2,000-5,000 ppm : PM2.5 - no safe level The NSW Government's “Action for Air” (2009) acknowledges PM2.5 are particularly dangerous: “ Health research identifies particles of less than 2.5 micrograms (PM2.5) as a particular concern because their smaller size means they can be inhaled deeper into the lungs, and because there is no safe threshold level to use for setting standards . The annual average concentration of PM 1, PM 2.5 and PM 10 in both stations were 18.24, 32.23 and 60.01 μg m-3 respectively. The PM 1, PM 2.5 and PM 10 concentrations in roadside varied from 13.46 to 25.59 μg m-3, 20.82-49.85 μg m-3 and 45.90-77.23 μg m-3 respectively. 2017-12-28 I did find two graphs on two different sites talking about the PM2.5 levels.

The current EPA standard for PM exposure is 12 µg/m³. Ozone levels as low as 30 parts per billion, also the lowest measured, increased the risk of death as well. The current standard is 75 ppb, with a planned phase-in to a 70 ppb level approved by the Obama Administration in 2015 now seriously in doubt. Created by Dean Leffingwell, Scaled Agile Framework (SAFe), is an approach to scaling agile practices across an enterprise.
The 24-hour standard was set at 65 μg/m 3 based on the 3-year average of the annual 98th percentile concentrations. Indoor PM levels are dependent on several factors including outdoor levels, infiltration, types of ventilation and filtration systems used, indoor sources, and personal activities of occupants. In homes without smoking or other strong particle sources, indoor PM would be expected to be the same as, or lower than, outdoor levels.
