  • Welding Fumes and the effects of Manganese

    The potential risks of welding operations include the potential to breathe in metal fumes and toxic gases. Fume particles are formed from the vaporisation of molten metal that occurs during the process. These particles are very fine in size and may join together to form larger particles.. The biggest risk is exposure to the manganese contained in fumes that are given off during welding. ...

  • Smudging, the why, the where and possible health concerns

    Traditions serve an important function to keep a culture’s history and to engage the community. Rituals that include smoke or incense are widespread and can be found in Buddhist temples across Asia, the Roman Catholic and Greek Orthodox churches as well as indigenous tribes like the First Nations in North America. Smudging is one of those traditions that is common for many First Nations. ...

  • A simple and fast micromethod for the analysis of polychlorinated biphenyls in air by sorbent enrichment and ultrasound-assisted solvent extraction

    Abstract  A combination of sorbent enrichment and ultrasound-assisted solvent extraction has been used to determine polychlorinated biphenyls in air. Analytes were sampled by pumping a known volume of air through a porous polymer (Tenax TA). The enriched adsorbent was transferred into a glass vial, and ultrasound-assisted extraction of the analytes was then performed in ...

  • Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer

    Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton XRF analyzer. Three separate 60-second readings are ...

  • Managing dust risks at quarries

    In the following article, Josh Thomas from instrumentation specialist Ashtead Technology, discusses the risks associated with dust at quarries, and highlights the vital role of monitoring. Background Almost all quarrying operations have the potential to create dust. Control measures should therefore be established to prevent the generation of levels that cause harm. These measures ...

  • Evaluating Guidelines for Air Sampling Methods Utilizing Chromatographic Analysis

    The following evaluation guidelines were developed to provide chemists of the Methods Development Team with a uniform and practical means for evaluating sampling and analytical methods that utilize chromatographic techniques. The guidelines define sampling and analytical parameters, specify required laboratory tests, statistical calculations, and criteria for acceptance, and provide a detailed ...

  • Tackling Occupational Hygiene

    The collective movement for solving issues surrounding work related ill health continues to gain momentum, highlighted in the HSE Help GB Work Well Scheme calling for ‘greater awareness of the harm, costs and preventability of the issue’ which should ‘drive collective action to improve health ...

  • A Complete Guide to Benzene

    Why is Benzene so hazardous? VOCs have a significant vapour pressure at normal ambient temperature which means they evaporate (volatilise) at low temperatures so they can easily enter the body through normal breathing but can also be absorbed through the skin or by swallowing material containing it. The effects on worker’s health depends upon how much benzene they are ...

  • How to Select a Portable Airborne-Particle Counter for ISO Certification of Cleanrooms

    Basics Certain factors are routinely considered for any particle counter purchase, such as price, warranty, quality, and expected laser lifetime. When selecting a particle counter for cleanroom certification it is important to consider additional factors. Of these, sensitivity and flowrate are the most important parameters, both of which determine the sampling time required to complete ...

  • What is a PID?

    Introduction PID is the abbreviation for “Photo-Ionization Detector”. A PID is a hand-held, personal, or fixed wall mounted detector that measures a broad range of volatile organic compounds (VOCs) and some inorganic compounds in the parts-per-million (ppm) to parts-per-billion (ppb) range. It gives a continuous read-out and can alarm when concentrations exceed user-defined set ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Train derailment prompts contaminated land investigation - Case study

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...
