formaldehyde/fatigue

This paper studied associations between volatile organic compounds (VOC), formaldehyde, nitrogen dioxide (NO2) and carbon dioxide (CO2) in schools in Malaysia and rhinitis, ocular, nasal and dermal symptoms, headache and fatigue among students. Pupils from eight randomly selected junior high schools

Gas sensors based on reduced graphene oxide (rGO) films and rGO/MoS2 hybrid films were fabricated on polyethylene naphthalate substrates by a simple self-assembly method, which yielded flexible devices for detection of formaldehyde (HCHO) at room temperature. The sensing test results indicated that

Cadavers are usually preserved by embalming solution which is composed of formaldehyde (FA), phenol, and glycerol. Therefore, medical students and instructors have a higher risk of exposure to FA inhalation from cadavers during dissection. Therefore, the objective of this study was to evaluate the

Formaldehyde is a flammable, colorless and readily polymerized gas at ambient temperature, and is one of the major pollutants in indoor air. Medical students during their dissection course are exposed to formaldehyde, whose exposure is recently considered to be one of the causes of multiple chemical

OBJECTIVE Our purpose was to clarify whether subjective symptoms of low-level formaldehyde (FA) exposure in medical students were transient or persistent and to investigate whether the allergy state changed as a result of exposure. METHODS We surveyed the prevalence of medical students' subjective

To study formaldehyde concentrations in the breathing zone and symptoms induced by gaseous formaldehyde exposure of medical students and instructors during gross anatomy laboratory at faculty of Medicine, Thammasat university. Formaldehyde concentrations in the indoor air and breathing zone of

Twenty-one subjects exposed to formaldehyde (at levels between 0.12 and 1.6 parts per million [ppm]) in two mobile trailers and the remaining 18 unexposed workers of the same workforce were examined by questionnaire and spirometry. Symptoms of eye and throat irritation and increased headache and

Previous investigators have reported the occurrence of both allergic and non-allergic systemic complications due to exposure to formaldehyde gas. However, little is known about the pathogenic link between formaldehyde-induced clinical symptoms and patch test results, or about the long-term effects

Medical surveillance of Catania public sector employees who use video display terminals (VDTs) revealed complaints of eye and upper respiratory tract irritation, skin rash, headache, mental fatigue and reduced concentration in some of the workers. These were employed in three recently renovated

This article aims to build up a simple, rapid and accurate capillary zone electrophoresis (CZE) method for the separation of biogenic amines (BAs). Here, 10 key BAs (phenethylamine, histamine, tryptamine, tyramine, 5-hydroxytryptamine, octopamine, dopamine, norepinephrine, epinephrine and carnosine)

Chemical intolerance is a phenomenon observed in multiple chemical sensitivity (MCS) syndrome, an ill-defined disorder in humans attributed to exposure to volatile organic compounds. Amplification of symptoms in individuals with MCS resembles the phenomenon of psychostimulant- and stress-induced

Formaldehyde (FA) is an occupational and general indoor hazard often affecting the respiratory airways. One of the main causes of multiple chemical sensitivity is gaseous FA, and it has become an important social problem in developed countries. FA concentrations in anatomy dissection classrooms are

OBJECTIVE To test two hypotheses. First, autonomic healing is achievable in a commercially available poly (methyl methacrylate) bone cement brand that is widely used to anchor total joint replacements. Secondly, in this self-healing cement, the fatigue crack propagation (FCP) rate is critically

BACKGROUND Children attending a primary school showed symptoms such as headache, cough, rhinitis and epistaxis. Assessment of specific IgE to formaldehyde gave positive results in some children. OBJECTIVE Was IgE-mediated sensitization as well as symptoms in children associated with formaldehyde

Many anecdotal cases and some clinical studies have demonstrated that formaldehyde exposure can cause multiple health-related problems and cerebral dysfunction. The U.S. Consumer Product Safety Commission has documented multiple hazards related to formaldehyde exposure. Some of this research has
