Abstract : The effect of pollutants of sponge iron & steel factories on haematological profile was studied in a human population in and around the factories of Jharkhand and West Bengal. Human population were divided into two groups male and female and exposed to different doses of pollutants. There was a significant decrease in the haematological profile. Environmental pollution triggers varied and widespread allergies and disorders in the general population and affects every system of human body. Theory effecting the quality of human life. Growing number of diseases have been linked to environmental exposure.

The present study attempts to estimate the haematological parameters like HB,RBC & WBC, ESR, Lymphocytes, Monocytes and Polymorphic Leucocytes effects on human population in and around the factories. Estimation has been done after a year. Both outdoor and indoor pollution are responsible in producing respiratory infection and allergies. The main sources of outdoor air pollution are industries. Urban air pollution is largely and increasingly the result of fossil fuels used industries. Combustion processes in industries produces a complex mixture of pollutants. Substances that mainly effect on haematological indices are carbon monoxide, lead, oxides of nitrogen, sulfur dioxides and suspended particulate matters. Air polluting industries include thermal power plants, iron and steel plants, smelters, foundries, stone crushers and cement plants etc. The remarkable decrease in the HB% and other related haematological indices were found in the population living in and around the factories in comparison to normal population. Seasonal variations along with industries pollutants play important role in fluctuation of haematological indices.
