BIOLOGICAL MONITORING OF MERCURY EXPOSURE IN DENTISTS OF TEHRAN
نویسندگان
چکیده مقاله:
In order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). Subject data and pertinent health symptoms were asked via a questionnaire. The results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/L, while 27.2 percent of dentists had levels within normal limits (0-19 µg/L). The results also showed that values for general practitioners tended to be higher, but was not significant for the specialists. The data demonstrated that there is an association between health symptoms pertinent to mercury poisoning and urine mercury values above 50 µg/L

متن کاملHuman biological monitoring of mercury for exposure assessment
Mercury (Hg) is a naturally occurring element that has metallic, inorganic and organic forms, each with their own implications for human health. Exposure to mercury primarily occurs by inhalation of metallic mercury vapors and by dietary intake of organic mercury. Early health effects are often not well detected. Therefore, determination of the internal dose is a valuable approach in primary pr...

متن کاملAssessment of exposure to lead through air and biological monitoring in a lead and zinc mine
Background and aim: Lead is ubiquitous and one of the earliest metals discovered by the human. This metal is widely used in different industries due to its important physico-chemical properties like softness, high malleability, ductility, low melting point and resistance to corrosion. Lead absorbed in body with several routs and when transfer in blood is primarily in red blood cells. Human exp...
متن کاملVisual impairment on dentists related to occupational mercury exposure.
A detailed assessment of visual function was obtained in subjects with low-level occupational mercury exposure by measuring hue saturation thresholds and contrast sensitivity functions for luminance and chromatic modulation. General practice dentists (n=15) were compared to age-matched healthy controls (n=13). Color discrimination estimated by the area of Mac Adam ellipses was impaired, showing...
