Developed
by the Magallanes Health Services and the University of Magallanes,
the program - "Magallanes Ozone 2000" - instructs citizens
to minimize their exposure to the sun by wearing wide-brimmed
hats, long pants and long sleeved shirts, and religiously apply
sun screen on a daily basis.
The
program includes a rating system which indicates the degree
of ultraviolet radiation danger by yellow, orange and red alerts,
and will go into full effect in mid-October.
"Since
the beginning of September, we have seen a worrisome decrease
in the level of ozone to around 220 Dobson Units," Claudio
Casiccia, head of the Ultraviolet Radiation Monitoring Laboratory
at the University of Magallanes says. "This is a situation
that emerged at the end of the 1970s and is worsening every
year." Magallanes Ozone 2000 declared the first yellow alert
of the year Sept. 19 when ultraviolet radiation levels surpassed
a rating of 4.4.
According
to Hernan Olivares, an environmental engineer and director
of Magallanes Ozone 2000, the goal of the rating system is
to alert and protect citizens when ultraviolet radiation reaches
potentially dangerous levels.
Known
health problems stemming from exposure to UV light include
varying degrees of sunburn, vision problems and the long-term
risk of skin cancer.
"The
recommendations to the public are being transmitted through
a media campaign that includes advertisements and announcements
on regional television, radios and newspapers alerting the
public one day in advance when a warning will be in effect," Olivares
said.
The
environmental expert added that the most dangerous times of
day are from around noon until 3 p.m.
In
addition to the use of protective hats and clothing, the Magallanes
Ozone 2000 campaign recommends using sunglasses with UV filters
and maximum-protection sun block. Olivares said people with
lighter complexions face a higher risk of skin damage.
Other
program recommendations include keeping infants entirely out
of the sun until six months of age. Older babies and children
should only go in the sun for short periods of time and always
with plenty of sunscreen.
According
to Jorge Flies, Director of Health Services in Magallanes,
the campaign was designed to present clear and simple messages
about the dangers of UV exposure. In contrast to the technical
criteria used to determine UV danger on any given day, which
is highly complex and difficult for a layperson to understand,
the Magallanes Ozone 2000 project offers citizens a straightforward
way to assess the health risks and take appropriate precautionary
measures.
According
to Flies, the yellow alert does not include suspending school
classes but does mean that sports practices and other activities
cannot be held out of doors. He emphasized that the dangers
of ultraviolet exposure are equally serious on sunny and cloudy
days.
Notwithstanding
the precautions recommended by Magallanes Ozone 2000, experts
are predicting an increase in the incidence of skin cancer
over the next five years.
Jaime
Abarca, the only practicing dermatologist in Magallanes, says
he has seen a steady increase in cases of moderate to severe
sunburn over the last several years. Abarca added that the
majority of Magallanes residents are fair skinned and hence
more susceptible to severe burns and skin cancer.
Notwithstanding
the obvious health risks, Olivares says he does not expect
residents to begin taking the recommendations seriously for
another year.
"For
that reason, we will begin conducting informational workshops
in high schools, preschools and neighborhood associations,
so that the public knows what we are talking about and what
measures they should take when we announce a yellow or red
alert," he said.
NASA
predicts the ozone hole will continue to grow throughout the
late spring and early summer, reaching its peak in three to
four weeks.
