YOKKAICHI POLLUTION AND ENVIRONMENTAL MUSEUM FOR FUTURE AWARENESS


High Concentrations of Air Pollutants in Isozu 2205

In winter, strong winds from the northwest blow across Yokkaichi. Isozu, situated beyond the Petrochemical Complex No. 1 and across the Suzuka River, lies in the path of these powerful winds. Large amounts of soot and smoke were blown into the area from factorieswith low stack heightresulting in a high concentration of sulfur dioxide (SO2) in the air.
In the summer, soot and smoke were blown across a wide area to the northwest of the industrial complex by slow-moving winds from the southeast.
