Degradation of Isotianil in Water and Soil: Kinetics, Degradation Pathways, Mechanisms, and Ecotoxicity Assessments.

Pesticides are transported and transformed in soil and can enter surface water through various pathways. They undergo hydrolysis, oxidation, and photoconversion in surface water. Isotianil is a new fungicide that effectively controls rice blast.

Bioconcentration, oxidative stress and molecular mechanism of the toxic effect of acetamiprid exposure on Xenopus laevis tadpoles.

Acetamiprid is a neonicotinoid commonly detected in aquatic ecosystems, with residual concentrations of up to 0.41 mg/L in surface water, posing a threat to the health of nontarget aquatic organisms. However, studies on the potential toxicity and underlying mechanisms of action of acetamiprid on nontarget aquatic organisms are limited.

The built environment, purpose-specific walking behaviour and overweight: evidence from Wuhan metropolis in central China.

The impact of objective and subjective environmental factors on health outcomes has been a topic of significant debate, with a growing body of research acknowledging the role of a physically active lifestyle in promoting health. However, consensus regarding their precise influence remains elusive. This study contributes to these discussions by exploring how individual health outcomes correlate with transport and leisure walking behaviours, set against both the objective and subjective aspects of environmental influences in the context of Wuhan, an inland Chinese megacity.

Characterization of Sulfoxaflor and Its Metabolites on Survival, Growth, Reproduction, Biochemical Markers, and Transcription of Genes of .

Sulfoxaflor is a promising neonicotinoid. However, the negative implications of sulfoxaflor on nontarget aquatic organisms have been rarely studied. In this study, the risks of sulfoxaflor and its main metabolites X11719474 and X11519540 on were characterized, including acute toxicity, reproduction, swimming behavior, biochemical markers, and gene transcription.

Distribution and assessment of heavy metal in sediments of Malacca Strait.

In this study, we explored the heavy metal elements in 42 surface sediments from the Malacca Strait in terms of distribution, controlling factors, environmental quality, and primary sources. An analysis of grain size revealed finer sediments near the coast of Malaysia, which gradually thickened toward offshore. In addition, heavy metal elements were abundantly distributed near the coastal area of Malaysia, with a gradual decrease toward the sea; their content increased within waters close to the Perak estuary.

Time behavior and capacitance analysis of nano-Fe3O4 added microbial fuel cells.

The addition of nano Fe3O4 is beneficial to boost the transient charge storage of the anode accompanying with the enhancement of power performance in microbial fuel cells (MFCs) in our previous study. Here we found that both the anodic open circuit potential and the current increased when comparing the AcFeM (Fe3O4 added activated carbon anode) with the AcM (activated carbon anode), indicating that the Fe3O4 dynamically accelerated the anodic electron transfer although it thermodynamically limited the anode potential. The net storage capacity initially increased followed by a decrease with the maximum capacitance of 574.
