5. Environmental Challenges
5.1 Outdoor air quality
Many people are exposed to
health-threatening air pollution, especially in large cities. The
steering instruments available to reduce local air pollution
problems are spread over many different authorities and
administrative levels, and are not co-ordinated well enough. Closer
co-operation among these authorities is needed in the areas of data
collection and reporting, research and instruments. A total review
and assessment of instruments has already begun.
Existing national goals
The Ministry of Environment has
formulated the following strategic goals and target goals for air
pollution (Parliamentary Proposition nr. 1, 1997-98):
Strategic goal:
Air pollution and noise problems
shall be prevented and reduced such that peoples' health and well
being are protected.
Target goals:
By the year 2005, the daily average
concentration of dust (PM
10) shall not exceed 50 µg/m
3> more than 25 days per year. By year 2010, this
limit shall not be exceeded more than 7 days per year.
By year 2010, the hourly average
concentration of nitrogen dioxide (NO
2 ) shall not exceed 150 µg/m
3 >more than 8 hours per year.
By year 2005, the daily average
concentration of sulphur dioxide (SO
2) shall not exceed 90 µg/m
3>.
By year 2010, the background
concentration of benzene in city air shall not exceed 2 µg/m
3>, calculated as an annual average
concentration.
5.2 Indoor climate
Goals and instruments for indoor
climate have been formulated on the premise that asthma, allergy
and illness related to indoor climate constitute a major health
problem. As a group they are one of our most important common
health problems, and cause significant suffering, chronic illness
and resource use.
Relevant instruments for preventive
work with asthma, allergy and illness related to indoor climate are
found primarily in the health sector, but also within other
sectors' areas of responsibility. It is thus critical to co-operate
across sectors. On this background, an interdepartmental action
plan has been developed to prevent asthma, allergy and illness
related to indoor climate.
Like other chronic diseases, asthma
and allergy are the result of an interaction between genetic and
environmental factors. Because of the central role played by the
environmental factors, the potential for prevention is large. This
assumes, however, that risk factors can be identified and that
enough knowledge exists about how these can be reduced or
eliminated.
It is important to note, however,
that much is still unknown in this field, including the most
important risk factors are and the most susceptible age groups.
Internationally there is a great deal of research and discussion.
We can therefore expect that more knowledge will become available
in the coming years that will give a basis for reorienting
prevention efforts. The goals for targets and instruments must be
based on today's knowledge. Although we lack new knowledge about
asthma, allergy and diseases related to indoor climate, we do have
adequate knowledge in a number of areas about what increases the
risk of developing susceptibility to these illnesses and to trigger
their symptoms.
Existing national goals
National goals were set by
Parliament in connection with Report to the Norwegian Parliament 37
(1992-93), Challenges in health promotion and prevention efforts:
(unofficial translation)
"By the year 2002, co-ordinated
planning and actions to reduce health-threatening indoor climate
shall, together with health-promoting behaviour and knowledge and
early intervention in the course of the disease, stop the increase
in asthma and allergy among children under 7 years of age, and
reduce illness and improve functioning in all age groups."
Operative goals
Based on this overall goal, eight
main operative goals were further specified in the Action Plan for
prevention of asthma, allergy and indoor climate illnesses:
- Increased knowledge in the population about central risk
factors.
- Indoor environments as free of allergens as possible in
kindergartens and schools.
- Reduced exposure to health-threatening factors in the indoor
environment.
- Reduced outdoor air pollution from various sources.
- Better co-ordination of registration and diagnostics
procedures.
- Increased research-based knowledge about disease incidence,
causes, risk factors and mechanisms.
- Greater opportunities to avoid substances and products which
are not tolerated.
- Increased knowledge among those who suffer from asthma and
allergy about how illness can be reduced and ability to function
improved.
These goals include asthma and
allergy related to other conditions than indoor climate, but most
of them are also relevant to the issue of indoor climate.
The following is an overview of
actions and instruments with corresponding target goals, taken from
the Action Plan for prevention of asthma, allergy and indoor
climate illnesses. Only actions related to the Ministry of Health
and Social Affairs and the Ministry of Environment are included
here.
Target goal 1
The population shall be informed
about what actions should be taken to improve the indoor climate in
private homes, especially as related to humidity, carpets and
pets.
