“…In this study, CPM had a greater R f values in Red soil than in Black soil.competitive adsorption between CPM and Cu 2+ ions for soil adsorption sites[8], thereby increasing the mobility of CPM through soils. Facilitated transport of pesticides in the presence of Cu had also been confirmed by other studies.…”

Pesticides and heavy metals pollution in soil environment has become a serious problem in many countries including China. Two different types of soils were used in this study to assess whether high soil copper (Cu) concentrations may affect the mobility of cypermethrin (CPM). The results show that CPM had a greater R f values in Red soils than in Black soils. Compared with distilled water, the mobility of CPM was enhanced by Cu. The results will provide more information about the potential ecological risk of chemicals on surface and groundwaters.

“…However, methomyl was the least pesticide among all pesticides tested in the recovery process by Ch‐PDMS MNPs. Lambda‐cyhalothrin not detected by HPLC in water phase at all tested concentrations that may be due to it has low solubility in water and high octanol/water partition coefficient value . The descending order is followed by abamectin, fenamiphos, thiophanate‐methyl, imidacloprid, and diazinon, respectively.…”

Novel chitosan‐siloxane functionalized magnetic nanoparticles including chitosan polydimethyl siloxane, chitosan octadecyl siloxane, and chitosan phenyl siloxane were prepared and characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and Zeta potential measurements. The particles were prepared from Fe3O4 functionalized by siloxane derivatives followed by coating with chitosan through a crosslinking mechanism. Infrared spectroscopy was used to confirm the reaction and conjugation between the three layers of the crosslinking chitosan, siloxane and magnetic nanoparticles. The nanoparticles were applied as effective sorbents for extraction of seven pesticides (abamectin, diazinon, fenamiphos, imidacloprid, lambda‐cyhalothrin, methomyl and thiophanate‐methyl) from water. The particles were used in a magnetic dispersive solid‐phase extraction technique and solid‐phase extraction cartridge. The pesticides were then quantified by using high‐performance liquid chromatography with limit of detection of 0.002–0.046 μg/mL, limit of quantification of 0.006–0.154 μg/mL and excellent linearity in the range of 0.0125–0.15 μg/mL with correlation coefficients (R2) higher than 0.999. The magnetic nanoparticles showed a high recovery efficiency compared to standard octadecylsilane (Sigma–Aldrich) for some pesticides. The results indicated that these methods achieved the rapid and simple extraction of small quantities of adsorbents and solvent with a high recovery rate.

“…The sorption of organic contaminants may be reduced when copper is present (Pei et al 2006;Liu et al 2009), because the positively charged metals have stronger adsorption affinity for sorption sites than neutral organic compounds, and thus occupy preferably those sorption sites or release the already sorbed organic compounds. On the contrary, other reports indicate an increase in the retention of organic compounds in the presence of metals such as copper, zinc, or lead (Gao et al 2006).…”

The mineralization of 14 C-labeled methyl parathion, in a soil from a semiarid Mediterranean area, was followed by a simple method. This method consisted in trapping evolved CO 2 in a NaOH trap, using common laboratory glassware and low quantities of reagents. Volatiles were trapped in polyurethane foams, which are cheap and easy to handle. The influence of soil water content (10-20%) and the addition of surfactants [Aerosol 22 and hexadecyl trimethyl ammonium bromide (HD)] and metals (Cu and Zn) were assessed. Different models were applied to evaluate parathion mineralization kinetics. Mineralization kinetics was initially faster for 20% soil water content, although the final mineralization extent was similar in the range of tested soil water content. Surfactants behaved differently: HD decreased mineralization rate while Aerosol 22 did not affect parathion mineralization. A bimetal Cu and Zn solution led to a significant decrease in methyl parathion mineralization, which persisted when applied together with HD. Results suggest a possible reduction of pesticide availability in soil or a direct effect of the exogenous chemicals on soil microbial community.
