Background And Aims

The present study carried out to evaluate health effects associated with chronic occupational exposure to low levels of mercury vapors.

Methods

The study population consisted of 46 male workers occupationally exposed to mercury vapors and 65 healthy unexposed employees. Subjects were administered a questionnaire on symptoms experienced and underwent clinical examinations as well routine biochemical tests. Additionally, using standard methods, atmospheric and urinary concentrations of mercury were measured.

Results

Environmental and urinary concentrations of mercury were estimated to be 3/97±6/28 μg/m 2 and 34/30±26/77 μg/lit, respectively. While these values were blow the recommended TLV and BEI for this substance, exposed subjects had significantly higher concentrations of urinary mercury levels than their unexposed counterparts. No significant differences were noted between CBC, BUN, serum creatinine or serum activity of liver enzymes of both groups. Conversely, analysis of the data revealed that symptoms such as somatic and mental fatigue, anorexia, loss off memory and personality change were significantly more common among exposed individuals. Likewise, painful spasm of the extremities, irritability, vague fears and insomnia were more frequent among exposed population, although the differences were not statistically significant.

Conclusion

Theses observations indicate that occupational exposure to mercury vapors, even at low levels, is likely to be associated with neurological and psychological symptoms.

I. Mohammadfam, A. Kianfar, B. Afsartala Page 54

Background And Aims

Musculoskeletal disorders (MSDs) are the most important causes of workers disabilities, increasing compensations and reducing productivity in developed and developing countries. This study was aimed to determine prevalence of musculoskeletal disorders and assessment of them by using QEC and LUBA methods and comparison of results in a manufacturing company in Iran.

Methods

This descriptive-analytical study was performed on 115 operators in 15 working stations by using QEC and LUBA methods. The prevalence of MSDs was obtained by using Nordic Musculoskeletal Questionnaire (NMQ). The data were analyzed by Spearman correlation coefficients.

Results

According to findings of NMQ, 81.4 percent of operators at least in one of nine parts of musculoskeletal system have pain since 12 months ago. Assessment with QEC and LUBA revealed that 71.3 and 24.35 percent of operators respectively are in action level four.

Conclusion

According to the analysis, correlation between findings of NMQ and action levels in QEC is higher than LUBA action levels. Whereas LUBA just assess working postures, this method is not a suitable tool for evaluation of working stations that require repetitive carrying of loads, static posture and long time to do.

Background And Aims

Carbon monoxide poisoning is a major cause of mortality due to gasinhalation. It is more prevalent in winter, because of poor indoor ventilation. The purpose of our study was to evaluate exhaled carbon monoxide of students and to estimate their exposure to this gas.

Methods

This cross-sectional study was performed in winter 2008. The exhaled carbon monoxide level of 184 students was assessed by breath analyzer. Questionnaire data were collected to assess smoking habit, types of domestic exposures and symptoms of carbon monoxide intoxication.

Results

Students consists of 79 boys and 105 girls. Number of cases in carbon monoxide levelsof 0-6 ppm, 7-10ppm, 11-20ppm and above 20ppm were consecutively 150(81.52%),23(12.50%), 10(5.43%) and 1(0.54%). The difference of symptoms in different groups was not significant.

Conclusion

Due to our results, 34(18.47%) cases of healthy nonsmoker students had abnormal exhaled carbon monoxide level of more than 1-3 ppm which could be attributed to environmental exposures. 11(5.97%) cases had carbon monoxide exhaled level of more than 11ppm which exceeds the permissible exposure limits. More attention should be paid to the sources of carbon monoxide exposure in children, in order to minimize morbidity and mortality related to carbon monoxide intoxication.