Target goal 2
Schools and kindergartens shall be
planned and run such that asthma, allergy and illness related to
indoor climate are prevented.
Target goal 3
By Dec. 31, 1999, schools and
kindergartens shall be able to document that the indoor climate
conforms with regulations.
Target goal 4
The competence of kindergarten and
school personnel about conditions at each workplace relevant to
indoor climate, shall be increased.
Target goal 5
Municipalities and relevant
professional institutions shall be familiar with new standards for
indoor air quality.
Target goal 6
The proportion of the population
exposed to involuntary passive smoking shall be reduced.
Target goal 7
All expectant parents and parents
of babies and small children shall be aware that passive smoking
can increase the risk that children will develop respiratory
diseases and may cause a worsening of existing illness.
Target goal 8
Increased knowledge about:
- The importance of indoor climate for development of asthma and
allergy, and better baseline data on incidence of these
illnesses.
- The effect of measures taken, in terms of both health and
economics.
- Effective intervening actions in prevention work.
5.3 Noise
Many people suffer from exposure to
noise. The noise originates from many different sources and comes
under the jurisdiction of many different authorities and
administrative levels. A detailed review is needed of the
instruments available, to clarify how they can be used more
effectively and co-ordinated among the various central, regional
and local authorities. To obtain the best possible information base
for decision-making, more research and monitoring are also
needed.
Existing national goals
The Ministry of Environment set up
the following strategic goals and target goals for noise in
Parliamentary Proposition 1 (1997-98):
Strategic goals
Air pollution and noise problems
shall be prevented and reduced such that peoples' health and
well-being are protected.
Target goals
Significantly improved air quality
in cities and towns by the year 2005 compared to 1994.
A detailed review of goals and
actions is planned for 1999. Operative goals for noise have
therefore not yet been formulated.
5.4 Water quality
Existing regulations and guidelines
describe how illness due to contagions and other health problems
shall be prevented, both for drinking water supplies and for
natural and swimming pool bathing water. Many facilities don't
fulfil the requirements in the regulations. To promote compliance
with the regulations, the government has a "Program for water
supply" which can give economic support to improve water plants
that don't satisfy the requirements. It has been decided that this
program will be continued. In addition, a better overview of the
status of small, unregistered water supply facilities is
needed.
Existing national goals
When establishing the "Program for
water supply" in 1995, the government set the following goal:
(unofficial translation)
Water plants that deliver water to
the general population or to the food industry, shall deliver
adequate amounts of water having quality which is hygienically
satisfactory and acceptable to users.
In Parliamentary Proposition 1
(1998-89), the Ministry of Environment set the following goal:
In fresh waters and marine regions,
a water quality shall be ensured which maintains species diversity
and ecosystem function, and which protects the health and
well-being of people. This means that the water quality in terms of
nutrients, particles, organic material and oil shall satisfy user-
and/or environmental protection interests related to fresh water,
fjords and marine areas.
Operative goal 1
Water plants that deliver water to
the general population or to the food industry, shall deliver
adequate amounts of water having quality which is hygienically
satisfactory and acceptable to users.
Operative goal 2
All drinking water supplied to
households and the food industry from small, unregistered water
supplies shall be hygienically satisfactory.
5.5 Food contaminants
Most of the issues related to food
contaminants have been regulated for many years, and there are no
data suggesting that food contaminants have direct effects on
health in Norway. To maintain this preventive approach, it is
important to continue monitoring and mapping activities. More
knowledge is needed about intake/exposure in susceptible groups
such as children, the elderly, patients and groups that consume
large amounts of particular foods.
Oversensitivity reactions due to
contaminants should be investigated more closely. Studies are
needed on body doses/levels of contaminants in blood, urine and
milk, especially for environmental toxins (heavy metals,
chlororganic compounds and toxins from moulds).
Increased international trade in
foodstuffs and increasing amounts of travel present a challenge to
today's systems in terms of preventing disease due to contagions.
There is a need to develop and improve systems for mapping and
monitoring pathogenic organisms in food and drinking water,
including more effective use of the data.
