Dispersion paints are mostly used in households for painting walls and ceilings. An interdisciplinary research team from the University of Bayreuth has now analyzed the chemical composition of two typical dispersion paints and discovered a large number of solid particles within them that are only a few micro- or nanometers in size. Studies on biological test systems showed that these particles can harm living organisms.
