Workers in salt factories, who inhale large amounts of salt particles, are at risk of high blood pressure due to the increased salt intake. A study published today in the Open Access journal Environmental Health shows for the first time that breathing in large quantities of salt particles has just the same effect on blood pressure as eating a salty diet. Wearing face masks and plastic eyeglasses is enough to protect workers who are highly exposed to salt from salt-related high blood pressure.
A high consumption of salt has been shown to be directly linked to high blood pressure and the development of cardiovascular and kidney diseases, which are major causes of mortality worldwide. The European Food Safety Authority recently issued an opinion stating that current salt intakes in Europe far exceed nutritional requirements and may cause adverse health effects.
The present study, conducted by Kripa Haldiya and colleagues from the Desert Medicine Research Centre in Jodhpur, India, provides new data suggesting that inhaling large amounts of salt particles has the same effect as consuming a salty diet and increases blood pressure considerably, thus putting workers in salt factories around the world at risk of high blood pressure. This study represents the first demonstration of an occupational hazard linked to table salt.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
