Sažetak
Pollution by microplastics, i.e. particles smaller than 1 mm, is an environmental problem because these particles are detected in all environmental components. One of the sources of microplastics are cosmetic products where microplastics, called microbeads, are used as abrasives. In latest years, the use of microplastics in cosmetics have been limited and these abrasive materials have been replaced by various materials e.g. by microcrystalline cellulose and other materials that have not been yet tested for possible adverse effects. In this context, the ecotoxicity of polyethylene microplastics and microcrystalline cellulose particles extracted from a cosmetic product was tested by using duckweed Lemna minor growth inhibition test. The experiment was performed in 100 mL beakers containing 50 mL Steinberg medium, Lemna minor and polyethylene microplastics or microcrystalline celluloses particles (100 mg/L). The experiment was performed in a climate chamber at 24 ± 2 ºC and high humidity (> 70%) with a photoperiod of 16/8 h (light/dark) during an exposure time of 7 days. The effects of both particles on specific growth rate, root length and chlorophyll content were monitored. The bioaccumulation of particles on Lemna minor biomass was also investigated. Results showed no significant effects of both particles on specific growth rate and chlorophyll contents, but microcrystalline cellulose particles affected the root length of Lemna minor and accumulated on plant biomass in higher quantity in comparison to polyethylene microplastics.
