  • Application of thermal desorption to occupational exposure monitoring

    Occupational hygiene, in its broadest sense, is the recognition, evaluation and control of health hazards arising from work – a trained hygienist needs to understand a range of subjects from health and safety legislation through to toxicology, hazardous substances, physical agents, exposure assessment and exposure control strategies. To some extent, occupational hygiene is relevant in all ...

  • Low-dose monitoring for occupational exposure and the influence of measurement accuracy

    This paper presents the evolution of individual radiation doses received by occupationally exposed workers. The individual doses accumulated over the period 2000-2007 correlated to nuclear laboratory and radiation source (gamma, X-rays) types are in the low radiation range. Dose equivalent Hp(10) was measured by a film dosimeter system; the influence of the measurement accuracy on the results was ...

  • Monitoring personal noise exposure in West end theatres with the doseBadge5 - Case study

    When the audience sits in the stalls of a West End theatre they have very little idea of the technology that goes into giving them the ultimate live show experience. Some shows enjoy runs that last for years, others aren’t so lucky, but each night there is a team of front of house staff and stagehands that bring the magic to life. The noise risks of working in a live music venue are ...

  • Professional exposure to biocides: a comparison of human exposure models for surface disinfectants

    The assessment of occupational exposure following disinfection of hard surfaces with a biocidal product based on didecyldimethylammonium chloride (DDAC) was carried out for both spraying and wiping-off applications. Several human exposure models were used, and the results were compared, in order to figure out the differences and identify the most representative model. No risk management ...

  • Exposure to radon in tourist caves in Cuba

    With the objective of estimating the dose due to radon-222 received by tour guides and other people who work inside some of the most important tourist caves in the Republic of Cuba, measurements of radon concentrations were carried out in four of these caves. All the studied caves are located in Vinales Valley (Pinar del Rio City), a very important tourist area in the country. The relationship ...

  • Dioxin Exposure and Health in the European Union

    A study on the Evaluation of the occurrence of dioxins and POPs in wastes and their potential to enter the food chainwas financed by the Environment Directorate-General of the European Commission and coordinated by the Joint Research Centre, Environment Institute, Soil and Waste Unit and aimed at investigating to what extent the use of contaminated wastes in the production of animal feedstuffs ...

  • The need for electronic noses for environmental odour exposure assessment

    This paper focuses on the opportunities for using electronic noses for odour exposure assessment purposes, especially in cases where dispersion modelling is not applicable. Such cases include, for instance, those sources where a detailed characterisation and quantification of the odour emissions for every hour of the simulation time domain is particularly difficult, due to the nature of the ...

  • Personal exposure to particulate air pollution in transport microenvironments

    Personal measurements of exposure to particulate air pollution (PM10, PM2.5, PM1) were simultaneously madeduring walking and in-car journeys on two suburban routes in Northampton, UK, during the winter of 1999/2000.Comparisons were made between concentrations found in each transport mode by particle fraction, between differentparticle fractions by transport mode, and between transport ...

  • Chemical Exposure from Imported Food Products

    Chemical Exposure from Imported Food Products Requirement for Routine Monitoring Due to the large quantities of food being imported by countries in today's global markets, routine monitoring of these imported products for chemical contaminants is essential to ensure compliance with chemical safety regulations. Chemicals that have long been removed from the supply chain for products and ...

  • Challenges for exposure prediction in Ecological Risk Assessment

    Evaluating organism exposure in the ecosystems is a difficult task and can be carried out measuring or predicting concentrations in the environment. While current regulatory approaches favour a modelling approach, they either use a static representation of the environment and of the chemical discharge or a simplified dynamic approach (e.g. dealing with pesticides). Improving the ecological ...

  • Controlling Exposure to Noise at Work with Personal Noise Dosimeters

    Which method is best to monitor noise: sound level meter or noise dosimeter? Controlling exposure to noise at work with noise dosimeters Our work environment has been transformed since the 1970’s with the introduction of new machinery and technical equipment designed to improve and increase general productivity. This has revolutionalised the way we operate ...

  • Review of toxicological effects caused by episodic stressor exposure

    Water quality monitoring tools that rely on data from stress‐response tests with continuous exposure at constant concentrations are not always appropriately protective when stressor exposure in the field is episodic in nature. The present study identifies various approaches that have attempted to account for episodic stressor exposure, describes the development of a toxicological effects database ...

  • In-Vehicle exposures to particulate matter and black carbon

    ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

  • Beat the Heat: Occupational Exposure to Heat and Hot Environments

    With summer underway, now is the perfect time for organizations to examine their policies and procedures regarding employee heat exposure, especially in light of the recently published document from NIOSH titled, “Occupational Exposure to Heat and Hot Environments”, Publication Number 2016-106. What is the ...

  • Chemical analysis of fish bile extracts for monitoring endocrine disrupting chemical exposure in water: Bisphenol A, alkylphenols and norethindrone

    This study determined concentrations of estrogenic bisphenol A (BPA), nonylphenol (NP), octylphenol (4‐tert‐OP), butylphenol (4‐tert‐BP) and progestogenic norethindrone (NET) by LC‐MS/MS in bile extracts from field fish in Xin'an River and market fish in Shanghai, China. Compared to the field fish, EDC concentrations in market fish bile were at relatively high levels with high detectable ...

  • PureAire Methyl Bromide Monitor Gains Exposure from Lowered 5ppm criteria to 1 ppm Limit

    There has been an increased awareness for methyl bromide safety in the past few months. A year ago a worker got sick from breathing high levels of off gassing methyl bromide in a warehouse where commodities were being stored. Commodities coming from overseas must be fumigated in ports, or warehouses upon arrival. September 1, 2011 the California EPA will announce the regulations for methyl ...

  • Monitoring exposure of brown bullheads and benthic macroinvertebrates to sediment contaminants in the Ashtabula River before, during, and after remediation

    In 2007, approximately 420,500 cubic meters of contaminated sediment were removed from the Ashtabula River by dredging. The primary objective of this study was to monitor contaminant exposure in fish and macroinvertebrates before, during, and following dredging. This was done by measuring tissue concentrations of polychlorinated biphenyl (PCB) and polycyclic aromatic hydrocarbon (PAH) in brown ...
