Background Heavy metal exposure is an important cause of reduced bone mineral density (BMD). Epidemiological studies focusing on the effects mixed heavy BMD in middle-aged and older people are scarce. In single-metal studies, men women have shown distinct responses to environmental exposure. This study therefore aimed elucidate association between investigate whether it sex-specific. Methods Data from 2017–2020 National Health Nutrition Examination Survey were selected for this...
Driven by the global popularity of electric vehicles and shortage critical raw materials for batteries, spent lithium-ion power battery (LIPB) recycling industry has exhibited explosive growth in both quantity scale. However, relatively little information is known about environmental risks posed LIPB recycling, particular with regards to perfluoroalkyl polyfluoroalkyl substances (PFAS). In this work, suspect screening nontarget analysis were carried out characterize PFAS soil, dust, water...
Hot working environment not only affects work efficiency, but also poses a potential threat to the physical and mental health of staff. The current common method for dealing with high temperatures is spray-only or ventilation-only. To investigate impact different spray ventilation modes on indoor high-temperature environments, this study examined their effects environmental parameters, average skin temperature, psychological indicators. By establishing an experimental platform thermal...
This study aimed to investigate the thermal responses of acclimated workers exposed heat stress in a real work environment. The physiological indices and subjective perception 14 were measured an industrial plant. effects wet bulb globe temperature (WBGT) on studied. differences between unacclimated college students compared analyzed. relationship mean skin sensation was revealed. results show that temperature, oral heart rate increase with WBGT, while blood pressure decreases WBGT. Compared...
Solar radiation intensity affects both subjective reactions and physiological functions, especially for people who exercise heavily. Field experiments including a questionnaire survey at various ambient temperatures were performed; outdoor activities under shading (irradiance I = 50 ± 20 W/m 2 ) non-shading ( 700 conditions during summer in Xi'an recorded. The results of questionnaires indicated that when the human body reached an extremely hot state, corresponding environmental temperature...
It is beneficial for designers to identify the most important design parameters of building envelopes. This study undertook sensitivity analysis integrated with EnergyPlus assess impacts envelope naturally ventilated industrial buildings. Sensitivity coefficients six different internal heat intensities were analyzed and compared buildings in city Xi’an, located cold climate zone China. Our results showed that transfer coefficient roofs had significant impact on indoor temperature. The...
The aim of this study is to evaluate the cooling effect a spray fan in an indoor hot environment. An experimental workplace with thermal environment high temperature and radiation intensity was set up. could not meet occupational health requirements when heat source exceeded 150°C. effects air velocity relative humidity on natural wet bulb temperature, black globe (WBGT) were investigated. maximum reduction WBGT about 1.7°C, increase by 1 m/s. There notable for low velocities (e.g. 0–2 m/s),...
Abstract For practical operation of dividing manifolds, the discharge uniformity is a property generally required. To investigate dependence on manifold geometry and operating conditions, analytical solution to governing equation, Bajura's was secured. Furthermore, examples were derived by substituting experimental data into solutions; resultant curves distribution indicated essential agreement between theoretical results. evaluating distribution, index, U, introduced. The calculated results...
