Systemic assessment of pesticide genotoxicity

Изучена генотоксичность более 200 технических продуктов (ТП) пестицидов. Разработан алгоритм оценки эквивалентности ТП оригинальным действующим веществам (ДВ) по критерию «мутагенность». Обоснована необходимость изучения генотоксической активности комбинаций ДВ пестицидов. Установлены ограничения тестов на генотоксичность, обусловленные токсичностью пестицидов разных химических классов. Выявлена зависимость ингибирующего эритропоэз действия триазоловых пестицидов от структуры ДВ. Изучено влияние и предложен общий механизм действия карбендазима на процессы кариокинеза, экструзии ядер и цитокинеза в эритроидных клетках костного мозга млекопитающих. Разработаны критерии экспертной оценки мутагенности пестицидов. The genotoxicity of more than 200 technical grade active ingredients (TGAI) of pesticides has been studied. An algorithm for evaluating the equivalence of TGAIs to the original active ingredients upon the criterion of “mutagenicity” has been developed. The necessity of studying the genotoxic activity of the combinations of pesticide active ingredients was substantiated. Limitations of the genotoxicity tests due to toxicity of pesticides of different chemical classes have been established. The dependence of the erythropoiesis-inhibiting action of triazole pesticides on the structure of the active ingredient was revealed. The effects and the general mechanism of the carbendazim action on the processes of karyokinesis, extrusion of nuclei and cytokinesis in mammalian bone marrow erythroid cells were studied. The criteria for expert evaluation of pesticide mutagenicity have been developed.

Влияние биофунгицидов на развитие возбудителей альтернариоза картофеля

The biological preparations: Planrise, Trychodermin, Phytodoctor on alternaria blight pathogen developing results were proposed. Their inhibiting action were proven by experimental way. The highest inhibiting growing was observed in variant with 10 % solution Planrise and Trychodermin. It was consisted of 25,0 and 29,0 mm, respectively.

Corrosion inhibiting action of Ni–Mo alloy coatings in the presence of mixed metal oxide nanocomposites

Enhanced anti-corrosion properties of Ni–Mo alloy coatings by addition of mixed metal oxide nanoparticles via an electrodeposition method.

Investigation of Inhibitor Polyphosphate Properties for Rotating Steel Disk Electrode in Potassium Nitrate Solution

<p>Inhibition properties of a number of glass-like polyphosphates on 65J steel were investigated using the gravimetry and methods potassium nitrate solution polarization curves in a 0,1M (pH=6,05). The possibilities<br />of optimum experimental conditions were considered as well. Basing on the experimental data the inhibition coefficient and protective effect were found. The inhibiting action of polyphosphates, apparently, is due to the formation of inhomogeneous protecting film on the steel surface.</p>
