- Abstract:
- ... Superabsorbent polymer (SAP) is an eco-friendly material in soil and water conservation, agricultural production, and the performance enhancement of cement-based materials. It is well known that moisture migration and accumulation is a prerequisite for the performance deterioration of soil. In this study, SAPs were introduced as an admixture for soil expecting to enhance its ability of accommodati ...

- Abstract:

While the degradation may mobilize previously protected material from the permafrost profile, little is known about the stocks and stability of mercury (Hg) in the QTP permafrost. Here we measured total soil Hg in 265 samples from 15 permafrost cores ranging from 3 to 18 m depth, and 45 active layer (AL) soil s ...

- Abstract:
- ... Many different methods have been proposed to determine aggregate stability. In most of these methods, certain aggregate size is used to estimate the aggregate stability of the whole soil. Determination of aggregate stability on a certain aggregate size is insufficient to represent the aggregate stability of the whole soil and the results are strongly dependent on the size chosen. Therefore, the de ...

Overuse of its water resources has caused its water level to drop, particularly in the east shore of that lake. This consequence has caused a serious environmental risk, but created a rare opportunity to investigate the spatial distribution of six iron forms and feature ...

The results of ²⁴¹Am and ²⁴¹Pu activity determination in soil samples sampled at the main testing sites of the STS are presented. ²⁴¹Pu/²⁴¹Am activity ratio is calculated. In most cases, on local sites, ²⁴¹Pu/²⁴¹Am activity ratio is in a rather narrow range, which mak ...

- Abstract:

One is how to construct a similarity index that can indicate not only the similarity of an environmental covariate between sites but also the directional difference of the covariate itself between sites and predict the soil property values beyond the range of sample values. Another is how to determine which soil samples should be u ...
