Introduction to Soil Pollution

Q. Which of the following is/are responsible for soil pollution?

1. Has a high BOD as it contains both aerobic and anaerobic bacteria
2. Is processed by aerobic bactena and then anaerobic bacteria in secondary treatment in sewage treatment plants (STPs)
3. When treated in STPs does not really require the acration step as the sewage contains adequate .
4. Has very high amounts of suspended solids and dissolved salts.
