Phytotoxicity of a synthetic polymeric surfactant.What is new: a polymeric chemical inhibited growth rate of plant seedlings

The first publication to report phytotoxicity of a synthetic polymeric surfactant. An innovative bioassay with the higher plant Fagopyrum esculentum (buckwheat) was carried out. A negative reaction of buckwheat seedlings to pollution of the aqueous medium with a polymeric surfactant was discovered.

Abstract

The reaction of buckwheat cv. Shatilov-5 seedlings to pollution of the aqueous medium with polymeric surfactants - a copolymer of hexene and maleic aldehyde (CHMA), was investigated. It was shown that CHMA content in water with a concentration of the active substance of 0.4-0.9 mg/ml inhibited plant growth. The effect was shown with prolonged incubation of germinating seeds for 43-67 h or more. These data should be taken into account in analyzing the possible ecological consequences of irrigating lands with waste waters and polluted waters.

Inhibitory and stimulation effects of a synthetic surfactant on two unique strains of the ocean species of cyanobacteria

This is a first publication to report both inhibitory and stimulation effects of a synthetic surfactant on two unique strains of the ocean species of cyanobacteria Synechococcus from the collection of WHOI (U.S.A.). These data demonstrated a new hazard of an imbalance of species composition of marine phytoplankton under the effect of pollution by synthetic chemical pollutants.

Abstract
The non-ionogenic surfactant Triton X-100 acted differently on cyanobacteriaSynechococcus WH 7805 and WH 8103: 5 mg/liter of the surfactant inhibited strain 7805 and favored the development of strain 8103. A lower concentration (0.5 mg/liter) stimulated the growth of both strains. Triton X-100 produced no effect on the motility of strain 8103 cells.
