A nationwide cross-sectional study of 3335 employees was conducted in 320 offices Japan to estimate the prevalence building-related symptoms (BRSs) and determine risk factors related work environment, Indoor Air Quality, occupational stress. Data were collected through self-administered questionnaires. The prevalences general symptoms, eye irritation, upper respiratory 14.4%, 12.1%, 8.9%, respectively. Multiple logistic regression analyses revealed that irritation significantly associated...
We assessed the risk of COVID-19 infection in a healthcare worker (HCW) from multiple pathways exposure to SARS-CoV-2 health-care setting short distance 0.6 m between HCW and patient while caring, evaluated effectiveness face mask shield using model that combined previous infection-risk models. The included hand contact via contaminated surfaces an HCW's fingers with droplets, droplet spray, inhalation inspirable respirable particles. assumed scenario medium time (MCT) long (LCT) over 1 day...
We evaluated the health status of residents and environmental risk factors housing after flooding. Questionnaires were distributed to 595 selected households (one adult resident per household) in six areas Japan which severely flooded between 2004 2010. A total 379 responses obtained. Indoor dampness visible mold growth significantly increased homes with greater flood damage. The incidence respiratory, dermal, ocular, nasal symptoms one week flooding was higher compared non-flooded homes,...
Population-based cross-sectional study was performed to estimate the prevalence of chemical intolerance and examine characteristics sample. A Web-based survey conducted that included 7,245 adults in Japan. The criteria for proposed by Skovbjerg yielded a 7.5% approximately consistent with reported from Danish population-based survey. Female gender, older age, renovation house during past 7 years were positively associated intolerance. Improvements condition observed daily ventilation habits....
Psychosocial and environmental factors at the workplace play a significant role in building-related symptoms (BRSs). Environmental change during summer cooling winter heating using air-conditioning systems. Thus, risk each season need to be clarified.A nationwide cross-sectional study was conducted Japan seasonal differences between were evaluated. Self-administered questionnaires distributed 489 offices. Possible for BRSs associated with work environment, indoor air quality, job stressors...
Mesothelioma is a malignancy with poor prognosis. It chiefly caused by asbestos exposure and its symptoms can occur about 30-50 yr after the initial exposure. This study aims to predict future trends in mesothelioma mortality Japan using method that an alternative age-cohort model. Our approach based on risk function links combined data pertaining population, size of labor force, quantity imports. We projected number deaths occurring individuals aged 50-89 for 2003-2050 functions. results...
Multiple chemical sensitivity (MCS) is characterized by somatic distress upon exposure to odors. Patients with MCS process odors differently from controls. This odor-processing may be associated activation in the prefrontal area connecting anterior cingulate cortex, which has been suggested as an of odorant-related patients. In this study, was defined a significant increase regional cerebral blood flow (rCBF) because odorant stimulation. Using well-designed card-type olfactory test kit,...
In recent years, public health problems caused by indoor air pollution have been drawing strong concern in Japan. After conducting extensive exposure assessment, governmental agencies taken effective measures to solve the problem; for instance, "Guidelines quality (IAQ)" of 13 chemicals, example, formaldehyde, toluene, and xylene, has established. Thousands chemicals identified environment. Priority rating those however, was not based on risk level. We developed a risk-screening scheme...
In recent years public health problems caused by indoor air pollution, known as 'Sick Building Syndrome in housing', or House Syndrome' Japan, have been drawing strong concern. After conducting extensive exposure assessment, government authorities taken effective measures to solve the problem. However, a result of diversification and increase quantities industrial chemicals, existing regulations do not cover enough ranges various potential hazardous chemicals. Hence, seek be changed from...
AbstractAbstractAlthough asbestos has been widely distributed in the environment, health risks due to general environmental exposure have not estimated. Future mesothelioma risk from Japan was estimated by comparing historical data and mortality attributed exposure. We developed an equation estimate environmentally-attributable based on US Environmental Protection Agency's model for occupational mortality. Based our calculations, per year of will reach peak levels 2033 range 4.8 × 10−6 1.1...
Multiple chemical sensitivity (MCS) is a disorder characterized by nonspecific and recurrent symptoms from various organ systems associated with exposure to low levels of chemicals. Patients MCS process odors differently than controls do. Previously, we suggested that this odor processing was increased regional cerebral blood flow (rCBF) in the prefrontal area during olfactory stimulation using near-infrared spectroscopic (NIRS) imaging. The aim study investigate association thresholds...
Abstract Information on air‐conditioning and ventilation has been continuously disseminated in response to the Japanese Government's announcement of need for appropriate measures against new coronavirus disease (COVID‐19), issuing an emergency presidential discourse by presidents Engineering Societies. In this paper, we add information latest knowledge behavior SARS‐CoV‐2 air, describe its diffusion characteristics built environment, summarize effects temperature humidity virus. Then...
Multiple chemical sensitivity (MCS) is a chronic acquired disorder characterized by non-specific symptoms in multiple organ systems associated with exposure to odorous chemicals. We previously observed significant activations the prefrontal cortex (PFC) during olfactory stimulation using several different odorants patients MCS near-infrared spectroscopy (NIRS) imaging. also that did not adequately distinguish non-odorant late stage of repeated test. The sensory recovery system may process...
Indoor settled dust may result in substantial human exposure to chemicals, especially by ingestion following hand-to-mouth or hand-to-object-to-mouth contact. As with other environmental media related exposure, thus be subject regulation. An international scientific workshop was convened Paris September 2019 firstly assess the relevance for public health of setting guidelines indoor dust, and secondly discuss technical challenges such guidelines. The main discussions conclusions, consensus...
