“…In addition, the surface charge of Fe 3 O 4 NPs decorated on SiO 2 ‐TiO 2 ‐NH 2 @Fe 3 O 4 is commonly neutral (pH 7) [23]. Hence, at pH 6, the surface of sorbent is positively charged (‐NH 3 + ) that leads to formation of electrostatic interactions with negatively charged analytes (atrazine (p K a = 1.65) [27], chlorpyrifos (no p K a ) [30], hexaconazole (p K a = 2.7) [31], and malathion (p K a = −6.8) [32]). Also, at this pH, NH 2 and remained OH groups of the sorbent interact with functional groups of the analytes containing N, O atoms via hydrogen bonding.…”

This study describes the synthesis and application of a magnetic amino-functionalized hollow silica-titania microsphere as a new sorbent for magnetic dispersive microsolid phase extraction of selected pesticides in coffee bean samples. The sorbent was fully characterized by Fourier-transform infrared spectroscopy, field emission scanning electron microscopy, transition electron microscopy, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometry techniques. Significant extraction parameters affecting the proposed method, such as extraction time, sorbent amount, sample solution pH, salt amount, and desorption conditions (desorption solvent and time) were investigated and optimized. All the figures of merits were validated in coffee bean samples under the matrix-matched calibration method. Linear dynamic ranges were 5-250 μg/kg with the determination coefficients (R 2 ) > 0.9980. The limits of detection for the pesticides of chlorpyrifos, malathion, hexaconazole, and atrazine were 1.42, 1.43, 1.35, and 1.33 μg/kg, respectively. Finally, the method was successfully applied for the determination of the pesticides in green and roasted coffee bean samples, and the obtained recoveries were in the range of 74-113% for spiked samples.The prepared sorbent could be used for the magnetic dispersive micro-solid phase extraction of pesticides in the plant-derived food matrix.

“…Liu et al [85] reported concentration-and exposure time-dependent bioaccumulation of two dinotefuran metabolites in E. fetida. Besides chlorpyrifos hydrophobicity, Svobodová et al [86] emphasized the role of soil organic matter and clay content in the bioavailability and bioaccumulation of this insecticide in E. andrei.…”

“…Most of the current studies do not consider the bioaccumulation of organic fungicides in terrestrial invertebrates, probably because of their complex analysis. The available studies are only focused on earthworms, showing, for example, bioaccumulation of tebuconazole, furalaxyl, pentachloronitrobenzene, and tolclofos-methyl in E. fetida [86,[122][123][124]. Moreover, fungicide bioaccumulation can be related to specific soil properties, such as organic matter and clay content, which can increase sorption and decrease fungicide bioavailability in soils [86].…”

“…Earthworms were obtained from plant nurseries maintained in the zoology area of the School of Biology of the National University of San Agustín, located in the city of Arequipa. For the present study, adult worms were used (Svobodová et al 2018, Xu et al 2019, which were raised in the Project Mercury research laboratory located at the Catholic University of Santa María (also located in Arequipa), in soils enriched with 10 % of organic material and humidity adjusted to approximately 40 %. The degradation runs were developed using a methodology of toxicity studies, present in the soil test established by the Organization for Economic Cooperation and Development (OECD 1984).…”

Pesticides containing organophosphorus compounds, such as chlorpyrifos (CPF), are frequently used in agricultural activities, and their use has been increasing due to the presence of multiple plant diseases which threaten the production of vegetable food products. As a result of this practice, the soils in question are often found to be contaminated due to the fact that these pesticides do not immediately degrade and hence remain for long periods of time. The objective of this study was to evaluate the degradation of CPF in the presence and absence of the worm Eisenia foetida (EF) in soils contaminated with 40 mg/kg of CPF during a 28-day period. The D group, whose soil was sterilized and in which no EF worms were present, yielded a CPF-degradation result of 33.68 %. The C group, in which the soil was unsterilized and there were no EF worms present, yielded a degradation percentage of 37.16 %. On the other hand, the B group, containing sterilized soil in which the EF worms were present, yielded a degradation percentage of 60.76 %. Finally, with the A group, in which the soil was unsterilized and EF worms were present, degraded in 74.85 %. Eisenia foetida (EF). En el grupo D, cuyo suelo estaba esterilizado y en ausencia de EF, se obtuvo una degradación del CPF de 33.68 %. En el grupo C, donde el suelo no estaba esterilizado y en ausencia de EF, se obtuvo un porcentaje de degradación de 37.16 %. Por otro lado, el grupo B, que contenía suelo esterilizado en presencia de EF, mostró un porcentaje de degradación de 60.76 %. Finalmente, el grupo A, cuyo suelo no estaba esterilizado y en presencia de EF, se degradó en un 74.85 %.
