BIOSIS COPYRIGHT: BIOL ABS. Fourteen welders, welding stainless steel using the Tungsten Inert Gas method, were monitored for one work-week. During this time, measurements were taken for chromium (Cr), water soluble hexavalent Cr (CrVI), and nickel (Ni) in air, as well as Cr and Ni in the blood and urine of the welders. The welders provided a history of their previous exposure to Cr and Ni, their use of personal protective equipment, and their smoking habits. The CrVI in the air was generally below the detection level. Total Cr and Ni in air were frequently below the detection level, and generally below 10 mug/m3. The levels of Cr and Ni in blood were from below the detection levels to 1.0 mug. In the urine, levels were below 2.0 mug/g creatinine and 8.5 mug/g creatinine for Cr and Ni, respectively. Some welders had slightly elevated levels of total Cr in the urine that could result from bystander-exposure as derived from Manual Metal Arc welding performed in the same workplace.
