===Increase in atmospheric pollution===

A study presented at the [[American Geophysical Union]] meeting in [[San Francisco]] found that light pollution destroys [[nitrate]] [[Radical (chemistry)|radicals]] thus preventing the normal night time reduction of atmospheric smog produced by fumes emitted from cars and factories.<ref>{{cite news | url=https://www.bbc.co.uk/news/science-environment-11990737 | work=BBC News | title=City lighting 'boosts pollution' | date=2010-12-14 | access-date=2018-06-22 | archive-date=2021-06-03 | archive-url=https://web.archive.org/web/20210603043113/https://www.bbc.co.uk/news/science-environment-11990737 | url-status=live }}</ref><ref>{{cite web | url=http://www.agu.org/cgi-bin/SFgate/SFgate?language=English&verbose=0&listenv=table&application=fm10&convert=&converthl=&refinequery=&formintern=&formextern=&transquery=au%3dstark&_lines=&multiple=0&descriptor=%2fdata%2fepubs%2fwais%2findexes%2ffm10%2ffm10 | title=Nighttime photochemistry: Nitrate radical destruction by anthropogenic light sources }}{{Dead link|date=July 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> The study was presented by Harald Stark from the [[National Oceanic and Atmospheric Administration]].
