Abstract

Respirable-size (< 5 μm) and coarse fractions (particle size 5-20 μm) of airborne dusts were sampled by a personal sampler. Welder mist, airborne dust associated with grinding processes and control groups were sampled in a metal processing assembly shop; heavy metal content of the dusts was measured. Only the concentration of manganese of the welder mist was higher than the maximum allowed concentration (MAC) value. The respirable fraction of the airborne dust can reach the deeper portion of lungs; therefore, the distribution of toxic metals in the two size-fractions is of great importance. Two workshops, i.e. grave-stone polishing and cutting and tile stove demolition, were investigated. The heavy metals accumulated mostly in the respirable-size fractions independent of the workplace and working procedures.
