项目摘要

General-purpose techniques of the risk assessment with the continuous personal exposure monitoring were explored in this research, and it was aimed at establishing the risk assessment techniques to decide the priority of the measures and to derive the effective measures from monitored data, effectiveness of the protective equipments, and the estimation of the amount of the body intake.As for organic material, on-site measurement data were accumulated on the machine washing work, the maintenance work for chemosynthesis machines, and so on, and it was demonstrated that it was possible to know the changes in personal exposure concentration in accordance with the work practices. A part of the results was publicized in a scientific paper.As for noise, measurement were carried out and risk of hearing loss was assessed in the chemical fiber spinning process.As for aerosol, continuous monitoring of personal exposures was proved to be able to clarify instantaneous changes of exposure and identify necessary measures to reduce the exposure to hazardous substances such as a welding fume. The ventilation performance of dust-proofing devices can therefore be evaluated effectively with such continuous monitoring of personal exposures. This results was publicized in a scientific paper.Also, the research of the mathematical model which estimate the exposure concentrations of the vapor and gas of organic solvents was reviewed and the outcome was publicized, in a scientific paper. The achievements of this research were viewed to have the fundamental data of the future risk assessment research.

在这项研究中探索了风险评估的通用技术，并进行了连续的个人暴露监测，其目的是建立风险评估技术，以决定措施的优先级，并从受监测的数据，有效性，有效的措施中得出有效措施保护设备以及身体摄入量的估计。在机器洗涤工作，化学合成机器的维护工作上，有机材料，现场测量数据累积可能会根据工作实践知道个人暴露集中的变化。在科学论文中公开了结果的一部分。进行噪音，测量进行测量并在化学纤维旋转过程中评估听力损失的风险。由于气雾剂，对个人暴露的持续监测被证明能够澄清暴露的瞬时变化并确定必要的措施，以减少暴露于焊接烟雾等危险物质。因此，通过对个人暴露的持续监控，可以有效地评估防尘设备的通风性能。该结果在科学论文中宣传了。此外，还审查了有机溶剂的蒸气和气体的暴露浓度的数学模型的研究，并在一份科学论文中宣传了结果。这项研究的成就被认为具有未来风险评估研究的基本数据。
