Years of experience and personal research made me write and design this straightforward guide-book about air pollution. All the crucial information are inside this book, see the air you breathe today. Available on Paperback and Digital.
Nicholas is a Scottish boy who willhelp your kids understand better what Air Pollution is and what they need to do to combat it. Through his empowering story he will teach them how to be more sustainable and thoughtful with the environment. Available on Paperback, Digital and Limited Edition Hardcover.
AQI stands for Air Quality Index and it is the number or colour that indicates how good or bad is the air quality in your area. The problem with the AQI is the way each governments calculates the air pollution and what parameters it uses to project this Index number/colour. For example, the USA Environmental Protection Agency (EPA) considers as breakpoint for a “Moderate” NO2 concentration the value of 101μg/m3, but the UK Department for Environment, Food & Rural Affairs (DEFRA) considers as breakpoint for a “Moderate” NO2 concentration the value of 201μg/m3. The difference is huge and the Index changes dramatically for each country and at the end people get confused. The same rule applies for all the pollutants, PM2.5, SO2, O3, etc… Later they are combined all together to give us the final Index.
AQLI stands for Air Quality Life Index and only take into account the PM2.5 pollution. It is based on the finding that an additional 10μg/m3 of PM2.5 reduces life expectancy by 0.98 years. By combining this finding with satellite PM2.5 measurements around the world, the AQLI provides an insight into the global impacts of particulate pollution in local jurisdictions. The Index also illustrates how air pollution policies can increase life expectancy if pollution levels were reduced to the World Health Organization’s (WHO) safe guideline or existing national air quality standards, or by user-selected percent reductions.
Could the AQLI replace the different AQIs worldwide?
Although it gives a better insight into the impact the air pollution has to our lives, it will not be able to convince people in countries where the impact of air pollution doesn’t translate to high “Life Years Saved” numbers. For example, we can clearly see from the table below that if China adjusts their policies according to the WHO Guideline the population will have a benefit of 2.9 years. However, if Netherlands adjusts their policies according to the WHO Guideline the population will have a benefit of 0.3 years. This is rather a small number and I am afraid people won’t take it as serious in western countries as they should. In my opinion the AQLI has to take into account how our quality of life (not only life expectancy) is affected by the air pollution. We may live longer but sometimes inside hospitals, under expensive insurances and medicines that not everyone can afford even in US, Europe, etc.
Moreover, the data that you see on the table above (extracted from the original document which you can find below) do not reflect the real air quality an individual has been exposed in his a city/town/village. They have created an annual average PM2.5 concentration and the aggregations are population-weighted, which means this map won’t help an individual to understand the air quality in his/her area. For instance, there is a small town in my region called Carboneras, the population is small but there is a coal power plant there (equipped with 48 coal burners). People’s life expectancy from that village won’t reflect on the annual PM2.5 concentration because the populations is small.
I really admire this exceptional work which is done by Michael Greenstone and Qing (Claire) Fan because we need a global way to understand the air pollition and its effects. They have developed a tool which can help to inform local communities and policymakers in Asian countries about the benefits of air pollution policies in very detailed way.
Here is an interesting new face mask made and assembled 100% in Europe by a Spanish company. The AirGO offers 2 unique features that makes it very alluring to purchase and use it everyday, while you work out or commute to work.
Holidays are coming, with spare time to read some great books or give them away as a gift. It doesn’t matter which one you will choose mine, Rieuwerts’, Fuller’s or all of them, just make sure you learn more about the air you breathe. Share with your loved ones and friends the knowledge you will get.
I was looking forward to review this mask as it has a unique design to adjust around the face. They call it 360º Facial fit with zero glue and zero Formaldehyde. It is supposed to protect you from the dead ends on both sides of the nose and chin, allows to better fit the facial contours as seen on the picture below.Read More »
The battle begins, I am going to dive right into the comparison. In this comparison I am only going to compare the PM2.5 sensors because a good PM2.5 sensors says a lot about the quality of the device. The participants are:
I love when companies manage to release a second generation of their original product. In this case, Awair released the new Awair 2nd Edition a few months ago.
They clearly have learned a lot and the adjustments they have done and offer with the new version are notable at least hardware-wise. Software-wise the tweaks are small in comparison with the old version but welcome. This can be a good thing because old users can enjoy similar features like the new ones.
