8 most polluted cities in India
Number of people affected: 1,560,667 (2001 cencus)
Type of pollutant: High dust and smoke particulate
Source of pollution: Industrial units
Every morning as the sun rises, you can see a thick layer of black dust over 40 villages on the outskirts of Chhattisgarh capital Raipur. That is probably all the proof you need about the spread of industrial pollution in the area.
Some 145 units based within a 20-km radius around Raipur have been identified as being "red category" industries because of their high pollution levels. These units have been operating even though they haven't installed pollution controlling equipment.
This has resulted in some one million people in Raipur and 40 nearby villages suffering from respiratory and skin cancer diseases.
Forced by repeated public protests, public interest litigation (PIL) and criticism by the local media, the government disconnected power to several units in recent months temporarily for not complying with pollution control norms.
