High PM2.5 levels
The PM2.5 graphs for the last day or so are not pretty. According to DEFRA concentrations above 54ug/m³ are considered "high". As you can see from the graph below levels have been peaking above that over the last 24 hours.
PM2.5 graphs for the last day or so in Eastbourne do not make for comfortable viewing. According to DEFRA, concentrations above 54ug/m³ are considered "high". As you can see from the graph below, levels have been peaking above that over the last 24 hours.
This has brought the 24h average value up to above 40ug/m³ for the second time this week.
I am unclear on the causes of the sustained high level of pollution. What was notable yesterday evening though, was a distinct odour in the air, not obviously from the sewage works on this occasion. It smelled more like creosote, or perhaps some fumes resulting from burning plastic. The pollution was not localised either, sensors across Eastbourne were reporting raised PM2.5 levels, according to Luftdaten.
