After John Kennedy Jr.
Many reports say the accident was caused by heavy fog caused by high temperatures and humidity in the area.
But a senior cleaner at the University of Florida gave a different explanation.
He told a Miami newspaper that smog in the eastern states was almost always caused by sulfur floating in from coal.
Power plants in the Midwest. JFK Jr.
His wife and sister were actually the victims of a thick cloud of dust pollution.
This story is one of many revelations found in hannahholmess\'s book, The Secret Life of dust.
As a natural and scientific writer, Holmes became interested in dust in an assignment by GobiDesert, and \"came back with dust from the brain.
\"The research in her book clearly shows that dust is far from what we might think of as a dry subject. From the globe-
Holmes showed us the dust of the Sahara, the dust that plagues our carpets, and the space dust that sprinkled on all of us every day, no matter how humble the dust is, it plays an amazing role in our life.
Here is the secret of some dust collected by the author from the interview.
Observe scientists around the world
Dusty rivers like pollution set the stage for Kennedy Airport
The tragedy is that dusthas has far more ability to travel than we thought.
Particularly harmful soft coal is a major source of energy in China, and now an estimated 1 million Chinese people die each year, which also hinders the growth of Chinese crops.
On 1998, the polluted river, as well as the dust from the Gobi Desert, passed through the Pacific Ocean and emitted dust --
Pollution levels in Washington and Oregon are two levels.
The third federal restriction set to protect the lungs of the human body.
This \"Asian Express\" is a fairly common phenomenon, and this dusty river of Asia extends to the Midwest, where it may eventually rain.
Although this has not happened yet, under certain conditions, the contaminated dust could theoretically reach a lethal concentration in the United States. A much better-
The more famous dust River than the Asian Express is the dust layer of theSaharan, which is too big for sailors to notice it a century and a half ago.
But until recently1967)
Did scientists really find dust in Africa in the New World?
They built a cliff.
The top network on the island of Barbados is trying to capture the cosmic dust that space physicists like to study.
Only this time, the dust they captured was red.
Brown, not cosmic dust or coral dust after Analysis (
They might think)
But Migrating dust from the Sahara
As a result, dust scholars began to trace the dust of the Sahara.
In 1993, they monitored a wave of things that swept the Caribbean;
Over Alabama, Mississippi and Louis Anna
In most parts of Texas.
It then soared north to Illinois, eventually covering the entire East Coast. This globe-
Some unbelievable phenomena are caused by dust from Saran.
For example, the island of Jamaica in the Caribbean has some of the world\'s richest bauxite.
The aluminum mine, which is known as the aluminum ore, is the aluminum mine we started to produce in the United States.
But scientists don\'t know where the Earth comes from.
After all, the bottom soil of Jamaica is coral, which does not contain this mineral.
But the Sahara is rich in aluminum.
It seems that for millions of years from the beginning of the Sahara, these bauxite beds are likely to explode.
The tropical surface soil of the Caribbean islands is a gift to the African desert.
Of course, dust and disease dust also have a bad side.
2,000 years ago, Roman naturalist Plinythe Elder noticed that people who mine and weave asbestos often get sick.
We now know that asbestos dust can cause cancer, and recently, researchers believe that some types of asbestos are more deadly than others ---
The kind of needle-
The shape of the fiber slides through the body\'s defense system and is buried in the lungs.
The body does not deal with these lethal needles, because they are difficult to perform by macrophages, which the body uses to do the job.
In a variety of occupations, quartz dust is another villain leading to a fatal illness, hence its name: stone grinder rot, stonemason disease, mine asthma, and Potter rot.
These quartz dust actually kills the macrophages, causing the body to issue a \"bandage-
Make \"cells that weave fibers around them \".
Soon, the size of these bandages became larger, interfering with lunge\'s ability to fly.
The result is silicone lung.
In a more open disease known as the black lung, due to the inhalation of carbon-
Rich in coal dust, dust particles of macrophages simply pile up together, and similar \"bandages-making\"results.
About 1,500 miners die each year from coal mine dust.
Other natural toxic dust includes lubricants, talc and graphite, which are also used for pencil lead.
There are also plant dust such as cotton, wheat, barley, coffee and Cork.
Micro blame and asthma explosion (
Including the dust rabbits hidden under your bed)
According to Holmes, this may be very strange.
From Space diamonds to Sahara dust, to dinosaur bones and some modern tire rubber, a little fluff can contain \"everything \".
