“…In the equestrian microenvironment, air contaminants are generally produced by the activities of horses and people. The generation of air contaminants can be affected by occupancy (number of people and horses) [ 27 , 28 ], building characteristics (infiltration, airtightness, and ventilation system) [ 29 , 30 , 31 ], and activity type (sweeping, feeding horses, and use of bedding materials) [ 17 ]. We found that there was an inverse relationship between volunteer worker time in the arena and barn microenvironments.…”

The foundation of healthy workplace design is an understanding of work practices. Volunteers comprise the majority of the workforce in care centers using horses to address human health issues. Documentation is lacking on protections for worker well-being in equestrian microenvironments which are known to have the potential for dust exposures. Climate acts as a master variable in equestrian facility design and ventilation usage to address dust and temperature concerns. Using climate as an independent variable, our objective was to characterize space usage, safety, environmental control, and organizational practices through a national survey of equine assisted programs. We found that more fully enclosed indoor arena spaces were in cold/very cold and mixed-humid climates (p = 0.0114). Annually more volunteers (p = 0.0073) work in these two climate groups averaging 100 volunteers per location. A total of 34% of all facilities, regardless of climate, do not use mechanical ventilation systems (e.g., fans). As volunteer worker time in the arena increased, time in the barn microenvironment tended to decrease (p = 0.0538). We identified facility designs, ventilation usage, and worker arrangements to refine the scalability of future air contaminant monitoring and to provide frameworks for education, workplace design, and prevention of exposure to dust.

“…The ambient particulate matter was studied in two European cities during New Year's fireworks [17]. The concentration and the distribution of airborne particles in were measured different cities through different researchers such as Beijing (China) [18], Wollongong (Australia) [19] Newmarket (UK) [20], Uttarakhand (India) [21], Agadir (Morocco) [22] main cities [23] and central and eastern region of Saudi Arabia [24]. One of the application to improve the human breathing zone in polluted are is by introducing a personalized air curtain 25.…”

Exposure to outdoor and indoor air particles (also known as particulate matter or PM) has attracted the interest of the scientific researchers around the world, this is because of the adverse health effects that particles have on the human. Smaller fractions of particulate matter (repairable range, ≤10 µm) give the greatest health problem, because they have the ability to reach deeper parts of the human respiratory system. Many countries have paid attention to the air pollution and made regulations to improve their indoor and outdoor air quality, Saudi Arabia, particularly Qassim region, has not given much attention to the problem of air contaminants in the ambient and indoor environments. In addition, ambient environmental parameters will be recorded. The results obtained from the indoor and outdoor measurements will help us to evaluate the air quality in Buraydah city for different seasons in the indoor and outdoor environments.

Facility for production of ambient-like model aerosols (PALMA) in the laboratory: application in the intercomparison of automated PM monitors with the reference gravimetric method

Abstract. A new facility has been developed which allows for a stable and reproducible production of ambient-like model aerosols (PALMA) in the laboratory. The set-up consists of multiple aerosol generators, a custom-made flow tube homogeniser, isokinetic sampling probes, and a system to control aerosol temperature and humidity. Model aerosols containing elemental carbon, secondary organic matter from the ozonolysis of α-pinene, inorganic salts such as ammonium sulfate and ammonium nitrate, mineral dust particles, and water were generated under different environmental conditions and at different number and mass concentrations. The aerosol physical and chemical properties were characterised with an array of experimental methods, including scanning mobility particle sizing, ion chromatography, total reflection X-ray fluorescence spectroscopy and thermo-optical analysis. The facility is very versatile and can find applications in the calibration and performance characterisation of aerosol instruments monitoring ambient air. In this study, we performed, as proof of concept, an intercomparison of three different commercial PM (particulate matter) monitors (TEOM 1405, DustTrak DRX 8533 and Fidas Frog) with the gravimetric reference method under three simulated environmental scenarios. The results are presented and compared to previous field studies. We believe that the laboratory-based method for simulating ambient aerosols presented here could provide in the future a useful alternative to time-consuming and expensive field campaigns, which are often required for instrument certification and calibration.
