Seoul has sent aircraft over the Yellow Sea to carry out cloud-seeding experiments in a bid to tackle air pollution
Seoul on Friday sent aircraft over the Yellow Sea to carry out cloud-seeding experiments in an effort to tackle air pollution many South Koreans blame on China.
Beijing has been seeking 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 Organisation norms, and pollution levels in Korea sometimes spike as the prevailing winds blow PM2.
