- Аннотация: Bioassay is a popular method for assessing the ecotoxicological state of different components ofurban ecosystems: soils, water bodies, and air. However, little is known about the potential of bioassay application to determine the ecotoxicity of urban dust, which is a complex heterogeneous medium composed ofnatural and technogenic particles. Many components of urban dust are known to have toxic effects on livingorganisms. The purpose of this paper is to review the existing practices for assessing the ecotoxicity of urbandust and identifying the key trends in the development of the bioassay method. Analysis of the existing studieshas revealed a high potential of bioassay methods, since they are sensitive to a wide range of pollutants thatare contained in dust and can selectively reflect dust toxicity depending on environmental factors and beimplemented using organisms of different trophic levels. The following dust characteristics should be takeninto account for proper choice of the bioassay method: sample weight, wettability, pH, and content of watersoluble ions and organic matter. Due to the complexity of the composition of urban dust and different potentials for the transition of its components into water extracts, it is recommended to prioritize contact bioassaybased on solid dust substrates instead of extracts. For comprehensive assessment of dust impact on an urbanecosystem, it is reasonable to test a set of organisms of different trophic levels. Standards should be developedfor dust bioassay to unify the results of different studies. One of the most important methodological questionsis the choice of the control sample.Keywords: ecotoxicological assessment, algae, high
