Default Air pollution particles linked to Alzheimer's disease

Tiny magnetic particles produced by car engines and brakes can travel into the human brain and may trigger Alzheimer's disease, scientists have warned.

Researchers at Lancaster, Oxford and Manchester Universities discovered microscopic spheres of the mineral magnetite in the brains of 37 people in Manchester and Mexico who had suffered neurodegenerative disease.

Well I have a question in mind after reading this report. Do these kind of particles enter the car if one has put the AC in recirculation mode?

When on bike, I feel a burning sensation in my wind pipe when I drive through polluted areas like Graphite India here in BLR, so stopped taking that route and switched to borewell road route.It is very much important to get a mask (something like Vog Mask) when you are on a two wheeler.

Having AC in re-circulation mode does not stop all outside air from entering the car. Car is not air-tight as such. However, yes it obviously cuts out dust and smoke to a large extent compared to driving with glass down or with re-circulation mode off.

I usually drive with re-circulation mode ON, still there are instances when outside odur seeps in randomly.

That apart, your car AC filter if equiped will also cut out part of dust particles.

Some interesting facts about pollution levels. Interesting for India, Karnataka (along with Kerala and parts of Andhra) seems to have less pollution. Maybe due to western ghats and lack of manufacturing industries.

Interesting link about fossil fuel pollution
http://cdiac.ornl.gov/trends/emis/tre_coun.html

In percapita pollution levels, India ranks 147th ! Population control is the only way to control pollution levels.

Ah my favourite topic and one where I can go into considerable details if necessary. Chemtrails may not be a reality but this is closest to chemtrailing done by ourselves on a daily basis and the vehicles are a weapon in this regard.

Cars pollute in the following ways :

1) Factory paint-job - Single largest source of particulate matter pollution (over 40%) as paint particulates filled with certain heavy-metals and clear-coats have isocyanates. Both cause nerve damage and/or asthma

2) Carbon monoxide, amongst the deadliest gases ever, is emitted by your car during regular running. Thank nature for diluting it to the point of becoming impotent, but man still tries his best by buying more and more vehicles.

3) Fibreglass production - As deadly as asbestos, fibreglass is used extensively while making dashboards.

4) Asbestos - the most dangerous particulate substance ever.. capable of shredding the lungs to a point of no-recovery, is used in brake-pads and linings, 2 portions which are subject to friction and wear. Worst idea ever.

5) NOx - Produced by both fuels though a much higher quantity is emitted from diesels. This is also part of the particulate emissions and affects asthma sufferers directly.

6) Sulfur dioxide (SO2) - Another result of burning fuels and another gas which causes nerve damage and breathing problems.

7) Particulate matters - AKA soot, as simple as that. Can be found being emitted by the tonnes by trucks which are a 100 years old and still running.

8) Carbon-dioxide - Cars mimick our lungs, it draws in massive amounts of oxygen and puts out carbon-dioxide. Both actions are harmful to the environment in general.

We may love driving, and cars but that should not stop us from knowing all the facts about how they run.. just so that we can jointly take action for a better tomorrow by not only using our resources more judiciously but also realising how cars need to be run/maintained. Stopping the driving is never a solution, enjoying each drive no matter how short, is.

If this map is indeed even halfway right, then what about the Thar desert area? Ought it not to be marked yellow - Im sure that there, like in the case of the Western Ghats and the Himalayas, there are no polluting Industries.
Similarly what about the great tracts of Northern Forests, wherever there is a lot of tree cover? Huge tracts of MP, Bihar, JH, WB, OR etc ought to show up as yellow, not orange...

I saw this world map of air pollution.

http://maps.who.int/airpollution/

Something is not right. Why all the poorer developing countries in red so uniformly, while most first world countries are in the green? Even the greenest parts of India are in red. While even most polluted parts of America are at the most yellow? The Sahara desert is in purple, how is it getting polluted?

Very interesting map! And a nice question!

The Sahara experiences a phenomenon called the Saharan Air Layer where significant amounts of dust are lifted up in the air, and a lot of it in fact makes its way over and across the Atlantic (see this page). East Asia has its own version called Asian Dust.

The following satellite imagery shows long clouds of dust from the Sahara (bottom) making its way across the Atlantic to South America (top).

These are at least partial contributors to the deep reds seen over the Sahara and Eastern China in the map you've linked to. I would assume that the deserts of the Middle East also contribute to the deep reds there.

The following image shows how atmospheric dust and dust that is falling to earth range in the PM2.5 category, which is what the WHO map you linked to is tracking.

This is also corroborated by this study which shows how the Asian Dust phenomenon raised the PM2.5 readings in the mainland US - and this is after crossing the even larger Pacific Ocean!

This is not to diminish the impact of industrial, construction and vehicular pollution, but to also acknowledge powerful natural forces at work.

There are definitely political factors at work in the map you've linked to - and I don't necessarily mean that in a malicious way. If you look at the Alaska-Canada border, or the US-Mexico border, there's a clear difference at the line. Now I know Trump hasn't yet built his wall, so this can only mean there are some regional differences/variations in how data is being measured or baselined.