Contagions found in foodstuffs and
bacteria that are part of the natural microflora of the foodstuff
can be naturally resistant or can develop resistance to
antibiotics. There is also reason to focus on possibly transferable
genes for resistance in bacteria used to produce various fermented
products (including cheese, yoghurt and dried sausages).
Existing goals
Foodstuffs offered to the public
shall be safe for health.
Operative goal 1
Reduced exposure to food additives
in situations where the approved daily limits for intake may be
exceeded.
Operative goal 2
The presence of pesticides in foods
shall be reduced as much as possible and shall not exceed the
approved limits.
Operative goal 3
Reduced unintentional exposure to
allergens in foodstuffs.
Operative goal 4
Reduced risk that microbes in food
develop resistance to antibiotics, and reduced the risk that
resistant microbes are transferred from food to humans.
Operative goal 5
Incidence of environmental toxins
(metals, halogenated organic compounds) in foods shall be reduced
as much as possible and intake shall not exceed tolerated
amounts.
Operative goal 6
Reduced exposure to contaminants
produced by industrial processes (heterocyclic amines, PAH).
Operative goal 7
Food packaging shall not present a
threat to health.
Operative goal 8
The National Institute of Public
Health and the Norwegian Food Control Authority shall have better
knowledge about the impact of natural toxins on health.
Operative goal 9
Foods shall not contain
disease-causing micro-organisms.
Operative goal 10
Genetically modified food shall not
constitute a threat to health.
Operative goal 11
The causes of food-borne infections
shall be identified and eliminated.
5.6 Chemicals threatening to health and
environment
Chemicals make everyday life
easier, but at the same time they carry a threat of serious effects
on the environment and people's health, both at the workplace and
in private life. The level of protection in Norway is nevertheless
high, compared to other countries. Through the Agreement for the
European Economic Area, Norway has full rights and obligations in
the great majority of issues related to chemicals, and this ensures
harmonised legislation. Few instruments other than juridical
regulation have been used. Several new approaches are about to be
put into practice, such as required substitution, more concrete
criteria for undesirable properties, and lists of undesirable
chemicals. An overall strategy for utilizing information about
chemicals and health should be developed co-operatively by the
health-, environmental- and consumer authorities.
Knowledge about the potential
health effects of chemical substances is inadequate: for example,
the effect of long-term low dose exposure, interaction among
chemicals, and types of exposure conditions that are unique for
Norway. The number of new professional personnel who can provide
the authorities with knowledge about these issues should be
significantly improved.
Monitoring of the concentration of
chemicals in the environment and developing effective indicators
that link exposure and health effects should be a priority area in
the future, and co-operation between the relevant authorities must
be formalised. Supervision and controls are an example of
established co-operation that functions well.
Existing national goals
Discharge and use of chemicals
dangerous to health and the environment shall not cause damage to
health or to nature's ability to produce and renew itself.
Concentrations of the most dangerous chemicals in the environment
shall be reduced to near background levels for naturally occurring
substances, and to near zero for anthropogenic compounds
(Parliamentary Proposition 1, 1997-98, Ministry of
Environment).
Existing target goals
Discharge of specific environmental
toxins (see the priority list in Report to the Norwegian Parliament
nr. 58 (1996-97) and Parliamentary Proposition 1 (1997-98)) shall
be stopped or significantly reduced by year 2000, 2005 and
2010.
Discharge and use of chemicals
dangerous to health and the environment shall be continually
reduced, with the goal of stopping the discharges within one
generation (25 years).
The risk that discharge and use of
chemicals will cause damage to health and the environment shall be
significantly reduced.
Operative goal 1
The degree of protection of health
and environment against damage by chemicals shall be continually
improved.
Operative goal 2
Knowledge about the effects that
exposure to chemicals dangerous to health and the environment have
on health shall be significantly improved, with emphasis on
exposure from diffuse sources and the ambient environment.
Operative goal 3
Better flow of and access to
information about chemicals dangerous to health and the
environment, to all kinds of users.
5.7 Injuries
The most important efforts to
prevent injuries take place in municipalities and local
communities. The efforts are organised as a co-operation among many
actors, in which the public sector, volunteer and private
organisations and citizens themselves participate. Municipal-based
developmental work is therefore emphasised in the follow-up to the
interministerial action plan, and is further ensured through the
target goals and actions of "Safe communities." Experience has
shown that immediacy and a feeling of responsibility for the
challenges and tasks is important, and that preventive actions
based on local injury statistics and high-risk conditions give
measurable results.
