Virus lockdown brings clean air bonus to Fylde coast

Scientists have noticed a drop in the amount of air pollution in our towns and cities as the number of cars on the road has dramatically fallen.
Bus companies across Lancashire have reduced the number of services as have train firms operating in our area.

UK air navigation service NATS said that the number of commercial flights has dropped by 77 per cent, with the fall higher in other European countries such as Spain, Germany and France.
It said for example, on March 25 there were 1,415 flights handled, compared to 6,224 flights on the same date the year before.
From Sunday, Blackpool Transport stared running reduced services and suspended all tram services, while rail operator Northern is running only “key worker” timetables (See https://www.northernrailway.co.uk/key-worker-timetables ) with just a couple of trains a day running.

In March last year, the Department of Health said air pollution was “the biggest environmental threat to health in the UK, with between 28,000 and 36,000 deaths a year attributed to long-term exposure”. Some studies put the figure at 40,000 deaths.
Satellite images have revealed dramatic reductions in concentrations of nitrogen dioxide in China and northern Italy, coinciding with lockdowns.
Professor Nick Hewitt, from Lancaster University, said: “Many air quality monitoring stations around the country are showing significant improvements in air quality since the lockdown began. 20-40per cent decreases in the concentrations of small particles and the oxides of nitrogen, compared with the pre-lockdown period, are typical.

“Although these air quality improvements will reduce the number of premature deaths caused by air pollution it may be that many individuals susceptible to air pollution will also be susceptible to the most severe effects of Covid-19.”
Scientists from the University of York processed data from roadside monitoring sites in York, Birmingham, Glasgow, London and Manchester.
They found a significant reduction in Nitrogen Dioxide for car exhausts and particulates.

"I would expect them to drop even further over the coming weeks.
