Juxtaposition of results of the three methods of assessment of toxicity of a new pollutant: the methods that use plant seedlings, aquatic algae and soil algae

A first publication to report a unique bioassay of synthetic surfactants using soil algae. Also, this is a first publication to report a juxtaposition of results of the three methods of assessment of toxicity of a surfactant: the methods that use (1) plant seedlings; (2) aquatic algae cultures; (3) soil algal cultures.

Abstract
New previously unknown facts on toxicity and environmental hazards of a synthetic cationic surfactant (surface active substance, surface active agent) were discovered and are presented in this article.
Experiments investigating the effects of the cationic surface active compound tetradecyl trimethylammonium bromide (TDTMA) on aquatic and soil algal cultures as well as the seedling of the higher plant, buckwheat Fagopyrum esculentum are described and the results presented. It is concluded that future studies on the effects of pollutants on plants should involve the use of several test systems.

New method to bioassay chemicals

A discovery of a new method for testing toxicity of chemicals. This method is especially useful to find and characterize phytotoxicity of chemicals. This method proved to be also useful to find new facts on environmental hazards of chemicals and chemical pollution of environment. Using this method a discovery was made of a new important examples of phytotoxicity of synthetic organic chemicals, exemplified by some synthetic surfactants.

Abstract

The authors discovered that the development of root hairs in plant seedlings can be used as a test for potential toxicity of chemicals. The seedlings of Fagophyrum esculentum, Sinapis alba, and Triticum aestivum were used. The synthetic surfactant Triton X-100 was bioassayed. Triton X-100 induced a loss of adherence to the substrate of the F. esculentum and S. alba seedlings. Triton X-100 inhibited the development of root hairs in the seedlings of these species as well as in the seedlings of T. aestivum. This is a new approach to bioassay xenobiotics and pollutants as exemplified by synthetic surfactants.

New phytotoxic effects of a liquid detergent

The first paper to report new phytotoxic effects of a liquid detergent. Before this paper, no phytotoxic effects of liquid detergents were known. New phytotoxic effects of the liquid detergent "Vilva" on the seedlings of the higher plants, buckweat Fagopyrum esculentum and rice Oryza sativa, were discovered.

Abstract
In the paper, bioassay of a liquid detergent Vilva was reported. New negative effects of the detergent Vilva on the elongation rate of the plant seedlings of Fagopyrum esculentum and Oryza sativa were found. Under the effect of the detergent, the elongation rate was inhibited.
