First poppy and hygienic, then disgusting: Plastics convert more and more to our health problem
Whether in the ground or in the air, in remote mountain lakes or in the depths of the oceans, in the Arctic or in the hot climates – microplasty you can now find everywhere, even in our food. Everybody takes on average fun grams of that in the week – the weight of a credit card.
How these little plastic particles act on human health is not yet clarified – there are still relevant data. The Federal Office for Risk Assessment (BfR) reported two years ago, at least from polysteroline particles no danger to the intestinal health of humans. That had experiments with mines and human intestinal cells. But this finding did not apply to other plastics.
Many questions are still open in this context: how do the additives that give the plastics give their special characteristics? In which exhibition can these particles can bind pollutants from the environment? Or in what mabe, health-risking microorganisms can thrive on the surface of these particles?
Science has now progressed a step: a current study of the University of Bayreuth shows that numerous pathogenic fungal types are laid down on the plastic particles. "We can watch all stages of fungal biofilm formation on the microplasty particles", Said Gerasimos Goutselis, initiator of the study. The investigation showed, "that microplastics are populated in the floor flat-end of mushrooms" and that pathological fungi were enriched in the ground in this way. "Our study therefore justifies the statement that microplastics in the soil is a potential source for fungal infections", so goutselis.
"Numerous pathogenic fungal groups"
Samples were examined from Siaya, a city in the west of Kenya. They were removed on a marketplace, in a courtyard, the strain edge and a waste deposit. "The fact that we have discovered numerous pathogenous fungal groups in the soil samples from Kenya, a clear indication is in general for the urgency of the problem in tropical regions in general, especially since the rate of fungal infections is already high today", Gerhard Rambold explained Professor at the University of Bayreuth and Head of the Mycology Department. It should be urgently offered to prevent plastic mull from being entered into the environment.
Microplastics will also be a great problem for domestic soil. It is amed that they are much stronger with small plastic particles are polluted than the seas, among other things, the ThuNen Institut. Around 13.000 of this can be found in a kilogram of earth – and there is little difference whether the soil samples were taken in the western industrialized countries or in so-called developing policies.
Above all, the dispersion of clear slum contributes to the fact that microplastics reach the field floor. Until a few years ago, these were still considered a dungem in Germany, today they are burned above all above all. In them, heavy metals collect, choke of medicines and plastic particles. About 95 percent of the plastic particles are retained in the clearwares and settle in the clear sludge.
SuperSpreader: Factory-new sports and outdoor fabrics made of polyester
Among other things, plastics get into the wastewater through the wash washing. Scientists of Hochschule Niederrhein had examined in a three-year project, how strong these fibers get into the wastewater during washing. The results were presented in Marz.
About 1.000 times the scientists have washed sports and outdoor textiles, which passed 100 percent polyester fibers. "The by far of highest emissions occur in the first three washes of a textile", Stressed Jens Meyer and Stefan Brandt by the Research Institute Textil and Clothing of the University of Lower Rhine. Up to 850 milligrams of fibrous microplastics per kilogram of textiles are reached over the number of ten washes in the wastewater. Wash washing is only a daily source of microplastics, the strain traffic, the industry and plastic treats and items, cosmetics and shower gels are more. Forecasts ame that around 12 billion tons of plastic mull in the environment are sufficient until the year 2050. The effects are not yet foreseeable.
