Parts per Million, ppm, Parts per Billion, ppb, Methods of Expressing Concentration

Multiplying 0.000001 by 1,000,000 gives a result of 1ppm. Here is a video discussing this type of calculation. In the video, the number of moles of barium present in a 1L sample of water with a barium concentration of 2ppm is calculated. 2 ppm is the maximum allowable level for barium in drinking water in the US as established by the EPA.

By applying the simulation system to some initial projects, several problems were discovered before the solutions were implemented in K.J.

Parts-per-million by mass (ppm, or ppm ) is defined as the number of units of the only types of units you will encounter in environmental engineering problems.

Concentration: It is the amount of solute present in one litre of solution.It is denoted by C or S. Concentration in parts per million (ppm): The parts of a component (A) per million parts (10 6) of the solution. Concentration in parts per billion (ppb): The parts of a component (A) per billion parts (10 9) of the solution.
