Sistan in east Iran is vast, lowland of which a great portion is consisted of alluvial-saline lands of dried out Hamoon lakes. Sistan has the highest population density in eastern Iran. This population is distributed in more than 1000 cities, villages and nomadic settlements. Sistan plain is extensively exposed to vigorous winds. 120-days wind is the most significant wind in the region which starts every year at the end of the spring and lasts all through the beginning of autumn, with a mean velocity of 100 km/h. This research utilizes a survey/descriptive method coupled with medical documents to rank the risk of destructive wind sediment dispersion in different regions of Sistan alongside the frequency of citizen’s reference to medical centers due to respiratory problems or eye damages caused by these sediments during the summer of 2017. Wind sediment distribution in the environment, threatens the health of citizens. Human ecosystems in the Sistan region show a different ranking of the risks of dust on the health of the respiratory system and the eyes of citizens exposed to these materials. The citizens of these areas traditionally protect the health of their eyes and their breathing apparatus when dispersing wind deposits, using shawl cloths and his hand. As the last resort, they migrate from their homes and empty their habitats.
