Nanotechnology or the existence of great hazards affecting the environment and human health

nanotechnology has attracted widespread media attention since the day it was bornUp to now, the sales channels have reached hundreds of nano-productsHowever, a report published in the British journal Nature Nanotechnology said on the 25th, unlike the general public's positive attitude towards the technology, scientists are concerned about the potential impact of nanotechnology on humanhealthand ecological environment" The default "Riskreport surveyed 363 nanotechnology scientists, engineers and 1,015 non-professionals by telephone across the United StatesThe findings show that while scientists agree that their nano-research will lead to breakthroughs in the fields of medicine, environmental protection and national defense, they have serious concerns about the risks that nanotechnology could pose to the environment and human health"Scientists don't say there's a problem with nanotechnology," said the report's lead author, Dijatram Schaefer, a professor at the University of Wisconsin-MadisonThey said, 'I don't knowThe study is not yet complete'
One nanometer is one billionth of a meterNanotechnology can be used to produce new antimicrobial materials, microprobes that collect patient cell samples, and more powerful computers and laser equipmentNanomaterials are lighter and stronger than any other material that has been widely used, and promise to bring about changes in automotive and aircraft manufacturing, garment making, robotics and other fieldsNanoproducts have been developed, including golf clubs, tennis rackets and antibacterial food storage containers The survey found that 20 per cent of scientists surveyed were concerned that nanotechnology could pose a new form of pollution to the environment, while only 15 per cent of non-professional respondents held the same view More than 30 percent of scientists are concerned about the risks nanotechnology could pose to human health; Media misinformation Schaeuble says there has been a discussion of the risks of nanotechnology within the scientific community, but it is because of the lack of substantive progress in the relevant research At the same time, the media is touting the future of nanotechnology, downplaying its risks, which can mislead the public While the specific harm seisuing human health and the environment from nanotechnology is uncertain, researchers are examining each possibility, such as how nanoparticles are sucked into the lungs and whether nanomaterials are toxic The findings suggest that scientists are more concerned about nanotechnology than other technologies When nuclear and genetically modified food technologies emerged, scientists were also more concerned about the risks of these technologies than the public However, scientists seem limited in their ability to communicate with the public Nanoexperts hope to explain the technology's risks to the public before it is widely used, Schaefer said Because of the advent of nuclear technology and genetically modified foods, the public was initially feverish, but grew increasingly worried about the risks of the accidents or exposed incidents that followed " Nanotechnology may be the first emerging technology that requires scientists to explain to the public why they are more concerned about its risks Shoifere said
