Dry–wet cycles increase pesticide residue release from soil [PDF]

open access: yesEnvironmental Toxicology and Chemistry, 2012
AbstractSoil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9–17 years) 14C-labeled residues of the herbicides ethidimuron (ETD)

Effect of wetting-drying cycles on soil desiccation cracking behaviour

open access: yesE3S Web of Conferences, 2016
Better understanding the desiccation cracking process is essential in analysing drought effects on soil hydraulic and mechanical properties through consideration of the atmosphere-ground interaction.

Effect of Wetting-Drying Cycles on Mechanical Behaviour and Electrical Resistivity of Unsaturated Subgrade Soil

open access: yesAdvances in Civil Engineering, 2019
Compacted soil is widely used in road and railway subgrade, while alternation of seasons can cause fluctuations in moisture content of soil (i.e., wetting-drying cycles) and influence the performance of soil.

Drying-Wetting Cycles: Effect on Deep Soil Carbon [PDF]

open access: yesSoil Systems, 2018
In the Southeast United States (U.S.), the climate is predicted to be warmer and have more severe drought in the summer. Decreasing rainfall in summer months should create more severe soil drying, which will eventually affect re-wetting cycles deeper in the soil profile.

Aging of recycled aggregates mortars by drying-wetting cycles

open access: yesConstruction and Building Materials, 2021
ABSTRACT: Due to the large amount of CO2 emissions produced nowadays by the construction sector, the scientific community is looking for measures that will bring constructions to the be as environmental-friendly as possible. One of the most popular lines of research is the use of construction waste as recycled aggregates for the production of recycled ...

Constitutive Relation with Double Yield Surfaces of Expansive Soil Improved by Lime and Flyash Subjected to Wetting-drying Cycles

open access: yes工程科学与技术, 2021
The elasto-plastic stress-strain constitutive relation with double yield surfaces of expansive soil improved by lime and flyash was studied based on the ellipse-parabola constitutive model.

Experimental study on influences of wetting-drying cycles on microstructure and water-retention characteristics of clay

open access: yesYantu gongcheng xuebao
The Long-term wetting-drying cycles can weaken the engineering characteristics of subgrade fillers, resulting in engineering disasters. It is necessary to study the effects of the wetting-drying cycles on their microstructure and water-retention ...

Influence of cyclic wetting‐drying on the mechanical strength characteristics of coal samples: A laboratory‐scale study

open access: yesEnergy Science & Engineering, 2019
Water‐coal interactions have gained much recent attention, although few studies focus on the strength of coal under wetting‐drying cycles. This study investigates changes in the microstructure and mechanical strength of coal that are induced by water ...

Nonequilibrium Wet–Dry Cycling Acts as a Catalyst for Chemical Reactions

open access: yesThe Journal of Physical Chemistry B
Recent experimental studies suggest that wet-dry cycles and coexisting phases can each strongly alter chemical processes. The mechanisms of why and to which degree chemical processes are altered when subject to evaporation and condensation are unclear. To close this gap, we developed a theoretical framework for non-dilute chemical reactions subject to ...
