Abstract
Danio rerio is widely used as a model object for various scientific studies, including environmental ones. In addition to assessing the survival of individuals and other research methods, the method of histological bioindicators is very indicative in toxicological experiments. As such markers, the liver and gills of fish were used in this work, which, when exposed to the substance under study, changed their structure, allowing us to judge the degree and nature of this effect. The present study examined the effects of potassium sulfate in concentrations from 100 to 1000 mg/l on the organs of danio. It was revealed that the negative effect of the substance on the gills of fish is mainly expressed in hyperemia and hyperplasia of the respiratory epithelium, and pathological changes in the liver are represented by both fatty embolism and damage to the liver tissue (ruptures, replacement with connective tissue). At the same time, the reaction of the organs was noted when exposed to the minimum of the studied concentrations — 100 mg/l.
