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.
