In a new video from Ron Cohen, UC Berkeley Professor of Chemistry and Earth and Planetary Sciences, the remarkable change in our atmosphere with the onset of the COVID-19 pandemic is explored. When these pollutants build up to sufficiently high levels, a chain reaction occurs from their interaction with sunlight in which the NO is converted to nitrogen dioxide (NO2). I have left it in the book anyhow. The Journal of Physical Chemistry A and ACS Earth and Space Chemistry provide platforms with wide reach for the . . However, a more serious problem is that NO2 can absorb sunlight and break apart to produce oxygen atoms that combine with the O2 in the air to produce ozone (O3).
