दूषण (en. Contamination)

8. No contamination and low noise.

Now the contamination came from where?

The clean fuel-servicing equipment should be used to avoid contamination.

There should be no contamination of stone pieces or chemical manures etc. in the mud.

However, my contamination by the toxins of Satan was too deep.

Such contamination was sought to be proved by testing the T.T. retention sample in the laboratory at Barauni Terminal.

Contamination can happen during transportation and storage, too.
