“…Recently, Gylseth et a1. (15) suggested that a concentration of 40-50 j.tg/l would ,correspond to the TLV of 0.05 mg/m 3 . Their conclusion was based on measurements from a few subjects only, and they used uncorrected urinary concen trations.…”

“…Moreover, the oxidation state of chromium in the air, whether tri-or hexavalent, has not been reported often. Nevertheless, maxi.mum allowable concentrations have !been proposed for urinary chromium concentrations (12,15,35,36,37). Too few dat·a exist to allow evaluatiOll1s of blood chromium measurements, but at present they seem to be of little or no value to biological exposure testing.…”

“…Moreover, the analysis of blood is an invasive test as compared to urine test and the latter could be easily introduced to the routine health control of the tannery workers. It should be mentioned that the urinary excretion of chromium has already been considered as a possible biological marker in occupational exposure to hexavalent chromium [17][18][19] but not in tannery workers exposed to trivalent species. We observed the effect of chromium only in the group with high exposure to chromium (tanning and retanning departments), so further studies are needed in order to elucidate the postulated chromium effect on iron homeostasis and for the estimation of the concentration of urinary chromium, at which the hemoglobin levels start to be altered.…”

Our aim was to investigate the adverse effects of occupational exposure to trivalent chromium. We measured chromium and iron levels in serum and urine and hemoglobin levels in tannery workers and unexposed persons. We studied three groups of subjects. Group 1 included 15 non-smoking male tannery workers highly exposed to chromium from tanning and retanning departments. Group 2 included 14 non-smoking male tannery workers with moderate chromium exposure from dying, drying and finishing departments. Group 3 included 11 healthy, non-smoking male subjects without direct chromium exposure. Higher serum chromium levels were observed in ). In group 1 an inverse association was found between serum chromium and urine iron (-0.524), urine chromium and hemoglobin (-0.594) and between the urine chromium to iron ratio and hemoglobin (-0.693, p<0.05). The results suggest a chromium adverse effect on iron metabolism, possibly associated with excessive body chromium accumulation. In conclusion, chromium urine test could be recommended for diagnosis of chromium adverse effect on iron metabolism. Further studies are needed to quantify the relationship between urine chromium and hemoglobin metabolism.

ULFVARSON, U. and WOLD, S. Trace-element concentrations in blood samples from welders of stainless steel or aluminium and a reference group. Scand. j. work environ. & heaLth 3 (1977) 183-191. The concentrations of 17 trace elements (e.g., copper, cobalt, iron, manganese, chromium, silicon and magnesium) were determined in whole blood samples of 81 persons working with different welding methods on stainless steel or aluminium and 68 nonwelders. Inorganic spark source mass spectrometry was used for the chemical analyses. The data were analyzed 'by the SIMCA method for pattern recognition (discriminant ana,lysis). No differences were found between the five groups, either in the average levels of the tmce elements or in the correlatioD structures between the trace elements. Thus no blood concentration daJta on ihe analyzed elements and collected from a single person contained any information with respect to exposure to the welding fumes investigated.
