One third of childhood asthma cases in Europe linked to air pollution


Ever wondered if passing all those gas-guzzlers on the way to kindergarten has anything to do with your kid’s coughing? A recent research project suggests you’re right.

A team of scientists at Barcelona Institute for Global Health (ISGlobal) have studied links between childhood asthma and air pollution in Europe. It’s not exactly a micro-study in a Naples neighborhood: 64 million kids in 18 European countries are included. Their conclusion? One-third of asthma cases among European kids are linked to bad air quality.

You probably know this but asthma is a chronic inflammation. The airways between your nose and mouth and your lungs swell, and the muscles in and around those airways tighten. That can cause coughing, it can be difficult to breathe both in and out, and you can get chest pains.

The researchers have matched levels of outdoor air pollution (particulate matter, nitrogen oxide and soot) in 18 European countries with childhood asthma cases, and concluded that 66 600 childhood asthma cases could have been avoided – every year – if those countries had followed the World Health Organisation’s (WHO) thresholds for particulate matter.

Only Western European countries were included in the study, as Eastern European countries lacked air pollution exposure data. My guess is lack of data does not mean lack of air pollution or asthma…

We urgently need to reduce children’s exposure to air pollution, according to the researchers. There’s always the option to sit back and wait for politicians or the neighbor to do something about it. Alternatively, next time you walk to kindergarten, head off from the main road and walk through a quiet street instead (no, I’m not mentioning that path through the park, I’ll let you figure out that one yourself).

(Kids aged 1 to 14 are covered by the study; my almost-13-year-old would have objected strongly against being called a child, just as she will probably protest if dare tell her to follow the researchers’ advise; I might tell her to bike to school as close to the morning traffic as possible, to see what kind of response that dose receives…).

The accidental badger detector

PM2.5 levels peaked late at night and early mornings at our sensor test site and we struggled to find out why. Turns out the answer had fur and four legs.

We’re measuring pollen!

We are running our airminer 2.0 sensors to calculate local pollen levels. As expected, pollen levels vary with temperature and precipitation, but we also see significant variations through the day.

When to expect birch pollen in Norway?

Hazel and alder is flowering in Southern Norway, but the key allergen to many of us is birch. When can we expect the birch pollen season to start?

Spring in Europe – alder, hazel and birch pollen

We are heading into warmer and lighter days in Europe, lockdowns or not. And no surprise, the pollen is faithfully here.

Green in India means red in Norway

We've attempted to compare the different PM2.5 breakpoints in selected air quality indices. It turns out a green level does not mean the same around the world.

Smoke from west? No, dust from east

Did the huge forest fires on the US West Coast in September impact air quality in Europe? Not really, the measurements show. What did have an impact, was dust transported by winds from south east.

Birch pollen – the north gets the rest

The birch pollen season is almost finished in most of Central and South Europe. The inhabitants of the northern regions can still expect moderate to high levels, as the weather (finally) warms up.
