The work considers the morphological structure of sandy loam gleyic rzhavozems in the background area and at the site of an oil spill on a field in the northeastern part of Sakhalin Island. Correlations between the total content of oil hydrocarbons (OHCs) in the horizon AY and its color parameters measured using the Munsell, RGB, and Lab systems are revealed. Linear regression equations are presented. Signs of technogenic impact in the top horizons of the rzhavozems at various levels of oil contamination are presented. 相似文献

We have analyzed the radioecological conditions of the Chashnikovo Training and Experimental Soil Ecology Center (TESEC) of Moscow State University in the Solnechnogorsk district of Moscow oblast. We have estimated the rate of soils, plants, air layer near the soil surface, and soil air by the main natural and technogenic radionuclides evaluated. It is shown that the area is radiation-safe with respect to the main parameters. 相似文献

A comparative study of chemical properties of soils under wood plants (pine, oak, and birch) and agrocenosis was performed. The profile distribution and spatial heterogeneity of \(pH_{H_2 O} \), pHKCl, total acidity, and exchangeable Ca2+ and Mg2+ in soils were described. Soil acidity conditions were characterized using discriminant analysis and principal components analysis. 相似文献

Thermal structure measurements obtained by the two VEGA balloons show the Venus middle cloud layer to be generally adiabatic. Temperatures measured by the two balloons at locations roughly symmetric about the equator differed by about 6.5 kelvins at a given pressure. The VEGA-2 temperatures were about 2.5 kelvins cooler and those of VEGA-1 about 4 kelvins warmer than temperatures measured by the Pioneer Venus Large Probe at these levels. Data taken by the VEGA-2 lander as it passed through the middle cloud agreed with those of the VEGA-2 balloon. Study of individual frames of the balloon data suggests the presence of multiple discrete air masses that are internally adiabatic but lie on slightly different adiabats. These adiabats, for a given balloon, can differ in temperature by as much as 1 kelvin at a given pressure. 相似文献

The VEGA balloons made in situ measurements of pressure, temperature, vertical wind velocity, ambient light, frequency of lightning, and cloud particle backscatter. Both balloons encountered highly variable atmospheric conditions, with periods of intense vertical winds occurring sporadically throughout their flights. Downward winds as large as 3.5 meters per second occasionally forced the balloons to descend as much as 2.5 kilometers below their equilibrium float altitudes. Large variations, in pressure, temperature, ambient light level, and cloud particle backscatter (VEGA-1 only) correlated well during these excursions, indicating that these properties were strong functions of altitude in those parts of the middle cloud layer sampled by the balloons. 相似文献

The contents and profile distributions of Cr, Ni, Cu, Zn, Cd, Hg, Pb, and benzo[a]pyrene in oligotrophic peat soils, oligotrophic peat gley soils (Dystric Fibric Histosols), humus-impregnated peat gleyzems (Dystric Histic Gleysols), and mucky gleyzems (Dystric Gleysols) have been analyzed with consideration for their degree of oligotrophicity and anthropogenic loads. Horizons with the accumulation (O, Tpyr, TT) and removal (Ghi,e) of heavy metals have been revealed. The increase in the content of heavy metals and benzo[a]pyrene in the upper layer of oligotrophic peat soils under technogenic fallouts in the impact zone of flare and motor transport has been considered. Statistical parameters of the spatial variation of parameters in organic and gley horizons have been calculated. The variation coefficients of pollutant elements (Pb and Zn) in the surface horizons of soils increase to 100–125%. Positive correlations revealed between the content of some heavy metals in litter indicate their bioaccumulation and possible joint input with aerotechnogenic fallouts. No correlations are found between the contents of benzo[a]pyrene and heavy metals, but a reliable negative correlation with the ash content is noted in the peat horizon. 相似文献

The vertical and lateral microvariability of total petroleum hydrocarbon (TPH) in technogenic soils is considered in this work. An autocorrelation and cross-correlation analysis of the TPH along a transect in the lateral direction is carried out. Statistical parameters of TPH for various industrial sites, oil spills, and natural exits are described and the normal or lognormal law of distribution of petroleum hydrocarbons in technogenic soils is confirmed. The percentage of the total spatial variability of TPH contributed by hierarchical sampling levels (10 cm, 0.25 ha, and 20 km2) is estimated. Planning the volumes of the samples that are necessary for an assessment of the average level of pollution in soils for separate sites and the entire territory of the oil field is carried out. 相似文献

The results of vertical and lateral intrasoil migration of oil hydrocarbons (OHCs) in podzolic, techno-podzolic, brown forest,
alluvial meadow-bog, and peat gley soils of Sakhalin Island are presented in this article. An estimation of the spatial distribution
of oil hydrocarbons on the surface of oil spills, industrial sites, and natural discharges of oil is made. The factors influencing
the structure of contamination halos and migration intensity of oil hydrocarbons in soils are considered. 相似文献
