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.
