Two-year-old Thayi loves the aerosol remedy room at Senegal’s Albert Royer Youngsters’s Hospital, the place she will get to go to sleep on her mom’s lap, respiration deeply – one thing that’s often exhausting to do.
The masks over her face pumps out medication that soothes her asthmatic lungs, a situation worsened by air air pollution.
The hospital within the capital, Dakar, has a big unit devoted to respiratory points.
Dr Idrissa Ba, who has been working there for 15 years, says the variety of sufferers retains rising and rising – one thing he thinks is linked to worsening air high quality within the metropolis.
Dakar does have notably dangerous ranges of outside pollution or tiny particles, generally known as particulate matter (PM), which is how air pollution is measured.
Air air pollution: What’s particulate matter (PM)?
- Microscopic particles that may be inhaled into the lungs and trigger critical well being issues
- The particles are available in many tiny sizes, usually from site visitors fumes, and could be made up of lots of of various chemical compounds
- PM10 – particles of 10 microns and smaller in diameter (one micron is one thousandth of a millimetre)
- PM2.5 – particles of two.5 microns and smaller in diameter, about 20 occasions smaller than a grain of sand and sufficiently small to get into the blood stream
- Proof is rising that PM can restrict the expansion of kids’s lungs
- Researchers are investigating the potential results of those particles on situations resembling dementia
- About seven million individuals are estimated to die every year from publicity to fantastic particles that penetrate deep into the lungs and cardiovascular system
These particles can attain deep into the physique with the hazard of inflicting lasting harm to individuals’s well being.
In keeping with the World Well being Group (WHO), a secure stage of PM10 must be 20 and the extent of PM 2.5 must be 10.
In Dakar, the common ranges are 146 for PM10 – seven occasions greater than beneficial – and 30 for PM2.5.
That is in response to Senegal’s centre for air high quality management, whose director, Aminata Mbow Diokhané, says it is very important perceive that almost all cities don’t respect the suggestions.
She provides that Dakar is likely one of the solely cities in Africa to measure air high quality each day.
Others on the continent are prone to have far worse ranges, she says.
Africa’s ‘soiled gasoline’
There are two fundamental the explanation why air high quality in Dakar can get notably dangerous:
- Pure air pollution. Yearly in the course of the dry season, an disagreeable wind, generally known as the harmattan, blows in mud from the Sahara.
- Air pollution from trade and vehicles. With a rising inhabitants, the variety of vehicles and buses on the roads maintain growing in Dakar.
And whereas there are extra vehicles in London or Tokyo, these in Dakar trigger extra harm to the surroundings as a lot of them are previous or second hand, that means they pollute extra.
It is true that now we have an issue with automobile air pollution, however right here individuals additionally burn their garbage exterior within the open”
Extra considerably, gasoline imported to Africa incorporates a lot greater ranges of sulphur than that utilized in Europe or the US, as an investigation in 2016 by Swiss marketing campaign group Public Eye revealed.
This implies vehicles utilizing “soiled gasoline” emit extra poisonous gasoline thought-about a serious pollutant.
“Immediately the diesel requirements in Senegal are nonetheless at 5,000 components per million as in comparison with Europe at 10 components per million,” Jane Akumu, a spokeswoman for the UN Atmosphere’s Air High quality and Mobility Unit advised the BBC.
Anybody who walks round Dakar or drives with their home windows open is most of the time submerged by clouds of thick black smoke coming from surrounding exhaust pipes.
“The excellent news is that in December 2018, technical specialists from the area met in Abidjan [in Ivory Coast] and agreed to harmonise low sulphur gasoline requirements in various West African nations,” Ms Akumu stated.
This nonetheless must be permitted by heads of state, however specialists hope that by the top of the 12 months all gasoline imports to the area, together with to Senegal, may have decrease sulphur ranges.
For Dr Ba this could solely be excellent news.
“We have completed research on the impression of air pollution on youngsters’s well being and we concluded there’s a very vital correlation between the extent of small particles and the variety of sufferers having bronchial asthma assaults,” he says.
However he believes extra guidelines must be introduced in to control automobiles and says it’s also about altering attitudes.
“Air pollution is an issue that impacts everybody so the response should be world, however individuals must also be extra accountable, pollute much less,” he says.
“It is true that now we have an issue with automobile air pollution however right here individuals additionally burn their garbage exterior within the open, for instance.”

Youngsters are notably affected as a result of they breathe extra air than adults, in proportion to their measurement, and their organs usually are not totally developed.
The typical age of sufferers at Albert Royer Hospital is 5.
