Content of biogenic micro-and macronutrients (Zn, Co, Cr, Na, Ca, Fe) in the eutrophic peat deposit

Методом нейтронно-активационного анализа охарактеризованы торфы и болотные воды месторождения Таган (Томский район, Томская область) на содержание биогенных макро- (Na, Ca, Fe) и микроэлементов (Zn, Co, Cr). Анализ образцов с нескольких пунктов наблюдений, различающихся по ботаническому составу и гидротермическим условиям залегания, показал, что элементный состав торфов характеризуется региональными особенностями и ботаническим составом. Концентрации элементов по глубинам трех пунктов наблюдений изменяются синхронно, что свидетельствует о типичности условий накопления этих элементов. Среднее содержание микроэлементов в изучаемой торфяно-болотной экосистеме сопоставимо со средними значениями данного региона. The concentration of biogenic macro- (Na, Ca, Fe) and microelements (Zn, Co, Cr) in peat and bog waters of the Tagan Deposit (Tomsk District, Tomsk Region) was determined by neutron activation analysis. Analysis of samples from several observation points which differ in botanic composition and hydrothermal mode of occurrence showed that the amount of various elements in peat is determined by regional characteristics and botanical composition. From comparative elements concentration analysis, it has been found that concentration of elements varies identically depending on the depth of the peat bog, which indicates typical conditions for the accumulation of these elements. The average concentration of trace elements in the studied peat-bog ecosystem is comparable to the average values of this region.

Peats and marsh waters of the peat bog eutrophic ecosystem (Tomsk region) for the content of trace elements have been studied. The peat deposit is composed of lowland peats of grass type predominantly. The deposit average depth is about 3 meters. Samples of several observation points, which differ in botanical composition and hydrothermal conditions of occurrence were analyzed. The concentration of biogenic (Zn, Co, Cr), alkaline (Rb, Cs), alkaline earth (Sr, Ba) and rare earth (Hf, La) metals in peat and marsh waters has been determined by the method of neutron activation analysis. It was shown that the amount of various elements in peat is determined by regional characteristics and botanical composition. From comparative elements concentration analysis, it has been found that concentration of metals varies identically depending on the depth of the peat bog, which indicates typical conditions for the accumulation of these elements. As a result of the research was founded high content of the Ba and Sr in peats of all observation points. It has been established that the peat of native section 3 is enriched with all studied metals Zn, Cr, Sr, Ba in comparison with peats of the first and the second observation points. Besides, under the conditions of this ecosystem cobalt, rubidium and lanthanum were accumulated in peats. The average concentration of trace elements in the studied peat bog ecosystem is comparable to the average values of this region. We have found that samples of marsh water are enriched with the biogenic zinc. Among rare metals, such elements as strontium and barium are the most abundant in marsh water, what correlates with the largest content of Zn, Sr and Ba in the studied peats. Light Rb and Sr ions transfer from peat to swamp waters in greater amount than heavier Cs and Ba ions. Strontium enters and migrates intensively to the swamp waters of all three observation points.

SummaryMany methods have been advocated for the determination of the origin of opium, but so far no research has been reported on the possibilities of such studies by means of radiochemical methods applied to the opium ash.In the present investigation the gold and lanthanide content in samples of opium ash has been studied using neutron activation analysis. The gold content was found to vary from about 0,5 to 10 ppm and the total rare earths content from about 20 to 150 ppm. Large variations are found in the distribution pattern of the individual rare earths in opium samples from different origin. The results are discussed and indicate that activation analysis may be used to indentify the origin of opium samples.
