项目摘要

(1) First, the study aims to standardize measuring strategy for HCHO concentration which can apply to field investigation at various residences in Japan. In this paper, several methods were used for measuring in one room simultaneously and validated by comparison with active DNPH method. For field investigation, the detector tube is appropriate to measure HCHO concentration. Passive DNPH method is useful for determination of population exposure. We suggest that using active DNPH method with monitoring by the detector tubes, measurement should be carried out 3hours after ventilation and closing openings in occupied residences, and one night after in newly-built residences.(2) Next, Field survey on chemical pollution of 10 detached houses and 10 multiple dwelling houses was conducted using measuring method established by the first phase. The detached houses have been installed mechanical general ventilation-air conditioning systems, operating all day long, and made from the low emission … More materials. These techniques are considered to be effective mitigation measures for indoor air chemical pollution. Medical specialists also carried out Medical inspection and examination on occupants. Health effects of chemical pollution can't be clarified but the mitigation measures mentioned above are clarified to be effective for HCHO concentration reduction and not to effect VOCs concentration.(3) Two bowl shaped chambers were made by stainless originajy and tested their performance. On the experiment of compering with another chambers, the impact of different ventilation rate (N) and chamber loading ratio (L) was evaluated. It was observed that the formaldehyde emission rates from MDF vary with N/L values and the formaldehyde emission rates using these test chambers were correlated well under the same N/L value conditions. It is Important that formaldehyde emission rates should always be related to N/L value conditions as environmental conditions, such as temperature, relative humidity and surface air velocity. Less

(1)首先，本研究旨在规范HCHO浓度的测量策略，以适用于日本各地的现场调查。本文采用多种方法在同一室内同时测定，并与活性二硝基苯酚法进行了比较。对于现场调查，检测管适合测量HCHO浓度。被动DNPH法可用于人群暴露量的测定。建议采用主动式DNPH法，在探测管监测下，对有人居住的住宅应在通风关闭洞口后3 h进行测量，对新建住宅应在通风关闭洞口后一夜进行测量。(2)其次，采用第一阶段建立的化学污染测量方法，对10栋独立式住宅和10栋多户住宅的化学污染进行了现场调查。独立式住宅安装了机械式通用通风空调系统，全天候运行，采用低排放材料制成 ...更多信息材料.这些技术被认为是室内空气化学污染的有效缓解措施。医疗专家还对乘客进行了医疗检查和检查。化学污染对健康的影响尚不明确，但上述缓解措施对降低甲醛浓度有效，而对VOCs浓度无影响。(3)用不锈钢材料制作了两个碗状腔，并对其性能进行了测试。在与其他气室的对比试验中，研究了不同通风量（N）和气室负荷比（L）对气室性能的影响。结果表明，甲醛释放速率随N/L值的变化而变化，在相同的N/L值条件下，三种试验箱的甲醛释放速率具有良好的相关性。重要的是，甲醛释放速率应始终与N/L值条件相关，如环境条件，如温度，相对湿度和表面空气流速。少
