Nanoparticle exposure October 1st 2006 The occupational health risks associated with nonoparticle exposure is a topical and emerging issue for health and safety professionals. The HSE published a report in 2004 called Nonoparticles: An Occupational Hygiene Review. At the time it estimated that more than one million workers in the UK may be exposed to nanoparticles via incidental production in processes such as welding and refining. Exposure to nanomaterials may occur through inhalation, dermal contact and ingestion. Traditionally, workplace aerosol exposure limits are based on mass per unit volume. However, TSI Instruments 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. The company says a need has arisen to assess workplace conditions and personal exposure based on the measurement of nanoparticle surface area. TSI Instruments provides a range of devices to measure nanoparticle surface area, particle count and size distribution. More articles from TSI Instruments Ltd: |
