摘要：With the fast development of nanotechnology,reactive engineered nanomaterials(ENMs)are increasingly discharged into the environment,where they interact with environmental components and organisms and thus pose potential *** interactions-derived formation of nano-environmental and nano-bio interfaces determines environmental behaviors and biological effects of ENMs,and ubiquitous dissolved organic matter(DOM)is bound to impact the interfacial interactions and the resulted environmental ***,we systematically investigated adsorptive interactions between ENMs and various DOM representatives,and thereby demonstrated the effects of DOM on the aqueous suspension/aggregation,mobility in porous media,adsorption of contaminants,transformation,and biological accumulation and toxicity of ***,we conclude that natural DOM can in general expand environmental distribution of ENMs while limit their toxicity to organisms.

摘要：Background:The nanotechnology boom and the ability to manufacture novel nanomaterials have led to increased production and use of engineered nanoparticles(ENPs).However,the increased use of various ENPs inevitably results in their release in or the contamination of the environment,which poses significant threats to human *** recent years,extraordinary economic and societal benefits of nanoproducts as well as their potential risks have been observed and widely *** estimate whether ENPs are safe from the onset of their manufacturing to their disposal,evaluation of the toxicological effects of ENPs on human exposure,especially on more sensitive and vulnerable sectors of the population(infants and children)is *** sources:Papers were obtained from PubMed,Web of Science,and Google *** search words included:"nanoparticles","infants","children","exposure","toxicity",and all relevant ***:A brief overview was conducted to 1)characterize potential exposure routes of ENPs for infants and children;2)describe the vulnerability and particular needs of infants and children about ENPs exposure;3)investigate the current knowledge about the potential health hazards of ENPs;and 4)provide suggestions for future research and regulations in ENP ***:As the manufacturing and use of ENPs become more widespread,directed and focused studies are necessary to measure actual exposure levels and to determine adverse health consequences in infants and children.
