Dust particles, which now contain oxides such as aluminium, calcium, iron, magnesium, potassium and silicon, can adsorb on your eye and cause conjunctivitis and xerophthalmia.
As yellow dust enters the respiratory tract, it irritates the membranes, leading to various diseases. Also, the elderly, children, and patients with respiratory conditions can suffer from more severe sympotms.
Because yellow dust particles are very small, they can enter deeply into your skin through pores and cause troubles like acne, and worsen atopy. They cause more severe symptoms on high temperatures with sweat and sebum.
