A study conducted by researchers affiliated with the University of São Paulo (USP) in Brazil has concluded that particles of glitter can hinder the growth of organisms at the base of aquatic ecosystems, such as cyanobacteria (blue-green algae), which play a key role in the biogeochemical cycles of water and soil, as well as being eaten by other organisms. An article on the study is published in the journal Aquatic Toxicology.
A study conducted by researchers affiliated with the University of São Paulo in Brazil has concluded that particles of glitter can hinder the growth of organisms at the base of aquatic ecosystems, such as cyanobacteria , which play a key role in the biogeochemical cycles of water and soil, as well as being eaten by other organisms.
"We found that increasing the amount of glitter raised the biovolume of the cyanobacterial cells and boosted stress to levels that even impaired photosynthesis. The toxicity of glitter for microorganisms has hardly been studied at all. Whatever affects cyanobacteria will indirectly affect other organisms in the same environment," said Mauricio Junior Machado, first author of the article and a researcher in CENA-USP's Cellular and Molecular Biology Laboratory.
