S. Korea's first airborne fight against 'Chinese' pollution fails

South Koreans frequently don breathing masks to combat poor air quality

An attempt by South Korea to create artificial rain to tackle air pollution many blame on neighbouring China has failed, the government said Monday, as it struggles to address what has become an urgent public concern.

Many South Koreans blamed China when pollution surged for three days earlier this month, and on Friday the Korea Meterological Administration (KMA) sent an aircraft to seed clouds with silver iodide in the hope of promoting rain.

The intention was for the rain to douse and pollutants known as "fine dust" in South Korea.

However, an initial analysis of the experiment has been disappointing, KMA said in a preliminary report issued Monday.

While a weak, misty rain was detected for several minutes, the agency said, "there was no observation of significant precipitation".

"Aside from its success or failure, the test was an opportunity to accumulate the necessary technology for a faster commercialisation of cloud seeding," it added.

A full report is expected to be released later next month.

Air quality in South Korea is generally better than in China, which is more frequently affected by choking bouts of filthy air.

South Korean President Moon Jae-in last week advised his officials to handle the issue as a "natural disaster" as he urged cooperation with Beijing, addressing "great public concerns about fine dust coming from China".

Beijing is also trying to tackle the scourge, which causes widespread public anger, and a recent study found urban levels of PM2.5—the tiny airborne particles considered most harmful to health—had been cut by almost a third on average over four years.

But they remain far above World Health Organization norms, and pollution levels in Korea sometimes spike as the prevailing winds blow PM2.5 particulates across the sea between the two countries.

China, which according to the International Energy Agency uses coal to generate around three quarters of its energy, is regarded as the world's biggest polluter.

Last year, South Korea shut down five ageing coal-fired in a bid to improve its air quality.
