AB  - Incorrect and excess usage of pesticides during crop cultivation poses a serious 
      threat to human health and ecosystems. In this study, we tested for the presence 
      of 201 pesticide residues in 90 batches of Panax notoginseng (P. notoginseng) and 
      10 batches of planting soil. Pesticide residue characteristics and the 
      relationship between pesticides present in P. notoginseng and the soil were 
      discussed. Twenty-nine pesticides were detected in P. notoginseng samples and 15 
      pesticides were found in the soil samples. In P. notoginseng samples, the 68.9% 
      of the identified pesticides were fungicides, and six fungicides (procymidone, 
      iprodione, pyrimethanil, propiconazole, dimethomorph and tebuconazole) were found 
      in >90% of the samples. Nine insecticides were found, with one insecticide, 
      chlorpyrifos, detected in 93.3% of the P. notoginseng samples. The residual 
      concentrations of 17 pesticides were found at levels exceeded the "non-Chinese" 
      maximum residue levels (MRLs) for Ginseng and 17 pesticides were found at levels 
      exceeding the MRLs set by China for "pollution-free" P. notoginseng. We observed 
      no significant differences in pesticide residues were found on P. notoginseng 
      from different cultivation areas. We also analyzed the degradation kinetics of 
      pesticides in the soil, as well as their bioconcentration factors (BCFs), and 
      found that the fungicides iprodione and myclobutanil displayed strong uptake from 
      the soil to the root of P. notoginseng. Together, our data suggest that 
      fungicides should be considered as key monitoring substances in P. notoginseng 
      and planting soil.
