[Exposure to selenium in photocopying workers].
The selen concentration was found in the air of 10 photocopy rooms with the mean value of 0.0025 +/- 0.0013 mg Se/m3 of the air which markedly below the maximally permissible concentration. In the same time selen was determined in serum and urine of persons in these photocopy rooms and in 22 control subjects. The mean value of selen in urine of workers in photocopy rooms was 76.50 +/- 12.60 micrograms Se/1, which is statistically significant compared with the control group which indicate that workers are exposed to selen but in a smaller degree. In the exposed subjects selen urine concentrations were higher compared to the control group with the mean value of 19.01 +/- 6.79 micrograms Se/1, but it has not been statistically significant. The selen level in urine and serum of examinees were mainly in the limits given for normal population so that the present selen exposure of workers in the photocopy rooms could not be considered harmful for human health.
