Nanoparticle exposure
November 1st 2006 The HSE published a report in 2004 on Nanoparticles estimating that more than one million workers in the UK may be exposed to nanoparticles via incidental production in processes such as welding and refining. Traditionally, workplace aerosol exposure limits are based on mass per unit volume. TSI says recent research shows that surface area plays an important role in the toxicity of nanoparticles and is the measurement metric that best correlates with particle-induced health effects. It says a need has arisen to assess workplace conditions and personal exposure based on the measurement of nanoparticle surface area. TSI provides a range of devices to measure nanoparticle surface area. More articles from TSI Instruments Ltd: |
