On 31 October 1997 air quality in a number of UK urban centres was poor. High concentrations of nitrogen dioxide were measured in Birmingham, Bristol, London, Lincoln and Reading. Nitrogen dioxide levels were highest on 31 October, peaking at 257 parts per billion at Camden Roadside. A table summarising the highest hourly nitrogen dioxide concentrations that occurred on that day is shown below. On 4 November 1997 there were no occurrences of poor or very poor air quality at any national UK monitoring site.