\"It may also\" contain toxic lead and long
Banned pesticides, dangerous molds and bacteria, cancer
Resulting in smoke particles, and samples of all the convenient chemicals that we innocently distribute in our house in the name of cleaning.
\"The Dust of the House is also full of allergies --
It causes small mites, predatory mites, and fake spiders that hunt and kill them.
Indoor dust pollution is one of the leading suspects in one of the world\'s most widespread epidemicscentury--
That is, the \"subtle outbreak\" of asthma \".
Since 1970, the number of people with asthma around the world has increased by 50% every decade, and researchers do not know why.
There are many theories.
Genetic, once the main suspect, has withdrawn from running.
Another suspect is allergic.
People who are allergic to certain components of indoor dust are more likely to develop asthma.
Of course, there is also a surge in allergy cases.
Some people believe that the hotter houses, carpets and furniture are too tight to allow dust and dust to be washed away (
Tiny creatures living in dust).
But there is also a theory that in our modern way of life, the lungs do not get enough exercise to fight against dust.
Another theory, the so-called
Known as the \"hygiene hypothesis\", it shows that our modern houses are not dirty enough and, therefore, we do not have tolerance for the dust we encounter.
Whatever the reason for asthma, if we have allergies or asthma, one of the worst things we can do is clean the house, Holmes said. Old-Old brooms
Simply sweep away the allergens and breathe them into the air.
The same is true of vacuum cleaners.
On the 1990 highway.
The high-efficiency particulate air filter comes in to filter out all the tiny particles that can penetrate the lungs.
Unfortunately, only about 30% of vacuum cleaners with HEPA filters meet the requirements of the carpet and carpet Institute
Third place in federal outdoor sports
Limit the dust while collecting a lot of dirt from the carpet.
A dust expert in Seattle flatly said that normal vacuuming would not move the deep dust on the carpet, and that the dust on the old carpet could be between 8 and 170 grams per square meter, or between three forks and 1/2 cups of dust.
Holmes quoted Seattle dust expert John Roberts as saying that he talked about the dangers of carpet dust today, especially for children: \"For a crawling child, the risk is not small . \"
For example, the best prediction of how much lead is in a child\'s blood is how much lead is in carpet dust. . . .
We calculated that the average infant consumed the same amount of benzol. a-pyrene--
Strong carcinogens-
From the dust he gets from smoking three cigarettes a day.
This is a general carpet.
Some carpets are hundreds of times the number.
However, going back to allergies and asthma, the areas of those main suspects, dust worms, proved to be particularly interesting for Holmes, who found these tiny creatures \"more attractive\" than those creepy micro-gray Photos\"looking bugs. \"They\'re cream-
Color and gloss.
\"They are jumping on carpet fibers with amazing diligence,\" she wrote . \".
Their main task is to eat the dead skin of the human being dumped by the car.
To our credit, the dust mites did a lot of cleaning work for us.
In fact, they may also eat mold, thus getting rid of another suspicion, rhinitis in the rising wave.
Unfortunately, allergens produced by dust worms affect about 20 million Americans who are highly allergic to dust worms.
But is the dust worm the cause of asthma?
It may not be, and it is logical to reason, because the mites need water, Holmes said.
In fact, mites cannot survive in most parts of the Western United States. S.
The weather there is too dry for them.
They also \"avoid the cold, dry Finland where asthma is raging.
\"At the moment, the answer to the relationship between house dust and asthma is proving the secret,\" Holmes wrote . \".
The key to the asthma epidemic remains to be discovered.
But the other more cosmic secrets about dust are about to be revealed: our solar system, for example ---
It\'s earth, planet and sun. -
It\'s actually made of dust.
By studying about 100 tons of space dust sent to Earth every year, astrophysicists have a lot of knowledge about where the dust comes from.
According to the latest theory, our solar system is made up of dust from 10 to 100 ancient dead stars, and scientists believe they can even identify the types of stars involved.
The conclusion is humble, but inevitable. -
We are made of recycled materials!
Perhaps even more humbling is the assumption of NASA researchers that he is working with \"space-
\"When he drops the molecules to higher places, the molecules quickly assemble into hollow, waterproof spheres,\" Holmes wrote . \".
He said that certain molecules made of dust, like cells, may be an integral part of life.
Because there is dust everywhere in the universe, the potential of life is everywhere.
For those of us who just see dust as an annoying thing to brush off coffee tables and computer screens, reading hannahholmes\'s secret life of dust will ensure one thing: we will never look at dust again in the same way.
