RT Journal Article SR Electronic A1 Švagr, Andrej A1 Kočí, Vladimír A1 Rakovický, Tomáš T1 Toxicological testing of high-salinity samples [in Czech] JF Czech Phycology YR 2002 VO 2 IS 1 SP 107 OP 113 UL https://fottea.czechphycology.cz/artkey/fot-200201-0013.php AB The paper deals with the effect of high salinity on toxicity tests evaluation. In the Czech Republic, there is no legislation to adjust it. However, the question is whether it is needed and if so, which estuarine or marine organisms (algae) would be the most appropriate indicators. Further, species from high-salinity water bodies of arid regions are discussed, as well as a standard marine bioassay (ISO 10253).