Important tasks at the national
level are, in addition to influencing framework factors such as
laws, regulations and budgets, to contribute to increased knowledge
and competence in the field through research and development work.
Further, the national authorities use information, communication
and network-building as instruments to ensure that the
municipalities have access to knowledge and use this knowledge in
their practical implementation work.
The National Institute for Public
Health has an important function as supporting partner for the
ministries' work to follow up the action plan. One important role
is to stimulate the municipal sector to work for accident
prevention, including responsibility for advisement, statistics on
accidents and injuries and secretariat functions for "Safe local
communities."
Existing national goals
The national goals for this field
were set by Parliament in connection with Report to the Parliament
nr. 37 (1992-93) Challenges in health promotion and preventive
efforts: (unofficial translation)
By the year 2000, co-ordinated
planning and development of a culture of safety at all levels of
decision-making and in all sectors shall lead to a reduction in the
number of injuries causing death, hospital admissions and medical
treatment due to accidents.
Operative goals
The following main goals were set
for this area in the interministerial Action Plan 1997-2002:
Prevention of injury at homes, school and recreation:
- 25% reduction in death due to injuries from 1980 to year
2000.
- Injuries leading to hospital admission and medical treatment
shall be reduced by at least 10% from 1993 to 2002.
Actions and instruments are taken
from the Action plan for prevention of injury at homes, school and
recreation. The target goals and actions/instruments are divided
into various arenas for accidents: prevention of injuries in homes
(including residences and residential areas, service homes for the
elderly, nursing homes and fires in residences) prevention of
injuries at school, kindergarten and playgrounds, prevention of
recreational, sea-, lake and water injuries, prevention of sports
injuries and prevention of injuries on streets, highways and
railroads (not including traffic accidents). We present here the
target goals and instruments which involve the Ministry of
Environment and/or the Ministry of Health and Social Affairs.
Target goal 1
Improved knowledge about the
factors contributing to injuries in residences, service homes and
nursing homes.
Target goal 2
The elderly shall become familiar
with how the most common home injuries among the elderly can be
prevented.
Target goal 3
Municipal employees, others who
work with elderly living at home, personnel who work with children
and youths, and parents shall increase their competence in
prevention of injuries, including risks of injury and actions to
prevent specific kinds of injuries.
Target goal 4
In their zoning plans,
municipalities shall set aside and secure areas and facilities in
the local environment to be used by children and youths and ensure
that kindergartens, playgrounds and schools are located and
constructed such that they are safe from pollution, noise, traffic
dangers and other threats to health.
Target goal 5
Schools and kindergartens shall
have an internal control system which ensures health, environment
and safety.
Target goal 6
Activity programmes offered to
children and youths, including physical education at school, shall
contribute to body awareness and control as a deterrent to
injuries.
Target goal 7
The number of rescue operations
caused by lack of knowledge about safety in unorganised outdoor
recreation, shall be reduced.
Target goal 8
Sports leaders and participants
should have knowledge about how sports injuries can be
prevented.
Target goal 9
A co-ordinated and improved system
for national and local sports statistics.
Target goal 10
Increased research-based knowledge
about the effect of instruments.
Target goal 11
Co-ordinated information and
efforts to strengthen and stimulate local work to prevent
injuries.
Target goal 12
Networks and meeting places for
learning, communication of information and knowledge, and transfer
of experiences to strengthen and promote local injury prevention
work.
5.8 Radiation
The greatest health problems in
connection with radiation are related to radon in indoor air, radon
in water and ultraviolet radiation. Radon is especially dangerous
in combination with smoking.
An estimated 150,000 residences
have a radon concentration in indoor air which exceeds the
recommended level for remedial actions, 200 Bq/m
3>. Similarly, an estimated 20,000 households have a
water supply which exceeds the recommended level for remedial
actions, 500 Bq/l. It is important to identify the residences and
ground water sources that have values exceeding the recommended
level through focused surveys and mapping. Reducing the radon
concentration in both indoor air and household water often involves
simple and inexpensive actions.
