This thesis deals with ecotoxicity tests of selected substances used in agriculture and horticulture. It is focused on the determination of acute and chronic toxicity of selected herbicides. These herbicides are sold commercially, specifically Finalsan (active substance is nonanoic acid), the product of Neudorff GmbH KG company, and Dominator (active substance is glyphosate, isopropylamine salt) by Dow AgroSciences Ltd. Next tested substances are potassium nitrate and sodium nitrate - common agricultural fertilizers. Potassium dichromate was also tested. Potassium dichromate is very toxic for aquatic environment and it is used as the standard in acute tests. Tests were carried out in terms of effects on aquatic systems, due to very good solubility in water of selected substances. The tests were performed on the organism Daphnia magna.
