For the insecticide chlorpyrifos and cypermethrin II, significant reductions below the limit of quantitation were revealed when treated with all fining agents except bentonite, where effects were also observable, but with smaller reductions. For indoxacarb, the reduction was most significant with the charcoal product Grandeco, followed by Fluopyram, Granucol GE, the two yeast cell wall products Absolut Wein and Reskue, and the two mixed products Purity D and CarboTec GE. No significant reduction was detected for NaClit. There was also a significant reduction in chlorpyrifos_methyl with all treatment agents (except bentonite for red wine). Interestingly, here the two yeast wall products Absolut Wein and Reskue showed a greater reduction than the plant fiber and mixed products and a comparable effect to the two charcoal products Grandeco and Granucol GE.
