In Japan, the Air Pollution Control Law, which regulates the emission of air pollutants aiming at conserving the ambient environment, was enacted in 1968. Current status of air pollution has been improved compared to the period of severe environmental pollution. However, further measures should be taken to eliminate SPM and photochemical oxidants because of the status of air pollution by these substances. Voluntary efforts by business entities as well as measures on stationery sources and mobile sources under the Law are attributed to the improvement of the status. An issue in improving ambient environment is that the achievement status of EQSs regarding photochemical oxidants remains low. Total number of days of which the photochemical oxidant warning was issued was 189, increased by approximately 75% to FY 2003. Air pollution by Suspended Particulate Matter (SPM) has been improved in FY 2004, with the compliance rate of 98.5% for ambient air pollution monitoring stations (APMSs) and 99.6% for roadside air pollution monitoring stations (RAPMSs) respectively. However, it’s not enough because there still remains areas where regional air pollution occurs.
In this context, measures to control volatile organic compounds (VOC) emission, the material causing photochemical oxidants and SPM, is crucial. To this end, the Air Pollution Control Law was revised in May 2004 to include VOC
