TOXICOLOGICAL PROFILE FOR CHROMIUM - Davidborowski.com

CHROMIUM 2252. HEALTH EFFECTS5 females (Lukanova et al. 1996). The ambient total chromium worker exposures ranged from 0.009 to0.327 mg/m 3 (median 0.041 mg/m 3 ), chromium(VI) ranged from 0.0005 to 0.13 mg/m 3 (median0.003 mg/m 3 ). No exposure measurements were provided for the control group. The results showed thatmean chromium concentrations in lymphocytes of workers were 115 µg/10 12 cells as compared to controlvalues of 64 µg/10 12 cells, and for erythrocytes were 2.1 µg/10 12 cells for workers and 0.19 µg/10 12 cellsin controls. Preshift and postshift mean urine chromium levels were 4.2 µg/g creatinine and 8.9 µg/gcreatinine, respectively. The control group urine levels were 0.99 µg/g creatinine. Chromiumconcentrations in the lymphocytes were correlated with workplace chromium(VI) air levels (r=0.59,p15 µg/g creatinine had increased retinol binding protein and tubular antigens in the urine.The workroom levels ranged from 0.05 to 1.0 mg chromium(VI)/m 3 as chromium trioxide (Franchini and
