Background and aims: Cadmium is a common industrial and environmental contaminant causing adverse health effects on respiratory system and kidney. This has been classified as a human carcinogen. Biological monitoring of cadmium and its measurement in urine, hair, and nail samples can be considered as an evaluation of the internal dose. Because of trace concentration of analytes in biological sa...
Measuring heavy metal levels in the urine is an accepted method for assessing the presence of a heavy metal burden in an individual. Random samples (without a flushing agent) are excellent for showing current exposures, as they reflect the level of heavy metals in the bloodstream during the hours immediately before bladder voiding. Samples taken after using a heavy metal mobilizing agent are a ...
The authors describe their study as a ‘‘cross-sectional study’’. According to the basic definition of epidemiological terminology, a cross-sectional study determines both exposure and disease outcome simultaneously for each subject [2]. However, this study investigated only exposure to metals, without any information on health effects. Therefore, this study cannot be called a cross-sectional st...
introduction: water is an essential nutrient for life. it comprises 75% of total body weight in infants,60% in adult males and 50% in adult females. decrease in body water is commonly known as dehydration. acute or chronic dehydration is a common condition in some population groups, especialy the elderly and those who participate in physical activity in warm enviroments. potential consequences ...
background: welding can produce dangerous fumes containing various metals especially carcinogenic ones. occupational exposure to welding fumes is associated with lung cancer. therefore, welders in gas transmission pipelines are known as a high-risk group. this study was designed to determinate the amounts of metals cr, ni, and cd in breathing zone and urine of welders and to assess the possibil...
The benchmark dose (BMD) method has been increasingly used to assess the health risks of cadmium (Cd) in epidemiological studies. The aim of our study was to estimate the threshold levels of urinary Cd (UCd) using the BMD method in a general population of Jiangshan City, Zhejiang Province of China. In our study, a total of 934 people (469 men, 465 women) were recruited and morning urine samples...
Previous studies have shown links between heavy metals and many health issues. However, data on the association mortality in general population are still limited. Therefore, aim of this study was to investigate relationship overall population. We enrolled 2497 participants (1001 males 1496 females) living southern Taiwan, measured levels seven metals: lead (Pb) blood cadmium (Cd), nickel (Ni), ...
