  • Many Japanese today are suffering from health disorders related to their living environment, such as allergies and hypersensitivity to chemical substances. The Sick House/Building Syndrome has been a serious problem since 1996, due to low level exposure to hazardous chemicals such as formaldehyde and volatile organic compounds (VOCs) emitted in airtight houses. This paper aims to show current status of the syndrome in Japan and practical researches to promote prevention of, and improvement to indoor air pollution due to chemicals.

  • The average and maximum temperature were $29.5^{\circ}C$ and $33.2^{\circ}C$ at 2:00 p.m. respectively, in the plastic-film house covered with shade net, and both of temperature were lower $0.6^{\circ}C$ and $1.3^{\circ}C$ than those of conventional shade. Light transmittance was 14% in the plastic-film house, while 9.9% in conventional shade during growing season from May to October. Withering time of aboveground part was on October 3rd in conventional shade with 60% of withering leaf, while it was on November 10th with 3.7% of withering leaf in the plastic-film house, about 40 days longer survival. The main disease incidence were 15% of anthracnose, 17% of leaf spot, 5% of phytophthora blight and 3% of gray mold in the conventional shade, while 0 ~ 0.1% disease incidence and 95% of emergence rate in the plastic-film house. The growth in the aboveground and underground part of ginseng was totally better, particularly characteristics affecting yield such as root length, main root length and diameter in the plastic-film house. The fresh weight was increased by 128% compared to the conventional shade and harvested roots per $3.3m^2$ were 36 roots in the conventional shade and 58 roots in the plastic-film house and futhermore yield per $3.3m^2$ was increased by 216% compared to the conventional shade. As covering materials, the rice straw in the plastic-film house was excellent. The ginsenoside contents affecting the quality of ginseng were higher in the plastic-film house indicating 0.333% of Rg1, 0.672% of Rb1, 0.730% of Rc and rate of red rusty root was less than 4.0 ~ 6.1%. Above the results, the quality of ginseng grown in the plastic-film house covered with shade net was improved than that of the conventional shade.

  • High temperature and natural sun light are considered as the core conditions for high quality and large quantity of Phellinus baumii production. However still now on there has been a mistake of excessively cutting off the natural light by spreading the closing nets on the mushroom cultivating house. For an example there are many houses where the closing nets under the roofs be extended to cover the sides of the houses, which way prevents the mushrooms in the houses from receiving sufficient natural sun light and getting the temperature sufficiently to grow so that the quantity and quality of the produced mushrooms are lowered even though the mushrooms can grow in those conditions. In order to avoid this mistake, the closing nets must be placed on the roofs of the houses only without dropping them to cover the sides. Further more when the closing nets are placed triply at the beginning stage of Phellinus baumii's growth in the house, the nets restrain the internal temperature of the house going up and intercept the natural bright light flowing into the house so that the growing tardiness occur to the Phellinus baumii. Therefore the roof only must have been covered by the closing net for 65% cutting off the light until May, and then covered by double folded the net for June, triple folded the net for July and August, double folded the net for September, and the single net for October. When the ventilation in the house has been maintained until the house tightly balloon out through controling lifting force of internal air, the Phellinus baumii can grow well while the bed logs themselves aren't dried out. Marketing is also very much important as well as increasing quality and quantity of Phellinus baumii production.

  • The purpose of this study was to identify the influence of living factors on TVOC(Total Volatile Organic Compounds) concentrations and personal factors to reduce the Sick House Syndrome for newly-built apartments. The field measurements of TVOC concentrations were made totally 30 times(5 times per one subject house) in six apartment units in which residents recently moved. Those apartments authorized its business approval before May 2004, the Act of Indoor Air Quality Management for multi-use facilities. The Questionnaire surveys of residents' subjective responses on the Sick House Syndrome were carried out in 2nd measurement of each house. Respondents consisted of 20 residents living in the measured houses. The findings were as follows: The TVOC concentrations of the measured subject apartments ranged from about 1/10 of the recommended standard for multi-use facilities($400{\mu}g/m^3$) to up to 90 times as high as the standard. Since then, the Recommended Standard of Indoor Air Quality Management for newly-built apartment house was announced in December 2005. In accordance with this standard($2390{\mu}g/m^3$) it ranged from about 1/100 to up to 15 times as high as the standard. The subject house whose TVOC concentrations reduced below the recommendation standard in the shortest period had the largest amount of ventilation (all the windows were open for ventilation in the past three months) among all measured houses. The reason of another house whose TVOC concentrations were much higher than the rest was fronted with new furniture in the room. There turned out to be no apparent relations between the TVOC concentrations and the residents' individual responses of Sick House Syndrome. The responses were serious in those who stayed in their new houses for a long period or had disease like allergy. It's recommended that they should open all the windows for at least three months for ventilation in newly-built houses, and it would be better to avoid remodeling than needs be.
