MERCURY IN BIOLOGICAL MATERIALS

Mercury in biological materials.

The present communication is concerned with the determination of mercury in biological materials and its normal excretion in humans. As a preliminary step in the determination of mercury in biological materials, destruction of the organic matter is essential. Mercury has a high degree of volatility and hence precautions are necessary to prevent losses during this process. There have been many c...

BIOLOGICAL MONITORING OF MERCURY EXPOSURE IN DENTISTS OF TEHRAN

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/...

Biological Treatment of Mercury Waste

A widely used method for removing mercury from polluted water is addition of sodium sulfide. Insoluble mercuric sulfide (HgS), which forms is removed as a sludge (Price et al. 1972) that is then landfilled. It has been assumed that HgS remains permanently insoluble, thus preventing movement of mercury into the surrounding environment. Mercury waste has been treated and buried in this manner for...

Modeling Growth in Biological Materials

The biomechanical modeling of growing tissues has recently become an area of intense interest. In particular, the interplay between growth patterns and mechanical stress is of great importance, with possible applications to arterial mechanics, embryo morphogenesis, tumor development, and bone remodeling. This review aims to give an overview of the theories that have been used to model these phe...
