Creatinine adjustment of biological monitoring results

Creatinine adjustment of biological monitoring results.

BACKGROUND Biological monitoring (BM) aids exposure assessment but where this is based on incomplete collections of single urine voiding measurement of creatinine is often used to adjust analyte concentrations for the effects of fluid balance. AIMS To provide reference data on creatinine concentrations in urine samples from a population of UK workers. METHODS Urine samples sent to the Healt...

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/...

Benchmarking Automatic Bundle Adjustment Results

In classical photogrammetry, point observations are manually determined by an operator for performing the bundle adjustment of a sequence of images. In such cases, a comparison of different estimates is usually carried out with respect to the estimated 3D object points. Today, a broad range of automatic methods are available for extracting and matching point features across images, even in the ...
