- Аннотация: The influence of different types of microplastics (MPs) and ash after burning a mixture of macroplasticsselected in the supralittoral of the Barents Sea on the development of traditional test objects of theculture of the green microalgae Scenedesmus quadricauda and a culture of cladocerans Daphnia magna inchronic experiments has been studied. In terms of the inhibition of algal growth at a concentration of 3 mg/Lof MPs, the PU sample shows the highest toxicity, followed by HDPE (white), HDPE (red), and contact EPSin descending order of toxicity. PP was nontoxic. Ash in the concentration range of 0.01–1000 mg/L does notsignificantly inhibit the growth of Scenedesmus quadricauda. For Daphnia magna, a more expressed decreasein the mean linear size is noted with the addition of intact EPS, and the stimulation of fertility is significantlyhigher in the presence of contact EPS. When comparing the effect of intact and contact PU on D. magna, thedeath of all individuals under the influence of intact PU is found; when adding PU, survival remained at thecontrol level. MP particles and ash affect the trophic activity of daphnia when fed with chlorella, but thiseffect does not lead to changes in fertility and growth during long-term observation.
