article imageHigh tungsten levels double stroke risk

High levels of tungsten in the body could double the risk of suffering a stroke, a new study suggests. The concern is with tungsten released into the environment.
The link between the metal and health risks was gathered from an analysis of the U.S. health survey, according to CBS News. The U.S. based National Health and Nutrition Examination Survey (NHANES), is a vast collection of information for 8,614 participants aged between 18 and 74, gathered over a 12-year period.
The data indicates that a high concentration of tungsten, measured in urine samples, is strongly linked with an increase in the occurrence of stroke. The presence of tungsten doubles the odds of experiencing a stroke.
Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. Tungsten is used in consumer products such as mobile phones and computers. One concern is that during the production of consumer goods, small amounts of the metal can be deposited in the environment, eventually making their way into water systems and onto agricultural land.
The research, carried out by the University of Exeter, U.K., has been published in the journal PLOS ONE. The paper is titled "High Urinary Tungsten Concentration Is Associated with Stroke in the National Health and Nutrition Examination Survey 1999–2010."
