YELLOW SAND
Northern China and Mongolia are the origins of Yellow Sand during
springtime. Yellow Sand is known to contain high concentrations of sand,
heavy metals, and harmful gases. During this season, the dust
concentration severely increases in Korea, China, and Japan, leading to
higher occurrences of health problems such as rhinitis. |
