Abstract
Multiple chemical sensitivity (MCS), also known as environmental intolerance, has been described as a chronic acquired disorder characterized by nonspecific symptoms in multiple organ systems and is associated with exposure to low-level chemicals. In this paper, I describe the current status of MCS in relation to industrial health in Japan, with regard to the following three points: 1) changes of MCS prevalence rate within three companies using a Questionnaire (Quick Environment Exposure Sensitivity Inventory (QEESI)) over the past 12 years. 2) current status of law on chemical substance and accreditation of occupational accidents. 3) court judgments on MCS that have occurred in work environments.
