This investigation has been conducted to study some properties of local storm dust phenomena in Baghdad city. The monthly average of dust (g/m²)  in Baghdad  range from 10.2 g/m²  in Nov. to 43.7 g/m² in April. The local dust has a high Aerobic bacteria total count (Abtc) and O.M (% ) compare to the storm dust. This may be due to the contamination of dust particularly the local dust. The correlation  coefficients between Abtc (No./100ml) Organic Matter (O.M)%  and EC mmhos/cm, PH, Ca%,  Mg%, Na meq/100g, Na meq/100 g, K meq/100 g and dust, g/m²  have been done. The results indicate high relationships between Abtc ( No./ 100ml) Organic matter (O.M)%. The local dust (x) has high relationships with Abtc and O.M (% ) as examples. These  have the follow Equation s: 1. O.M. % = 3.805 - 0.054 X, r =   0.9534,  describe the relation between O.M %  and the studied local dust(x). 2. Abtc  NO.  = -8.725E2 + 56.623 X, r =   0.7733, describe the relation between  Abtc  NO.  and the studied local dust(x). The local  dust  samples are more contaminated compare to the storm dust  samples in the city.
