The phrase "alter concentrations" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or any field where adjusting the levels of substances is relevant.
Example: "To achieve the desired reaction rate, we need to alter concentrations of the reactants in the solution."
Alternatives: "adjust levels" or "modify amounts".
But it's uncertain whether the guidelines, despite their good intentions, will dramatically alter concentrations of public projects and, in some cases, whether they should.
Like pharmaceutical antidepressants, ayahuasca seems to alter concentrations of the mood-boosting neurotransmitter serotonin in the brain.
In fact, immunizations with plasmids, encoding either AD epitope vaccine or irrelevant antigen, did not alter concentrations of cytokines in the brains of mice (data not shown).
The output follows from the chemical transformations of the reaction that alter concentrations.
Because cholesterol is the substrate from which reproductive hormones are synthesized (Burger 2002), exposure to PFAAs have the potential to alter concentrations of bioavailable circulating hormones.
As noted above, climate change could alter concentrations of particulate matter as a result of increased wildfires or changes in pollutant transport mechanisms and thus influence pregnancy outcomes.
Most of all, loop diuretics alter concentration abilities as well to dilution abilities, in contrast to thiazide diuretics which only affect the latter [207].
In the spine and adjacent dendrite, calcium influx is allowed to directly alter concentration of calcium involved in biochemical signaling; we term this calcium 'global calcium'.
Most of all, loop diuretics alter concentration abilities as well to dilution abilities, in contrast to thiazide diuretics which only affect the latter [ 207].
The findings of our meta-analysis identified significantly altered concentrations of cytokines in ASD compared to HCs, strengthening evidence of an abnormal cytokine profile in ASD where inflammatory signals dominate.
Notably, HapA shows a suggestive association with body mass index and altered concentrations of the hunger-satiety hormones ghrelin and leptin in males, indicating that the selective advantage of HapA may have been mediated through effects on energy metabolism.
