[Weekender] Korea more vulnerable to air pollution

A latest report from the Organization for Economic Cooperation and Development has sent a solemn message to the world: If we do not effectively tackle air pollution, it could cause 6 to 9 million premature deaths and economic consequences of $2.6 trillion annually by 2060.

South Korea was among countries singled out as those in greater danger. The report said that South Korea could see at least 1,109 early deaths per 1 million people in 2060 -- the only OECD member to exceed the 1,000 mark -- unless the country makes significant efforts to prevent air pollution.

The premature death rate for Australia and New Zealand for the same year was projected to be only 95 early deaths per 1 million people, just 8.6 percent of South Korea’s figure. 

Other than South Korea, India and China was also predicted to see the biggest rises in mortality rates from air pollution, due to rising populations and exposure to emissions from factories and traffic.

The report also highlighted that increasing health costs and decreasing labor productivity will have the biggest impact on gross domestic product loss. Countries like China, Russia, India and Korea will be hit hardest by GDP losses, it added.

Between 2001 and 2006, the concentration of coarse particulate matters (PM10) were 51 to 61 micrograms per cubic meter in Seoul. With the implementation of the air environment management plans for the metropolitan region since 2005, the concentration dropped to below 60 micrograms per cubic meter and further to 40 micrograms per cubic meter in 2014.

Air has improved at a stagnant pace since then, with air quality remaining poor compared to other advanced nations. 

Experts say that the high density of fine dust in South Korea derives from its high population density and rapid industrialization, as well as the impact of geographical proximity with China. Major domestic culprits include emissions from vehicles and coal-fired power plants.

Other causes also come from the meteorological characteristics of the country, such as precipitation being concentrated during summer, making it harder for fine dust to be washed out. Frequent formation of high atmospheric pressure also leads to air stagnation. 

Last May, when the OECD unveiled the 2016 Better Life Index, South Korea ranked last out of 38 OECD member countries. According to the report, South Korea’s average level of ultrafine dust particle concentration was at 29.1 micrograms per cubic meter, double the OECD average of 14.05 micrograms per cubic meter and triple the World Health Organization’s recommended level at 10 micrograms per cubic meter. 

“The number of lives cut short by air pollution is already terrible and the potential rise in the next few decades is terrifying,” said OECD Environment Director Simon Upton in the latest report.

“If this is not motivation enough to act, this report shows there will also be a heavy economic cost to not taking action. We must prevent these projections from becoming reality,” he added.
