Chemist ptfe for over half a century, Pierre Laszlo has relearned his craft teacher-researcher half a dozen times. "I felt the need to write" Funny chemistry! "To bear witness to this profound renewal," says the professor who taught at Princeton University (USA), University of Liège (ULg) and the Polytechnic University.
"In the early 2010s, the chemistry differs significantly from what it was only 20 or 30 years ago. In addition, there is no continuity between chemical science of today and that of the time of the first or second chemical revolution. Lavoisier respectively in 1789 and 1950. I chose to place myself at the interface between chemistry ptfe and society, both the science and its applications affecting the daily life of each of us. "
"The direct involvement of the chemical industry in health problems caused by chemicals remains exceptional. The risk is much greater in using products by other industries. Consumers unsuspecting packaging and containers of the products they purchase and consume. Over time, all packaging and any container diffuse components. Even if this is done by tiny amounts. "
The author of numerous scientific ptfe publications for the general public believes ptfe that it is stupid to include preservatives to ensure the longevity of the bottles sold by producers of cosmetics. The skin is permeable, these additives are soon in the blood and in users' bodies. The solution to avoid such risks? Placer cosmetics in refrigerated cabinets in retail outlets. The fridge in consumers.
Another danger phthalates. Manufactured by megatonnes each year, these additives are also found in many deodorants, shampoos, lipsticks in toys, paints, coatings for floors and walls. They make soft materials, flexible, easy to work. Improve impact resistance, cold. But their accumulation ptfe threatens.
"These plasticizers are harmful especially vis-à-vis the male reproductive system: testicular atrophy, abnormal sexual development, reduced fertility, changes in the prostate. Other worrying effects were observed on the liver and kidneys. The European regulation protects us against these agents when intervening in products made in Europe. But it is ineffective vis-à-vis Chinese products. ptfe This is far from negligible at a time when China has become the workshop of the world ".
On the front, the chemical molecules are helping suffering humanity. On one side, they allow athletes to earn a lot of money. To the detriment of their health. Chemists do they contribute to doping?
"Instinctively, chemists are reluctant to ingest or inhale any foreign molecule," said Pierre Laszlo. "Everything helps in their training and in their way of working. Substantially all of the assets in the chemical sector hard drugs are under anti-doping. With analysts training they expertisent urine samples and blood sports. They have a rich instrumentation, exceptionally sensitive and precise: chromatographs liquid or gaseous phase coupled with mass spectrometers, as well as tools ubiquitous in medical analysis laboratories. "
In 24 hours, one can test hundreds of urine and blood samples. Either a platoon of cyclists, a squad of golfers, two teams of a football match or all of the participants in a tennis tournament.
"Doping is indicative of the current hierarchy of techno. Chemistry was headed during most of the twentieth century, as it is both science and industry. But she no longer occupies that position. Since the 1990s about is biology that has taken its place. It will take almost a generation for that one realizes that doping is under the control of biological and medical applications at large. "
