Evaluation of occupational exposure in a slide bearings factory on the basis of urine and blood sample analyses

Abstract

The impact of a slide bearings factory on its workers was examined. Urine and blood samples were collected from 42 workers and six people employed in the offices in the same factory (control group). Concentrations of Al, Cu, Pb and Zn in blood and urine samples were measured twice (before and after chelation therapy) by ICP-MS technique using standard addition method. The essential differences in concentrations of elements for workers and control group were evaluated using non-parametric Mann-Whitney U-test. Significant differences between workers and control group were found for Pb in blood and Al in urine samples. The study was also undertaken to indicate correlation between blood and urine element content, workers' ages, their period of work and work section. It was also found that intravenous administration of 1 g of calcium-disodium versanate significantly increased urinary excretion of Pb and Zn, but not Al.

“…Censoring level was 83% for Cr, 79% for Mn and 62% for Sr. Concentration of Cu is comparable with data presented by Rai«ska et al [16]. Concentration of Mn is one order higher than reported by Kucera et al [17] (0.0092 ppm)…”

“…These results also indicated that hair and toenail samples are useful in the evaluation of that impact. Workers of the slide bearings factory are occupationally exposed to elements, which can be harmful to their health (Raiń ska, Biziuk, Jaremin et al 2007). No significant correlations were observed between the level of elements, workers' age, and period of work.…”

“…An impact of Federeal-Mogul BIMET S.A. in Gdansk, the biggest manufacturer of slide bearings in Poland, on occupational staff was also examined (Raiń ska, Biziuk, Jaremin et al 2007). Basic materials used in the production of bearings are bimetal strips with bearing alloys.…”

“…An ultrasonic bath was used to improve washing efficiency. Concentration of Al, Br, Ca, Cl, Cu, K, Mg, Mn, Na, S, Se, V, and Zn in hair and toenail clippings were determined by instrumental neutron activation analysis (INAA) at the Interfaculty Reactor Institute in Delft (The Neatherlands), at a 2MW swimming-pool nuclear reactor (Raiń ska, Biziuk, Jaremin et al 2007).…”