According to the municipal health
care act and the Plan- and Building Act, among others,
municipalities play an important role in monitoring and informing
the public about the existing situation locally, both in terms of
remedial actions in existing buildings and requirements for
constructing new buildings.
Regarding ultraviolet radiation,
the municipalities have an important role in informing the public
about protection from the sun and the damaging effects of excessive
sun exposure. Further, municipalities are responsible for
supervision of solaria. The municipality should be able to provide
general information about low frequency and high frequency
fields.
Operative goal 1
Change peoples' behaviour when
sunning, through better knowledge about effects, health risks and
prevention.
Operative goal 2
Municipalities shall have the
competence needed for effective supervision of solaria.
Operative goal 3
The municipalities will become
enabled to do their own assessments/supervision of sources of radio
frequency and extreme low frequency fields.
Operative goal 4
Affected households shall be
familiar with measures that can be taken to reduce the flow of
radon from the ground. Radon level of all kindergartens in the
country shall be measured.
Operative goal 5
Where remedial actions are or could
be needed, geographic regions and food products shall be
surveyed.
Operative goal 6
The concentrations of radioactive
contamination in foods shall be monitored to be able to calculate
radiation doses reaching the population, document the situation and
make prognoses for trends over time.
Operative goal 7
The dose of radiation exposure due
to radioactive contamination of foods shall be limited by
monitoring and using allowable limits and feeding treatments before
slaughter to reduce the radioactivity level.
5.9 Outdoor recreation
The main challenge for outdoor
recreation work in the future is to ensure that all citizen have
easy access to nature and recreational areas where they live. This
pertains especially to the urban population and to children and
youths. The health authorities must be ensured adequate capacity
and competence to be able to become much more involved than at
present in central issues about area use that have great
significance for peoples' health and well-being.
Next, it is necessary to make
active and sustained efforts to promote physical activity in
natural surroundings and thus counteract the tendency toward
sedentary indoor activities. Here a co-operation among sectors at
all levels is important, and especially co-operation between the
authorities and non-government organisations.
Local Agenda 21 processes in
municipalities will be important arenas for developing networks and
co-operation. It is important that both the health- and
environmental authorities locally exploit this common opportunity
to create popular participation in preventive health and health
promotion work.
Operative goal 1
The health- and environmental
authorities shall, together and individually, contribute to
integration of outdoor recreation as a health policy instrument in
all county plans and one-fourth of municipal plans by the end of
the next plan period (year 2003).
Operative goal 2
By the end of year 2000, the health
authorities and environmental authorities shall together contribute
to documentation of the areal qualities/resources and environmental
qualities of residences, schools and kindergartens in the ten
largest cities. The documentation will be completed within a
10-year period for other municipalities containing cities and
towns.
Operative goal 3
By the year 2001, the health- and
environmental authorities shall, together and individually,
contribute to at least 10% of Norway's municipalities having
started projects related to green structure by the year 2001.
Operative goal 4
The health authorities and the
environmental authorities shall, together and individually, make
efforts to see that outdoor recreation becomes an integral part of
activities at schools and kindergartens, which is widely used in
preventive and health-promotion work in municipalities.
Operative goal 5
By the end of 1999, the
environmental and health authorities shall compile research-based
knowledge about outdoor recreation and health.
5.10 Qualities of place – cultural environment and
architecture
There is a need to:
- improve knowledge about the relationships between
health/quality of life and cultural environment in our physical
environment;
- collect and systematise relevant knowledge based on experience
and results of investigations;
- strengthen the contact between professional groups working with
health and development of place;
- establish an interdisciplinary research and development effort
in this field, for example through a separate research programme
under the Norwegian Research Council;
- build professional competence to work with these topics within
municipal and county planning departments; and
- establish permanent fora (or routines), both centrally and
locally, for contact and co-operation between the authorities
responsible for health and qualities of place.
Operative goal 1
Cultural history qualities shall be
integrated into regional and municipal plans.
Operative goal 2
Knowledge about the importance of
cultural heritage/cultural environments for health, well-being and
quality of life, and as an element of preventive health work, shall
be improved.
Operative goal 3
Access to, and distribution of,
information about qualities of place shall be improved at all user
levels.
