Abstract :

Particles in fine dust have the first rank of carcinogens, making their study necessary. The previous results showed that particles with aerodynamic diameters of 2.5 and 10 micrometers are more permeable and pass through respiratory filters and are the main cause of damage. In this study, the effect of fine particulate matters in different cities of Khuzestan province of Iran on blood cells of male rats was compared. Thirty adult male rats were divided into six equal groups, including control, Ahvaz, Ramhormoz, Andimeshk, Abadan, and Susangerd and were treated for two months. The results of blood cell analysis showed an increase in the number of white blood cells, especially lymphocytes in Ahvaz group, while the volume of platelets was significantly reduced. In most groups, a significant decrease was observed in RDW and the amount of hematocrit in Ramhormoz and Susangerd groups showed a significant increase compared to the control group. Therefore, given the different heavy metals composition, fine dusts have different effects on blood parameters, depending on their amount and duration of exposure.
