niskie stężenie

Now, I did use a lower concentration because of her small size.

They are found in very low concentrations, usually less than 5%.

At low concentrations this takes a very long time to happen.

A treatment plant would only need concentrations much lower than 1%.

Lower concentrations of tea tree oil do not seem to be as effective.

Another such factor is the low concentration of the compound.

The effect of the latter compound is present only at low concentrations.

It also occurs in tea tree oil at a low concentration.

By comparison with other parts of the world, the deposits are present in very low concentrations.

This means that lower concentrations can be used in animal feeds.
