К оценке гумусного состояния и ферментативной активности почв Дальневосточного морского заповедника

Indicators of humus state and catalase activity were determined in the soils of the Far Eastern marine reserve. The average humus content was exposed for the dark humus burozem and the dark humus soil, formed on buried burozem. The distribution of humus in the profile is estimated as gradually decreasing, the humus reserves in the 20 cm layer are characterized as very high and high. Variation of the typical humus composition and humification index differs in the studied soils. "Free" fractions predominate in the composition of humic acids, their proportion reaching high and very high values. The surface horizons of soils are characterized by poor and very poor catalase enrichment. The morphological shape of the profile and the parameters of the humus state of the studied soils of the far Eastern marine reserve confirm the previously obtained data on climate changes and ocean transgression in the South-Western part of the Pacific coast of the region in the Holocene.

Biomonitoring of heavy metals in the southern sector of the Far Eastern Marine Reserve

В 2015 г. изучено содержание металлов в саргассумах южного участка Дальневосточного морского биосферного заповедника. Металлы в макрофитах содержатся в основном в концентрациях фонового диапазона. Долговременные наблюдения за макрофитами (1987, 1996, 1998, 2008 и 2015 гг.) показали, что в настоящее время концентрации Cu, Zn, Cd в водорослях снижаются по сравнению с 19961998 гг., вероятно, в связи с динамикой глобального аэрального переноса загрязняющих веществ. The metals content in Sargassum from the southern area of the Far Eastern Marine Biosphere Reserve in 2015 were studied. Metals in macrophytes are found mainly in concentrations of the background range. Long-term observations of macrophytes (1987, 1996, 1998, 2008 and 2015) have shown that Cu, Zn, Cd concentrations in algae are currently decreasing compared to the period 19961998, probably due to the dynamics of global air transport of pollutants.
