Environment
Background
The quality of our local living environment has a direct impact on our health. Protecting our natural surroundings therefore remains a long-term priority for both our generation and those to come. Each country in the OECD has their own unique environmental concerns, due to differences in consumption, pollution, climate, industry and trade. However, countries also need to work together as certain environmental problems, like air pollution and ozone destruction, do not respect national borders and can have a spill over effect.
Air Pollution
Outdoor air pollution is one important environmental issue that directly affects the quality of peoples’ lives. Air pollution in urban centres, often caused by transport and the use of small-scale burning of wood or coal, is linked to a range of health problems, from minor eye irritation to upper respiratory symptoms in the short-term and chronic respiratory diseases such as asthma, cardiovascular diseases and lung cancer in the long-term. Some of these complications require hospital treatment, and may be fatal. Children and the elderly may be particularly vulnerable.
PM10 – tiny particulate matter small enough to be inhaled into the deepest part of the lung – is monitored in OECD countries because it can harm human health and reduce life expectancy. In the last two decades, PM10 concentrations have significantly decreased in many OECD countries, yet at 22 micrograms per cubic meter on average, they are still above the annual guideline limit of 20 micrograms per cubic meter set by the World Health Organisation. For the year 2000, exposure to PM10 caused approximately 960 000 premature deaths.
Despite national and international interventions and decreases in major pollutant emissions, the health impacts of air pollution are not likely to decrease in the years ahead, unless appropriate action is taken.
