Yu.N. Terentyev, N. V. Syrchina, N.N. Bogatyryova, T.Ya. Ashikhmina, A.V. Sazanov, M.L. Sazanova, V.N. Pugach, V.A. Kozvonin & A.A. Burkov
The development of new forms of nitrogen-containing mineral fertilizers comporting with world safety standards is currently quite a relevant problem. Existing forms of combined fertilizers including ammonium nitrate and carbonates have a number of disadvantages (hygroscopicity, caking, partial ammonium nitrogen decline). Therefore active search of new components with certain advantages is conducted. At the same time, their inclusion into the fertilizers’ composition should ensure a high level of plants’ nitrogen assimilation, exclude environmental pollution and...

Biosorption of heavy metals by micromycetes: specificity of the process, mechanisms, kinetics

S.G. Skugoreva, G.Ya. Kantor & L.I. Domracheva
One of the ways to remove heavy metal (HM) compounds from the environment is biosorption. Most studies on biosorption are carried out on microorganisms, among which micromycetes occupy leading positions. They have a high degree of adaptation and resistance to the action of HM, are able to accumulate and transform HM compounds, show high sorption activity in relation to them. A feature of the cell wall of micromycetes is the predominance of polysaccharides (in particular,...

Pectic polysaccharides of callus tissue of the stem of Heracleum sosnowskyi Manden.

E.N. Gordina, A.A. Zlobin, E.A. Martinson & S.G. Litvinets
The uncontrolled growth of Sosnovsky’s hogweed (Heracleum sosnowskyi Manden.) in the central regions of the Russian Federation is a pressing problem, because areas occupied by this plant significantly increase each year. The methods used for the destruction of Sosnovsky’s hogweed (mowing, the use of herbicides, the use of geotextile, etc.) are not effective enough, because the hogweed seeds remain viable for a long time, and its roots penetrate deep into the soil. These methods do...

В работе описана возможность использования спутниковых снимков среднего пространственного разрешения с космического аппарата Sentinel-2 для идентификации участков массового роста борщевика Сосновского (Heracleum sosnowskyi Manden.). Для дешифрирования космических снимков использовали вегетационные индексы NDVI и ClGreen. Расчётные индексы позволили выделить на снимках типы растительности, представляющих значительную часть растительных сообществ Кировской области (лиственные и хвойные породы, луговая растительность), а также моносообщества борщевика Сосновского. Применённый в работе подход к дешифрированию космических снимков показал, что вегетационные индексы ClGreen и NDVI...

Переработка отходов фторопластов в ультрадисперсный политетрафторэтилен для получения смазок и защитных покрытий

С.Л. Фукс, С.В. Хитрин & С.В. Девятерикова
Образование до 50% отходов при производстве и потреблении фторопластов приводит к накоплению в окружающей среде политетрафторэтилена (ПТФЭ), неспособного к безопасной деструкции в природных условиях. Чрезвычайно актуальна эффективная переработка отходов ПТФЭ без выделения опасных веществ. В работе определены состав и структура летучих и твёрдых высокомолекулярных продуктов, образующихся при переработке отходов ПТФЭ методами предложенной нами термодеструкции с исчерпывающим фторированием (Ф-4 и Ф-4Д) и гидротермальной деструкции (Ф-4). Летучая фаза, выделяющаяся при переработке отходов Ф-4Д методом термодеструкции с исчерпывающим...

I.A. Zyryanov, A.P. Pozolotin, A.G. Budin & E.V. Kantor
Electric power generation based on combustion of organic fuel is one of the largest sources of air pollution by toxic substances, including products of incomplete combustion. To reduce the negative impact of power plants on the environment, various methods are used to optimize the regimes for burning fuel and cleaning the emissions of combustion products into the atmosphere. One of the promising ways to regulate the combustion of fuels in order to reduce emissions is...

Electrochemical obtaining of nickel hydroxide from nickel plating waste water for application in the alkali secondary cells

V.L. Kovalenko, V.A. Kotok & V.V. Malyshev
The rinsing and waste water of the plating industry, containing the heavy metal cations, are the source of environmental pollution. Nickel cations have a strong biological hazard. At the same time, up to 30% of nickel compounds spent on nickel plating are irretrievably lost to the rinsing water. Purification of the rinsing and wastewater from heavy metal cations is expensive. It’s economically effective to develop the methods of local treatment of plating rinsing water with...

Впервые проведена оценка состояния городских почв вблизи одной из автомоек г. Кирова с использованием различных методов физико-химического, микробиологического анализа и фитотестирования. Полученные данные свидетельствуют о высоком уровне загрязнения почв нефтепродуктами, содержание которых превысило условно фоновое значение в 27–173 раза. Токсический эффект исследуемых урбанозёмов проявился в снижении каталазной активности, видового разнообразия фототрофов, диаметра колоний азотобактера, увеличении фитотоксичности по отношению к растениям ячменя и резком снижении численности живых клеток в популяции цианобактерии Nostoc paludosuт. Между данными показателями...
