Unit ppt [10¹²]
Name part per trillion
Category Mass Fraction
Details In the field of mass fraction, the unit part per trillion (ppt) is a measure used to express extremely low concentrations of a particular substance in a mixture or solution. It is represented as 10¹², which means one part of the substance of interest per one trillion (1,000,000,000,000) parts of the mixture, by mass.

For instance, if a substance is present at a concentration of 1 ppt, it means that there is 1 gram of the substance for every 1 trillion grams of the mixture.

This unit is commonly used in environmental and analytical chemistry to measure the concentrations of pollutants, contaminants, or trace elements in air, water, soil, or other media. Since many of these substances can have significant effects on human health or ecosystems even at very low concentrations, expressing their concentrations in parts per trillion helps to accurately communicate the presence of such trace amounts.
