Do nanoparticles affect the health of the soil ecosystem?
New research reveals that many microorganisms, including bacteria and protozoa, show little sensitivity to fullerene nanoparticles applied to soil samples. However, fast-growing bacteria decreased in number and the genetic diversity of bacteria and protozoa altered slightly. This could affect the bottom of the food chain, which may have long-term implications for the overall health of the soil ecosystem. Nanotechnology collectively describes technology and science which utilises nanoscale particles. Despite their benefits, introduction of nanoparticles into the environment might have significant impacts as they may be extremely resistant to degradation and have the potential to accumulate in bodies of water or in soil. The study observed the behaviour of C60 fullerenes, also know as ‘Bucky Balls’, in soil. These are a type of carbon nanomaterial currently used in some cosmetics with expected future use in pharmaceuticals. Other types of carbon nanomaterials have a promising future for
