Recently a foggy morning, not just mist, not often seen these days. Presumably a result of high humidity air being quickly cooled by falling temperatures overnight. A reminder of the volume of water vapour in the air we breathe, with condensation around minute particles suspended in the air. There is so much less particle matter in the air these days as there is so much less domestic and industrial smoke emitted. However, particles of sorts still exist in suspension, such as those emitted by diesel engines or industrial effluent. I was once told that every cubic metre of air at ground level contained many bracken spores (it was on a formal course) plus assorted pollen particles. Viruses and other pathogens are also there – in the air and none can be seen with the naked eye; so there is nothing can be done, except, of course, reliance on your body’s auto-immune system developed over thousands of generations by evolution. That’s why sepsis is such bad news.
The above photo was taken in Pearson Park; it was not sufficiently dense to be defined as smog; images of the London smogs of the 1950s and ’60s make it hard to see (joke) how everyday life continued at all. Those who long for the ‘good old days’ often forget things like fogs, measles, single glazing etc. It could be along list if I had time to think about it.
