Putting measurements into context

A copy of William Blakes’s iconic monotype print of Isaac Newton is one of the works selected by Marianne Faithfull  for the DLA Piper Series: Innocence and Experience, exhibition  being shown at Tate Liverpool until 2 September. It’s unusual for scientists to be portrayed in art, and at first glance Newton appears as a heroic

Sampling for Sulphuric Acid Mist

Tomorrow I’m travelling over to Leeds to attend a seminar organised by the Chemical Industries Association seminar  on Controlling and Measuring Occupational Exposure to sulphuric acid mist. I’ll be making a brief presentation on sampling methodologies. I’ve uploaded a copy of the presentation to my Slideshare site, and it can be viewed below. Exposure to

Variability in exposure measurements

Whenever an occupational hygienist carries out an air sampling survey, either for a group of workers carrying out the same tasks in a similar way, or for the same individual worker carrying out the same job on different days, it’s inevitable that a range of results will be obtained.  However, although most people would probably

Ultrafine particles in the environment

Yesterday I logged into a webinar run by the instrument manufacturer, TSI, on “Exposure to Ultrafine Particles- Indoor, Outdoor and In-Vehicle Concentrations: Sources, and Particle Dynamics”, presented by Dr Lance Wallace a leading researcher in the measurement of ultrafine particles. The potential risks to health from sub-micron ultrafine particles has been a high profile occupational

Measuring hazardous substances

To me, the main aim of occupational hygiene is controlling exposure to hazardous agents, including hazardous substances, to do that its important to understand the degree of risk. That’s the only way we can ensure we’re directing our effort, energy and money at the real problems. With hazardous substances, measurement of their airborne concentration is
