The results show for the first time that the neurotoxin nicotine is not only removed from the skin sweat from the clothing and is detectable in all skin layers of the imitated baby skin. It also passes through the skin into deeper body layers. For comparison, the scientists repeated the experiments with donor skin of adults and came here to the same result.
In order to test whether the pollutants so absorbed have actually been proven to have harmful effects on the body, the researchers also investigated how cell cultures of the skin and nerve cells react to the smoke-welding solution. Result: In the laboratory experiment, the pollutants released from the cigarette smoke massively damaged the skin cells. For example, they changed their form and even died off in high concentration. Likewise, nerve cells, which are particularly active in the early developmental phase of humans, showed significant changes and were no longer able to network properly with each other.
"Parents should be aware that their own clothing can also serve as a carrier of the pollutants from cigarette smoke, " emphasizes Dirk Höfer. The scientists are currently working on textile coatings that can neutralize the pollutants of cigarette smoke and thus scare the Thirdhand Smoke. For the development of appropriate baby-friendly clothing is now available with the baby skin model, a versatile measuring system, the researchers said. displayHohenstein Institute dapd / science.de?
