  • Real-Time Measurement of Outdoor Tobacco Smoke Particles

    ABSTRACT The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS exposure and risk assessments.  We sought to measure peak ...

  • New ISO draft standard classifies surface particle cleanliness

    With today’s rapid technological progress and miniaturization, clean surfaces are of growing interest and vital importance for many high-tech industries and applications.The International Organization for Standardization Technical  Committee (ISO/TC) 209 is taking steps to fill the need for global standards addressing surface contamination. Since its inception in 1993, ISO/TC 209 has ...

  • Why instrument hire makes occupational safety sense

    Background Decisions concerning the acquisition of occupational safety monitoring instrumentation are often made by operational staff that may not have visibility of the full financial implications of their choices. The following article will examine the factors affecting these decisions and explain why a strategic decision to hire instrumentation can deliver substantial and wide-ranging ...

  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...

  • Air uality in IVF Labs

    Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms ...

  • Solo flight tracks global Black Carbon

    On 8th January 2012 a tiny ultra-light aircraft left Ljubljana in Slovenia on a mission to circumvent the globe using the smallest amount of fuel per distance flown whilst recording ambient levels of Black Carbon (BC) – one of the most important measures of air quality in terms of both human health and climate change. UK based particulate monitoring specialist Jim Mills from Air Monitors ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • The determination of major and minor elements in air filters and urine for hazard assessment, using a new CCD DUAL-VIEWED ICP optical emission spectrometer

    This article describes the application of a new type of CCD-based, dualviewed ICP optical emission spectrometer for the analyses of industrial hygiene types of samples. Several trace elements in air filter media are determined by ICP-OES. Urinary electrolytes and trace elements are determined in a single dilution automatically in both the axial and radial plasma viewing orientations. Results of ...

  • Persistent Organic Pollutants (POPs) in the European Atmosphere: An Updated Overview

    The industrial revolution and the resultant technological society have led to a continuous production and emission of new toxic substances causing gradual and widely diffuse adverse effects to the entire planet usually known as Global Environmental Changes. Climate change, ozone depletion and global distribution of persistent organic pollutants (POPs) are, among other, important examples of ...


  • Why monitor dust in the workplace?

    Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...

  • Air Pollution in Subway Systems May be Much Worse than we realized

    As anyone who has ridden the subway knows, the air down there is unpleasant. New research done in Canada shows that air pollution levels in Toronto’s subway system are ten times greater than those above ground. It’s a troubling realization for subway-goers, but there are ways to keep these underground systems clean. ...
