Nanoparticles 'safe for soil bugs'

At last, some good press for nanomaterials. Ronald Turco at Purdue University in West Lafayette, Indiana, and his colleagues have found that fullerenes, nanoscale carbon spheres, do not harm microbes when released into the soil. Their study is the first of its kind to focus on soil microbes, which play a key role in recycling nutrients used by plants. “The early evidence suggests nanomaterials, at least fullerenes, are being absorbed by the soil and are not a problem,” says Turco. Previous studies have shown that nanoparticles can scar lung tissue and inhibit microbial behaviour in water. Some fear such “nano-pollution” could cause significant damage to the environment and people’s health. Journal reference: Environmental Science & Technology (DOI:
