Purpose
The objective of the present study was to assess the differences in soil total C and N, microbial biomass C and N, soil soluble organic C and N among eight mono- and mixed species forest ecosystems (18-year-old restoration) in subtropical China. 相似文献8.

Purpose
The structure and dynamics of carbon metabolic process of the soil microbial community in restored forests were dependent on the methods employed in reforestation and subsequent management. To find an appropriate method to restore degraded forests and to assess the ecological benefits of restorations, we studied community level physiological profiles of soil microbial communities in forests in Southern China that were restored by three different methods. 相似文献9.
Purpose
The aim of this study was to assess phosphorus-retention (Pret) capacities via P adsorption (Pads) and desorption (Pdes) by sediments collected from six different sources associated with various origins, physical, and chemical characteristics. 相似文献10.

Purpose
Heavy metal lability, probably, is the most important isolated factor to cause toxicity in plants and organisms in soils. Sorption of heavy metals, in turn, affects directly the amount of their labile forms in soils. Therefore, to assess sorption and quantify labile forms of Cd, Cu, Ni, Pb, and Zn, adsorption and incubation studies were carried out. 相似文献11.

Background, aim, and scope
Contaminated sediments are a worldwide problem, and mobilization of contaminants is one of the most critical issues in environmental risk assessment insofar as dredging projects are concerned. The investigation of how toxic compounds are mobilized during dredging operations in the channel of the Port of Santos, Brazil, was conducted in an attempt to assess changes in the bioavailability and toxicity of these contaminants. 相似文献12.

Purpose
A number of publications have raised trace metal contamination of soils and sediments within and around shooting ranges used for sport or military training. To our knowledge, however, there is no publication on the contamination of sediments derived from military shooting ranges in a marine environment. Therefore, this work was purposed to assess the dispersion and fractionation of ammunition- and bomb-derived trace metals in intertidal sediment. 相似文献13.
Purpose
Organic dyes have been turned into an important emerging type of chemical pollutants with the development of rural textiles, synthetic dye, printing, and dyeing industries and the continuous release from washing fabrics and clothes in recent decades. In order to assess ecological risk of reactive X-3B red dye as a typical dye, the adsorptive and desorptive traits of the dye in soils were investigated and the environmental factors influencing those processes were examined and discussed. 相似文献14.

Purpose
Selective water erosion of soil organic carbon (OC) has been reported to occur in small plots under field and laboratory conditions. However, little is known about how the process of OC erosion happens at larger scales. This study was conducted to assess the differences in the selectivity of OC between different erosion processes taking place within the same catchment. 相似文献15.
Background, aim, and scope
Despite the contribution of many sequential P fractionation schemes to the study of P transformations in agricultural soils, the nature of P in each fraction remains qualitative rather than mechanistic. This study used the sequential extraction and isotopic dilution techniques to assess the recovery of a tracer (32P) in soil P fractions and to elucidate the transformation of soil P in different P pools and its lability. 相似文献16.

Purpose
Sealing of soils prevents the exchange of gas, water and nutrient between soil and other environmental compartments, and affects urban N flux, thereby resulting in certain negative impacts on soil functioning and urban environment. However, little information is available on the biogeochemical cycling and biological activities after sealing of soils in urban areas. The aim of this study was to assess the effects of soil sealing on N transformation and associated microbial properties. 相似文献17.

Purpose
This study uses sediment cores to quantify Holocene sedimentation rates in the Trinity River delta, Texas. An important question is whether modern fluvial sediment input from the Trinity River is adequate to sustain sedimentation in the delta, thereby combating subsidence and further wetland loss. Our objective was to quantify sedimentation rates within the delta in order to assess whether the delta is in- or out-of-phase with modern sediment delivery rates. 相似文献18.

Purpose
UK local authorities are required by environmental regulations to keep a public register of contaminated land. In many towns and cities, there is growing concern of allotment holders about the quality of their allotment soils. Limited information on soil chemistry is available for the southwest of England. This work was carried out to assess whether any allotment and park soil in Bristol could be defined as “contaminated”. 相似文献19.

Purpose
Although organic amendments have been recommended as one of the practices for crop production and soil carbon sequestration, little has been done to evaluate soil organic carbon (SOC) dynamics following long-term application of organic amendments. The objective of this research were to (1) assess the effect of long-term organic amendments on SOC dynamics in rice-based systems; (2) evaluate the relationship between soil carbon sequestration and carbon input based on various mineral and organic fertilization treatments. 相似文献20.
