Title

OCCUPATIONAL EXPOSURE TO MERCURY: AIR EXPOSURE ASSESSMENT AND BIOLOGICAL MONITORING BASED ON DISPERSIVE IONIC LIQUID- LIQUID MICROEXTRACTION

Pages

  793-799

Abstract

 Background: Exposure to MERCURY (Hg) as a heavy metal can cause health effects. The objective of this study was to assess occupational exposure to Hg in a chlor-alkali petrochemical industry in Iran by determining of Hg concentrations in air, BLOOD and URINE samples.Methods: The study was performed on 50 exposed subjects and 50 unexposed controls. Air samples were collected in the breathing zone of exposed subjects, using hopcalite sorbents. Analysis was performed using a cold vapor atomic absorption spectrophotometer (CV-AAS) according to NIOSH analytical method 6009. For all participants, BLOOD and URINE samples were collected and then transferred into sterile glass tubes. After micro-extraction with ionic liquid and back extraction with nitric acid, Hg concentrations in BLOOD and URINE samples were determined by CV-AAS.Results: The mean concentration of air Hg was 0.042±0.003 mg/m3. The mean concentrations of Hg in BLOOD and URINE samples of exposed subjects were significantly higher than unexposed controls (22.41±12.58 versus 1.19±0.95 mg/l and 30.61±10.86 versus 1.99±1.34 mg/g creatinine, respectively). Correlation of air Hg with BLOOD Hg, URINE Hg and BLOOD Hg-urine Hg ratio were significant statistically (P<0.05).Conclusions: The values of Hg in BLOOD and URINE samples of chlor-alkali workers were considerably high. Correlation coefficients showed that BLOOD Hg and BLOOD Hg-urine Hg ratio are better indicators than URINE Hg for assessing occupationally exposed workers in terms of current exposure assessment.
