    • World Journal of Microbiology and Biotechnology
    • The presence of herbicides residues in soil represents a serious problem for agriculture. Quinclorac is a common herbicide applied in rice field, but its residue can cause abnormal growth in successive crop of tobacco in Southern China. Remediation by microorganisms is considered to be an environmentally friendly method to remove such pollutants injury. The aims of this study were to obtain quinclorac remediation isolates and to investigate the possible mechanism(s) of remediation.

    • Food Control
    • In 2004, the Food Code of Korea adopted a multi-class multi-residue pesticide analysis method, which employed liquid–liquid extraction (LLE) and solid-phase extraction for sample purification. After several modifications, the LLE stage was replaced by the QuEChERS method in October 2021. Thus, in the current study a comparison was carried out between the new QuEChERS method and the conventional LLE method for the simultaneous analysis of multiple pesticide residues.

    • Mon, 06/06/2022 - 04:00
    • Food Science and Biotechnology
    • Chlorophyll-rich samples, such as kale, interfere with the analysis of residual pesticides and adversely affect the integrity of tandem mass spectrometers. Dispersed solid-phase (d-SPE) extraction using graphitized carbon black effectively removes pigments from kale extracts; however, it also reduces the recoveries of 30 pesticides. To overcome this, alternative sorbents, including ENVI-Carb, ChloroFiltr, and Z-Sep+, were evaluated in this study.
