      <subfield code="a">A knowledge of the properties of airborne dusts containing compounds of Cr, Ni and Co is valuable when estimating biological monitoring methods and health risks. In this study chemical, physical and magnetic properties of alloyed steel and hard metal grinding dusts have been examined. All the grinding dusts studied showed high magnetic moments, sufficiently for the in vivo measurement of lung retained dust. The average lung retention of metallic particles among stainless steel grinders was 200 mg. Urinary chromium and nickel values for all stainless steel grinders were below the detection limit</subfield>
