishment of a five-year program of replacing old and
fuel-inefficient vehicles for more fuel-saving models. This was
supported by the Department of Environment and Natural Resources to
reduce air-pollution and improve air quality. Countries including
Singapore have such program in place, but incentives needed to make
the program a success can be costly. In supporting legislation to
phase out old vehicles, the DENR should make sure the country has
sufficient resources for such incentives.
Clean Air Act was created
year 1999, if only it was enforced and monitored accordingly, we need
not Senate Bill 234 and Philippines will not be labeled as “Most
Polluted Air in the World.” According to an editorial in Philippine
Star (July 1, 2011), the popularity of the Light Rail and Metro
Railway Transit in Metro Manila show that people want quick,
efficient and relatively safe mass transportation. But the MRT and
LRT cannot adequately cope with passenger volume particularly during
peak hours. So people continue to use private vehicles, investing in
old cars especially for their children’s use, and for days when
their old cars are banned under the number coding scheme in Metro
Manila.
I see efforts from
DENR-EMB in terms of awareness programs through campaign in
partnership with Philippine Medical Association (PMA), the Kapisanan
ng Broadkaster ng Pilipinas (KBP) and other government agencies and
local government units through Memorandum of Agreement signed
December 9, 2011, to strengthen the implementation of the program to
reduce air pollution from motor vehicular sources. PMA and KBP
committed to help raise public awareness on the urgency of addressing
the country’s worsening air pollution problem; emission testing
(particular in EDSA where buses are randomly checked) that requires
vehicle to undergo regular maintenance check. But, majority of public
transportation owners (jeenpneys and buses) scrimp on expenses, thus,
opted sending their vehicles to services in case of breakdown only.
Also, there are municipalities that bans smoking in public and used
of social media in reporting smoke belchers. Quoting Jim Stewart
(Canadian CEO) “the first law of successful implementation is that
70% of something is better than 100% of nothing.”
Major Air Pollutants
Monitored by Clean Air Act
Carbon Monoxide (CO)
– It is an odorless and colorless gas produced by the incomplete
burning of carbon-based fuels, including gasoline, oil and wood. It
can also build up in high concentrations in enclosed areas such as
garages and along roadsides during heavy traffic.
Ozone (O3)
– It is a gas that is variety of Oxygen. Ozone in the upper
atmosphere is known as the ozone layer which shields the Earth from
sun’s dangerous ultraviolet rays. However, at ground level it is
considered a pollutant with highly toxic effects. Some of the major
sources of ground-level ozone are vehicles and industries. Some of
the ill effects of this pollutant include irritations in the
respiratory tract, chest pain, persistent cough and an increased
susceptibility to lung infection.
Nitrogen Oxide (NOx)
– Nitrogen oxides are produced from burning fuels, gasoline and
coal. It is a major contributor to smog and acid rain. In high doses,
smog can harm humans especially asthmatics and can cause general
illness of the respiratory system. Acid rain, on the other hand, can
harm vegetation and change the chemistry of the water thus affecting
marine life.
Particulate Matter
– It is any type of solid particles in the air in the form of
smoke, dust and vapors. Particulate Matter is produced by many
sources, including burning of diesel fuels by vehicles, fossil fuels,
mixing and application of fertilizers and pesticides, road
construction, industrial processes and operation of woodstoves. Some
microscopic particles in the air can be breathed into the lungs
causing increased respiratory disease and lung damage.
Sulfur Dioxide (SO2) –
It is an odorless gas at low concentrations, but can have a very
strong smell at high concentrations. Sulfur Dioxide is a gas produced
by burning coal, most notably in power plants. Some industrial
processes, such as production of paper and smelting of metals,
produce sulfur dioxide. It can harm vegetation and metals and can
cause lung problems, including breathing problems and permanent
damage to lungs.
Volatile Organic
Compound (VOCs) – These are organic chemicals that are found in
gasoline, industrial chemicals such as benzene, solvents such as
toluene and xylene, and perchloroethylene (principal dry cleaning
solvent). Vehicle emissions are an important source of VOCs. These
chemicals are released from burning fuel, such as gasoline, wood,
coal, and from solvents, such as paints, glues, and other products
used at home or work.
