Summary: Understanding the behavior of dicamba in Brazilian soils is crucial for efficient weed management. This research investigated the sorption, leaching, and degradation processes of dicamba in two types of soils, Oxisol and Ultisol. The study found that dicamba had low sorption capacity in both soils and showed higher mobility index in Ultisol compared to Oxisol. The degradation of dicamba was faster in the A horizon of both soils, while persistence was higher in the B and C horizons of Oxisol compared to Ultisol.

Summary: The use of glyphosate-based herbicides (GBHs) in industrial agriculture is causing a growing concern about the occurrence and spatial distribution of glyphosate and its principal metabolite, aminomethylphosphonic acid (AMPA), in the environment. A study conducted in Quebec, Canada found that 91% of soil samples contained detectable amounts of either glyphosate or AMPA, highlighting the potential spreading and persistence of these compounds in the environment. Glyphosate content was found to be significantly higher in clay soils rich in exchangeable cations.

Summary: The development of pore water pressure through seismic effect is a major cause of liquefaction failures in geotechnical engineering structures. Consolidated undrained cyclic triaxial tests were conducted to evaluate the normalized dissipated energy required for triggering liquefaction in homogeneous and stratified soil specimens. The test results showed significant variations in the dissipated energy of homogeneous specimens with different cyclic stress ratios and relative densities, and the thickness and location of the silt layer were found to be major influencing factors in stratified specimens. Empirical models were developed to estimate the normalized dissipated energy for both homogeneous and stratified conditions, providing more realistic results than other failure criteria.

Summary: In this study, the enantioselective accumulation and dissipation of BPMC in earthworms and various agricultural samples were investigated. The findings revealed that S-(+)-BPMC was preferentially accumulated in earthworms, but degraded faster in vegetables, fruits, and soils. Furthermore, S-(+)-BPMC showed lower cytotoxicity in neuronal cells compared to the other isomers. The results suggest the use of the pure S-(+)-enantiomer in agricultural management to reduce environmental risk.

Summary: Benzisothiazolinone degrades faster in soils with higher organic matter content, with anaerobic microorganisms playing a more significant role in degradation compared to aerobic microbes. Two metabolites were identified during the degradation process for the first time. Additionally, BIT exhibits relatively strong sorption and low persistence in soils, posing a low potential risk for groundwater contamination.

Summary: This study investigates the soils formed on pisoliths and sandstones in the Brazilian semiarid, providing insights into the pedosedimentary and paleoenvironmental histories of the Late Glacial/Holocene pedosequence. The formation of isolated plateaus in the Brazilian semiarid resulted from differential erosion. Pedogenesis and erosion/sedimentation-driven pedogenesis influenced the development of deep, dystrophic soils in the plateaus from the Late Glacial Maximum to the Holocene. The presence of similar parent materials and buried horizons suggests a consistent formation process in the plateaus.

Summary: A new type of magnetorheological fluid drive disk is designed to solve the problem of high-power magnetorheological fluid transmission heat dissipation. The characteristics of the flow field and temperature field of high power MR fluid transmission devices are analyzed, and the influence of factors such as rotating speed, inlet velocity, inlet position, diameter, and number of magnetic columns on the flow field are investigated. The experimental results show that the device has good heat dissipation performance and can transfer high-power torque.

Summary: The study found that biochar significantly influenced the dissipation and toxicity of atrazine in soil, with the most notable effects observed in sandy clay soil. The half-life and dissipation kinetics of atrazine varied in different soils, which were associated with atrazine partitioning, mineral content availability, and soil microbial biomass carbon.

Summary: This study utilized microstructure profiling to investigate vertical mixing in the interior Merrimack River plume during a tidal pulse. Multiple stratified shear mixing regimes were identified and evolved with time, including plume layer mixing, nearfield interfacial mixing, and tidal interfacial mixing. The findings highlight the previously unreported tidally modulated mixing within the river plume.

Summary: This study investigated the fate of dufulin enantiomers in aerobic soils using radioisotope tracing techniques. It was found that there were no significant differences in dissipation, bound residues (BR) generation, and mineralization between S-dufulin and R-dufulin. The soil characteristics primarily influenced the environmental fate of dufulin.

Summary: This study investigated the sorption of sulfadiazine (SDZ) in Brazilian soils with varying metal (oxy)hydroxide contents. The results showed that soils with high clay, organic matter, and metal (oxy)hydroxide contents had high SDZ sorption coefficients, while soils with low contents had low sorption coefficients.

Summary: This study utilized a mathematical model to predict the dissipation of atrazine in soils in Cordoba province, Argentina, based on soil organic carbon and land use as environmental variables. The results indicated that atrazine dissipation was faster in sites with previous gramineous crops and high soil organic matter.

Summary: Veterinary antibiotics are not metabolized completely in animals and can be dispersed into the environment when animal excretes are used as soil manures. This study investigated the persistence of tiamulin and tilmicosin from pig administration to fecal excretion and agricultural soils. The results showed that tilmicosin had higher levels of residues in feces compared to tiamulin, and different administration and storage conditions affected the persistence of these antibiotics in feces and soils.
