Progressive increase in the concentration of non-biodegradable substances in a food chain is called biological magnification.

The level of these harmful substances will go on increasing from one trophic level to the next. When certain harmful substances enter the food chain at the level of primary producers,-they get concentrated many times at each subsequent trophic level.
