“…However, after UV degradation, its degradation components inhibited this change, which may be a change in structure that reduced the toxicity. Ben Salem et al [14] confirmed the hydrolysis of the chloropyrifos aliphatic chain after ionizing radiation and UV treatment. Some studies showed that when the maximum emission peak of BSA was redshifted, the hydrophobicity of the microenvironment of amino acid residues decreased, and the polarity increased.…”

Pesticides play a pivotal role in modern agriculture, but their potential environmental and health impacts necessitate a comprehensive understanding of their interactions with biological molecules. Beta-cyfluthrin, a widely used synthetic pyrethroid insecticide, is known for its efficiency in pest control. However, its interaction with bovine serum albumin (BSA), a crucial transport protein in living organisms, has not been extensively studied. The interaction between beta-cyfluthrin, a prominent synthetic pyrethroid insecticide, and bovine serum albumin (BSA) was comprehensively investigated using fluorescence spectrometry. Furthermore, the influence of ultraviolet (UV) degradation on the interaction parameters was explored, enhancing our understanding of the impact of environmental conditions on this interaction. The Stern–Volmer equation was employed to determine quenching constants, revealing that the fluorescence quenching mechanism primarily involved static quenching. The temperature variations were studied, showing an increase in the binding constant with rising temperature prior to degradation, while post-UV degradation, an inverse correlation between the binding constant and temperature was observed. The thermodynamic parameters were derived through appropriate equations, unveiling the underlying reaction forces. In the absence of degradation, hydrophobic interactions dominated, whereas after UV degradation, interactions shifted to hydrogen bonding and van der Waals forces. The findings elucidate the nuanced effects of UV degradation on the interaction between beta-cyfluthrin and BSA. This study furnishes critical insights that serve as a scientific foundation for pesticide production and application strategies, accounting for the influence of UV degradation on the intricate interplay between pesticides and BSA.

A comparative study was carried out of sonochemical (SCh), electrochemical (ECh) and sonoelectrochemical (SECh) strategies for the degradation of the fungicide thiram in dilute aqueous solution. The SCh and SECh studies were performed using a sonicator equipped with an 11 mm titanium-alloy probe and operated at 20 kHz with a power intensity of 523 W cm(-2). In the ECh and SECh investigations, galvanostatic electrolyses were implemented using a single compartment electrochemical cell with a boron-doped diamond electrode as anode and applied current densities in the range 10-50 mA cm(-2). For these processes, the decrease in concentration of thiram was monitored by high performance liquid chromatographic (HPLC) analysis and values of current efficiency and energy consumption were determined. The results showed that the rate of degradation of thiram and the amount of energy consumed were directly proportional to the applied current density, while current efficiency was inversely related to current density. The kinetics of thiram degradation followed a pseudo first order model with apparent rate constants in the region of 10(-3)min(-1). Thiram in aqueous solution was subjected to "exhaustive" degradation by ECh and SECh processes for 5h at applied current densities of 35 mA cm(-2) and the intermediates/byproducts so-formed were identified by HPLC-mass spectrometry. Mechanisms of the degradation reactions have been proposed on the basis of the results obtained.
