Adelaide Research Scholarship: Iron-ore dust and its ...

2021-10-1  Abstract: Different lung diseases including lung cancer are the major occupational diseases among the workers of iron ore dust. However, health hazards that arise due to exposures to the ore dust vary considerably due to its variable composition in different mines. Iron oxide and silica predominantly contribute to its toxicological properties.
