“…But people that live near smelters that process copper ore into metal, do experience this kind of exposure. People that live in houses that still have copper plumbing are exposed to higher levels of copper than most people, because copper is released into their drinking (C. Steinhausen, et al, 2004) "water through corrosion of pipes. Occupational exposure to copper often occurs.…”

Tea is the most common beverage used in everyday life by everyone. Tea contains a large number of possibly bioactive chemicals, including flavonoids, amino acids, vitamins, caffeine and several polysaccharides. It has been suggested that green and black tea may protect against cancer, though the catechins found in green tea are thought to be more effective in preventing certain obesity-related cancers such as liver and colorectal cancer, while both green and black teas may protect against cardiovascular disease. Negative effects of tea drinking are centered around the consumption of sugar used to sweeten the tea. Those who consume very large quantities of brick tea may experience fluorosis. Numerous recent epidemiological studies have been conducted to investigate the effects of green tea consumption on the incidence of human cancers. These studies suggest significant protective effects of green tea against oral, pharyngeal, oesophageal, prostate, digestive, urinary tract, pancreatic, bladder, skin, lung, colon, breast, and liver cancers, and lower risk for cancer metastasis and recurrence and a variety of health effects have been proposed and investigated .In present study six tea samples of different brands (Broke Bond Taza, Dhadkan, Patakha, Razana, Red lebel and Tata tea) were analysed for Cu, Ni, Pb, Cd, Cr and Ca. Trace metals like Cu, Ni, Pb, Cd, Cr and Ca were found to be within the permissible limit given by WHO.

“…Biokinetic models do exist with urinary excretion and blood retention predictions validated by human testing. 9,10 However, the previously developed models largely depict the kinetics of aluminum in a physiochemical framework rather than within an ICRP-like anatomical framework. In order to create a more anatomically intuitive systemic model structure for aluminum biokinetics, a comprehensive literature search was completed.…”

“…Nolte and Steinhausen developed a model, but this model was found to be lacking and needed modifications in order to grant higher anatomical resolution, in a more anatomically intuitive form. 9,10 A new aluminum model of familiar ICRP form created in order to properly implement aluminum bioassay monitoring. The details of this model are contained in Section 4.…”

ABSTRACTThe current state-of-the-art munitions development by the United States Air Force creates potential exposure scenarios wherein soldiers and laboratory workers may inhale nano-phase aerosols. The primary metals of present interest in this study are aluminum, boron, tantalum, titanium, and tungsten. The contained work describes efforts made to develop a software package capable of analyzing, and predicting, bioassay measurements of workers and soldiers following exposures to the metallic aerosols. The resultant software package (chemIMBA) developed by Dr. Alan Birchall of Public Health England was created by tailoring a pre-existing software package for radioactive aerosol exposures called, Integrated Modules for Bioassay Analysis (IMBA). Biokinetic model selection, and implementation, was conducted for boron, tantalum, titanium, and tungsten. For aluminum, a new systemic biokinetic model was created, and implemented within chemIMBA. Exposures to three different post-detonation blast-aerosols for open air, and enclosed environment scenarios for laboratory workers were simulated using the newly developed chemIMBA software. Intake Excretion Fractions, and Intake Retention Fractions, for time periods up to ten thousand days post-exposure were predicted for exposure scenarios of soldiers and laboratory workers.15.

“…Commercial teas, in spite of the fact of being produced from young leaves shoots, contain relatively high concentrations of aluminum, becoming a potential source of bioavailable aluminum in the diet [5][6][7][8][9]. Matsumoto et al [4] have reported concentrations around 30,000 mg·kg -1 of aluminum in old tea dry leaves.…”
