NEW EXAMPLE OF USE OF LENS CULINARIS FOR PHYTOASSAY OF ECOTOXICITY OF CHEMICALS

Abstract

Previously, toxicity of some synthetic detergents (including laundry detergents) to the plant seedlings of several species of terrestrial higher plants was discovered in research conducted at Moscow University by S.A.Ostroumov. A new example of toxicity of a laundry detergent to plant seedlings was found in this study. The synthetic detergent tested, namely the liquid laundry detergent (LLD) “Blue Moon”, which was manufactured by Blue Moon Group Co, Ltd (Guangzhou, China), produced noticeable phytotoxic effects on the plant seedlings of the terrestrial higher plant Lens culinaris. This detergent at the concentrations 0.5 % - 1% induced a pronounced decrease in the average root length of the seedlings of Lens culinaris. The concentration 5% was lethal to Lens culinaris.
