Microbial Ecology: Spatial Aspects of Pesticide Degradation
… had a substantial effect on the extent of degradation, with an additional effect of moisture content. Simultaneous addition of the compound and the degrader to the soil resulted in reduced mineralization dependence on mass transfer and microbial motility. Solution phase concentrations of …

Exploring the emergence of pesticide degradation in the α/β hydrolase superfamily
… classes into the environment in the form of pesticides provides a dynamic testing ground to observe protein evolution in fast-forward mode. In this global experiment, we can observe the emergence of new enzymatic activities and compare the adaptability of different catalytic motifs. Among the …

Studies concerning the fate of atrazine and chlorpyrifos in a biobased pesticide waste disposal system
A disposal system for pesticide waste was examined for the ability to isolate waste pesticides onto lignocellulosic matrices, such as peat moss (PM) or steam-exploded wood fibers (SEW) by sorption processes, and to detoxify the pesticide during solid state fermentation (SSF) in contained …

Degradation Of Selected Organic Agrochemicals In Artificial Soil Slurry Systems By Anodic Fenton Treatment
… application of anodic Fenton treatment to the degradation of several probe agrochemicals in model soil slurry systems. A kinetic model, called the slurry AFT model, was developed to describe the degradation process in the slurry system. Effects of different model soil components, such as humic …

Sorption and degradation of pesticides in biopurification systems
The increasing use of pesticides in agriculture has given rise to a situation in which countries now have to cope with the problem of residues of these compounds in ground and surface water. 40-90% of surface water contamination is caused by direct losses (e.g. spills during filling operations, …

Ensuring safety in soy: a review of chlorpyrifos detection and mitigation for consumer confidence
… methods to ensure crop success, including pesticide use. Chlorpyrifos (CPF), a widely used pesticide, remains under regulatory scrutiny due to concerns about its safety and environmental impact. After alternating between federal approvals and restrictions, the United States (U.S.) …

Lights, Camera, Reaction! The Influence of Interfacial Chemistry on Nanoparticle Photoreactivity
… and bacterial inactivation, and contaminant degradation. Physical characterization of NPs included light scattering, electron microscopy and electrophoretic mobility. These systematic investigations into the effect of functionalization, sorption, and aggregation on NP aggregate structure, …
