The dissipation, processing factors, metabolites, and risk assessment of pesticides in honeysuckle from field to table

Globally, honeysuckle is consumed as a food and administered as a medicinal agent. However, pesticide residues in honeysuckle limit its application and development of the honeysuckle industry, affecting food safety and endangering human health. Here, the degradation kinetics of 11 typical pesticides, including insecticides, fungicides, and an acaricide, in honeysuckle were investigated. The half-lives of pesticides in Henan and Liaoning fields were 1.90-4.33 and 2.05-4.62 d, respectively. The processing factors (PFs) of these pesticides after oven, sun, and shade drying ranged from 3.52 to 11.2. After decocting, the PFs of the pesticides were <1. Twent y degradation products were identified using ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrome t r y , and pathways were proposed based on drying and decoction. The ecotoxicities of the degradation products were evaluated using the Toxicity Estimation Software Tool. Finally, the acute hazard indices of these pesticides, as determined via dietar y exposu r e assessment combined with the PFs, were 0.227 and 0.911 for adults and children, respectively. Thus, special populations, such as children, require particularly caref u l risk control in terms of dietary exposure.

Automated summary

The degradation kinetics of pesticides in honeysuckle were investigated, and it was found that pesticides had short half-lives in honeysuckle while showing high processing factors during drying and decoction. The ecotoxicities of degradation products were evaluated, and special populations such as children require careful risk control in terms of dietary exposure.
