High Concentrations of Air Pollutants in Isozu2205
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.
