Is it true that silverware becomes black faster today than it did 50 years ago?

The above statement is true.

Silverwares become black because of the formation of a skinny layer of silver sulphate on them by means of reacting with hydrogen sulphate inside the air. Fifty years ago, the presence of hydrogen sulphide inside the air was comparatively lesser because of less pollution in the environment. Thus, silverware becomes black faster today than it did 50 years ago.
