Abstract—The effects of the non-ionogenic surfactant, Triton X-100 (TX), on the growth of cultured centric diatom Thalassiosira pseudonana were studied. In the presence of 0.1 mg/l TX the cell density in the culture was markedly lower than in the control culture. In the presence of 1 mg/l TX the decrease in cell density exceeded 50%. The decrease in the specific growth rate was about 10% in the presence of 0.1 mg/l TX and about 40% in the presence of 1 mg/l TX (over a period of seven days). The diatom sensitivity to TX was higher than that of some red and green algae and chrysophytes, as well as that of starfish spermatozoa and plant seedlings
to TX or similar surfactants. These data reveal some more aspects of the ecological danger of aquatic pollution by non-ionogenic surfactants.

Publication 2.
This paper is the first publication that reported the concentrations of a number of rare earth elements in biodetritus. The rare earth elements are a key component of modern hi-technology products and they are a new component in the modern solid wastes and waste waters. This paper is an innovative and significant contribution to the database for modern environmental monitoring.
**
Biodetritus that formed over a 7-month period in microcosms with Viviparus viviparus, Unio pictorum , and Ceratophyllum demersum contained a number of elements. This is the first study to determine concentrations of some elements in biodetritus. Neutron activation analysis showed that the elements concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se > Nd > La > U > Hf > Sb > Th > Sm > S > Cs > Au. The data obtained contribute to understanding of the multifunctional (polyfunctional) role of aquatic organisms in aquatic ecosystems.

What is new, a 2-line summary: this is the first paper to report hazardous effects of a widely-used chemical on diatom algae, important component of phytoplankton.
This is a first publication to report a hazardous effect of a synthetic non-ionic surfactant (exemplified by Triton X-100) on diatom algae (exemplified by a marine species, Thalassiosira pseudonana). In the paper, it was shown that this chemical inhibited the reproduction rate and abundance of the cells of this species of marine phytoplankton. Non-ionic surfactants are the key components of many detergents and other chemical mixture products that are being produced in big quantities and used on large scale.

Abstract—The effects of the non-ionogenic surfactant, Triton X-100 (TX), on the growth of cultured centric diatom Thalassiosira pseudonana were studied. In the presence of 0.1 mg/l TX the cell density in the culture was markedly lower than in the control culture. In the presence of 1 mg/l TX the decrease in cell density exceeded 50%. The decrease in the specific growth rate was about 10% in the presence of 0.1 mg/l TX and about 40% in the presence of 1 mg/l TX (over a period of seven days). The diatom sensitivity to TX was higher than that of some red and green algae and chrysophytes, as well as that of starfish spermatozoa and plant seedlings
to TX or similar surfactants. These data reveal some more aspects of the ecological danger of aquatic pollution by non-ionogenic surfactants.

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. These data demonstrated a new hazard of an imbalance of species composition of marine phytoplankton under the effect of pollution by synthetic chemical pollutants.
The non-ionogenic synthetic surfactant Triton X-100 acted differently on two strains of cyanobacteria Synechococcus WH 7805 and Synechococcus WH 8103. Thus, 5 mg/liter of the surfactant inhibited the growth of the culture of strain 7805 and favored the growth of the culture of strain 8103. A lower concentration (0.5 mg/liter) stimulated the growth of both strains. The surfactant Triton X-100 produced no effect on the motility of strain 8103 cells.

What is new, one-line summary: 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 (cv. Shatilov-5) seedlings to pollution of the aqueous medium with a polymeric surfactant was discovered. The surfactant studied was a copolymer of hexene and maleic aldehyde (CHMA). 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 analysis of the possible ecological consequences of irrigating lands with waste waters and polluted waters.

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. At a concentration of "Vilva" 0.25 ml / L, the growth of the seedlings of F. esculentum stopped, and the elongation rate of the seedlings of O. sativa was inhibited by 22-75%.

The content of this paper was described at this site as following:
Description: Based on the development of root hairs in seedlings of Fagophyrum esculentum, Sinapis alba, and Triticum aestivum, and surfactant Triton X-100 was bioassayed. Triton X-100 induced a loss of adherence to the substrate of F. esculentum and S. alba seedlings. It inhibited the development of root hairs in these species and also in T. aestivum. The new approach to bioassay of xenobiotics and pollutants is discussed.

This is 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 chemical: the methods that use (1) plant seedlings; (2) aquatic algae cultures; (3) soil algal cultures.
Experiments investigating the effects of the cationic surface active compound tetradecyl trimethylammonium bromide (TDTMA) on a number of aquatic and soil algal cultures, and the seedlings of the higher plant Fagopyrum esculentum are described, and the results presented. It is concluded that future studies on the effects of pollutants on algae should involve the use of several test systems (both aquatic and soil algal cultures).

A short abstract: Experiments investigating the effects of the cationic surface active compound tetradecyl trimethylammonium bromide (TDTMA) on aquatic and soil algal cultures and the seedlings of Fagopyrum esculentum are described. The experimental results are presented. It is concluded that the future studies on the effects of pollutants on algae should involve the use of several test equations.
A more detailed abstract: The effects of environmental pollution with a cationic surface-active substance (surfactant tetradecyltrimethylammonium bromide TDTMA) on certain cyanobacteria and algae were studied. The effects on cyanobacteria Nostoc muscorum Ag, strain 33 isolated from the soil in the Kirov Oblast (Region); and on green algae Bracteacoccus minor (Chodat) Petrova, strain 200 and strain 219 (the strain 219 was isolated from the volcanic ash collected next to Tyatya Volcano, the island of Kunashir) were investigated. Their sensitivity to the surfactant TDTMA was compared with the sensitivity of terrestrial plants. The algal experiments were performed with aquatic and soil cultures. The experiments with terrestrial plants used the earlier-developed method with the seedlings of Fagopyrum esculentum Moench. The experiments revealed a higher sensitivity of the test with the aquatic algal cultures.
