Imbalances of soil available nutrients and soilborne diseases have seriously restricted the productivity of crops and jeopardized food security worldwide. Pyrroloquinoline quinone (PQQ), a redox cofactor in some bacteria involved in glucose metabolism and phosphorus mineralization, could be anticipated to alter soil ecosystems to a certain extent. However, there is limited information on PQQ defending soilborne pathogens and regulating soil main nutrients.

Cadmium (Cd) contamination in soil can cause serious environmental problems and threaten human health. Previous studies have shown that the reductive soil disinfestation (RSD) is regarded as an effective soil disinfection technology, which will affect the bioavailability of Cd. However, the influence of soil microorganisms and their metabolites on the morphologies of Cd during RSD treatment are still poorly understood.

Department of Applied Chemistry, College of Science, China Agricultural University, Beijing 100193, China.
A convenient and fast multi-residue method for the efficient identification and quantification of 72 pesticides belonging to different chemical classes in red and white grape wines has been developed. The analysis was based on gas chromatography tandem quadrupole mass spectrometric determination (GC-MS/MS). The optimization strategy involved the selection of the amount of multi-walled carbon nanotubes (MWCNTs) and the number of cleanup procedure cycles for multi-plug filtration cleanup (m-PFC) to achieve ideal recoveries and reduce the sample matrix compounds in the final extracts.

Article Synopsis
- The study examined how the process of making Chinese Baijiu affects the levels of eighteen pesticides in rice samples, showing significant reductions at each stage of production.
- Steeping removed 73.2% of flonicamid due to its water solubility, while steaming eliminated 32.0%-75.3% of other residues through evaporation or thermal breakdown.
- The most effective step was distillation, which accounted for over 90% of the remaining pesticide loss, indicating that the entire Baijiu production process greatly reduces pesticide levels and is crucial for safety assessments.
