It can be used when discussing how one variable influences or changes the level of concentration of another variable, often in scientific or analytical contexts.
Example: "The introduction of a new variable can significantly affect the concentration of the solution over time."
Alternatives: "influence the level of" or "impact the amount of".
The Harvard ambient particle concentrators do not affect the concentration of gaseous pollutants, therefore, minimizing the confounding due to gaseous co-pollutants such as ozone and sulfur dioxide.
Various chemical reactions within the lake system also affect the concentration of dissolved oxygen.
Will it affect the concentration of atmospheric carbon dioxide in beneficial ways and slow the pace of climate change?
The case centered on a manufacturer's new water conservation plans, how the change would affect the concentration of chemical discharge at its factory, and which EPA regulations would apply.
The aeration cascades removed approximately 67% of the dissolved CO2 initially present but varying the design did not affect the concentration of Fe(II) leaving the treatment ponds.
