Cancer-related deaths due to air pollution in Dilovasi Industrial Zone, Turkey


It is reported that about 300 large and small scale industries are located in Dilovasi Organized Industrial Zone among which 193 are active and that roughly 20,000 people are employed in these. The majority of these represent the metallurgy and chemical sectors. Altogether, these companies comprise 17% of Turkeys industry. The bowl shape topographic structure of Dilovasi and the presence of iron and steel smelting plants as well as paint and chemical facilities negatively influence the air quality of the region. Research studies based on death records have been conducted demonstrating that cancer-related cases range over the worlds and Turkeys averages. In regional measurements, the PM10 air pollution indicator was confirmed to be 3,5 times higher than the accepted limit value.
