    PPM stands for parts of gas per million parts of air, and PPB is parts per billion. If that's not easy to imagine, try these examples: Part per million (ppm): 1 second in just under 2 weeks. 1 litre of water in a swimming pool. Part per billion (ppb): 1 second in 32 years. 1 ml of water in a swimming pool (that's about the size of a sugar cube).
