抄録

We investigated environmental conditions in plastic houses and collected basic physiological data which might help to prevent what is called “plastic house syndrome.” The results of the study is summarized as follows<BR>1. The internal environment is closely related to the changes in external temperarure as well as the size, type, direction of house, and growing crops. Also, physiological responses were defferent according to the conditions of the internal environment and hardness of work. The current investigation confirmed that working conditions in single-type small plastic houses were worse than in multiple-type houses with same crops.<BR>2. A major facter of physiological stress for the greenhouse workers was the sudden change in temperature (16-23°C) between the inside and outside of the plastic house during the winter season.<BR>3. Since the temperature within the single-type small plastic house rises up to 50° during spring months, workers experienced more severe thermal load and mental stress from prolonged work.<BR>4. It was suggested that an improved type with a resting room might help to reduce the physiological stress and buffer the sudden change of working enviroment. Thus, it is recommended to provide a resting room whose temperarure is intermediate between external and internal temperatures, so that workers might be able to adjust themselves to the environment when they follow the safety procedures.<BR>5. It is safe to conclude that the temperature in the resting area should be kept half way between outdoor and room temperatures, even though there must be some variation with the type of house and crops. According to the current investigation, therefore, a resting area should keep the temperature between 13-16°C 28-31°C during winter and spring, respectively.
