               <h4>What do the Air Quality Stripes show?</h4>
               <p>These plots show the changing trends in outdoor concentrations of particulate matter (PM2.5) air pollution from 1850 to 2021.  The cleanest air in this time period is coloured light blue and the dirtiest is coloured brown.  There are many types of air pollution, but we only show particulate matter (PM2.5) concentrations as these have been closely linked to effects on human health.</p>
               <p>The data is all plotted on the same scale so a particular colour in one location is the same value as that colour in another.  We also show bar charts which show the concentration of PM2.5, we also show the World Health Organization <a href="https://www.who.int/news-room/feature-stories/detail/what-are-the-who-air-quality-guidelines" target="_new">Air Quality Guideline</a> concentration of 5 micrograms per cubic metre (or “ug/m³”).</p>
-              <p>In some plots we have added indicative air quality ratings e.g. "Very Good", "Fair", "Moderate" etc.  There is no single internationally regoginsed definition of these terms for annual mean PM2.5 values, so we have estimated these indicative values based on a mix of recomendations from different countries, as research into the health effects of PM2.5 continues we will be better understand the health effects of different concentrations.</p>
