Abstract : Street dust collected from three different sites in greater Cairo was examined for microbial (bacteria. mold and actinomycetes) and chemical contents (S042 ‘, Cl" and N01‘) of dust S45 pm in size. Lead contents of the collected samples were determined using atomic absorption spectrophotometry (AAS). The maximum level of lead was detected at the city Center site (588|.tg/g). The major source of lead in street dust was automobile emission. The bacteria and molds were the predominant organisms. Most of these organisms are allergenic. The results also show that the chemical compounds influenced the survival of attached microorganisms. The dust compounds may adsorb air pollutants and cause genetic effects. So that the microorganisms may be modified to more pathogenic or more environmental factor resistant.
