title: Biomonitoring of 20 trace elements in blood and urine of occupationally exposed workers by sector field inductively coupled plasma mass spectrometry.
abstract: A sector field inductively coupled plasma mass spectrometry method for the determination of Ag, Al, As, Ba, Be, Cd, Co, Cr, Cs, Cu, Fe, Mn, Ni, Pb, Se, Sr, Tl, U, V and Zn in whole blood and urine was designed. Microwave-assisted digestion with concentrated nitric acid was used for blood samples. Urine samples were analyzed after 1/50 (v/v) dilution with 5% (v/v) nitric acid. For beryllium the necessity of medium resolution mode (R=4000) was shown. Method validation was performed using blood and urine reference materials and by analyzing of spiked samples. For the designed method relative standard deviation (RSD) for the concentration range 0.01-1.0 μg/L was 5-10%. RSD did not exceed 3% when trace elements concentrations were above 1.0 μg/L. Method detection limits (3σ): Ag 0.7 ng/L, Al 16 ng/L, As 3.4 ng/L, Ba 0.02 ng/L, Be 1.5 ng/L, Cd 7.7 ng/L, Co 1.0 ng/L, Cr 2.8 ng/L, Cs 9.8 ng/L, Cu 27 ng/L, Fe 1.1 ng/L, Mn 1.8 ng/L, Ni 17 ng/L, Pb 13 ng/L, Se 0.07 ng/L, Sr 5.7 ng/L, Tl 0.2 ng/L, U 0.1 ng/L, V 0.7 ng/L and Zn 1.2 ng/L. A developed method was applied for trace element biomonitoring of occupationally exposed workers of a beryllium processing enterprise. For preliminary risk assessment technological surface dust had been analyzed by inductively coupled plasma optical emission spectrometry. Based upon results of 50 blood and 40 urine samples analyses occupational exposure evaluation was performed. Exposure risks were found not to exceed acceptable ranges. Possible health hazards were found for Be and also Al, Cr, Mn. Occupational health and safety recommendations for the biomonitored enterprise medical care unit were issued as a result of the current investigation.
