Author(s): Marjan Assefi*, Khadijeh Onsory and Alireza Iranbakhsh
Nanoparticles measures from 1 to 100 nanometers in diameter are chemically different from their corresponding bulk materials and their potential toxicity can vary according to dozens of characteristics, such as size, surface area and coating. In 2009 researchers claimed that nanoparticles were responsible for lung damage. Two workers in a printing factory in China in Beijing died (Nature 460,932/2009). Researchers at a meeting said that safety testing was needed for products containing nanoparticles, products that can be absorbed by the body like; food, cosmetics and perfumes in which nanoparticles are used in their colors or in their textures. The workers who work in an occupational exposure to nano.. Read More»
