Dust from Mongolia’s Gobi Desert has begun arriving in South Korea, beginning the country’s annual yellow dust season. The dust from Mongolia, as well as China’s deserts, arrive in South Korea each year from February through June.
The dust, carrying heavy metals, causes health concerns for children under age 11, seniors over age 65 and people with heart and breathing conditions. According to officials, levels above 800 micrograms per cubic meter of air call for a warning to the community. Isolated areas in South Korea have already reached over 1000 micrograms per cubic meter of air.
At levels between 400 and 799, high-risk individuals should not participate in outdoor activity and others should avoid physical training and strenuous outdoor labor.
Further, some South Korean high tech manufacturing can be impaired by yellow dust.
