low concentration

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.

Another such factor is the low concentration of the compound.

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

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

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

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.

They usually come in small quantities and have low concentrations of the active chemicals.

The bacteria can also survive at low concentrations of oxygen.

We also found lower concentrations in smokers although this did not reach significance.

Although found in low concentrations, these pollutants pose risk on a large scale.

This low concentration thus appeared to be sufficient to cause the toxic effects.

The hazard is in chronic exposure, even at low concentrations.

At low concentrations the oil has the smell of rotten eggs.

Except for very low concentrations, active solar tracking is also necessary.

Vanadium may be required by some plants, but at very low concentrations.

Significant levels of stabilization are achieved at relatively low concentrations.

Regulations vary, but low concentrations, such as 3%, are widely available and legal to buy for medical use.

Of perhaps greater importance, the toxin works at extremely low concentrations.

Low concentrations can also be applied to the skin.

It burns a bit, but in the low concentration.

Equally, at lower concentrations the pigment breaks up and looks blue.

The state has the second lowest concentration of union workers in the United States.
