PPM is used to measure low concentrations in aqueous solutions or in soil. In solutions, ppm refers to mg/liter or grams/m3. Note that it represents a ratio of mass to volume. This can be done because the mass of water is the same as its volume (in Metric units). In the soil test report, ppm usually stands for mg/kg, so that 1 ppm = 1 mg/kg

What is a PID ? A Photo-Ionization Detector measures VOCs and other toxic gases in low concentrations from ppb (parts per billion) up to 10,000 ppm (parts per million or 1% by volume). 2015-05-12 · Prior to the Industrial Revolution, natural climate variations caused atmospheric CO 2 to vary between about 200 ppm during ice ages and 300 ppm during the warmer periods between ice ages. At the dawn of the Industrial Revolution, around the year 1780, the CO 2 concentration was about 280 ppm, so CO2 had already risen by around 40 ppm before Keeling began his measurements. 400 ppm Healthy adults will have headaches within 1-2 hours.

The doublet signal at 2.18 ppm implies that a $\ce{\sf{-CH2-}}$ group is attached to a carbon having only one proton.
