Особенности альготестирования проб, содержащих растворенное органическое вещество
Algae tests are widely used due to the availability of cultivation conditions and high reproducibility. Freshwater and marine algae are used to estimate the toxicity of drinking, natural and wastewater, water extracts from soils, sewage sludge and production and consumption waste. The presence of dissolved organic matter in the samples, stimulating the growth of algae and the intensity of chlorophyll fluorescence, can significantly affect the result of algae tests, and therefore on the decision on the presence or absence of a toxic effect. When choosing algae as a test culture to determine toxic effects, it is necessary to take into account the possibility of hyperstimulating the number of cells with dissolved organic matter.
