Manish Arora studied a teenager on a computer screen, looking for important details about the past. 10-year-old son – we will call her Max – living outside the poor community in Mexico City, where lead light is a chronic problem. And show it to your teeth. Max has been around for lead from clean water and water – and even food, because the metal comes from a miter ceramic.

The on-screen picture is part of a boy’s encoded map. This shows that Max had a peak in the lead exposure before birth, in the last month of fetal development. After birth, the battle collapsed at the general level in the local population.

Blood tests can detect lead at any given time, but do not show any exposure to the past or the date and time of the event. In the teeth, Arora finds, can do two – not only for lead, but also for many other elements and chemistry. This discovery has great potential for environmental health research, such as attempts to reveal the cause of the autistic spectrum disorder.

Therefore scientists from around the world, from Mexico to Sweden to Iraq, have turned Arora, dentist and biological director of exposure at the Environmental Health Sciences Laboratory Frank Lautenberg, Mount Sinai.

He drives his teeth into the time machine.

“Imagine if you measure the levels of lead in blood here,” says Arora, pointing to the part of an already grown tooth. “You will think there is less risk, but returning to the right time, shortly before birth, there is a great jump on the lead.”

There are a few steps away from Arora Manhattan’s office headquarters that is very high, at which point he is presented with photographs of three young daughters, a large laboratory full of unpretentious equipment. But in less than a few hours, today, Arora can determine the teeth that are often eaten from years of sentimental concentration, already seen in life.

For milk teeth, which often occur until the end of the first trimester. Today’s engine is not just turning Arora into a celebrity for environmental health, but also following a field that has long focused on the dose of substance that people present in the toxic effect.

Tree of the ring when growing, like a tree, but every day instead of every year. They also formed a distinctive ring on birth, a neonatal line. Arora uses ringtones to measure, in particular the horrible, when the body is seen in certain substances. In the process, he showed a very important time to determine the type and severity of damage from chemical exposure.

Understand the drilling

A calm voice, Arora has a dental practice in India, but handed the way to consolidating the environment into his work. They did not find that the teeth contained a record of past exposure; He has learned the work of an environmental scientist using ground soils to measure the total amount of metal in the teeth.

Moreover, he was not the first person to use a laser to announce the chemical fingerprint – the geologists have used the stone in the stone. But Arora says that nature can make them combine techniques. He knows that the rings are equal in nature around the years, and they think that the growth of their teeth can be used for the same purpose.

However, in the early 2000s, he was a graduate student in Australia. When he sought funding for trying out the unconventional concepts, the scholarship was not exactly the same. He also took an unconventional approach to research, combining discipline and talking with nuclear physicists, geologists, biostatists and others rather than seeking mentors in the field. “I keep training, it’s scary,” he said.This small denture tooth, adopted by Manish Arora, may announce much more information about environmental poisons.

He is convinced of anything, he said, finding a small concession and eventually becoming a geologist who allowed him to use the planetary and terrestrial science labs when it was empty. They do not have a lock, but there is no bathroom in the lab. Without a way to go back, she quickly learned to issue water intake before she began the long night. Finally, he can work in the laboratory at night, alone, for months
