“…A further increase in REE doses led to a significant increase in toxicity indices. Greater sensitivity of ciliates compared to bacteria to aluminum salts in natural water was shown earlier [Olkova and Berezin, 2021]; thus, increased sensitivity of ciliates to REE can be called natural.…”

The purpose of the work was to compare the sensitivity of autotrophic and heterotrophic organisms used in bioassay to lanthanum and cerium under the conditions of a model experiment with aqueous media. Using bioassay methods, the pre-lethal effects of La and Ce in heterotrophic Paramecium caudatum and Escherichia coli, as well as autotrophic Chlorella vulgaris and Nostoc linckia were determined. Model solutions of La 2 (SO 4 ) 3 •8H 2 O and Ce 2 (SO 4 ) 3 •8H 2 O were tested in the concentration range of 0.1-200 mg/l. As a result, it was shown that heterotrophic organisms are more sensitive to water pollution with La and Ce than autotrophic ones. According to the totality of experiments, cerium turned out to be more toxic than lanthanum. When planning the environmental studies of wastewater or reservoirs polluted with REE, it is recommended to focus on comparative sensitivity of bioassay methods, taking into account the test-functions used: bioassay for chemotaxis of P. caudatum > bioassay for changes in bioluminescence of E. coli (strain M-17) > bioassay for the content of chlorophyll а and intensity of lipid peroxidation in N. linckia > bioassay on the increase in the number of Cl. vulgaris.

“…At present, biotests were applied either for the detection of the effects of a particular chemical agent under laboratory conditions (Nałęcz-Jawecki et al 2010) or to assess the overall toxicity of material taken from the environment (Chial et al 2003, Latif and Licek 2004, Czerniawska-Kusza et al 2006, Blaise and Ferard 2006, Fai and Grant 2010, Palma et al 2010, Torokne and Toro 2010, Heisterkamp et al 2021, Szara-Bąk et al 2021, Szklarek et al 2021. Several studies focused on the relationships among the chemical composition of environmental samples or model laboratory mixtures and their effects revealed in biotests (Kahru et al 1999, Olkova andBerezin, 2021). In other research, biotest results were compared with chemical analyses in highly contaminated environmental matrices such as wastewaters (Manusadzianas et al 2003, Czerniawska-Kusza et al 2006, Cloete et al 2017, Zgórska et al 2020.…”

“…Bioassays are a useful tool for ecological risk assessment of the level of sediment contamination [48][49][50][51]. They are a good addition to chemical analysis, as they thoroughly describe the accumulation of toxic elements in sediments as well as their bioavailability and interaction [52][53][54].…”

The Kosva Bay is permanently affected by acid mine drainage (AMD) from Kizel Coal Basin in the Perm Krai of Russia. This discharge is released in the middle part of the Kosva River from the abandoned mines. This study investigates the current trace element (TE) concentrations for Zn, Cu, Pb, Ni, Cr, Cd, As, and Hg and the mineral composition, major oxides, grain size of sediments, and acute toxicity using two test organisms within the site of AMD downstream from the Kosva River and up to the Kosva Bay of Kama Reservoir. The objectives of this study were to analyze the quality of sediment and level pollution of Kosva Bay using pollution and ecotoxicological indices. The environmental indices, namely the contamination factor (CF), the geoaccumulation index (Igeo), and the potential ecological risk factor ( indicate contamination by Cr and Pb in sediments at the site of AMD, with the highest values for Cr, Cu, and As in the Kosva Bay sediments downstream of abandoned coal mines. The results of Igeo and CF average values in bay of sediments showed different degrees of contamination, from moderate contamination to considerable contamination, respectively. According to the potential ecological risk index (RI) values, the Kosva Bay sediments exhibited low to moderate risk, and As and Cd have the highest contribution rate. According to LAWA and the Polish geochemical classification of sediments, sediments of the bay correspond to the highest levels (IV–III classes) for Cr, Ni, and Hg. Based on the SQGC, Hg, Cd, Cr, and Ni are the most probable for resulting in adverse effects on aquatic organisms in this study. The results of this study indicate that complex pollution and ecotoxicological indices must be supported by ecotoxicologal tests. High precipitation totals, low evaporation rates, and flow regulation stream by the Shirokovsky Reservoir located upstream from abandoned coal mines provide significant fluctuations in streamflow, which is probably the most important factor controlling the distribution and mobility of TE in the studied sediments.
