  • Ingested nanoparticle safety

    Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance. Writing in a forthcoming issue of the International Journal of ...

  • Nanoparticles decontaminate groundwater

    Since their invention a decade ago at Lehigh University, iron nanoparticles 1,000 times thinner than a human hair have demonstrated an unprecedented ability to clean contaminated groundwater. The palladium-coated particles have remediated more than 50 toxic waste sites in the US and other countries in 10 times faster than traditional pump-and-treat methods. Researchers at Lehigh University have ...

  • Air Monitors launches nanoparticle detector

    Traditional methods for measuring airborne particulate matter measure particle mass per unit air volume, usually with an upper size limit of x microns (PMx etc.). However, from a human health perspective, the particles of most interest are those that penetrate deep into the lungs. For this reason, Air Monitors has launched the Naneos Partector nanoparticle detector in the UK. The Swiss made ...

  • The effects of sunscreen nanoparticles on skin DNA

    A new study indicates that zinc oxide nanoparticles have the potential to cause damage to DNA in human skin cells. These nanoparticles are used as UV filters in sunscreens in many parts of the world, although their use is not yet authorised in Europe (with the exception of one Member State). During the last two years, there has been a rapid growth in the use of nanotechnology, some of which has ...

  • Inhaled nanoparticles can enter the bloodstream

    Studies have found that populations who live in areas with polluted air, containing high levels of combustion-derived nanoparticles (fine particulate matter), are more likely to suffer from respiratory and cardiovascular diseases. This has raised concerns that nanoparticles are to blame and that engineered nanoparticles of a similar size could behave in the same way. It is important, therefore, ...

  • Nickel Nanoparticles Nominated for Listing in Report on Carcinogens

    On September 20, 2013, the National Toxicology Program (NTP) published a Federal Register notice requesting information on 20 substances, mixtures, and exposure circumstances, including nickel nanoparticles, nominated for possible review for future editions of the Report on Carcinogens (RoC). NTP seeks information ...

  • Nanoparticles in the home: more and smaller than previously detected

    Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliances, according to new findings* by researchers at the National Institute of Standards and Technology (NIST). So-called “ultrafine particles” (UFP) range in size from 2 to 10 nanometers. They are emitted ...

  • Engineered nanoparticles: Understanding and managing potential risks

    Nanoparticles may be small, but they are at the centre of a huge debate. Nanotechnology has great potential for industry and society, but we need more awareness of the potential impact of manufactured or engineered nanoparticles on human health and the environment to ensure that its products are safe. Although nanotechnology is new, it is expanding quickly and research is needed to understand its ...

  • testo DiSCmini - The smallest nanoparticle counter in the world

    The Diffusion Size Classifier testo DiSCmini is a handheld sensor for the measurement of nanoparticle number, average diameter and lung-deposited surface area LDSA with a time resolution of up to 1 second (1Hz). The measuring principle is based on electrical charging of the aerosols. The small size of the testo DiSCmini makes the instrument particularly suitable for personal carry-on ...

  • Polystyrene nanoparticles affect fish behaviour and metabolism

    Fish fed polystyrene nanoparticles are less active and show changes to their brains and metabolism, according to a study by Swedish and Danish researchers. The findings suggest that nanoparticles in the environment could have a major impact on fish and aquatic ecosystems. Nanoparticles are increasingly used in consumer products, such as cosmetics, and enter the environment via sewage systems. ...

  • The world’s first model for engineered nanoparticles in surface waters

    Researchers of Wageningen University provide the world’s first spatiotemporally explicit model that simulates the behaviour and fate of engineered nanoparticles (ENPs) in surface waters. Wageningen researcher Bart Koelmans: “This is important in order to assure safe nanotechnology. We do need to have an assessment of the risks of ENPs to man and the environment.” ...

  • Nanoparticles present in residues of waste incineration plant

    The use of nanomaterials in consumer goods is growing, as is their presence in waste. A new study is the first to follow the fate of engineered nanoparticles through the entire waste incineration chain. The results indicate current filter technology is effective in removing nanoparticles from flue gas, but that nanoparticles also bind to residues, such as fly ash and slag, which eventually end up ...
