Air pollution. Air quality standards establish maximum amounts of pollutants considered acceptable in the air. The amounts are frequently given in parts per million (ppm). A standard of 30 ppm also can be expressed as follows: 30 ppm = 30 1 , 000 , 000 = 3 × 10 10 6 = 3 × 10 − 5 = 0.000 03 = 0.003 % In Problems 61 and 62, express the given standard: (A) In scientific notation (B) In standard decimal notation (C) As a percent 62. 0.03 ppm, the standard for sulfur oxides, when averaged over a year
