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
The sensitizing potency of formaldehyde and phenol exposure during 4 weeks of an anatomy dissection course was assessed in 45 medical students. Specific IgE against formaldehyde by RAST and by ELISA and specific IgE against phenol by ELISA were assessed before and after the course. At the start of
Formaldehyde (HCHO) is a common chemical found in occupational and residential environments and has been suggested as a cause of asthmalike symptoms in some individuals. Clinical and animal studies suggest that HCHO adsorbed on respirable particles may elicit a greater pulmonary physiologic and
Formaldehyde has recently been declared a potential carcinogen. Occupational health authorities throughout the world are therefore likely to put stricter regulations to its use also within anatomical disciplines. We have been able to reduce the atmospheric concentration of formaldehyde in our
The Texas Department of Health sampled for formaldehyde (HCHO) in 443 mobile homes between April, 1979, and May, 1982, at the request of the occupants. Colorimetric detector tubes were used most frequently for sample acquisition. HCHO concentrations ranged from below detectable limits (less than 0.5
This paper explores the dose-response relation between formaldehyde (HCHO) concentration and reported health complaints (eye irritation, nose/throat irritation, headaches and skin rash) of nearly 2,000 residents living in 397 mobile and 494 conventional homes. The study analyzes the effects of HCHO
The catecholaminergic innervation of cranial dura mater in humans was studied by examining several dural zones (vascular, perivascular, intervascular) in different regions (basal, calvarial, occipital, frontal, tentorial, parietal, temporal). The results demonstrate that catecholaminergic nerve
A family with chronic exposure to formaldehyde in a renovated apartment is reported. The source of exposure proved to be chipboard. The family members' symptoms were eye and upper airway irritation, malaise, headache, nausea, sleeping disturbances, irritability and lack of appetite. At first the
The evaporation of formaldehyde from cadavers can produce high exposures among students and instructors. A possible causal role for formaldehyde has been considered likely for tumor of the nasopharynx and the nasal cavities in human beings. Due to this reason, Japan Ministry of Education, Culture,
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
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
BACKGROUND
The sensitizing potency of formaldehyde and phenol during anatomy dissecting was investigated. The objective was to determine whether exposure induces specific IgE or IgG against formaldehyde-albumin or phenol-albumin.
METHODS
In 27 medical students, specific IgE against
OBJECTIVE
Aim of the present study is to evaluate the air pollution produced by formaldehyde in pathological anatomy.
METHODS
This study was made with instrumental approach based on environmental evaluation of 10% formaldehyde used in pathological anatomy, by an infrared gas analyser (Brüel &
A questionnaire study among 70 employees at seven mobile day care centers where urea formaldehyde glued particle board has been used for indoor paneling and among 34 employees at three control institutions selected at random where no particle board has been used as building materials, showed a
Free formaldehyde may be released from wood products and foam insulation where urea-formaldehyde resins have been used. From January, 1978 to November, 1979, 100 structures were investigated by the Wisconsin Division of Health after receiving complaints of health problems from occupants. Air samples
