Due to the growing number of industrial enterprises and the new ways they were used the developing city was confronted with new challenges connected with air pollution. Since residential and industrial areas were combined, more and more houses were built in direct proximity to the industrial areas.

You can see an example of this situation in Picture 3. The comparison of the surroundings of Henkel in 1922 with 1967 shows how much industrial and residential areas merged. The marked area is the area around the factory that at first was not developed at all and 45 years later (in 1967) it was completely covered with buildings.

In consequence, it is necessary to protect the now-inhabited areas in direct proximity to industrial sites against potentially dangerous air pollution. Economic interests and environmental requirements are competing with each other. Solving this problem is still the vital task of urban planning.


  1. Why did the city grow so fast?
  2. What are the consequences of living near the industrial sites?
  3. What can the community do to solve the problems related to the close proximity of residential and industrial areas?
