Metal concentration of atmospheric inhalable particles in Jedda

Presents the measured concentrations of iron, zinc, cobalt,chromium, nickel, lead, manganese and sodium in atmospheric inhalable coarse and fine particles for the period September 1984‐April 1986 in Jedda, Saudi Arabia. The results show that iron and sodium have the highest concentrations, indicating that inhalable particles are of soil and sea origin. The metal concentrations of fine inhalable particles are much smaller than those of coarse inhalable particles, so that human health is hardly affected.
