Phytotoxicity of the aqueous solutions of some synthetic surfactant-containing dishwashing liquids with and without phosphates

Abstract

The use of synthetic detergents, which include dishwashing detergents, is one of the dangerous factors of environmental pollution. The aim of this study was to investigate evaluate the toxicity of aqueous solutions of surfactant-containing dishwashing detergents according to in accordance with the phytotest using garden cress (Lepidium sativum L.) as a test plant. Dishwashing detergents widespread and purchased in the Ukrainian trading network were investigated as toxicants-water pollutants. The estimation of pollution level was performed on the basis of the characteristics: seed germination energy, seed germination and biometricmorphometric parameters (length of aboveground part and roots of seedlings) with the following statistical analysis. It is having been shown that increasing the concentration of both dishwashing detergents leads to a decrease of germination energy and germination of cress salad seeds. Significant inhibition of the root length and the length of the aboveground part under the influence of both studied liquids was observed.
